-This section describes how to run the "xshogi" program.
-
-
-<P>
-SYNOPSIS
-
-
-<P>
-xshogi [ options ]
-
-
-<P>
-DESCRIPTION
-
-
-<P>
-xshogi provides an X11/Xt/Athena Widgets user interface for gnushogi.
-With xshogi you can play gnushogi, set up arbitrary positions, force
-variations, or watch xshogi manage a game between two shogi programs.
-Furthermore, it can be used as an interface between two players on
-different displays.
-
-
-<P>
-xshogi can also be used as a shogi board to play out games. It will
-read through a game file or allow a player to play through a variation
-manually (force mode). This is useful for keeping track of email postal
-games or browsing games off the net.
-
-
-<P>
-After starting xshogi, you can make moves by pressing mouse button 1
-while the cursor is over a square with your piece on it and dragging the
-mouse to another square. If the move is illegal, gnushogi will not
-allow it. xshogi will then retract the move.
-
-
-<P>
-COMMAND-LINE OPTIONS
-
-
-<P>
-The following command line options also correspond to X resources that
-you can set in your .Xdefaults file.
-
-
-<DL COMPACT>
-
-<DT><SAMP>`[standard Xt options]'</SAMP>
-<DD>
-xshogi accepts standard Xt options like -display, -geometry, and
--iconic.
-
-<DT><SAMP>`-tc or -timeControl minutes[:seconds]'</SAMP>
-<DD>
-Amount of time for a set of moves determined by movesPerSession. If
-this number of moves is played within the time control period, xshogi
-resets the time clocks. Default: 5 minutes.
-
-<DT><SAMP>`-mps or -movesPerSession moves'</SAMP>
-<DD>
-Number of moves in a time control period. Default: 40 moves.
-
-<DT><SAMP>`-st or -searchTime minutes[:seconds]'</SAMP>
-<DD>
-Tell gnushogi to spend at most the given amount of time searching for
-each of its moves. Without this option, gnushogi chooses its search
-time based on the number of moves and amount of time remaining until the
-next time control. Setting this option also sets -clockMode to False.
-
-<DT><SAMP>`-sd or -searchDepth number'</SAMP>
-<DD>
-Tell gnushogi to look ahead at most the given number of moves when
-searching for a move to make. Without this option, gnushogi chooses
-its search depth based on the number of moves and amount of time
-remaining until the next time control. Setting this option also sets
--clockMode to False.
-
-<DT><SAMP>`-clock or -clockMode (True | False)'</SAMP>
-<DD>
-Determines whether or not to use the clock. If clockMode is False, the
-clock does not run, but the side that is to play next is still
-highlighted.
-
-<DT><SAMP>`-td or -timeDelay seconds'</SAMP>
-<DD>
-Time delay between moves during "Load Game". This doesn't have to be
-a round number. Try -td 0.4. Default: 1 second.
-
-<DT><SAMP>`-nsp or -noShogiProgram (True | False)'</SAMP>
-<DD>
-If this option is True, xshogi acts as a passive shogi board; it does
-not try to start a shogi program, not even to check whether moves made
-in Force mode are legal. It also sets -clockMode to False. Default:
-False.
-
-<DT><SAMP>`-fsp or -firstShogiProgram program'</SAMP>
-<DD>
-Name of first shogi program. In matches between two machines, this
-program plays white. Default: "gnushogi".
-
-<DT><SAMP>`-ssp or -secondShogiProgram program'</SAMP>
-<DD>
-Name of second shogi program, if needed. In matches between two
-machines, this program plays black; otherwise it is not started.
-Default: "gnushogi".
-
-<DT><SAMP>`-fh or -firstHost host'</SAMP>
-<DD>
-Name of host the first shogi program plays on. Default: "localhost".
-
-<DT><SAMP>`-sh or -secondHost host'</SAMP>
-<DD>
-Name of host the second shogi program plays on. Default: "localhost".
-
-<DT><SAMP>`-rsh or -remoteShell shell_name'</SAMP>
-<DD>
-Some systems do not use rsh as the remote shell. This option allows a
-user to name the remote shell command. This should be done in the
-resource file.
-
-<DT><SAMP>`-mm or -matchMode (False | Init | Position | Opening)'</SAMP>
-<DD>
-Automatically run a game between firstShogiProgram and
-secondShogiProgram. If matchMode is set to Init, xshogi will start the
-game with the initial shogi position. If matchMode is set to Position,
-xshogi will start the game with the position specified by the
-loadPositionFile resource. If matchMode is set to Opening, xshogi will
-play out the opening moves specified by the -loadGameFile resource. If
-the -saveGameFile resource is set, a move record for the match will be
-saved in the specified file. Default: "False".
-
-<DT><SAMP>`-lgf or -loadGameFile file'</SAMP>
-<DD>
-Name of file to read a game record from. Game files are found in the
-directory named by the SHOGIDIR environment variable. If this variable
-is not set, the current directory is used unless the file name starts
-with a /.
-
-<DT><SAMP>`-lpf or -loadPositionFile file'</SAMP>
-<DD>
-Name of file to read a game position from. Position files are found in
-the directory named by the SHOGIDIR environment variable. If this
-variable is not set, the current directory is used unless the file name
-starts with a /.
-
-<DT><SAMP>`-sgf or -saveGameFile file'</SAMP>
-<DD>
-Name of file to save a game record to. Game files are saved in the
-directory named by the SHOGIDIR environment variable. If this variable
-is not set, the current directory is used unless the file name starts
-with a /.
-
-<DT><SAMP>`-spf or -savePositionFile file'</SAMP>
-<DD>
-Name of file to save a game position to. Position files are saved in
-the directory named by the SHOGIDIR environment variable. If this
-variable is not set, the current directory is used unless the file name
-starts with a /.
-
-<DT><SAMP>`-coords or -showCoords (True | False)'</SAMP>
-<DD>
-If this option is True, xshogi displays algebraic coordinates along the
-board's left and bottom edges. The default is False. The coordFont
-resource specifies what font to use.
-
-<DT><SAMP>`-mono or -monoMode (True | False)'</SAMP>
-<DD>
-Determines whether xshogi displays its pieces and squares with two
-colors or four. You shouldn't have to specify monochrome. xshogi will
-determine if this is necessary.
-
-<DT><SAMP>`-wpc or -blackPieceColor color'</SAMP>
-<DD>
-Color specification for black pieces suitable for XParseColor(3X11).
-Default: #FFFFCC. These colors look good on a DEC workstation. If you
-need different colors, try using the xcolors application. Source for
-xcolors can be found in the X11 contrib directory.
-
-<DT><SAMP>`-bpc or -whitePieceColor color'</SAMP>
-<DD>
-Same for white pieces. Default: #202020.
-
-<DT><SAMP>`-lsc or -lightSquareColor color'</SAMP>

