-game. The <kbd>r</kbd> key is a keyboard equivalent. In Internet Chess
-Server mode, clears the current state of XBoard, then
-resynchronizes with the ICS by sending a refresh command. If you want to
-stop playing, observing, or examining an ICS game, use an
-appropriate command from the Action menu, not ‘<samp><span class="samp">New Game</span></samp>’.
-See <a href="#Action-Menu">Action Menu</a>.
-<br><dt>New Shuffle Game<dd><a name="index-New-Shuffle-Game_002c-Menu-Item-7"></a>Similar to ‘<samp><span class="samp">New Game</span></samp>’, but allows you to specify a particular initial position
-(according to a standardized numbering system)
-in chess variants which use randomized opening positions (e.g. Chess960).
-The selected opening position will persistently be chosen on any following
-New Game command until you use this menu to select another. Selecting
-position number -1 will produce a newly randomized position on any new game.
-Using this menu item in variants that normally do not shuffle their opening position
-does cause these variants to become shuffle variants until you use the
-‘<samp><span class="samp">New Shuffle Game</span></samp>’ menu to explicitly switch the randomization off,
-or select a new variant.
-<br><dt>New Variant<dd><a name="index-New-variant_002c-Menu-Item-8"></a>Allows you to select a new chess variant in non-ICS mode.
-(In ICS play, the ICS is responsible for deciding which variant will be played,
-and XBoard adapts autmatically.) If you play with an engine, the engine must
-be able to play the selected variant, or the command will be ignored.
-XBoard supports all major variants, such as xiangqi, shogi, chess, chess960,
-Capablanca Chess, shatranj, crazyhous, bughouse.
-<br><dt>Load Game<dd><a name="index-Load-Game_002c-Menu-Item-9"></a>Plays a game from a record file. The <kbd>g</kbd> key is a keyboard equivalent.
-A popup dialog prompts you for the file name. If the file contains more
-than one game, a second popup dialog
-displays a list of games (with information drawn from their PGN tags, if
-any), and you can select the one you want. Alternatively, you can load the
-Nth game in the file directly, by typing the number <kbd>N</kbd> after the
-file name, separated by a space.
-
- <p>The game file parser will accept PGN (portable game notation),
-or in fact almost any file that contains moves in algebraic
-notation.
-Notation of the form ‘<samp><span class="samp">P@f7</span></samp>’
-is accepted for piece-drops in bughouse games;
-this is a nonstandard extension to PGN.
-If the file includes a PGN position (FEN tag), or an old-style
-XBoard position diagram bracketed by ‘<samp><span class="samp">[--</span></samp>’ and ‘<samp><span class="samp">--]</span></samp>’
-before the first move, the game starts from that position. Text
-enclosed in parentheses, square brackets, or curly braces is assumed to
-be commentary and is displayed in a pop-up window. Any other
-text in the file is ignored. PGN variations (enclosed in
-parentheses) are treated as comments; XBoard is not able to walk
-variation trees.
-The nonstandard PGN tag [Variant "varname"] functions similarly to
-the -variant command-line option (see below), allowing games in certain chess
-variants to be loaded. There is also a heuristic to
-recognize chess variants from the Event tag, by looking for the strings
-that the Internet Chess Servers put there when saving variant ("wild") games.

-A popup dialog
-prompts you for the file name. If the game did not begin with
-the standard starting position, the game file includes the
-starting position used. Games are saved in the PGN (portable
-game notation) format, unless the oldSaveStyle option is true,
-in which case they are saved in an older format that is specific
-to XBoard. Both formats are human-readable, and both can be
-read back by the ‘<samp><span class="samp">Load Game</span></samp>’ command.

-<br><dt>Copy Game<dd><a name="index-Copy-Game_002c-Menu-Item-14"></a>Copies a record of the current game to an internal clipboard in PGN
-format and sets the X selection to the game text. The game can be
-pasted to another application (such as a text editor or another copy
-of XBoard) using that application's paste command. In many X
-applications, such as xterm and emacs, the middle mouse button can be
-used for pasting; in XBoard, you must use the Paste Game command.

