+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to capture.</li>
+<li>The game is won by checkmating the opponent's King, <b>or by checking it for the third time</b>.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+You lose when being checked for the third time.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+<p>
+It is not possible to force checkmate on a bare King with just a single Ferz, Elephant or Knight (in addition to your own King).
+Two Knights or two Ferzes cannot do it either.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>Captures destroy ('explode') both capturer and victim, and also destroy all non-Pawns adjacent to the capture square.
+<li>The game is won by destroying the opponent's King.</li>
+<li>Destroying your own King is not allowed.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+Pieces explode on capture, destroying everything in the area including themselves.
+You win by destroyig the King rather than checkmating it;
+exposing your King to destruction is not forbidden (just stupid).
+</p>
+<h3>Strategy issues</h3>
+<p>
+Since any capturing piece destroys itself in the explosion, Kings can never capture.
+</p>
+<p>
+A King taking shelter next to the opponent's King (which, after all, cannot capture)
+is immune to capture, as such a capture would destroy your opponent's King in the explosion.
+So many end-games (even KQK) can be drawn by tailing the opponnet's King!

+<title>(Extended) Betza notation</title>

+<body>
+<h1>Extended Betza notation</h1>
+<p>
+Ralph Betza invented a compact notation to encode moves of a piece,
+which is now in wide-spread use for description of Chess variants.
+This page describes a version of it that has been extended in several ways.
+Some of these extensions were embraced from another proposed extension scheme,
+'<span style="background: #00FFFF;">Bex notation</span>' by David Howe, others are entirely new.
+These new extensions from the original Betza notation are <span style="background: yellow;">marked in yellow</span>.
+</p><p>
+Betza notation decomposes the piece into 'atoms',
+which represent the set of all (8-fold-)symmetry-equivalent moves of a certain distance.
+For example all eight Knight moves, or all diagonal moves of the King.
+Each 'atom' is written as a single capital (e.g. N for the Knight moves),
+which is very efficient when you are dealing with pieces that are maximally symmetric
+(which most pieces indeed are).
+Atoms refer to single unblockable leaps of a certain distance.
+Pieces that can repeat the same leap again and again until they encounter an obstacle
+(sliders or riders, such as Rook)
+are very common.
+Those moves are indicated by writing the number of steps the piece can maximally make behind the atom,
+<span style="background: yellow;">where '0' can be used to indicate 'any number of steps'</span>.
+</p>
+<p>
+The choice to treat moves as sets that go in all directions goes at the expense of the compactness when dealing with asymmetric pieces.
+(This is a cheap price to pay, as asymmetric pieces are much less common than fully symmetric ones.)
+To describe moves of asymmetric pieces Betza notation uses <i>lower-case prefixes</i> to identify which sub-set of the atom we mean.
+Such as f (forward) or r (right), or combinarions of those like fr.
+E.g. fR decribes a 'Rook' that only moves in the forward direction (i.e., the Shogi Lance).
+Lower-case prefixes are also used to specify the move is not a general one
+(i.e. valid as capture and non-capture, the normal situation in Chess-like games),
+but can only be used in limited ways (e.g. capture only, non-jumping, capture after jumping).
+</p>

+For longer-range atoms no letters are defined.
+In the rare cases they occur, <span style="background: #00FFFF;">these can be written using the numeric coordinates of their leap vector</span>,
+e.g. (4,1) for the Giraffe leap.
+Note this still implies the move goes in all directions (i.e. (4,1) also means (4,-1), (-4,1), (1,4), ...),

+So even prefixes with opposite meaning are not really conflicting;

+(E.g. mc would mean both non-capture and capture, which is the default in absence of prefixes anyway.)

+For example, fmWfcF is a Pawn: non-captures forward to a W square, captures to the two forward F squares.
+Pretty complicated, but the Pawn is a very complex piece (asymmetric, and divergent capture/non-capture).
+Note that fr and rf are not the same on 'oblique' (= not orthogonal or diagonal) atoms, which have 8 moves,
+and that they might not be what you intuitively think, as fs = fl + fr.
+<h3>Grouping</h3>
+<p>
+<span style="background: #00FFFF;">Grouping of atoms, modifiers and exponents is possible with parentheses</span>.
+This can be done for readability,
+or for overruling operator priorities.
+(fmW)(fcF) might read more easily than fmWfcF.
+The parentheses do not have any meaning in themselves.
+'Distributivity' also works for modifier prefixes:
+m(AB) where m is a string of modifiers and A and B are atoms, (or expressions grouped in parentheses),
+is defined to mean mAmB.
+Some shortcuts for commonly used combinations of atoms exist;
+these can be seen as implicit grouping of the involved atoms.

+<h3>Chaining moves</h3>
+<p>
+When a number of atoms is concatenated, like WF, it joins their move sets.
+So the piece described by WF moves either as W or as F, i.e. one step diagonal, or one step orthogonal.
+That means it is the King of orthodox Chess!
+(From the notation you cannot see whether it is royal yet;
+the main purpose of the notation is to convey how it moves.
+<span STYLE="background-color: yellow;">But a 'k' prefix could be used to indicate royalty</span>, when this is of relevance.)
+</p>
+<p>
+It is also possible to specify that certain moves have to be performed sequentially, one after the other.
+For instance because something of importance happens or should be noted on an intermediate square.
+Such as for pieces that can be blocked on squares they cannot visit ('lame leapers'),
+or that have to hop over other pieces in a specific pattern.
+The simplest example of this, however, is repetition of the same step in the same direction,
+as in sliding or riding pieces, such as a Rook.
+The far moves of such a piece can indeed be blocked by an obstacle closer by on their path,
+although it can then always reach that square itself as well.
+Such moves are indicated by 'exponentiation': a number after the atom indicates how often the step may be repeated.
+E.g. F3 would be a piece that slides diagonally (i.e. like a Bishop), upto a maximum of 3 steps.
+To indicate an arbitrary number of steps can be taken, we use 0 (zero) for the exponent.
+(This because infinity is not in the ASCII character set, and 0 would be pointless when taken at face value.)
+So W0 would be the Rook, sliding arbitrarily far orthogonally, and F0 the Bishop.
+(Old notation for this would be WW and FF, but in the extended context these would be troublesome.)
+</p>
+Not all multi-step moves are as regular as simple sliders, however.
+Some 'bent' sliders can turn corners, for instance.
+The 'Griffon' is an example that first moves one step diagonally, and <b>then</b> continues outward as a Rook.
+It does not have to go beyond the corner, though; just like a normal Rook it can make the first step of its move only.
+And if it encounters something on that first step, it is blocked, and never gets to the rooky part of its move.
+To describe this trajectory we cannot use exponentiation, but have to explicitly write the chain: FtR.
+Here the 't' is the chaining operator, that distinguishes this from FR,
+which would mean a piece that steps one diagonally <b>or</b> moves like Rook (a Shogi Dragon Horse).
+The 't' is because of 'and <b>t</b>hen', but also because the move could be <b>t</b>erminated at that point,
+and there is no requirement to visit the later parts of the specified trajectory.
+</p>
+<p>
+There are other forms of chaining, where the 'connecting square' can not be visited.
+(I.e. no termination there.)
+The Xiangqi Horse moves one orthogonal step, and then (without stopping) one step diagonally outward,
+mimicking the move of a Knight, but blockable on the intermediate square.
+This is written as the chain W-F.
+The chaining operator '-' indicates the move cannot be terminated at that point (ending on the connection square),
+but must continue.
+If it cannot, because the square was occupied, the move described by the chain is considered blocked, and cannot be made.
+</p>
+<table border="1"><tr><th colspan="3">
+Overview of chaining operators
+</th></tr>
+<tr><td>t</td><td>then</td><td>terminate on connection square (if empty or enemy) or continue (if empty).</td></tr>
+<tr bgcolor="FFFF00"><td>-</td><td>block</td><td>must continue if connection square empty; otherwise entire path is considered blocked</td></tr>

