Make too-long game non-fatal
GameEnds is now called when the maximum number of moves is exceeded,
rather than DisplayFatalError. Not sure if this properly terminates the

exiting, so that in an unattended automatically running tourney there
was not much fatal, and the entire tourney would in fact be finished.

Fix LoadGameOrPosition starting up engine
When LoadGameOrPosition() is called from NextMatchGame(), the Reset() that

Auto-popup ICS Input Box
Typing to the board made the move type-in pop up, but in ICS mode

Fix display state after failed analysis attempt
When an engine responded to the "analyze" command with an "unknown command"
message, a Reset was done without altering the display, causing a
discrepancy between display and internal state, which caused confusion
when it finally corrected itself. I replaced the Reset call by an
EditGameEvent call, to preserve the loaded game. The Reset was presumably
used to allow for the case where the engine would be so upset by the
analyze command that it needed to be reset by a "new" command, but this
seems overly paranoic for an engine that just recognized the command
as an unknown one.

Add key bindings for loading next/previous game of list

To make them useful, focus has to be transferred to the board widget

seems to get focus rather than the board, which is bad as it is not

H.G. Muller [Tue, 2 Aug 2011 20:58:34 +0000]
Implement searching games in Game List for a position
For this it was needed to reconstruct all positions of the games
without loading them, so they could be compared to the currently
displayed position. A new routine GameContainsPosition is made for that.
In Disambiguate, when the global quickFlag is set, we now do the
disambiguation ignoring check,and only if this leads to an ambiguous
move, we repeat it taking check into account to see if that resolves
the ambiguity. This causes us to miss if unambiguous moves are illegal
because they put their King in check, but who cares?
We now do not make game-list line when not needed. If we do not filter
by text, but by position, there is no need for preparing the game-list
line for games that are not selected. All for efficiency.
H.G. Muller [Thu, 28 Jul 2011 18:47:35 +0000]
Allow entry of variations in PlayFromGameFile mode
Adding variations is more like editing a comment,and not really editing
the game. Therefore we allow it on loaded games. As soon as we are in a
variation, we temporarily switch to a (hidden) EditGame mode, restoring
the original mode when we revert to the main line.
We now also stay in PlayFromGameFile mode after loading a game,
And opening variation (fromtheComment window) in PlayFromGameFile mode
is also allowed.
H.G. Muller [Wed, 27 Jul 2011 16:47:45 +0000]
Force Move History refresh after loading/reverting variation
The Move History window was not refreshed after switching to or from
a variation if that variation happened to have the same length as
the main line. Now a change in storedGames since the previous refresh will
force a full refresh to avoid this. For this to work, storedGames
did have to be decremented after ToNrEvent in PopInner, because ToNrEvent
calls HistorySet before the history is restored, so we don't want
it to snatch away the full refresh. A call to HistorySet had to be
added after PopInner is done restoring the move history.

H.G. Muller [Wed, 19 Jan 2011 10:46:41 +0000]
Allow null move in analysis and edit-game mode
In some games it is allowed to pass your turn. The internal
representation picked for such a null move is the drop of an empty
square, (EmptySquare,DROP_RANK,0,0). Computer-algebraic form is "@@@@",
SAN form is "--", (for compatibility with ChessBase / SCID), and the
non-compliant forms "null", "pass"and "Z0" are recognized in
the parser as well. ApplyMove() has to test for this special case
(to not actually clear a1), and a way to enter the pass for the user had
to be found (clicking the opponent clock, like in EditPosition mode).
The null move is made move irreversible to prevent repetition draws
spanning null moves being adjudicated.
Such entry of null move is now allowed in AnalyzeMode and EditGame mode.
Because Chess engines will not accept null moves, SendMoveToProgram had
to be adapted to send not the move, but the position after it in
case of a null move. This erases the move history in the engine,
so it will not react to 'undo' for that null move, so BackwardInner
had to be adapted to test for intervening null moves, and if one is
found, approach the target from the other side after loading the
earliest position before it not crossing another null move, and
then loading the moves upto the target.
XBoard clock clicks had to be fixed, to pay attention to the shift key.