<dl>
-<dt>Flip View<dd><a name="index-Flip-View_002c-Menu-Item-74"></a>Inverts your view of the chess board for the duration of the
-current game. Starting a new game returns the board to normal.
-The <kbd>v</kbd> key is a keyboard equivalent.
-<br><dt>Adjudications<dd><a name="index-Adjudications_002c-Menu-Item-75"></a>Pops up a sub-menu where you can enable or disable various adjudications
-that XBoard can perform in engine-engine games.
-You can instruct XBoard to detect and terminate the game on checkmate
-or stalemate, even if the engines would not do so, to verify engine
-result claims (forfeiting engines that make false claims), rather than
-naively following the engine, to declare draw on posititions
-which can never be won for lack of mating material, (e.g. KBK),
-or which are impossble to win unless the opponent seeks its own demise
-(e.g. KBKN).
-For these adjudications to work, ‘<samp><span class="samp">Test Legality</span></samp>’ should be switched on.
-It is also possible to insruct XBoard to enforce a 50-move or 3-fold-repeat
-rule and automtically declare draw (after a user-adjustable number of moves
-or repeats) even if the engines are prepared to go on.
-It is also possible to have XBoard declare draw on games that seem to drag on
-forever, or adjudicate a loss if both engines agree (for 3 cosecutive moves) that one
-of them is behind more than a user-adjustable score threshold.
-For the latter adjudication to work, XBoard should be able to properly understand
-the engine's scores. To faclitate the latter, you can inform xboard here if
-the engines report scores from the viewpoint of white, or from that of their own color.
-<br><dt>Engine Settings<dd>Pops up a sub-menu where you can set some engine parameters common to most engines,
-such as hash-table size, tablebase cache size, maximum number of processors
-that SMP engines can use, and where to find the Polyglot adapter needed
-to run UCI engines under XBoard. The feature tht allows setting of these parameters on
-engines is new since XBoard 4.3.15, so not many WinBoard engines respond
-to it yet, but UCI engines should.
-It is also possible to specify a GUI opening book here, i.e. an opening
-book that XBoard consults for any position a playing engine gets in.
-It then forces the engine to play the book move, rather than to think up its own,
-if that position is found in the book.
-The book can switched on and off independently for either engine.
-<br><dt>Time Control<dd><a name="index-Time-Control_002c-Menu-Item-76"></a>Pops up a sub-menu where you can set the time-control parameters interactively.
-Allows you to select classical or incremental time controls,
-set the moves per session, session duration, and time increment.
-Also allows specification of time-odds factors for one or both engines.
-If an engine is given a time-odds factor N, all time quota it gets,
-be it at the beginning of a session or through the time increment or
-fixed time per move, will be divided by N.
-<br><dt>Always Queen<dd><a name="index-Always-Queen_002c-Menu-Item-77"></a>If this option is off, XBoard brings up a dialog
-box whenever you move a pawn to the last rank, asking what piece
-you want to promote it to. If the option is true, your pawns are
-always promoted to queens. Your opponent can still underpromote.
-<br><dt>Animate Dragging<dd><a name="index-Animate-Dragging_002c-Menu-Item-78"></a>If Animate Dragging is on, while you are dragging a piece with the
-mouse, an image of the piece follows the mouse cursor.
-If Animate Dragging is off, there is no visual feedback while you are
-dragging a piece, but if Animate Moving is on, the move will be
-animated when it is complete.
-<br><dt>Animate Moving<dd><a name="index-Animate-Moving_002c-Menu-Item-79"></a>If Animate Moving is on, all piece moves are animated. An image of the
-piece is shown moving from the old square to the new square when the
-move is completed (unless the move was already animated by Animate Dragging).
-If Animate Moving is off, a moved piece instantly disappears from its
-old square and reappears on its new square when the move is complete.
-<br><dt>Auto Comment<dd><a name="index-Auto-Comment_002c-Menu-Item-80"></a>If this option is on, any remarks made on ICS while you are observing or
-playing a game are recorded as a comment on the current move. This includes
-remarks made with the ICS commands <kbd>say</kbd>, <kbd>tell</kbd>, <kbd>whisper</kbd>,
-and <kbd>kibitz</kbd>.
-Limitation: remarks that you type yourself are not recognized;
-XBoard scans only the output from ICS, not the input you type to it.
-<br><dt>Auto Flag<dd><a name="index-Auto-Flag_002c-Menu-Item-81"></a>If this option is on and one player runs out of time
-before the other,
-XBoard
-will automatically call his flag, claiming a win on time.
-In ICS mode, Auto Flag will only call your opponent's flag, not yours,
-and the ICS may award you a draw instead of a win if you have
-insufficient mating material. In local chess engine mode,
-XBoard
-may call either player's flag and will not take material into account.
-<br><dt>Auto Flip View<dd><a name="index-Auto-Flip-View_002c-Menu-Item-82"></a>If the Auto Flip View option is on when you start a game, the board
-will be automatically oriented so that your pawns move from the bottom
-of the window towards the top.
-<br><dt>Auto Observe<dd><a name="index-Auto-Observe_002c-Menu-Item-83"></a>If this option is on and you add a player to your <code>gnotify</code>
-list on ICS, XBoard will automatically observe all of that
-player's games, unless you are doing something else (such as
-observing or playing a game of your own) when one starts.
-The games are displayed
-from the point of view of the player on your gnotify list; that is, his
-pawns move from the bottom of the window towards the top.
-Exceptions: If both players in a game are on your gnotify list, if
-your ICS
-<code>highlight</code>
-variable is set to 0, or if the ICS you are using does not
-properly support observing from Black's point of view,
-you will see the game from White's point of view.
-<br><dt>Auto Raise Board<dd><a name="index-Auto-Raise-Board_002c-Menu-Item-84"></a>If this option is on, whenever a new game begins, the chessboard window
-is deiconized (if necessary) and raised to the top of the stack of windows.
-<br><dt>Auto Save<dd><a name="index-Auto-Save_002c-Menu-Item-85"></a>If this option is true, at the end of every game XBoard prompts
-you for a file name and appends a record of the game to the file
-you specify.
-Disabled if the <code>saveGameFile</code> command-line
-option is set, as in that case all games are saved to the specified file.
-See <a href="#Load-and-Save-options">Load and Save options</a>.
-<br><dt>Blindfold<dd><a name="index-Blindfold_002c-Menu-Item-86"></a>If this option is on, XBoard displays the board as usual but does
-not display pieces or move highlights. You can still move in the
-usual way (with the mouse or by typing moves in ICS mode), even though
-the pieces are invisible.
-<br><dt>Flash Moves<dd><a name="index-Flash-Moves_002c-Menu-Item-87"></a>If this option is on, whenever a move is completed, the moved piece flashes.
-The number of times to flash is set by the flashCount command-line
-option; it defaults to 3 if Flash Moves is first turned on from the menu.
-
- <p>If you are playing a game on an ICS, the board is always
-oriented at the start of the game so that your pawns move from
-the bottom of the window towards the top. Otherwise, the starting
-orientation is determined by the <code>flipView</code> command line option;
-if it is false (the default), White's pawns move from bottom to top
-at the start of each game; if it is true, Black's pawns move from
-bottom to top. See <a href="#User-interface-options">User interface options</a>.
-<br><dt>Get Move List<dd><a name="index-Get-Move-List_002c-Menu-Item-88"></a>If this option is on, whenever XBoard
-receives the first board of a new ICS game (or a different game from
-the one it is currently displaying), it
-retrieves the list of past moves from the ICS.
-You can then review the moves with the ‘<samp><span class="samp">Forward</span></samp>’ and ‘<samp><span class="samp">Backward</span></samp>’
-commands
-or save them with ‘<samp><span class="samp">Save Game</span></samp>’. You might want to
-turn off this option if you are observing several blitz games at once,
-to keep from wasting time and network bandwidth fetching the move lists over
-and over.
-When you turn this option on from the menu, XBoard
-immediately fetches the move list of the current game (if any).
-<br><dt>Highlight Last Move<dd><a name="index-Highlight-Last-Move_002c-Menu-Item-89"></a>If Highlight Last Move is on, after a move is made, the starting and
-ending squares remain highlighted. In addition, after you use Backward
-or Back to Start, the starting and ending squares of the last move to
-be unmade are highlighted.
-<br><dt>Move Sound<dd><a name="index-Move-Sound_002c-Menu-Item-90"></a>If this option is on, XBoard alerts you by playing a sound
-after each of your opponent's moves (or after every
-move if you are observing a game on the Internet Chess Server).
-The sound is not played after moves you make or moves read from a
-saved game file. By default, the
-sound is the terminal bell, but on some systems you can change it
-to a sound file using the soundMove option; see below.
-
- <p>If you turn on this option when using XBoard with the Internet
-Chess Server, you will probably want to give the
-<kbd>set bell 0</kbd>
-command to the ICS, since otherwise the ICS will ring the terminal bell
-after every move (not just yours). (The <samp><span class="file">.icsrc</span></samp> file
-is a good place for this; see <a href="#ICS-options">ICS options</a>.)
-<br><dt>ICS Alarm<dd><a name="index-ICS-Alarm_002c-Menu-Item-91"></a>When this option is on, an alarm sound is played when your clock
-counts down to the icsAlarmTime (by default, 5 seconds) in an ICS
-game. For games with time controls that include an increment, the
-alarm will sound each time the clock counts down to the icsAlarmTime.
-By default, the alarm sound is the terminal bell, but on some systems
-you can change it to a sound file using the soundIcsAlarm option; see
-below.
-<br><dt>Old Save Style<dd><a name="index-Old-Save-Style_002c-Menu-Item-92"></a>If this option is off, XBoard saves games in PGN
-(portable game notation) and positions in FEN (Forsythe-Edwards
-notation). If the option is on, a save style that is compatible
-with older versions of XBoard is used instead.
-The old position style is more human-readable
-than FEN; the old game style has no particular advantages.
-<br><dt>Periodic Updates<dd><a name="index-Periodic-Updates_002c-Menu-Item-93"></a>If this option is off (or if
-you are using a chess engine that does not support periodic updates),
-the analysis window
-will only be updated when the analysis changes. If this option is
-on, the Analysis Window will be updated every two seconds.
-<br><dt>Ponder Next Move<dd><a name="index-Ponder-Next-Move_002c-Menu-Item-94"></a>If this option is off, the chess engine will think only when it is on
-move. If the option is on, the engine will also think while waiting
-for you to make your move.
-<br><dt>Popup Exit Message<dd><a name="index-Popup-Exit-Message_002c-Menu-Item-95"></a>If this option is on, when XBoard wants to display a message just
-before exiting, it brings up a modal dialog box and waits for you to
-click OK before exiting. If the option is off, XBoard prints the
-message to standard error (the terminal) and exits immediately.
-<br><dt>Popup Move Errors<dd><a name="index-Popup-Move-Errors_002c-Menu-Item-96"></a>If this option is off, when you make an error in moving (such as
-attempting an illegal move or moving the wrong color piece), the
-error message is displayed in the message area. If the option is
-on, move errors are displayed in small popup windows like other errors.
-You can dismiss an error popup either by clicking its OK button or by
-clicking anywhere on the board, including downclicking to start a move.
-<br><dt>Premove<dd><a name="index-Premove_002c-Menu-Item-97"></a>If this option is on while playing a game on an ICS, you can register
-your next planned move before it is your turn. Move the piece with
-the mouse in the ordinary way, and the starting and ending squares
-will be highlighted with a special color (red by default). When it is
-your turn, if your registered move is legal, XBoard will send it to
-ICS immediately; if not, it will be ignored and you can make a
-different move. If you change your mind about your premove, either
-make a different move, or double-click on any piece to cancel the move
-entirely.
-<br><dt>Quiet Play<dd><a name="index-Quiet-Play_002c-Menu-Item-98"></a>If this option is on, XBoard will automatically issue an ICS
-<kbd>set shout 0</kbd>
-command whenever you start a game and a
-<kbd>set shout 1</kbd>
-command whenever you finish one. Thus, you will not be distracted
-by shouts from other ICS users while playing.
-<br><dt>Show Coords<dd><a name="index-Show-Coords_002c-Menu-Item-99"></a>If this option is on, XBoard displays algebraic coordinates
-along the board's left and bottom edges.
-<br><dt>Hide Thinking<dd><a name="index-Hide-Thinking_002c-Menu-Item-100"></a>If this option is off, the chess engine's notion of the score and best
-line of play from the current position is displayed as it is
-thinking. The score indicates how many pawns ahead (or if negative,
-behind) the chess engine thinks it is. In matches between two
-machines, the score is prefixed by ‘<samp><span class="samp">W</span></samp>’ or ‘<samp><span class="samp">B</span></samp>’ to indicate
-whether it is showing White's thinking or Black's, and only the thinking
-of the engine that is on move is shown.
-<br><dt>Test Legality<dd><a name="index-Test-Legality_002c-Menu-Item-101"></a>If this option is on, XBoard tests whether the moves you try to make
-with the mouse are legal and refuses to let you make an illegal move.
-Moves loaded from a file with ‘<samp><span class="samp">Load Game</span></samp>’ are also checked. If
-the option is off, all moves are accepted, but if a local chess engine
-or the ICS is active, they will still reject illegal moves. Turning
-off this option is useful if you are playing a chess variant with
-rules that XBoard does not understand. (Bughouse, suicide, and wild
-variants where the king may castle after starting on the d file are
-generally supported with Test Legality on.)
+<dt>Flip View<dd><a name="index-Flip-View_002c-Menu-Item-74"></a>Inverts your view of the chess board for the duration of the\r
+current game. Starting a new game returns the board to normal.\r