+</table>
+<p>
+Chaining implies continuation in the most similar direction.
+Should you need to deviate from that, e.g. because the trajectory doubles back on itself,
+directional modifiers must be used.
+The continuation steps are to be described in a coordinate system relative to the previous step, however.
+So W-rW-lW makes one step, (say moving North), then turns right for another step (moving East), and then turns left compared to that second step,
+meaning it is moving North again!
+So in the end you arrive at (1,2), over (0,1) and (1,1).
+This is a Knight move that can only be made if both the intermediate squares are empty,
+even worse than the Xiangqi Horse (which at least did not care about (1,1))!
+The latter would be described by W-F.
+The F after '-' would by default mean fF, and in the orientation of the preceding orthogonal step
+this would imply a pair of outward moves, fl + fr.
+</p>
+<p>
+Some examples that use the other operators:
+Q+K is the Grasshopper: it must move as Queen to an occupied square (the 'support'),
+(the first one it encounters, as Queens do not jump!),
+and then continue with a single K step in the same direction (leaving the occupant of the square alone),
+to land on the square directly behind the support.
+where it can capture or just move.
+mRcR+R is the Xiangqi Cannon: the first mR specifies its non-capture move, which is that of a normal Rook.
+The concatenated cR+R is the capturing alternative;
+it moves as R to an occupied square, and then continues as R in the same direction for a capture.
+Note that the 'c' prefix applies to the complete R+R path (a once jumping Rook);
+the operator priorities are such that the binary operators t-+xdy couple more tightly than the prefix modifiers mc.
+The latter are only allowed in front of a complete path, to specify what you can do at the end of it,
+and not on individual steps of the path, where the chaining operators already specify this.
+</p>
+<h3>Weird captures</h3>
+<p>
+The x operator allows description of pieces with unconventional capture,
+as it specifies moving away from the capture square.
+Normal in Chess is of course that you only captured what was on the square you end on.
+But even in orthodox Chess e.p. capture exists as an exception to that.
+It could be written as frmWxlW, which, as we have seen, means frm(WxlW)
+This expreses capture through a W step, and then turning left for a second W step,
+so that overall you make an F step in an L form.
+The frm prefix to this F step means that it can not capture <i>on the final square</i>
+(the Pawn in e.p. capture always goes to an empty square),
+to your forward right.
+I.e. you started moving right, then turned left to move forward.
+So the continuation square you pass over to remove the Pawn is to your right.
+(There is no way to express that you can only do this to Pawns, however, let alone to Pawns that just made a double push.)
+</p>
+<p>
+This shows the general encoding strategy: if you capture pieces not on your destination square, as 'side effect' to the move,
+you lay out a path that tramples all the pieces that are captured, so that the sub-steps are all normal replacement captures.
+E.g. a Checker would be fmFfmFxF. There the fmF part is the non-capture move,
+but the interesting part is the capture:
+one step diagonal (which must be to an occupied square, which we capture),
+and then straight on (which is now 'forward' in the local frame of reference set up by the first step)
+to the next square, for an overall A step.
+This step must be fmA, i.e. in one of the forward diagonal directions, not capturing anything on the square where it lands.
+'Rifle capture' by a Rook would be RxebR, i.e. first capture something in the normal way,
+and then manditorily withdraw in the direction from which you came (b) by an R move of the same length.
+No overall move, but the victim is gone!
+A Ultima Withdrawer, which destroys the adjacent piece from which it moves away, would be written as
+mQmKxbK-Q. The capture part, m(KxbK-Q) specifies capture to the adjacent piece, reversing that step (b) to your square of origin,
+and then mandatorily continuing in that direction with a Queen non-capture move (the victim already in your pocket).
+The hit-and-run or double capture of a Lion would be KxaK: capture the adjacent piece,
+after which you must continue by another King step in any direction relative to the first, capturing a second victim or just moving.
+ven the rifle capture (igui) is included in this.
+Its turn-passing move would be K-bK.
+Which is different from O, because it can only be done if the Lion is adacent to an empty square,
+while a piece that has an O atom can pass uncondiionally.
+For definiteness, when directional modifiers apply to a path that results in a return to the starting square,
+they will be referenced to the direction of the first step of the path.
+</p>
+<h3>More about exponentiation</h3>
+<p>
+Exponentiation by default implies repeated application of the 't' operator.
+But it can be used to indicate repeate application of other operators too.
+<span style="background: #FFFF00;">We define AmN, with A an atom or a group within parentheses, m a string of modifiers, and N a number,
+to mean AmAmAm...mA with N factors A and N-1 operators between them</span>.
+If the modifier string m does not contain one of the chaining operators, it is prefixed with the default 't'.
+If it does not include any directional modifiers, it is suffixed with 'f'.
+So W3 means WtfWtfW, 1 to 3 orthogonal steps in the same direction (which is what the 'f' specifies).
+But W-3 would mean W-fW-fW, which is exactly 3 such steps.
+And Wx3 would be exactly 3 steps where the first 2 mandatorily capture.
+</p>
+<p>
+By including directonal indicators, you can describe curved trajectories.
+Nrf8 would mean NtrfNtrfN..., upto 8 Knight moves, each consecutive move bending ~45 degrees right from the previous one
+(because that is what rf means; the first opportnity to the right that is not straight ahead).
+This describes the Rose!
+Circular riders fit into the system, and there is no need for a separate prefix to describe them.
+With grouping you can do more: (FtlF)r0 expands to FtlFtrFtlFtrFtl..., an arbitrary number of diagonal steps,
+that alternately turn 90 degrees left or right.
+In other words, the Crooked Bishop.
+There is also no real need for the z prefix in this extended Betza notation.
+The exponentiation can describe it much more precisely,
+specifying exactly how Crooked it is.

+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move to the c1/c8 or i1/i8 in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square on the other side next to the King.
+This is only allowed if all squares traveled through by King and Rook are empty (after their removal),
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<p>
+You can use the New Shuffle dialog to control the randomization of the initial position.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The Chancellor and Archbishop pieces are extra, and the board is expanded to accomodate them.
+Castling is generalized to allow it with non-standard placement of King and Rooks.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+The Archbishop can force checkmate against a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As Chancellor and Queen are nearly equal in value to Queen, under-promotion is very common,
+and there is virtually never any need to promote to R, B or N.
+</p>
+<p>
+The super-pieces (Q, C, A) devaluate by the presence of lower-valued opponent pieces.
+As a result trading Q for R + B is in general a good trade when you still have both J,
+as the latter gain in value by eliminating the opponent's R and B,
+which is more compensation than the intrinsic value differene between Q and R + B.