Give WinBoard Game List its own font
The font fort he Game List used to be shared with the Engine Output and

the font for the Game List(and save it in the settings file), while a
control for it is added in the fonts dialog.

Print reversible plies done in stead of plies to go
Printing the number of plies left to the draw-adjudication point was
confusing when the N-move rule was set to a non-standard value.

move, so the user can compare it to both the engine claim point (100)

Let -sweepPromotions also work for click-click moves
A click-click promotion no longer causes auto-queening, but the down-click
on the to-square causes a Queen to stick to the mouse pointer, and then
allows the user to change it through dragging backwards before releasing it
with an up-click.
In WinBoard this required a slight change in DragPieceBegin, because
the dragged piece there only was made visible when the mouse pointer
actually started moving (and dragInfo.pos was set), presumably under the
assumption that before mouse move the piece was already on the clicked
square. Which in the case of a to-square was of course not true. (Because
a piece jumps to the mouse pointer when the click is not centered on a
square, this gives less jittery static clicks.) So DragPieceBegin has
been given an extra argument now, to indicate whether it should attach
the piece to the mouse pointer immediately.
To make the click-click sweepPromotions work in Shogi (for which the
drag-drop sweepPromotions could never work, because it is not clear the
piece has a posibility to promote when you pick it up), translation of
the sweep-selected piece to a Shogi promoChar had to e added.

Implement Grand Chess
Grand Chess requires a lot of exceptional handling similar to Superchess
and Great Shatran, because it also allows only promotion to a captured
piece. In addition it shares the enlarged promotion zone with Makruk and
Shogi, as well as the fact that promotion can be deferred. The 10-rank
board furthermore required a better generalization of double-pushes and
e.p. captures. On such a board double puhes are now allowed from 2nd and
3rd rank, e.p. capture from 5th and 4th.

Allow promotion to Pawn with legality testing off
In stead of ImpossibleMove promotionto Pawn now merely is an
IllegalMove, so it can be played with legality testing off.

Allow double-digit rank numbers
The parser already understood double-digit numbers on input, and
CoordsToAlgebraic produced them on otput. This patch also fixes sending
of the moves to the computer, for which the moveList was used. The latter
stored 10 as ':', etc,to always get a 4-char move, the characters of which
were frequently being converted to fromY or toY by adding/subtracting ONE.
To not break that the one-character encoding of rank number is kept in
moveList, but in SendMoveToProgram, characters > '9' are converted to
double digits.

Increase efficiency of SAN generation / disambiguation
**************** Risky patch! **********************
The algorithm used for disambiguating and generating SAN was extremely
inefficient, because it generated all pseudo-legal moves from the relevant
position, and then for each of those did a check test (involving generation
of all moves of the opponent), before determining if the move matched the
(proposed or given) SAN move. While it is pointless to generate moves
with a piece that does not match (let alone checking them for legality).
And for a piece that matches, it is pointless to test legality of moves
that do not match the to-square.
To speed up the process GenLegal and GenPseudoLegal have been equiped
with an argument that can indicate the piece type of the required move,
so they can skip generating moves with other pieces. TestLegality,
Disambiguate and CoordsToAlgebraic make use of this facility, and set also
(through global variables rFilter and fFilter) a to-square filter to be
applied in the GenLegalCallback before it tests the move for legality.
This patch is especially tricky for Crazyhouse, where the piece indicated
in the move might not be the piece actually on the board, because the latter
is a promoted Pawn, and has to be demoted toits base type before the
comparison.

Fix compile errors WinBoard
The patch to make non-existing options non-fatal broke WinBoard. All calls
to ExitArgError from it now supply a third argument TRUE to fix it.

Add -fSAN / -sSAN options
These options force the PV of the applicable engine to be converted to SAN.
They make use of the existing ParsePV routine, after shelfing a possible
PV (from user PV walking) to free the space after the last move.
Could be costly in terms of CPU usage.