+The <kbd>v</kbd> key is a keyboard equivalent.\r
+<br><dt>Adjudications<dd><a name="index-Adjudications_002c-Menu-Item-75"></a>Pops up a sub-menu where you can enable or disable various adjudications\r
+that XBoard can perform in engine-engine games.\r
+You can instruct XBoard to detect and terminate the game on checkmate\r
+or stalemate, even if the engines would not do so, to verify engine\r
+result claims (forfeiting engines that make false claims), rather than\r
+naively following the engine, to declare draw on posititions\r
+which can never be won for lack of mating material, (e.g. KBK),\r
+or which are impossble to win unless the opponent seeks its own demise \r
+(e.g. KBKN).\r
+For these adjudications to work, ‘<samp><span class="samp">Test Legality</span></samp>’ should be switched on.\r
+It is also possible to insruct XBoard to enforce a 50-move or 3-fold-repeat\r
+rule and automtically declare draw (after a user-adjustable number of moves\r
+or repeats) even if the engines are prepared to go on.\r
+It is also possible to have XBoard declare draw on games that seem to drag on \r
+forever, or adjudicate a loss if both engines agree (for 3 cosecutive moves) that one\r
+of them is behind more than a user-adjustable score threshold.\r
+For the latter adjudication to work, XBoard should be able to properly understand\r
+the engine's scores. To faclitate the latter, you can inform xboard here if\r
+the engines report scores from the viewpoint of white, or from that of their own color.\r
+<br><dt>Engine Settings<dd>Pops up a sub-menu where you can set some engine parameters common to most engines,\r
+such as hash-table size, tablebase cache size, maximum number of processors\r
+that SMP engines can use, and where to find the Polyglot adapter needed\r
+to run UCI engines under XBoard. The feature tht allows setting of these parameters on\r
+engines is new since XBoard 4.3.15, so not many WinBoard engines respond\r
+to it yet, but UCI engines should.\r
+It is also possible to specify a GUI opening book here, i.e. an opening\r
+book that XBoard consults for any position a playing engine gets in.\r
+It then forces the engine to play the book move, rather than to think up its own,\r
+if that position is found in the book.\r
+The book can switched on and off independently for either engine.\r
+<br><dt>Time Control<dd><a name="index-Time-Control_002c-Menu-Item-76"></a>Pops up a sub-menu where you can set the time-control parameters interactively.\r
+Allows you to select classical or incremental time controls,\r
+set the moves per session, session duration, and time increment.\r
+Also allows specification of time-odds factors for one or both engines.\r
+If an engine is given a time-odds factor N, all time quota it gets, \r
+be it at the beginning of a session or through the time increment or\r
+fixed time per move, will be divided by N.\r
+<br><dt>Always Queen<dd><a name="index-Always-Queen_002c-Menu-Item-77"></a>If this option is off, XBoard brings up a dialog\r
+box whenever you move a pawn to the last rank, asking what piece\r
+you want to promote it to. If the option is true, your pawns are\r
+always promoted to queens. Your opponent can still underpromote.\r
+<br><dt>Animate Dragging<dd><a name="index-Animate-Dragging_002c-Menu-Item-78"></a>If Animate Dragging is on, while you are dragging a piece with the\r
+mouse, an image of the piece follows the mouse cursor.\r
+If Animate Dragging is off, there is no visual feedback while you are\r
+dragging a piece, but if Animate Moving is on, the move will be\r
+animated when it is complete. \r
+<br><dt>Animate Moving<dd><a name="index-Animate-Moving_002c-Menu-Item-79"></a>If Animate Moving is on, all piece moves are animated. An image of the\r
+piece is shown moving from the old square to the new square when the\r
+move is completed (unless the move was already animated by Animate Dragging).\r
+If Animate Moving is off, a moved piece instantly disappears from its\r
+old square and reappears on its new square when the move is complete.\r
+<br><dt>Auto Comment<dd><a name="index-Auto-Comment_002c-Menu-Item-80"></a>If this option is on, any remarks made on ICS while you are observing or\r
+playing a game are recorded as a comment on the current move. This includes\r
+remarks made with the ICS commands <kbd>say</kbd>, <kbd>tell</kbd>, <kbd>whisper</kbd>,\r
+and <kbd>kibitz</kbd>.\r
+Limitation: remarks that you type yourself are not recognized;\r
+XBoard scans only the output from ICS, not the input you type to it.\r
+<br><dt>Auto Flag<dd><a name="index-Auto-Flag_002c-Menu-Item-81"></a>If this option is on and one player runs out of time\r
+before the other,\r
+XBoard\r
+will automatically call his flag, claiming a win on time.\r
+In ICS mode, Auto Flag will only call your opponent's flag, not yours,\r
+and the ICS may award you a draw instead of a win if you have\r
+insufficient mating material. In local chess engine mode,\r
+XBoard\r
+may call either player's flag and will not take material into account.\r
+<br><dt>Auto Flip View<dd><a name="index-Auto-Flip-View_002c-Menu-Item-82"></a>If the Auto Flip View option is on when you start a game, the board\r
+will be automatically oriented so that your pawns move from the bottom\r
+of the window towards the top.\r
+<br><dt>Auto Observe<dd><a name="index-Auto-Observe_002c-Menu-Item-83"></a>If this option is on and you add a player to your <code>gnotify</code>\r
+list on ICS, XBoard will automatically observe all of that\r
+player's games, unless you are doing something else (such as\r
+observing or playing a game of your own) when one starts.\r
+The games are displayed \r
+from the point of view of the player on your gnotify list; that is, his\r
+pawns move from the bottom of the window towards the top.\r
+Exceptions: If both players in a game are on your gnotify list, if\r
+your ICS \r
+<code>highlight</code>\r
+variable is set to 0, or if the ICS you are using does not \r
+properly support observing from Black's point of view,\r
+you will see the game from White's point of view.\r
+<br><dt>Auto Raise Board<dd><a name="index-Auto-Raise-Board_002c-Menu-Item-84"></a>If this option is on, whenever a new game begins, the chessboard window\r
+is deiconized (if necessary) and raised to the top of the stack of windows.\r
+<br><dt>Auto Save<dd><a name="index-Auto-Save_002c-Menu-Item-85"></a>If this option is true, at the end of every game XBoard prompts\r
+you for a file name and appends a record of the game to the file\r
+you specify. \r
+Disabled if the <code>saveGameFile</code> command-line\r
+option is set, as in that case all games are saved to the specified file.\r
+See <a href="#Load-and-Save-options">Load and Save options</a>.\r
+<br><dt>Blindfold<dd><a name="index-Blindfold_002c-Menu-Item-86"></a>If this option is on, XBoard displays the board as usual but does\r
+not display pieces or move highlights. You can still move in the\r
+usual way (with the mouse or by typing moves in ICS mode), even though\r
+the pieces are invisible.\r
+<br><dt>Flash Moves<dd><a name="index-Flash-Moves_002c-Menu-Item-87"></a>If this option is on, whenever a move is completed, the moved piece flashes.\r
+The number of times to flash is set by the flashCount command-line\r
+option; it defaults to 3 if Flash Moves is first turned on from the menu.\r
+\r
+If you are playing a game on an ICS, the board is always\r
+oriented at the start of the game so that your pawns move from\r
+the bottom of the window towards the top. Otherwise, the starting\r
+orientation is determined by the <code>flipView</code> command line option;\r
+if it is false (the default), White's pawns move from bottom to top\r
+at the start of each game; if it is true, Black's pawns move from\r
+bottom to top. See <a href="#User-interface-options">User interface options</a>.\r
+<br><dt>Get Move List<dd><a name="index-Get-Move-List_002c-Menu-Item-88"></a>If this option is on, whenever XBoard\r
+receives the first board of a new ICS game (or a different game from\r
+the one it is currently displaying), it\r
+retrieves the list of past moves from the ICS.\r
+You can then review the moves with the ‘<samp><span class="samp">Forward</span></samp>’ and ‘<samp><span class="samp">Backward</span></samp>’\r
+commands\r
+or save them with ‘<samp><span class="samp">Save Game</span></samp>’. You might want to\r
+turn off this option if you are observing several blitz games at once,\r
+to keep from wasting time and network bandwidth fetching the move lists over\r
+and over.\r
+When you turn this option on from the menu, XBoard\r
+immediately fetches the move list of the current game (if any).\r
+<br><dt>Highlight Last Move<dd><a name="index-Highlight-Last-Move_002c-Menu-Item-89"></a>If Highlight Last Move is on, after a move is made, the starting and\r
+ending squares remain highlighted. In addition, after you use Backward\r
+or Back to Start, the starting and ending squares of the last move to\r
+be unmade are highlighted.\r
+<br><dt>Move Sound<dd><a name="index-Move-Sound_002c-Menu-Item-90"></a>If this option is on, XBoard alerts you by playing a sound\r
+after each of your opponent's moves (or after every\r
+move if you are observing a game on the Internet Chess Server).\r
+The sound is not played after moves you make or moves read from a\r
+saved game file. By default, the\r
+sound is the terminal bell, but on some systems you can change it\r
+to a sound file using the soundMove option; see below.\r
+\r
+If you turn on this option when using XBoard with the Internet\r
+Chess Server, you will probably want to give the\r
+<kbd>set bell 0</kbd>\r
+command to the ICS, since otherwise the ICS will ring the terminal bell\r
+after every move (not just yours). (The <samp><span class="file">.icsrc</span></samp> file\r
+is a good place for this; see <a href="#ICS-options">ICS options</a>.)\r
+<br><dt>ICS Alarm<dd><a name="index-ICS-Alarm_002c-Menu-Item-91"></a>When this option is on, an alarm sound is played when your clock\r
+counts down to the icsAlarmTime (by default, 5 seconds) in an ICS\r
+game. For games with time controls that include an increment, the\r
+alarm will sound each time the clock counts down to the icsAlarmTime.\r
+By default, the alarm sound is the terminal bell, but on some systems\r
+you can change it to a sound file using the soundIcsAlarm option; see\r
+below.\r
+<br><dt>Old Save Style<dd><a name="index-Old-Save-Style_002c-Menu-Item-92"></a>If this option is off, XBoard saves games in PGN\r
+(portable game notation) and positions in FEN (Forsythe-Edwards\r
+notation). If the option is on, a save style that is compatible\r
+with older versions of XBoard is used instead.\r
+The old position style is more human-readable\r
+than FEN; the old game style has no particular advantages.\r
+<br><dt>Periodic Updates<dd><a name="index-Periodic-Updates_002c-Menu-Item-93"></a>If this option is off (or if\r
+you are using a chess engine that does not support periodic updates),\r
+the analysis window\r
+will only be updated when the analysis changes. If this option is\r
+on, the Analysis Window will be updated every two seconds.\r
+<br><dt>Ponder Next Move<dd><a name="index-Ponder-Next-Move_002c-Menu-Item-94"></a>If this option is off, the chess engine will think only when it is on\r
+move. If the option is on, the engine will also think while waiting\r
+for you to make your move.\r
+<br><dt>Popup Exit Message<dd><a name="index-Popup-Exit-Message_002c-Menu-Item-95"></a>If this option is on, when XBoard wants to display a message just\r
+before exiting, it brings up a modal dialog box and waits for you to\r
+click OK before exiting. If the option is off, XBoard prints the\r
+message to standard error (the terminal) and exits immediately.\r
+<br><dt>Popup Move Errors<dd><a name="index-Popup-Move-Errors_002c-Menu-Item-96"></a>If this option is off, when you make an error in moving (such as\r
+attempting an illegal move or moving the wrong color piece), the\r
+error message is displayed in the message area. If the option is\r
+on, move errors are displayed in small popup windows like other errors.\r
+You can dismiss an error popup either by clicking its OK button or by\r
+clicking anywhere on the board, including downclicking to start a move.\r
+<br><dt>Premove<dd><a name="index-Premove_002c-Menu-Item-97"></a>If this option is on while playing a game on an ICS, you can register\r
+your next planned move before it is your turn. Move the piece with\r
+the mouse in the ordinary way, and the starting and ending squares\r
+will be highlighted with a special color (red by default). When it is\r
+your turn, if your registered move is legal, XBoard will send it to\r
+ICS immediately; if not, it will be ignored and you can make a\r
+different move. If you change your mind about your premove, either\r
+make a different move, or double-click on any piece to cancel the move\r
+entirely.\r
+<br><dt>Quiet Play<dd><a name="index-Quiet-Play_002c-Menu-Item-98"></a>If this option is on, XBoard will automatically issue an ICS\r
+<kbd>set shout 0</kbd>\r
+command whenever you start a game and a\r
+<kbd>set shout 1</kbd>\r
+command whenever you finish one. Thus, you will not be distracted\r
+by shouts from other ICS users while playing.\r
+<br><dt>Show Coords<dd><a name="index-Show-Coords_002c-Menu-Item-99"></a>If this option is on, XBoard displays algebraic coordinates\r
+along the board's left and bottom edges.\r
+<br><dt>Hide Thinking<dd><a name="index-Hide-Thinking_002c-Menu-Item-100"></a>If this option is off, the chess engine's notion of the score and best\r
+line of play from the current position is displayed as it is\r
+thinking. The score indicates how many pawns ahead (or if negative,\r
+behind) the chess engine thinks it is. In matches between two\r
+machines, the score is prefixed by ‘<samp><span class="samp">W</span></samp>’ or ‘<samp><span class="samp">B</span></samp>’ to indicate\r
+whether it is showing White's thinking or Black's, and only the thinking\r
+of the engine that is on move is shown.\r
+<br><dt>Test Legality<dd><a name="index-Test-Legality_002c-Menu-Item-101"></a>If this option is on, XBoard tests whether the moves you try to make\r
+with the mouse are legal and refuses to let you make an illegal move.\r
+Moves loaded from a file with ‘<samp><span class="samp">Load Game</span></samp>’ are also checked. If\r
+the option is off, all moves are accepted, but if a local chess engine\r
+or the ICS is active, they will still reject illegal moves. Turning\r
+off this option is useful if you are playing a chess variant with\r
+rules that XBoard does not understand. (Bughouse, suicide, and wild\r
+variants where the king may castle after starting on the d file are\r
+generally supported with Test Legality on.)\r