+<h1>Chess with Different Armies</h1>
+<p>
+This is actually a group of variants.
+It defines a number of 'armies', each containing of an orthodox King and Pawns,
+plus 7 other pieces of 4 different types.
+The orthodox FIDE army, with pieces Q, R, B and N, is one example of this.
+But there are many armies considting of four completely different pieces,
+together of approximately equal strength as the FIDE army.
+Here we discuss three possible realizations of this.
+</p>
+<p>
+Each of these four armies can be pitted against each of the others,
+with either color.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice <b>from their own army</b> when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can (in general) move two squares in the direction of a corner piece that has not moved before,
+in which case that corner piece is moved to the square next to the King on the other side.
+This is only allowed if all squares traveled through by King and corner piece are empty (after their removal),
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+When the corner piece is color-bound, however, the King moves 2 <b>or 3 squares</b>, subject to all other rules mentioned above,
+to make sure the piece it castles with stays on the same color.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>Any army can be pitted against any other.</li>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+Man of the pieces in the various army are quite exotic even by the standards of Chess variants,
+and XBoard does not know them.
+So Chess with different Armies has to be played with legality testing off,
+using pieces XBoard does implement for different purposes.
+CwDA is also not an variant name known to XBoard;
+it has to be played as the catch-all variant 'fairy'.
+This variant can mean anything as far as XBoard is concerned;
+you have to tell the engine what you actually want to play,
+and then the engine will tell it to XBoard (i.e. which piece symbols to use, in which initial setup).
+So CwDA cannot be played without an engine that knows how to play it.
+</p>
+<p>
+Fairy-Max implements various versions of CwDA.
+With a combobox in the Engine Settings dialog you can select which version you want to play
+(e.g. Clobberers-Nutters) as variant fairy.
+When you then select 'fairy' from the New Variant dialog
+(or start a New Game when 'fairy' was already selected)
+the engine will setup the game for the selected armies.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+Except for the FIDE army, all armies consist of pieces (not King and Pawns) that move in completely different ways.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+It is not possible to force checkmate on a bare King with just a single Elephant or C or L (in addition to your own King).
+A pair CC, LL or CL on unlike colors can force checkmate without help of their King.
+A pair of Elephants can checkmate with help of their King.
+It is not possible to force checkmate on a bare King with just a single Fibnif or a pair of them (in addition to your own King).
+All pieces of the Rookies army can force checkmate against a bare King.
+</p>
+<p>
+Bishops, C and L are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+Combining other color-bound pieces on unlike colors is expected to involve even larger bonuses.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move <b>three</b> squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square next to the King on the other side.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Chancellor and Archbishop pieces are extra, and the board is expanded to accomodate them.
+To handle the larger board width, the King moves 3 squares on castling.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+The Archbishop can force checkmate against a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As Chancellor and Archbishop are nearly equal in value to Queen, under-promotion is very common.
+</p>
+<p>
+The super-pieces (Q, C, A) devaluate by the presence of lower-valued opponent pieces.
+As a result trading Q for R + B is in general a good trade when you still have A and C,
+as the latter gain in value by eliminating the opponent's R and B,
+which is more compensation than the intrinsic value difference between Q and R + B.

+Chu Shogi was already known in the year 1250,
+and has been the dominant form of Chess in Japan for many centuries.
+In recent time, after the invention of piece drops, it was overtaken in popularity by modern Shogi.
+It is still widely played in Japan, though.

+
+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns move <b>and capture</b> straight ahead.</li>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>The game is won by capturing the opponent's only King.</li>
+<li>Pieces promote at the end of a move into the promotion zone.</li>
+<li>The promotion zone consists of the last four ranks.</li>
+<li>Pieces promote only once.</li>
+<li>Perpetual checking is forbidden, and would be ruled a loss on the 4-fold repeat.</li>
+<li>Other repetitions lose for the side that creates them.</li>
+</ul>
+<h3>Lion moves and Stinging pieces</h3>
+<p>
+Some pieces can make two moves per turn.
+That means they can also capture two pieces per turn,
+one on the square they move to (as normal), and one 'en passant' on the transit square.
+They can also capture on the transit square, and move on to an empty square ('hit and run'),
+or capture and move back to where they came from ('shooting' the piece from a distance, as it were).
+Of course they can also capture a single piece in the normal Chess manner.
+In that case the transit square is immaterial.
+</p>
+<p>
+The Lion can make such double moves as two King steps,
+i.e. in all directions, and arbitrarily changing direction between them.
+The Unicorn and the Eagle can only make double moves in one or two directions respectively.
+They can not arbitrarily change direction, but only reverse it (or not), so they do stay on the ray in that direction.
+But that way they can still make double, hit-and-run, shooting or normal captures.
+All these pieces can also jump over the transit square, i.e. reach the distant two-step destination in a single jump.
+Finally they can also just make a step to an adjacent square, refraining from taking a second step.
+</p>
+<h3>Restrictions on Lion capture</h3>
+<p>
+There are rules to make Lion trading very difficult, in order to keep the Lions in play.
+Basically they specify that two Lions cannot be captured in consecutive half-moves.
+When the first capture is Lion x Lion from a distance, it is forbidden to play it if recapture of the capturing Lion is possible.
+When another piece captures a Lion, it is just the other way around:
+then the 'counterstrike' by a non-Lion against the Lion is forbidden.
+One possibility left open is thus when you capture an adjacent Lion.
+But then you would in general be foolish to allow recapture,
+as you could take the Lion hit-and-run fashion, fleeing to a save square.
+An exception to the rule is when a valuable opponent piece (i.e. not a Pawn or Go Between) forms a 'bridge' between the Lions;
+you may then capture that piece in the first leg of the double-move,
+and then take the opponent Lion with the second leg.
+Then the opponent can recapture, but he will have lost a valuable piece.
+</p>
+<h3>XBoard interface issues</h3>
+<p>
+This game has to be played with the option Show Target Squares on!
+This option will cause marking of the target squares of any piece you select or grab,
+by the engine (with legality testing off) or by XBoard (legality testing on).
+Moving to a square marked in cyan will be interpreted not as the final destination,
+but as the transit square after the first step of a multi-leg move.
+XBoard will then highlight the possible destination squares of the second leg from there.
+Should you want to end on the cyan square, you click it again, (it will be no longer marked in cyan),
+and XBoard will terminate the move after the first leg.
+You can also move back to the starting square, to 'shoot' the opponent piece from nearby.
+</p>
+<p>
+With Detour Underpromotion on, XBoard will assume by default that every piece that enters the zone promotes.
+Should you want to defer in this mode, you should use a click-click move,
+and when you make the click on the promotion square,
+move the mouse down before releasing the button.
+If you move enough the piece on the promotion square will change back to the unpromoted form,
+and then you can release.
+With Detour Underpromotion off, you will automatically get a promotion popup that asks whether you want to promote or defer.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+Except that there are also Kings, Queens, Rooks and Bishops, not much is the same.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Piece with no sliding forward moves are hard to promote,
+but promotion of forward sliders is practically unavoidable.
+</p>
+<p>
+You can have two Kings by promoting the Elephant, in which case the opponent would have to capture both in order to win.