-OTHER X RESOURCES
-
-
-<DL COMPACT>
-
-<DT><SAMP>`initString'</SAMP>
-<DD>
-The actual string that is sent to initialize the shogi program can be
-set from .Xdefaults. It can't be set from the command line because of
-syntax problems. The default value is "new\nbeep\nrandom\neasy\n".
-The "new" and "beep" commands are required. You can remove the
-"random" command if you like; including it causes gnushogi to
-randomize its move selection slightly so that it doesn't play the same
-moves in every game. Even without "random", gnushogi randomizes its
-choice of moves from its opening book. You can also remove "easy" if
-you like; including it toggles easy mode off, causing gnushogi to think
-on your time. That is, if "easy" is included in the initString, GNU
-Shogi thinks on your time; if not, it does not. (Yes, this does seem
-backwards, doesn't it.) You can also try adding other commands to the
-initString; see the gnushogi documentation (see section <A HREF="gnushogi_17.html#SEC20">gnushogi</A>) for
-details.
-
-<DT><SAMP>`blackString and whiteString'</SAMP>
-<DD>
-These resources control what is sent when the Machine Black and Machine
-White buttons are selected. This is mostly for compatibility with
-obsolete versions of gnushogi.
-
-Alternate bitmaps for piece icons can be specified either by choosing
-one of the built-in sets or with the file name resources described
-above. There are three built-in sets of piece bitmaps available, large
-(the default), medium, or small. It is easiest to select the set you
-prefer in the .Xdefaults file:
-
- XShogi*boardSize: Medium
-
-The font used for button labels and comments can be changed in the
-.Xdefaults file. You may want to choose a smaller font if you are using
-the small pieces:
-
- XShogi*font: helvetica_oblique12
-
-The font used for coordinates (when the showCoords option is True) can
-be set similarly:
-
- XShogi*coordFont: helvetica_10
-
-If you are using a grayscale monitor, try setting the colors to:
-
- XShogi*blackPieceColor: gray100 <BR>
- XShogi*whitePieceColor: gray0 <BR>
- XShogi*lightSquareColor: gray60 <BR>
- XShogi*darkSquareColor: gray40

-asks for a filename. Game files are found in the directory named by the
-SHOGIDIR environment variable. If this variable is not declared then
-the current directory is used unless the file name starts with a /. G
-or g is a keyboard equivalent. The game file parser will accept almost
-any file that contains moves in algebraic notation. If the first line
-begins with `#', it is assumed to be a title and is displayed. Text
-enclosed in parentheses or square brackets is assumed to be commentary
-and is displayed in a pop-up window. Any other text in the file is
-ignored.
-
-<DT><SAMP>`Load Position'</SAMP>
-<DD>
-sets up a position from a position file. If no file is specified a
-popup dialog asks for a filename. Position files are found in the

-starts with a /. Position files must be in the format that the Save
-Position command writes.
-
-<DT><SAMP>`Save Game'</SAMP>
-<DD>
-saves a game to a record file. If no file is specified a popup dialog
-asks for a filename. If the filename exists, the user is asked whether
-the current game record is be appended to this file or if the file