-This section documents the command-line options to XBoard. You can
-set these options in two ways: by typing them on the shell command
-line you use to start XBoard, or by setting them as X resources
-(typically in your <samp><span class="file">.Xresources</span></samp> file). Many of the options
-cannot be changed while XBoard is running; others set the initial
-state of items that can be changed with the <a href="#Options">Options</a> menu.
-
- <p>Most of the options have both a long name and a short name. To turn a
-boolean option on or off from the command line, either give its long
-name followed by the value true or false
-(‘<samp><span class="samp">-longOptionName true</span></samp>’), or give just the short name to turn the
-option on (‘<samp><span class="samp">-opt</span></samp>’), or the short name preceded by ‘<samp><span class="samp">x</span></samp>’ to
-turn the option off (‘<samp><span class="samp">-xopt</span></samp>’). For options that take strings or
-numbers as values, you can use the long or short option names
-interchangeably.
-
- <p>Each option corresponds to an X resource with the same name, so
-if you like, you can set options in your <samp><span class="file">.Xresources</span></samp> file
-or in a file named <samp><span class="file">XBoard</span></samp> in your home directory.
-For options that have two names, the longer one is the name of
-the corresponding X resource; the short name is not recognized.
-To turn a boolean option on or off as an
-X resource, give its long name followed by the value
-true or false (‘<samp><span class="samp">XBoard*longOptionName: true</span></samp>’).