+<h1>Chu Chess</h1>
+<p>
+Chu Chess is an intermediate between (Mighty-Lion) Chess and Chu Shogi.
+It was designed for over-the-board play with the aid of two Chess sets, some draughts chips,
+and an International-Daughts (10x10) board.
+Pieces placed on a draughts-chip pedestal would represent 'crowned' pieces,
+i.e. pieces that in addition to their normal Chess moves would also be able to move as an orthodox King.
+With the exception of the Knight on a pedestal, which would not only get the extra King move,
+but the full power of a Chu-Shogi Lion.
+(To highlight its importance, it could be put on top of a stack of draughts chips.)
+This variant can be played in two versions, differing only in promotion rules,
+which can be either Chess-like or Shogi-like.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote asthey promote in orthodox Chess piece of choice when they enter the promotion zone (in the Chess-like version).</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move <b>three</b> squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+<li>The promotion zone is three ranks deep.</li>
+<li>You cannot promote to Lion if you already have one.</li>
+</ul>
+<h3>Chess-like or Shogi-like promotion</h3>
+<p>
+In the Chess-like version only Pawns promote.
+You can choose what piece to promote to, but promotion is mandatory:
+you cannot stay a Pawn.
+In the Shogi-like version other pieces can also promote, but there is no choice:
+pieces promote to their 'crowned' versions, and acquire the moves of a King on top of their own that way.
+Pieces that already had all King moves cannot promote.
+Thus a Commoner cannot Promote, and a Pawn can only promote to Commoner.
+The Knight promotes to Lion, and thus gains unusually much in value.
+</p>
+<h3>The Lion piece</h3>
+<p>
+The Lion can make two moves per turn.
+That means it can also capture two pieces per turn,
+one on the square it moves to (as normal), and one 'en passant' on the transit square.
+It can also capture on the transit square, and move on to an empty square ('hit and run'),
+or capture and move back to where it came from ('shooting' the piece from a distance, as it were).
+Of course it can also capture a single piece in the normal Chess manner.
+In that case the transit square is immaterial.
+</p>
+<p>
+The Lion can make such double moves as two King steps,
+i.e. in all directions, and arbitrarily changing direction between them.
+It can also jump over the transit square, i.e. reach the distant two-step destination in a single jump.
+Finally it can also just make a step to an adjacent square, refraining from taking a second step.
+</p>
+<h3>Restrictions on Lion capture</h3>
+<p>
+There are rules to make Lion trading very difficult, in order to keep the Lions in play.
+Basically they specify that two Lions cannot be captured in consecutive half-moves.
+When the first capture is Lion x Lion from a distance,
+it is forbidden to play it if pseudo-legal (i.e. without taking account of check) recapture of the capturing Lion is possible
+<i>with another piece than King</i>.
+So even when the Lion is protected only with a pinned piece, the other Lion cannot capture it <i>from a distance</i>,
+just like a King could not capture it.
+</p><p>
+When a non-Lion captures a Lion, it is just the other way around:
+then the 'counterstrike' by a non-Lion against the Lion is forbidden.
+One possibility left open is thus when you capture an adjacent Lion.
+But then you would in general be foolish to allow recapture,
+as you could take the Lion hit-and-run fashion, fleeing to a save square.
+An exception to the rule is when a valuable opponent piece (i.e. not a Pawn) forms a 'bridge' between the Lions;
+you may then capture that piece in the first leg of the double-move,
+and then take the opponent Lion with the second leg.
+Then the opponent can recapture, but he will have lost a valuable piece.
+In the late end-game, when you have nothing to protect your Lion with other than King,
+trading becomes possible.
+</p>
+<h3>XBoard interface issues</h3>
+<p>
+This game has to be played with the option Show Target Squares on!
+This option will cause marking of the target squares of any piece you select or grab,
+by the engine (with legality testing off) or by XBoard (legality testing on).
+Moving to a square marked in cyan will be interpreted not as the final destination,
+but as the transit square after the first step of a multi-leg move.
+XBoard will then highlight the possible destination squares of the second leg from there.
+Should you want to end on the cyan square, you click it again, (it will be no longer marked in cyan),
+and XBoard will terminate the move after the first leg.
+You can also move back to the starting square, to 'shoot' the opponent piece from nearby.
+</p>
+<p>
+XBoard will allow both the Chess-like and the Shogi-like promotion;
+the engine will have to decide which promotion style it thinks legal.
+The default choice in 'sweep-promotions' mode will be deferral for pieces, however,
+to facilitate Chess-like play.
+To play a Shogi promotion in this mode you should enter it as a click-click move,
+but during the click on the promotion square move the mouse pointer down until the promoted piece appears, and only then release the mouse button.
+The Pawn will show Queen as default, and a 'dragging click' on the promotion square will cycle through all choices.
+In the Shogi version you would have to choose the Commoner that way.
+With a promotion popup you would have to press 'No' on piece moves into the zone when you play the Chess-like version,
+and press 'Commoner' on Pawn promotions when you play the Shogi-like version.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The board is 10x10, with a 3-rank-deep promotion zone.
+The initial setup leaves an almost empty rank behind the pieces, where you can immediately castle.
+You have a Lion, Crowned Rook, Crowned Bishop and two Soldiers as extra pieces.
+In the Shogi-like version of the rules, some pieces other than Pawn can also promote.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+</p>
+<p>
+With a single Commoner you can force checkmate on a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+A Queen is upward compatible with all weaker pieces except Knight.
+So only promotion to Queen or Knight makes sense,
+(except perhaps for rare situations where you might have to avoid stalemate).

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>There is no initial double-push, and thus no en-passant capture.</li>
+<li>Pawns promote to Ferz when they reach last rank; there is no choice.</li>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) also counts as a loss.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Commoner (Man) replaces the Queen.
+The Ferz and Alfil (Elephant) from Shatranj are added, and the board width expanded to accomodate them.
+The Pawns have no double move.
+There is no castling.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight, Ferz or Wazir (in addition to your own King).
+Two Knights, Ferzes or two Wazirs also cannot do this, and F + W only in rare situations.
+The Commoner can force checkmate against a bare King.
+</p>
+<p>
+Alfils are not only color bound, but also skip over half the files and ranks.
+So they can only reach 8 squares, making them next to worthless.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+<b><li>Pieces captured change color, and are kept in hand by the side who captured them.
+In stead of a normal move, such pieces can be dropped at any later time.</li>
+<li>Pawns can not be dropped on first or last rank.</li>
+<li>Pieces obtained by promotion revert to Pawns on capture.</li>
+</b>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+Pieces obtained by promotions are indicated by slightly modified versions of the conventional piece symbols.
+(E.g. the Rook has a pointy roof, the Knight a blind-fold, etc.)
+If you don't want that, start XBoard with the option <b>-disguisePromoted true</b>.
+You can drop pieces by dragging them onto the board from the holdings displayed beside the board.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+Captured pieces can later be dropped to augment the army of their capturer.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Because pieces are dropped back, there will not be a traditional end-game.
+Trading material does not constitute progress towards winning, even when you are ahead.
+</p>
+<p>
+Because pieces obtained through promotion revert to Pawns on capture,
+they are really different piece types from the primordial pieces that move the same.
+They are in fact more valuable: it is much better to lose a Queen that gives the opponent a Pawn in hand,
+than to lose a Queen that gives him a Queen in hand.

+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li><b>The board wraps around like a cylinder, the h-file connecting to the a-file</b>.</li>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+Cylinder Chess must be played with legality testing off, as XBoard does not understand the wrapping of the board.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The board wraps around as a cylinder.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single <b>Rook</b>,Bishop or Knight (in addition to your own King).
+Two Knights and Bishops in any combination cannot do that either.
+(Because the board has no corners, forcing checkmate has become much more difficult.)
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+The Rook and Knight hardly benefit from the cylinder board.
+The Bishop, whose moves normally often end on the left or right board edge, does benefit some,
+and a Queen gets very dangerous.

+<li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>

+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move <b>three</b> steps in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square next to the King on the other side.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>The Falcon piece</h3>
+<p>
+The Falcon is a so-called multi-path piece.
+It complements the moves of all orthodox pieces, in the sense that it can reaches all squares reachable by King could reach in 3 moves
+that cannot be reached by R, B or N in a single move.
+A King would always need three steps to reach the Falcon destinations,
+(one diagonal and two straight, or two diagonal and one straight),
+but it can always do so in three ways, depending on the order of the straight and diagonal steps.
+The Falcon must follow the path a King could have followed,
+and if all the three paths are blocked, the Falcon cannot move to that destination.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Falcon pieces are extra, and the board is expanded to accomodate them.
+To handle the larger board width, the King moves 3 squares on castling.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King). King + Falcon can force mate on a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+<h3>Differences with FIDE</h3>
+<p>
+Capture is mandatory.
+The King is not special in any way, and can be captured like any other piece.
+Hence the concept of 'check' does not exist.
+Pawns can promote to King.
+</p>
+<h3>Strategy issues</h3>
+<p>
+The King is actually a good choice for a promotion piece, as it is not so easy for the opponent to feed a lot of material to a King.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move <b>three</b> squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square next to the King on the other side.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Chancellor and Archbishop pieces are extra, and the board is expanded to accomodate them.
+To handle the larger board width, the King moves 3 squares on castling.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+The Archbishop can force checkmate against a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As Chancellor and Archbishop are nearly equal in value to Queen, under-promotion is very common,
+and there is virtually never any need to promote to R, B or N.
+</p>
+<p>
+The super-pieces (Q, C, A) devaluate by the presence of lower-valued opponent pieces.
+As a result trading Q for R + B is in general a good trade when you still have both J,
+as the latter gain in value by eliminating the opponent's R and B,
+which is more compensation than the intrinsic value difference between Q and R + B.