+<H2> 2.5 Differences between shogi and chess </H2>
+<!--docid::SEC18::-->
<P>
-LIMITATIONS
+Some differences between shogi and international chess have been
+mentioned elsewhere in this document; I summarize them here for people
+who are interested in game comparisons. I won't try to deal with the
+thorny question of which game is "better" although my bias may have
+already come through :-) In fact, the drop rule makes the two games so
+different in character that arguing over which game is better is like
+comparing apples to oranges (you'd be better off comparing chess to Chu
+shogi (see section <A HREF="gnushogi_17.html#SEC17">2.4 Shogi variants</A>). However, I believe that if you are a
+chess fan you'll really like shogi as well, and shogi is also popular
+with many people who don't particularly like chess.
+</P><P>
-<P>
-If you press the Pause button during GNU Shogi's turn,
-xshogi will stop the clocks, but gnushogi will still make a
-move.
+Here are the significant differences between chess and shogi:
+</P><P>
+<OL>
+<LI>
+In shogi, captured pieces become the property of the capturer and can
+re-enter play by being dropped onto almost any vacant square. In chess,
+captured pieces are out of the game. Thus, in shogi, piece exchanges
+complicate the play significantly while in chess they simplify it.
<P>
-After a mate or draw when playing against gnushogi, if you
-back up with the Backward button, the clocks are reset
-(because gnushogi has exited and must be restarted).
-
+<LI>
+The shogi board is 9x9; the chess board is 8x8.
<P>
-The game parser recognizes only algebraic notation.
-
-
-<P>
-AUTHORS
-
+<LI>
+Shogi has five pieces with no counterpart in chess: the gold and silver
+generals, the lance, the promoted rook and the promoted bishop. Chess
+has one piece with no counterpart in shogi: the queen. The knight's
+move in shogi is much more restrictive than in chess. Pieces in shogi
+generally have a much smaller range of movement than in chess (unless
+they are in hand).
<P>
-Original authors of XBoard: Chris Sears and Dan Sears.
-
+<LI>
+In shogi, all pieces except the gold general and the king can promote,
+but only to one kind of piece. Promotion is easier in shogi because the
+promotion zone is closer to the starting position of the pieces
+(especially pawns). In chess, only the pawn can promote, but it can
+promote to any other piece except the king.
<P>
-Enhancements for XBoard (Version 2.0): Tim Mann.
-
+<LI>
+In shogi, pawns capture the same way they move. There is no initial
+two-space pawn move and hence no <EM>en-passant</EM> captures. In chess,
+pawns capture diagonally which means that opposing pawns can block each
+other.
<P>
-Conversion to XShogi (Version 1.1): Matthias Mutz.
-
+<LI>
+In shogi, you only have one rook and one bishop. Note that the bishop
+is not restricted to only one "color" square (squares in shogi aren't
+colored, but never mind) because promoted bishops can also move one
+square orthogonally.
<P>
-Current maintainer: Mike Vanier.
-
+<LI>
+There is no special castling move in shogi. The term "castle" is
+used in shogi to denote a defensive formation consisting of (usually)
+three generals which protect the king. There are many such castles
+(about 40 or so have names). See section <A HREF="gnushogi_15.html#SEC15">2.2 Sample game</A>.
<P>
-COPYRIGHT INFORMATION
-
+<LI>
+Draws are much rarer in shogi than in chess. Perpetual check is not
+allowed. Stalemate is a virtual impossibility, and is a loss for the
+stalematee.
<P>
-XShogi borrows its piece bitmaps from CRANES Shogi.
-
+<LI>
+Since pieces are never out of play in shogi, chess-type endgames
+involving only a few pieces do not occur.

-SOFTWARE.
+The effects of all these differences on play include (in my opinion):
+</P><P>
+<OL>
+<LI>
+Piece/pawn structures in chess are more rigid than in shogi. Pawns
+block each other and pawns, once advanced, cannot ever retreat. In
+shogi, you can repair the hole caused by a pawn advance by exchanging
+the pawn and dropping it back where you want it. Thus shogi is more
+fluid than chess and less "structural".
<P>
-The following terms apply to the enhanced version of XShogi distributed
-by the Free Software Foundation:
-
+<LI>
+Counterattack is MUCH more common in shogi than in chess. Games
+typically end in mutual mating attacks, where each player is trying to
+checkmate the other player before being checkmated himself. This makes
+tempo incredibly important and also makes sacrificial play quite common.
<P>
-This file is part of XSHOGI.
-
+<LI>
+Attacks involving only ranging pieces are more a feature of chess than
+of shogi. A shogi attack typically uses a ranging piece or pieces to
+support an attack by short-range pieces (especially generals). It is
+very rare to mate a king with a non-adjacent ranging piece in shogi
+since the player whose king is threatened can almost always interpose by
+dropping a piece.