<dl>
-<dt>-tc or -timeControl minutes[:seconds]<dd><a name="index-tc_002c-option-115"></a><a name="index-timeControl_002c-option-116"></a>Each player begins with his clock set to the <code>timeControl</code> period.
-Default: 5 minutes.
-The additional options <code>movesPerSession</code> and <code>timeIncrement</code>
-are mutually exclusive.
-<br><dt>-mps or -movesPerSession moves<dd><a name="index-mps_002c-option-117"></a><a name="index-movesPerSession_002c-option-118"></a>When both players have made <code>movesPerSession</code> moves, a
-new <code>timeControl</code> period is added to both clocks. Default: 40 moves.
-<br><dt>-inc or -timeIncrement seconds<dd><a name="index-inc_002c-option-119"></a><a name="index-timeIncrement_002c-option-120"></a>If this option is specified, <code>movesPerSession</code> is ignored.
-Instead, after each player's move, <code>timeIncrement</code> seconds are
-added to his clock.
-Use ‘<samp><span class="samp">-inc 0</span></samp>’ if you want to require the entire
-game to be played in one <code>timeControl</code> period, with no increment.
-Default: -1, which specifies <code>movesPerSession</code> mode.
-<br><dt>-clock/-xclock or -clockMode true/false<dd><a name="index-clock_002c-option-121"></a><a name="index-clockMode_002c-option-122"></a>Determines whether or not to display the chess clocks. If clockMode is
-false, the clocks are not shown, but the side that is to play next
-is still highlighted. Also, unless <code>searchTime</code>
-is set, the chess engine still keeps track of the clock time and uses it to
-determine how fast to make its moves.
-<br><dt>-st or -searchTime minutes[:seconds]<dd><a name="index-st_002c-option-123"></a><a name="index-searchTime_002c-option-124"></a>Tells the chess engine to spend at most the given amount of time
-searching for each of its moves. Without this option, the chess engine
-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.
-<br><dt>-depth or -searchDepth number<dd><a name="index-sd_002c-option-125"></a><a name="index-searchDepth_002c-option-126"></a>Tells the chess engine to look ahead at most the given number of moves
-when searching for a move to make. Without this option, the chess
-engine chooses its search depth based on the number of moves and
-amount of time remaining until the next time control. With the option,
-the engine will cut off its search early if it reaches the specified depth.
-<br><dt>-firstNPS number<dt>-secondNPS number<dd><a name="index-firstNPS_002c-option-127"></a><a name="index-secondNPS_002c-option-128"></a>Tells the chess engine to use an internal time standard based on its node count,
-rather then wall-clock time, to make its timing decisions.
-The time in virtual seconds should be obtained by dividing the node count
-through the given number, like the number was a rate in nodes per second.
-Xboard will manage the clocks in accordance with this, relying on the number
-of nodes reported by the engine in its thinking output. If the given number equals zero,
-it can obviously not be used to convert nodes to seconds, and the time reported
-by the engine is used to decrement the XBoard clock in stead. The engine is supposed to
-report in CPU time it uses, rather than wall-clock time, in this mode. This option
-can provide fairer conditions for engine-engine matches on heavily loaded machines,
-or with very fast games (where the wall clock is too inaccurate).
-<code>showThinking</code> must be on for this option to work. Default: -1 (off).
-Not many engines might support this yet!
-<br><dt>-firstTimeOdds factor<dt>-secondTimeOdds factor<dd><a name="index-firstTimeOdds_002c-option-129"></a><a name="index-secondTimeOdds_002c-option-130"></a>Reduces the time given to the mentioned engine by the given factor.
-If pondering is off, the effect is indistinguishable from what would happen
-if the engine was running on an n-times slower machine. Default: 1.
-<br><dt>-timeOddsMode mode<dd><a name="index-timeOddsMode_002c-option-131"></a>This option determines how the case is handled where both engines have a time-odds handicap.
-If mode=1, the engine that gets the most time will always get the nominal time,
-as specified by the time-control options, and its opponent's time is renormalized accordingly.
-If mode=0, both play with reduced time. Default: 0.
-<br><dt>-hideThinkingFromHuman true/false<dd>Controls the Hide Thinking option. See <a href="#Options-Menu">Options Menu</a>. Default: true.
-(Relaces the Show-Thinking option of older xboard versions.)
-<br><dt>-thinking/-xthinking or -showThinking true/false<dd><a name="index-thinking_002c-option-132"></a><a name="index-showThinking_002c-option-133"></a>Forces the engine to send thinking output to xboard.
-Used to be the only way to control if thinking output was displayed
-in older xboard versions,
-but as the thinking output in xboard 4.3 is also used for several other
-purposes (adjudication, storing in PGN file) the display of it is now controlled
-by the new option Hide Thinking. See <a href="#Options-Menu">Options Menu</a>. Default: false.
-(But if xboard needs the thinking output for some purpose,
-it makes the engine send it despite the setting of this option.)
-<br><dt>-ponder/-xponder or -ponderNextMove true/false<dd><a name="index-ponder_002c-option-134"></a><a name="index-ponderNextMove_002c-option-135"></a>Sets the Ponder Next Move menu option. See <a href="#Options-Menu">Options Menu</a>. Default: true.
-<br><dt>-smpCores number<dd>Specifies the maxmum nmber of CPUs an SMP engine is allowed to use.
-Only works for engines that support the WinBoard-protocol cores feature.
-<br><dt>-mg or -matchGames n<dd><a name="index-mg_002c-option-136"></a><a name="index-matchGames_002c-option-137"></a>Automatically runs an n-game match between two chess engines,
-with alternating colors.
-If the <code>loadGameFile</code> or <code>loadPositionFile</code> option is set,
-XBoard
-starts each game with the given opening moves or the given position;
-otherwise, the games start with the standard initial chess position.
-If the <code>saveGameFile</code> option is set, a move record for the
-match is appended to the specified file. If the <code>savePositionFile</code>
-option is set, the final position reached in each game of the match is appended
-to the specified file. When the match is over, XBoard
-displays the match score and exits. Default: 0 (do not run a match).
-<br><dt>-mm/-xmm or -matchMode true/false<dd><a name="index-mm_002c-option-138"></a><a name="index-matchMode_002c-option-139"></a>Setting <code>matchMode</code> to true is equivalent to setting
-<code>matchGames</code> to 1.
-<br><dt>-sameColorGames n<dd><a name="index-sameColorGames_002c-option-140"></a>Automatically runs an n-game match between two chess engines,
-without alternating colors.
-Otherwise the same applies as for the ‘<samp><span class="samp">-matchGames</span></samp>’ option,
-over which it takes precedence if both are specified. (See there.)
-Default: 0 (do not run a match).
-<br><dt>-fcp or -firstChessProgram program<dd><a name="index-fcp_002c-option-141"></a><a name="index-firstChessProgram_002c-option-142"></a>Name of first chess engine.
-Default: <samp><span class="file">Fairy-Max</span></samp>.
-<br><dt>-scp or -secondChessProgram program<dd><a name="index-scp_002c-option-143"></a><a name="index-secondChessProgram_002c-option-144"></a>Name of second chess engine, if needed.
-A second chess engine is started only in Two Machines (match) mode.
-Default: <samp><span class="file">Fairy-Max</span></samp>.
-<br><dt>-fb/-xfb or -firstPlaysBlack true/false<dd><a name="index-fb_002c-option-145"></a><a name="index-firstPlaysBlack_002c-option-146"></a>In games between two chess engines, firstChessProgram normally plays
-white. If this option is true, firstChessProgram plays black. In a
-multi-game match, this option affects the colors only for the first
-game; they still alternate in subsequent games.
-<br><dt>-fh or -firstHost host<dt>-sh or -secondHost host<dd><a name="index-fh_002c-option-147"></a><a name="index-firstHost_002c-option-148"></a><a name="index-sh_002c-option-149"></a><a name="index-secondHost_002c-option-150"></a>Hosts on which the chess engines are to run. The default for
-each is <samp><span class="file">localhost</span></samp>. If you specify another host, XBoard
-uses <samp><span class="file">rsh</span></samp> to run the chess engine there. (You can substitute a
-different remote shell program for rsh using the <code>remoteShell</code>
-option described below.)
-<br><dt>-fd or -firstDirectory dir<dt>-sd or -secondDirectory dir<dd><a name="index-fd_002c-option-151"></a><a name="index-firstDirectory_002c-option-152"></a><a name="index-sd_002c-option-153"></a><a name="index-secondDirectory_002c-option-154"></a>Working directories in which the chess engines are to be run.
-The default is "", which means to run the chess engine
-in the same working directory as XBoard
-itself. (See the CHESSDIR environment variable.)
-This option is effective only when the chess engine is being run
-on the local host; it does not work if the engine is run remotely
-using the -fh or -sh option.
-<br><dt>-initString string<dt>-secondInitString string<dd><a name="index-initString_002c-option-155"></a><a name="index-secondInitString_002c-option-156"></a>The string that is sent to initialize each chess engine for a new game.