+<li>The Promotion zone consists of the last three ranks.</li>
+<li>When arriving on last rank, promotion is mandatory. On other ranks it is optional.</i>
+<li>If no promotion piece is available for a mandatory promotion, the Pawn cannot be advanced.</li>

+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+When a Pawn can be promoted, XBoard first advances it as a Pawn to the promotion square.
+Then it waits for you to complete the move entry by clicking on the piece in the holdings beside the board that you want to promote to.
+To defer promotion you can click on a Pawn or on an empty square in the holdings of the promoting side.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The Chancellor and Archbishop pieces are extra, and the board is expanded to accomodate them.
+There is no castling.
+Promotion only allows you to regain back a piece that you lost before.
+The promotion zone is 3 ranks deep, and promotion is only mandatory on last rank.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+The Archbishop can force checkmate against a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+As a result trading Q for R + B is in not as bad when you still have A and C,
+as the latter gain in value by eliminating the opponent's R and B,
+which is more compensation than the intrinsic value difference between Q and R + B.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>There is no initial double-push, and thus no en-passant capture.</li>
+<li>Pawns promote to a piece chosen from the set of captured pieces, or to Soldier when they reach last rank.
+The chosen piece is then removed from this set.</li>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+<li>If your opponent only has a King at the beginning of your turn, and your king is not yet bare, you win.
+This means that after you capture the last piece, the opponent gets one equalizing turn to recapture yours,
+in which case it would be a draw.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+When a Pawn can be promoted, XBoard first advances it as a Pawn to the promotion square.
+Then it waits for you to complete the move entry by clicking on the piece in the holdings beside the board that you want to promote to.
+Initially there are a number of Soldiers available in the holdings,
+for when you should promote before any of your pieces is captured.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+There are no sliders such as Rook, Bishop or Queen in this game:
+their distant moves have all been replaced by a single two-square jumping move.
+In addition it is more related to Capablanca Chess than to FIDE,
+featuring compounds of Knight and the pieces substituting for Rook and Bishop,
+and the wider board to accomodate them.
+There is no double-push on the Pawns (and thus no e.p. capture),
+and promotion only allows you to regain back a piece that you lost before,
+or one of the stocked Soldier pieces that do not occur in the initial setup.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Elephants are confined to squares of a single color.
+Having Elephants on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As the three strongest pieces (General, Minister and High Priestess) are nearly equal in value, under-promotion is very common.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move <b>to the square neighboring</b> a Rook that has not moved before,
+in which case that Rook is moved to the square next to the King on the other side.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Janus pieces are extra, and the board is expanded to accomodate them.
+The King starts on the other side of the Queen.
+Castling is asymmetric; the King moves 4 steps on long castling, 3 steps on short.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+The Janus can force checkmate against a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As Janus is nearly equal in value to Queen, under-promotion to it is common,
+and there is virtually never any need to promote to R, B or N.
+</p>
+<p>
+The super-pieces (Q, J) devaluate by the presence of lower-valued opponent pieces.
+As a result trading Q for R + B is in general a good trade when you still have both J,
+as the latter gain in value by eliminating the opponent's R and B,
+which is more compensation than the intrinsic value differene between Q and R + B.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A Royal Knight that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square on the other side next to the Royal Knight.
+This is only allowed if all squares traveled through by Royal Knight and Rook are empty (after their removal),
+when the Royal Knight is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your Royal Knight to check.</li>
+<li>The game is won by checkmating the opponent's Royal Knight.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The King moves as a Knight, the Knights move as a King.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single <b>Rook</b>, Bishop or Commoner (in addition to your own King).
+All pairs of pieces can force checkmate on a bare King, however.
+A Queen can even do it without help of its Royal Knight, and is thus extremely dangerous.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+</ul>
+<h3>The Lion piece</h3>
+<p>
+The Lion can make two moves per turn.
+That means it can also capture two pieces per turn,
+one on the square it moves to (as normal), and one 'en passant' on the transit square.
+It can also capture on the transit square, and move on to an empty square ('hit and run'),
+or capture and move back to where it came from ('shooting' the piece from a distance, as it were).
+Of course it can also capture a single piece in the normal Chess manner.
+In that case the transit square is immaterial.
+</p>
+<p>
+The Lion can make such double moves as two King steps,
+i.e. in all directions, and arbitrarily changing direction between them.
+It can also jump over the transit square, i.e. reach the distant two-step destination in a single jump.
+Finally it can also just make a step to an adjacent square, refraining from taking a second step.
+</p>
+<h3>Restrictions on Lion capture</h3>

+There are rules to make Lion trading very difficult, in order to keep the Lions in play.
+Basically they specify that two Lions cannot be captured in consecutive half-moves.
+When the first capture is Lion x Lion from a distance,
+it is forbidden to play it if pseudo-legal (i.e. without taking account of check) recapture of the capturing Lion is possible
+<i>with another piece than King</i>.
+So even when the Lion is protected only with a pinned piece, the other Lion cannot capture it <i>from a distance</i>,
+just like a King could not capture it.
+</p><p>
+When a non-Lion captures a Lion, it is just the other way around:
+then the 'counterstrike' by a non-Lion against the Lion is forbidden.
+One possibility left open is thus when you capture an adjacent Lion.
+But then you would in general be foolish to allow recapture,
+as you could take the Lion hit-and-run fashion, fleeing to a save square.
+An exception to the rule is when a valuable opponent piece (i.e. not a Pawn) forms a 'bridge' between the Lions;
+you may then capture that piece in the first leg of the double-move,
+and then take the opponent Lion with the second leg.
+Then the opponent can recapture, but he will have lost a valuable piece.
+In the late end-game, when you have nothing to protect your Lion with other than King,
+trading becomes possible.
+</p>
+<h3>XBoard interface issues</h3>
+<p>
+This game has to be played with the option Show Target Squares on!
+This option will cause marking of the target squares of any piece you select or grab,
+by the engine (with legality testing off) or by XBoard (legality testing on).
+Moving to a square marked in cyan will be interpreted not as the final destination,
+but as the transit square after the first step of a multi-leg move.
+XBoard will then highlight the possible destination squares of the second leg from there.
+Should you want to end on the cyan square, you click it again, (it will be no longer marked in cyan),
+and XBoard will terminate the move after the first leg.
+You can also move back to the starting square, to 'shoot' the opponent piece from nearby.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+One Knight is replaced by a Lion piece with very special properties.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>Capture is mandatory; if ay capture is possible, you cannot play a non-capture.</li>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by being checkmated or being left with a bare King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+Capture is mandatory.
+You win by being checkmated in stead of checkmating, or by having a bare King.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Initially having more and stronger pieces makes you more likely to win.
+</p>
+<p>
+When the opponent has only King and Pawns left, blocking one of his Pawns (e.g. with Knight or Bishop),
+and then carefully refraining from attacking it while using your powerful pieces to shephard his King
+towards your own Pawns, and then finally sacrificing your mobile material to it,
+is a good way to win.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>There is no initial double-push, and thus no en-passant capture.</li>
+<li>Pawns promote to Met when they reach the <b>6th rank</b>; there is no choice.</li>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Queen and Bishops are replaced by Ferz and Elephant.
+Pawns start on the third rank.
+Promotion happens on 6th rank.
+Promotion always to Met.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Met, Elephant or Knight (in addition to your own King).
+Two Knights or two Mets cannot do it either.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns move <b>and capture</b> straight ahead.</li>
+<li>It is forbidded to have more than one Pawn in the same file.</li>
+<li>It is forbidden to checkmate the opponent with a Pawn drop.</p>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>The game is won by capturing the opponent's King.</li>
+<li>Pieces captured change color, and are kept in hand by the side who captured them.
+In stead of a normal move, such pieces can be dropped at any later time.</li>
+<li>Pieces cannot be moved or dropped to a location where all their moves would go off board.</li>
+<li>Pieces optionally promote at the end of a move into, in or out of the promotion zone.</li>
+<li>The promotion zone consists of the last rank.</li>
+<li>Pieces obtained by promotion revert to their original form on capture.</li>
+<li>Perpetual checking is forbidden, and would be ruled a loss on the 4-fold repeat.</li>
+<li><b>On other 4-fold repetitions white loses.</b></li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+Mini-Shogi is (not yet) a standard variant in XBoard.
+It has to be played in XBoard by selecting regular Shogi
+after having set the board- and holdings-size overrides in the New Variant dialog all to 5
+(i.e. 5x5 board, and holdings for 5 piece types).
+This is not all, however; the pieceToCharTable has to be changed to tell XBoard that the Lance and Knight do not participate.
+(In regular Shogi they would, but here they would push Silver and Gold out of the holdings!)
+This can unfortunately only be done through command-line options.
+</p>
+<p>
+It is therefore best to put all options needed to massage XBoard into playing this variant in a settings file mini.xop.
+On install .xop files are associated with XBoard, so clicking them would start XBoard with the options in that file.
+You could then set everything in the file needed to start in mini-Shogi mode:
+<pre>
+-variant shogi
+-boardHeight 5
+-boardWidth 5
+-holdingsSize 5
+-pieceToCharTable "P.BR.S...G.+.++.+Kp.br.s...g.+.++.+k"
+</pre>
+Since the game is just a subset of regular Shogi, legality testing can remain on.
+You could also specify your favorite mini-Shogi engine with -fcp in that file.
+</p>
+<p>
+You can drop pieces by dragging them onto the board from the holdings displayed beside the board.
+</p>
+<p>
+Of course there will always be people that prefer an oriental look, with pentagonal kanji tiles.
+XBoard comes with a set of kanji pieces in the 'themes/shogi' sub-directory of its data directory
+(e.g. /usr/local/share/games/xboard).
+You can select that as -pieceImageDirectory (-pid for short) from the command line, or from the View -> Board dialog.
+You would also have to tick 'Flip black pieces Shogi style' there (or use the option <b>-flipBlack true</b>)
+to make sure the pieces won't go upside down when you flip the view.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+In stead of Queens you have Silver and Gold Generals.
+Pawns capture straight ahead.
+Captured pieces can later be dropped to augment the army of their capturer.
+There is no castling, Pawn double-push or e.p. capture.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Because pieces are dropped back, there will not be a traditional end-game.
+Trading material does not constitute progress towards winning, even when you are ahead.
+</p>
+<p>
+Because Gold Generals obtained through promotion revert to their original form on capture,
+they are really different piece types from the primordial Golds that move the same.
+In notation they are therefore not indicated as 'G', but as the ID of the original piece prefixed with a '+'.
+Especially the promoted Pawn (aka Tokin) is more valuable: it is much better to lose a Gold that gives the opponent a Pawn in hand,
+than to lose a Gold that gives him a Gold in hand.
+</p>
+<p>
+It is a big advantage to have a General on the central square.
+</p>
+<p>
+Pieces in hand are in general worth more than on the board, as they are much more mobile.
+And you can drop them in the promotion for an easy promotion on the next turn.
+But pieces in hand cannot capture anything, and don't guard your promotion zone.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to any other (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move <b>three</b> squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square next to the King on the other side.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+<li>The Elephant or Hawk can be 'gated' into play, by placing them on a square evacuated by a back-rank piece
+that moved for the first time, as second part of the same turn.</li>
+<li>During gating, your King must not 'pass through check'.</li>
+<li>When castling, you can gate onto the King or Rook square, but not on both.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+To perform a gating move, first select the piece to be gated.
+(When you have not switched off highlighting or the line gap, this will draw a yellow border around the piece.)
+Then move the piece on the back rank.
+If you drag the piece, the gated piece will appear from under it.
+(With click-click moving you will only see it after the move is already done.)
+To gate on the Rook square after castling, you have to enter the castling by dragging the Rook onto the King!
+</p>
+<p>
+To enter a gating move by typing, you have to suffix them with /H or /E.
+For gating on the Rook square after castling, you would have to write the castling as RxK.
+(Ughh! Good thing that no one in his right mind would want to gate there!)
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The Elephant and Hawk pieces are extra, and enter the board by gating.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+The Archbishop can force checkmate against a bare King.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As Elephant and Hawk are nearly equal in value to Queen, under-promotion is very common.
+</p>
+<p>
+The super-pieces (Q, E, H) devaluate by the presence of lower-valued opponent pieces.
+As a result trading Q for R + B is in general a good trade when you still have E and H,
+as the latter gain in value by eliminating the opponent's R and B,
+which is more compensation than the intrinsic value difference between Q and R + B.
+</p>
+<p>
+Keeping E and H in hand is good if there are still many gating opportunities,
+as you can then gate at the location that is most damaging to your opponents position.
+When there are not too many positions left, protecting the remaining ones becomes a vulnerability, however,
+so you better use them were you still can.
+If you still have a piece in hand, and only a single Knight that can gate it (bacause all your other pieces already moved),
+even sacrificing a Queen for that Knight would gain your opponent a piece.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>There is no initial double-push, and thus no en-passant capture.</li>
+<li>Pawns promote to Ferz when they reach last rank; there is no choice.</li>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) also counts as a loss for the stalemated side.</li>
+<li>If your opponent only has a King at the beginning of your turn, and your king is not yet bare, you win.
+This means that after you capture the last piece, the opponent gets one equalizing turn to recapture yours,
+in which case it would be a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The Ferz and Alfil replace the Queen and Bishop.
+The Pawn have no double move.
+No castling.
+The King starts on the e-file.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Because of the baring rule a win is possible with any material other than a bare King.
+</p>
+<p>
+Alfils are not only color bound, but also skip over half the files and ranks.
+So they can only reach 8 squares, making them next to worthless.

+<h1>Sho Shogi (precurser of modern Japanese Chess)</h1>
+<p>
+Sho Shogi means 'small Shogi', and was one of the smaller variants of Japanese Chess,
+living in the shadow of its far more popular big brother, Chu Shogi ('middle Shogi').
+Until people invented piece drops for the captured pieces.
+The small game was much more suitable for playing with piece drops,
+and a small adaptation (eliminating the Elephant) made it into the modern game.
+While Chu Shogi is in fact utterly unsuitable for playing with drops.
+And in the end, the drops won the day!