-or Tiny 21x21.
-Pieces of all these sizes are built into XBoard.
-Other sizes can
-be used if you have them; see the pixmapDirectory and bitmapDirectory
-options.
-The default depends on the size of your screen; it is approximately the
-largest size that will fit without clipping.
-
- <p>You can select other sizes or vary other layout parameters by providing
-a list of comma-separated values (with no spaces) as the argument.
-You do not need to provide all the values; for any you omit from the
-end of the list, defaults are taken from the nearest built-in size.
-The value <code>n1</code> gives the piece size, <code>n2</code> the width of the
-black border
-between squares, <code>n3</code> the desired size for the
-clockFont, <code>n4</code> the desired size for the coordFont,
-<code>n5</code> the desired size for the default font,
-<code>n6</code> the smallLayout flag (0 or 1),
-and <code>n7</code> the tinyLayout flag (0 or 1).
-All dimensions are in pixels.
-If the border between squares is eliminated (0 width), the various
-highlight options will not work, as there is nowhere to draw the highlight.
-If smallLayout is 1 and <code>titleInWindow</code> is true,
-the window layout is rearranged to make more room for the title.
-If tinyLayout is 1, the labels on the menu bar are abbreviated
-to one character each and the buttons in the button bar are made narrower.

-<br><dt>-flip/-xflip or -flipView true/false<dd><a name="index-flip_002c-option-305"></a><a name="index-flipView_002c-option-306"></a>If Auto Flip View is not set, or if you are observing but not participating
-in a game, then the positioning of the board at the start of each game
-depends on the flipView option. If flipView is false (the default),
-the board is positioned so that the white pawns move from the bottom to the
-top; if true, the black pawns move from the bottom to the top.
-In any case, the Flip menu option (see <a href="#Options-Menu">Options Menu</a>)