+<li>It is forbidded to have more than one Pawn in the same file.</li>
+<li>It is forbidden to checkmate the opponent with a Pawn drop.</p>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>The game is won by capturing the opponent's only King.</li>
+<li>Pieces promote at the end of a move into, in or out of the promotion zone.</li>
+<li>The promotion zone consists of the last three ranks.</li>
+<li>Perpetual checking is forbidden, and would be ruled a loss on the 4-fold repeat.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+Sho Shogi is not a standard variant in XBoard.
+It has to be played in XBoard by selecting regular Shogi
+after having set the holdings-size override in the New Variant dialog to 0, to disable piece drops.
+This is not all, however; the pieceToCharTable has to be changed to tell XBoard that the Elephant participates.
+This can unfortunately only be done through command-line options.
+</p>
+<p>
+It is therefore best to put all options needed to massage XBoard into playing this variant in a settings file sho.xop.
+On install .xop files are associated with XBoard, so clicking them would start XBoard with the options in that file.
+You could then set everything in the file needed to start in Sho-Shogi mode:
+<pre>
+-variant shogi
+-holdingsSize 0
+-pieceToCharTable "PNBRLSE..G.+.++.++Kpnbrlse..g.+.++.++k"
+</pre>
+Since the game is just a subset of regular Shogi, legality testing can remain on.
+You could also specify your favorite Sho-Shogi engine with -fcp in that file.
+</p>
+<p>
+Of course there will always be people that prefer an oriental look, with pentagonal kanji tiles.
+XBoard comes with a set of kanji pieces in the 'themes/shogi' sub-directory of its data directory
+(e.g. /usr/local/share/games/xboard).
+You can select that as -pieceImageDirectory (-pid for short) from the command line, or from the View -> Board dialog.
+You would also have to tick 'Flip black pieces Shogi style' there (or use the option <b>-flipBlack true</b>)
+to make sure the pieces won't go upside down when you flip the view.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+In stead of Queens you have Silver and Gold Generals, and Lances.
+The Knight only has the two forward-most moves of a FIDE Knight.
+Pawns capture straight ahead.
+There is no castling, Pawn double-push or e.p. capture.
+Other pieces than Pawns also promote.
+The promotion zone is three ranks deep in stead of one.
+You have an Elphant that can promote to a second King.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Most pieces are quite slow, or not manoeuvrable at all, and their practical value is very dependent on how far they are from the Kings.

+<h1>Shogi (Japanese Chess)</h1>
+<p>
+Shogi (literally meaning 'Generals Game') is highly popular in Japan,
+and is the World's third major Chess variant, after Xiangqi and FIDE.
+Draws hardly occur, because there rule that captured pieces can be dropped back on the board
+ensures the game can go on until a decision is reached.
+Historically, it are these piece drops that have won the game its popularity;
+the dropless version, Sho Shogi (= small Shogi) was overwhelmed in popularity by the also dropless Chu Shogi
+(= middle Shogi).

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns move <b>and capture</b> straight ahead.</li>
+<li>It is forbidded to have more than one Pawn in the same file.</li>
+<li>It is forbidden to checkmate the opponent with a Pawn drop.</p>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>The game is won by capturing the opponent's King.</li>
+<li>Pieces captured change color, and are kept in hand by the side who captured them.
+In stead of a normal move, such pieces can be dropped at any later time.</li>
+<li>Pieces cannot be moved or dropped to a location where all their moves would go off board.</li>
+<li>Pieces promote at the end of a move into, in or out of the promotion zone.</li>
+<li>The promotion zone consists of the last three ranks.</li>
+<li>Pieces obtained by promotion revert to their original form on capture.</li>
+<li>Perpetual checking is forbidden, and would be ruled a loss on the 4-fold repeat.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+You can drop pieces by dragging them onto the board from the holdings displayed beside the board.
+</p>
+<p>
+Of course there will always be people that prefer an oriental look, with pentagonal kanji tiles.
+XBoard comes with a set of kanji pieces in the 'themes/shogi' sub-directory of its data directory
+(e.g. /usr/local/share/games/xboard).
+You can select that as -pieceImageDirectory (-pid for short) from the command line, or from the View -> Board dialog.
+You would also have to tick 'Flip black pieces Shogi style' there (or use the option <b>-flipBlack true</b>)
+to make sure the pieces won't go upside down when you flip the view.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+In stead of Queens you have Silver and Gold Generals, and Lances.
+The Knight only has the two forward-most moves of a FIDE Knight.
+Pawns capture straight ahead.
+Captured pieces can later be dropped to augment the army of their capturer.
+There is no castling, Pawn double-push or e.p. capture.
+Other pieces than Pawns also promote.
+The promotion zone is three ranks deep in stead of one.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Because pieces are dropped back, there will not be a traditional end-game.
+Trading material does not constitute progress towards winning, even when you are ahead.
+</p>
+<p>
+Because Gold Generals obtained through promotion revert to their original form on capture,
+they are really different piece types from the primordial Golds that move the same.
+In notation they are therefore not indicated as 'G', but as the ID of the original piece prefixed with a '+'.
+Especially the promoted Pawn (aka Tokin) is more valuable: it is much better to lose a Gold that gives the opponent a Pawn in hand,
+than to lose a Gold that gives him a Gold in hand.
+</p>
+<p>
+Most pieces are quite slow, or not manoeuvrable at all, and their practical value is very dependent on how far they are from the Kings.
+</p>
+<p>
+Pieces in hand are in general worth more than on the board, as they are much more mobile.
+And you can drop them in the promotion for an easy promotion on the next turn.
+But pieces in hand cannot capture anything, and don't guard your promotion zone.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (Perians straight move, diagonal capture, Spartans the other way around).</li>
+<li>Pawns can move two squares straight ahead from their initial position, in the direction(s) of their non-capture.</li>
+<li>The double-push of Persian Pawns can be blocked, but Hoplites can jump.</li>
+<li>There is no en-passant capture.</li>
+<li>Pawns/Hoplites promote to another piece of their own side when they reach last rank.</li>
+<li>Hoplites can promote to King, but only when the Spartans have a single King just before the promotion.</li>
+<li>Persian Pawns can not promote to King.</li>
+
+</ul>
+<h3>Castling</h3>
+<p>
+The Persian King, if it has not moved before, can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose <b>all</b> your Kings to capture <b>at the same time</b>.</li>
+<li>The Spartans can leave one of their Kings under attack, and as a consequence, have it captured.</li>
+<li>The game is won by checkmating the opponent's King or King-pair.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Duple check</h3>
+<p>
+The rule that the Spartans cannot leave both Kings attacked would <b>not</b> follow from a rule where you lose when all your Kings are captured.
+Because under that rule the opponent could at most capture one of the two in the next turn,
+and the next turn the other King could move to safety.
+So it is an special rule that leaving them both under attack is illegal, (and only then are you considered to be in check).
+In consequence that when you cannot get out of that check situation, you are (duple) checkmated.
+(It is as if at the begining of every turn you can decide anew which of your Kings is the royal one.)
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The black army is completely different.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop, Knight or Lieutenant (in addition to your own King).
+Two Knights cannot do that either.
+</p>
+<p>
+Although Captains are worth less than orthodox minors B and N, they can force checkmate on a bare King.
+As a result the Spartans can often win when they are a minor ahead, if one of their minors is a Captain
+(e.g. KLCKB is a win, where KBNKB in FIDE is a draw).
+</p>
+<p>
+A pair of Spartan Kings also can force checkmate against a bare King.
+Furthermore, Kings are tough defenders, because they cannot be attacked by the opponent's King.
+So if all the attacker's power is in a single piece, the defending King pair has nothing to fear when they protect each other.
+This makes even KQKK is a draw (provided the Spartan kings can connect).
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+Because Hoplites can choose their path, they become passers very easily.
+This is only of limited value, though, as moving them around an obstructing Persian Pawn usually also gives the latter a free path to promotion.
+Hoplites do stay on the same color when they do not capture.
+A Bishop on the other color is thus powerless to stop their promotion.