-the board size being used.
-Default: -*-helvetica-medium-r-normal–*-*-*-*-*-*-*-*.
-<br><dt>-fontSizeTolerance tol<dd><a name="index-fontSizeTolerance_002c-option-327"></a>In the font selection algorithm, a nonscalable font will be preferred
-over a scalable font if the nonscalable font's size differs
-by <code>tol</code> pixels
-or less from the desired size. A value of -1 will force
-a scalable font to always be used if available; a value of 0 will
-use a nonscalable font only if it is exactly the right size;
-a large value (say 1000) will force a nonscalable font to always be
-used if available. Default: 4.
-<br><dt>-bm or -bitmapDirectory dir<dt>-pixmap or -pixmapDirectory dir<dd><a name="index-bm_002c-option-328"></a><a name="index-bitmapDirectory_002c-option-329"></a><a name="index-pixmap_002c-option-330"></a><a name="index-pixmapDirectory_002c-option-331"></a>These options control what piece images xboard uses. The XBoard
-distribution includes one set of pixmap pieces in xpm format, in the
-directory <samp><span class="file">pixmaps</span></samp>, and one set of bitmap pieces in xbm format,
-in the directory <samp><span class="file">bitmaps</span></samp>. Pixmap
-pieces give a better appearance on the screen: the white pieces have
-dark borders, and the black pieces have opaque internal details. With
-bitmaps, neither piece color has a border, and the internal details
-are transparent; you see the square color or other background color
-through them.
-
- <p>If XBoard is configured and compiled on a system that includes libXpm,
-the X pixmap library, the xpm pixmap pieces are compiled in as the
-default. A different xpm piece set can be selected at runtime with
-the <code>pixmapDirectory</code> option, or a bitmap piece set can be selected
-with the <code>bitmapDirectory</code> option.
-
- <p>If XBoard is configured and compiled on a system that does not include
-libXpm (or the <code>--disable-xpm</code> option is given to the configure
-program), the bitmap pieces are compiled in as the default. It is not
-possible to use xpm pieces in this case, but pixmap pieces in another
-format called "xim" can be used by giving the <code>pixmapDirectory</code> option.
-Or again, a different bitmap piece set can be selected with the
-<code>bitmapDirectory</code> option.
-
- <p>Files in the <code>bitmapDirectory</code> must be named as follows:
-The first character of a piece bitmap name gives the piece it
-represents (‘<samp><span class="samp">p</span></samp>’, ‘<samp><span class="samp">n</span></samp>’, ‘<samp><span class="samp">b</span></samp>’, ‘<samp><span class="samp">r</span></samp>’, ‘<samp><span class="samp">q</span></samp>’, or ‘<samp><span class="samp">k</span></samp>’),
-the next characters give the size in pixels, the
-following character indicates whether the piece is
-solid or outline (‘<samp><span class="samp">s</span></samp>’ or ‘<samp><span class="samp">o</span></samp>’),
-and the extension is ‘<samp><span class="samp">.bm</span></samp>’.
-For example, a solid 80x80 knight would be named <samp><span class="file">n80s.bm</span></samp>.
-The outline bitmaps are used only in monochrome mode.
-If bitmap pieces are compiled in and the bitmapDirectory is missing
-some files, the compiled in pieces are used instead.
-
- <p>If the bitmapDirectory option is given,
-it is also possible to replace xboard's icons and menu checkmark,
-by supplying files named <samp><span class="file">icon_white.bm</span></samp>, <samp><span class="file">icon_black.bm</span></samp>, and
-<samp><span class="file">checkmark.bm</span></samp>.

+of the pieces and setting a few related parameters.\r
+The sizeName can be one of: Titanic, giving 129x129 pixel pieces,\r
+Colossal 116x116, Giant 108x108, Huge 95x95, Big 87x87, Large 80x80, Bulky 72x72,\r
+Medium 64x64, Moderate 58x58, Average 54x54, Middling 49x49, Mediocre\r
+45x45, Small 40x40, Slim 37x37, Petite 33x33, Dinky 29x29, Teeny 25x25,\r
+or Tiny 21x21.\r
+Pieces of all these sizes are built into XBoard.\r
+Other sizes can\r
+be used if you have them; see the pixmapDirectory and bitmapDirectory\r
+options.\r
+The default depends on the size of your screen; it is approximately the\r
+largest size that will fit without clipping.\r
+\r
+You can select other sizes or vary other layout parameters by providing\r
+a list of comma-separated values (with no spaces) as the argument.\r
+You do not need to provide all the values; for any you omit from the\r
+end of the list, defaults are taken from the nearest built-in size.\r
+The value <code>n1</code> gives the piece size, <code>n2</code> the width of the\r
+black border\r
+between squares, <code>n3</code> the desired size for the \r
+clockFont, <code>n4</code> the desired size for the coordFont,\r
+<code>n5</code> the desired size for the default font,\r
+<code>n6</code> the smallLayout flag (0 or 1), \r
+and <code>n7</code> the tinyLayout flag (0 or 1). \r
+All dimensions are in pixels.\r
+If the border between squares is eliminated (0 width), the various\r
+highlight options will not work, as there is nowhere to draw the highlight.\r
+If smallLayout is 1 and <code>titleInWindow</code> is true, \r
+the window layout is rearranged to make more room for the title.\r
+If tinyLayout is 1, the labels on the menu bar are abbreviated\r
+to one character each and the buttons in the button bar are made narrower.\r

+in a game, then the positioning of the board at the start of each game\r
+depends on the flipView option. If flipView is false (the default),\r
+the board is positioned so that the white pawns move from the bottom to the\r

+over a scalable font if the nonscalable font's size differs\r
+by <code>tol</code> pixels\r
+or less from the desired size. A value of -1 will force\r
+a scalable font to always be used if available; a value of 0 will\r
+use a nonscalable font only if it is exactly the right size; \r
+a large value (say 1000) will force a nonscalable font to always be\r
+used if available. Default: 4.\r
+<br><dt>-bm or -bitmapDirectory dir<dt>-pixmap or -pixmapDirectory dir<dd><a name="index-bm_002c-option-329"></a><a name="index-bitmapDirectory_002c-option-330"></a><a name="index-pixmap_002c-option-331"></a><a name="index-pixmapDirectory_002c-option-332"></a>These options control what piece images xboard uses. The XBoard\r
+distribution includes one set of pixmap pieces in xpm format, in the\r
+directory <samp><span class="file">pixmaps</span></samp>, and one set of bitmap pieces in xbm format,\r
+in the directory <samp><span class="file">bitmaps</span></samp>. Pixmap\r
+pieces give a better appearance on the screen: the white pieces have\r
+dark borders, and the black pieces have opaque internal details. With\r
+bitmaps, neither piece color has a border, and the internal details\r
+are transparent; you see the square color or other background color\r
+through them.\r
+\r
+If XBoard is configured and compiled on a system that includes libXpm,\r
+the X pixmap library, the xpm pixmap pieces are compiled in as the\r
+default. A different xpm piece set can be selected at runtime with\r
+the <code>pixmapDirectory</code> option, or a bitmap piece set can be selected\r
+with the <code>bitmapDirectory</code> option.\r
+\r
+If XBoard is configured and compiled on a system that does not include\r
+libXpm (or the <code>--disable-xpm</code> option is given to the configure\r
+program), the bitmap pieces are compiled in as the default. It is not\r
+possible to use xpm pieces in this case, but pixmap pieces in another\r
+format called "xim" can be used by giving the <code>pixmapDirectory</code> option.\r
+Or again, a different bitmap piece set can be selected with the\r
+<code>bitmapDirectory</code> option.\r
+\r
+Files in the <code>bitmapDirectory</code> must be named as follows:\r
+The first character of a piece bitmap name gives the piece it \r
+represents (‘<samp><span class="samp">p</span></samp>’, ‘<samp><span class="samp">n</span></samp>’, ‘<samp><span class="samp">b</span></samp>’, ‘<samp><span class="samp">r</span></samp>’, ‘<samp><span class="samp">q</span></samp>’, or ‘<samp><span class="samp">k</span></samp>’),\r
+the next characters give the size in pixels, the\r
+following character indicates whether the piece is\r
+solid or outline (‘<samp><span class="samp">s</span></samp>’ or ‘<samp><span class="samp">o</span></samp>’),\r
+and the extension is ‘<samp><span class="samp">.bm</span></samp>’.\r
+For example, a solid 80x80 knight would be named <samp><span class="file">n80s.bm</span></samp>.\r
+The outline bitmaps are used only in monochrome mode.\r
+If bitmap pieces are compiled in and the bitmapDirectory is missing\r
+some files, the compiled in pieces are used instead.\r
+\r
+If the bitmapDirectory option is given,\r
+it is also possible to replace xboard's icons and menu checkmark,\r
+by supplying files named <samp><span class="file">icon_white.bm</span></samp>, <samp><span class="file">icon_black.bm</span></samp>, and\r
+<samp><span class="file">checkmark.bm</span></samp>.\r

- <p>In the shuffle variants, XBoard now does shuffle the pieces, although
-you can still do it by hand using Edit Position. Some variants are
-supported only in ICS mode, including bughouse, and
-kriegspiel. The winning/drawing conditions in crazyhouse (offboard
-interposition on mate), losers, suicide, giveaway, atomic, and 3check
-are not fully understood.
-Berolina and cylinder chess can only be played with legality testing off.
-In crazyhouse, XBoard now does keep
-track of offboard pieces. In shatranj it does implement the baring
-rule when mate detection is switched on.
-<br><dt>-boardHeight N<dd><a name="index-boardHeight_002c-option-357"></a>Allows you to set a non-standard number of board ranks in any variant.