+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,

+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>Capture is mandatory; if ay capture is possible, you cannot play a non-capture.</li>
+<li>The game is won by the side that has no legal moves (usually because he has no pieces left).</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The King is not special in any way, and can be captured like any other piece.
+Hence the concept of 'check' does not exist.
+Pawns can promote to King.
+</p>
+<h3>Strategy issues</h3>
+<p>
+The King is actually a good choice for a promotion piece, as it is not so easy for the opponent to feed a lot of material to a King.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to a piece chosen from the set of captured or substituted pieces when they reach last rank.
+The chosen piece is then removed from this set.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>XBoard interface issues</h3>
+<p>
+When a Pawn can be promoted, XBoard first advances it as a Pawn to the promotion square.
+Then it waits for you to complete the move entry by clicking on the piece in the holdings beside the board that you want to promote to.
+You can use the New Shuffle dialog to control the randomization of the initial position.
+</p>
+<h3>Differences with FIDE</h3>
+<p>
+The start position contains four unorthodox pieces.
+Promotion only to pieces that were captured before (or substituted).
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+An e-file King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed if all squares between King and Rook are empty,
+when the King is not in check on the square it came from,
+and would not be in check on any of the squares it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>The King closest to square a1 is the royal one (horizontal measure prevailing over vertical).</li>
+<li>It is not allowed to expose your <b>royal</b> King to capture ('check').</li>
+<li>The game is won by checkmating the opponent (i.e. being in check, and not being able to get out of it).</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+You have a pair of Kings, and only a single Bishop.
+Only one of the Kings is royal, but which one can change during the game, as it depends on their relative location on the board.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+Two Knights cannot do that either.
+Two Kings can force checkmate on a bare King.
+</p>
+Your non-royal King can be exposed to capture, and thus captured.
+After that, the remaining King will always be royal.
+<p>
+</p>
+Once both sides are down to a single King, this variant degenerate to orthodox Chess.
+<p>
+</p>
+The spare King is a tough defender, because it cannot be attacked by the opponent's royal King.
+So if all the attacker's power is in a single piece, the defending King pair has little to fear when they protect each other.
+This makes even KQKK is a draw (provided the Kings can connect).

+<h1>Wild Castle</h1>
+<p>
+This is a shuffle variant of normal Chess, which preserves the possibility to do sort of conventional castling,
+by starting Rooks always in he corner, and the King on the central files.
+When played on an Internet Chess Server, the King can also start on the d-file, and you can castle from there.
+This adds nothing to the game, though, it just produces mirror images of other start positions.
+So in local mode XBoard does not bother to do this.

+<h1>Xiangqi (Chinese Chess)</h1>
+<p>
+Xiangqi is the World's number one Chess variant in terms of number of players.
+Almost all players live in China, Taiwan or Vietnam, though.
+It is a fast and aggressive game, often described as a 'race to mate'.
+When it gets to an end-game it is often a draw,
+because there are many pieces that cannot leave their own board half,
+and thus can be used to defend but not to attack or to trade for the opponent's defenders.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture and move straight ahead.</li>
+<li>When they reach the opponent's board half ('cross the River'), they can also move and capture sideways.</li>
+<li>There is no real promotion; when Pawns reach last rank they are stuck there.</li>
+</ul>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>Kings are not allowed to face each other, i.e. be on the same file with nothing in between.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a los for the stalemated side.</li>
+<li>Perpetual checking is forbidden, and the side that checks is ruled to lose on the 3rd repeat.</li>
+<li>When both sides are perpetually checking each other, the game is ruled a draw, however.</li>
+<li>It is also forbidden to perpetually harass the same piece other than King (see below).</li>
+<li>But when both sides do it, the game is again ruled a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+The board is sub-divided into zones, and some pieces are not allowed to cross some zone boundaries.
+Pieces move in general different than their FIDE counterpart. Only the Rook moves truly the same.
+</p>
+<h3>Perpetual Chasing</h3>
+<p>
+It is forbidden to perpetually harass the same piece,
+and when a repeat loop (after 3 repeats) has one side violating this rule, that side will forfeit the game.
+This is only invoked if there wasn't any perpetual checking in the loop as well.
+Exact rules for this are quite complex.
+Basically, when a repeat loop creates a <i>new</i> attack on the same <i>unprotected</i> piece on <i>every</i> move,
+the move sequence will be considered a perpetual chase.
+The chasing side then is ruled to lose, but if both sides are chasing, it is a draw.
+A Rook counts as unprotected against attacks of C or H.
+On the other hand, being able to capture your attacker (as when equal pieces attack each other) counts as (pre-emptive) protection.
+Attacks on a Pawn that is still on its own board half, or attacks by a King are never considered chases.
+</p>
+<p>
+Only legal moves should be taken into account; i.e. pinned pieces are not considered attackers or protectors.
+An attack by the same piece is not considered a new one just because the attacking piece moved to another location,
+e.g. when a Rook moves along the ray of the attack.
+Note that the above rules do not take into account whether the attacking or protecting captures are good or non-sensical,
+or if pieces are <i>sufficiently</i> protected against multiple attacks.
+Even if recapturing would get you mated in one, the piece would still count as protected!
+Also note that is perfectly allowed to alternately chase different pieces.
+Even if one of the pieces is a King.
+</p>
+<h3>Strategy issues</h3>
+<p>
+Any piece except a Pawn on the last rank can force Checkmate against a bare King.

+<title>Variants supported by XBoard</title>
+</header>
+<body>
+<img src="../winboardF.jpg">
+<h1>Chess variants supported by XBoard</h1>
+<p>
+Next to orthodox Chess (aka FIDE or Mad Queen), XBoard supports many other Chess variants.
+This includes the World's major forms of Chess: Chinese, FIDE, Japanese, and Thai Chess.
+But also many popular western variants (Suicide Chess, Crazyhouse, Chess960, Gothic/Capablanca Chess, Seirawan Chess).
+</p>
+<p>
+Full support by XBoard means that the latter is fully aware of how all pieces move, and what the winning condition is.
+This means the variant can be played with the option Test Legality switched on,
+and that it can accurately check any result claims that engines make.
+Non-supported variants can often be played with legality checking switched off.
+Then any of the 22 piece types known by XBoard can be used in ways XBoard does not expect.
+The only real drawback of this is that the game notation looks a bit crummy,
+with many spurious or missing disambiguators, check and checkmate symbols.
+XBoard will always be able to read suh games back, however (as on reading it suffers from the same misconceptions on piece movement).
+This can be kept baerable by choosing XBoard supported pieces to represent the unsupported ones that
+move as similar as possible.
+</p>
+<p>
+Some variants are only partially supported.
+This means they have to be played with legality checking off,
+although XBoard knows they exist, and even implements some of their rules that no other variant would allow.
+For instance, in Berolina Chess Pawns move diagonally, and in any other variant this would lead to disappearence
+of other Pawns during the game, as normally XBoard interprets a diagonal Pawn move to an empty square as e.p. capture.
+</p>
+<p>
+The following list tries to group all variants by properties.
+Some duplicates occur when a variant fits in more than one group.

+<h3>Pawn peculiarities</h3>
+<ul>
+<li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
+<li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>
+<li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
+as if they had only moved 1 square ahead.</li>
+<li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
+</ul>
+<h3>Castling</h3>
+<p>
+A King that has not moved before can move two squares in the direction of a Rook that has not moved before,
+in which case that Rook is moved to the square the King skipped over.
+This is only allowed when the King is not in check, on the square it came from and would not be in check on the square it skipped over.
+</p>
+<h3>General rules</h3>
+<ul>
+<li>It is not allowed to expose your King to check.</li>
+<li>The game is won by checkmating the opponent's King.</li>
+<li>Stalemate (no legal moves, but not in check) is a draw.</li>
+</ul>
+<h3>Differences with FIDE</h3>
+<p>
+None.
+</p>
+<h3>Strategy issues</h3>
+<p>
+It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
+</p>
+<p>
+Bishops are confined to squares of a single color.
+Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
+</p>
+<p>
+As Chancellor and Queen are nearly equal in value to Queen, under-promotion is very common.