-If the width is given as -1, the default width for the variant is used.
-With a non-standard width, the initial position will always be an empty board,
-as the usual opening array will not fit.
-Default: -1
-<br><dt>-holdingsSize N<dd><a name="index-holdingsSize_002c-option-359"></a>Allows you to set a non-standard size for the holdings in any variant.
-If the size is given as -1, the default holdings size for the variant is used.
-The first N piece types will go into the holdings on capture, and you will be
-able to drop them on the board in stead of making a normal move. If size equals 0,
-there will be no holdings.
-Default: -1
-<br><dt>-defaultFrcPosition N<dd><a name="index-defaultFrcPosition_002c-option-360"></a>Specifies the number of the opening position in shuffle games like Chess960.

-The letters before that will be PNBRQ and then a whole host of fairy pieces
-in an order that has not fully crystallized yet (currently FEACWMOHIJGDVSLU,
-F=Ferz, Elephant, A=Archbishop, C=Chancellor, W=Wazir, M=Commoner, O=Cannon,

-you are playing. If you have less than 44 characters in the string, the pieces
-not mentioned will get assigned a period, and you will not be able to distinguish
-them in FENs. You can also explicitly assign pieces a period, in which case they
-will not be counted in deciding which captured pieces can go into the holdings.
-A tilde '~' as a piece name does mean this piece is used to represent a promoted
-Pawn in crazyhouse-like games, i.e. on capture it turns back onto a Pawn.
-A '+' similarly indicates the piece is a shogi-style promoted piece, that should
-revert to its non-promoted version on capture (rather than to a Pawn).
-Note that promoted pieces are represented by pieces 11 further in the list.
-You should not have to use this option often: each variant has its own default

<h2 class="chapter">5 Firewalls</h2>
-<p>By default, XBoard communicates with an Internet Chess Server
-by opening a TCP socket directly from the machine it is running on
-to the ICS. If there is a firewall between your machine and the ICS,
-this won't work. Here are some recipes for getting around common
-kinds of firewalls using special options to XBoard.
-Important: See the paragraph in the below about extra echoes, in

<h2 class="chapter">7 Limitations and known bugs</h2>
-<p><a name="index-Limitations-393"></a><a name="index-Bugs-394"></a>There is no way for two people running copies of XBoard to play
-each other without going through an Internet Chess Server.
-
- <p>Under some circumstances, your ICS password may be echoed when you log on.
-
- <p>If you are connecting to the ICS by running telnet on an Internet
-provider or firewall host, you may find that each line you type is
-echoed back an extra time after you hit <Enter>. If your Internet
-provider is a Unix system, you can probably turn its echo off by
-typing <kbd>stty -echo</kbd> after you log in, and/or typing
-<^E><Enter> (Ctrl+E followed by the Enter key) to the telnet
-program after you have logged into ICS. It is a good idea to do this
-if you can, because the extra echo can occasionally confuse XBoard's
-parsing routines.
-
- <p>The game parser recognizes only algebraic notation.
-
- <p>Many of the following points used to be limitations in XBoard 4.2.7 and earlier,
-but are now fixed:
-The internal move legality tester in XBoard 4.3.xx does look at the game history,
-and is fully aware of castling or en-passant-capture rights. It permits castling with
-the king on the d file because this is possible in some "wild 1" games on ICS.
-The piece-drop menu does not check piece drops in bughouse to see if you actually hold
-the piece you are trying to drop. But this way of dropping pieces should be considered
-an obsolete feature, now that pieces can be dropped by dragging them from the holdings
-to the board. Anyway, if you would attempt an illegal move when using a chess engine or the ICS,
-WinBoard will accept the error message that comes back, undo the move, and let you try another.
-FEN positions saved by XBoard do include correct information about whether castling or
-en passant are legal, and also handle the 50-move counter.
-The mate detector does not understand that non-contact mate is not really mate in bughouse.
-The only problem this causes while playing is minor: a "#" (mate indicator) character will
-show up after a non-contact mating move in the move list. XBoard will not assume the game
-is over at that point, not even when the option Detect Mates is on.
-Edit Game mode always uses the rules of the selected variant,
-which can be a variant that uses piece drops.
-You can load and edit games that contain piece drops.
-The (obsolete) piece menus are not active,
-but you can perform piece drops by dragging pieces from the holdings.
-Edit Position mode does not allow you to edit the crazyhouse holdings properly.
-You cannot drag pieces to the holding, and using the popup menu to put pieces
-there does not adapt the holding counts and leads to an inconsistent state.
-Set up crazyhouse positions by loading / pasting a bFEN, from there you can set the holdings.
-Fischer Random castling is fully understood.
-You can enter castlings by dragging the King on top of your Rook.
-You can probably also play Fischer Random successfully on ICS by typing
-castling moves into the ICS Interaction window.
-
- <p>The menus may not work if your keyboard is in Caps Lock or Num Lock mode.
-This seems to be a problem with the Athena menu widget,
-not an XBoard bug.
-
- <p>Also see the ToDo file included with the distribution for many other
-possible bugs, limitations, and ideas for improvement that have been
-suggested.

<a name="Contributors"></a>
<h2 class="chapter">9 Authors and contributors</h2>
-<p><a name="index-Authors-400"></a><a name="index-Contributors-401"></a>
-Tim Mann has been responsible for XBoard versions 1.3 and beyond, and
-for WinBoard, a port of XBoard to Microsoft Win32 (Windows NT and
-Windows 95). H.G.Muller is responsible for version 4.3.
-
- <p>Mark Williams contributed the initial (WinBoard-only) implementation
-of many new features added to both XBoard and WinBoard in version
-4.1.0, including copy/paste, premove, icsAlarm, autoFlipView, training
-mode, auto raise, and blindfold. Ben Nye contributed X copy/paste
-code for XBoard.
-
- <p>Hugh Fisher added animated piece movement to XBoard, and Henrik Gram
-(henrikg@funcom.com) added it to WinBoard. Frank McIngvale added
-click/click moving, the Analysis modes, piece flashing, ZIICS import,
-and ICS text colorization to XBoard. Jochen Wiedmann ported XBoard to
-the Amiga, creating AmyBoard, and converted the documentation to
-texinfo. Elmar Bartel contributed the new piece bitmaps introduced in
-version 3.2. John Chanak contributed the initial implementation of
-ICS mode. The color scheme and the old 80x80 piece bitmaps were taken
-from Wayne Christopher's <code>XChess</code> program.
-
- <p>Chris Sears and Dan Sears wrote the original XBoard. They were
-responsible for versions 1.0 through 1.2.
-
- <p>Evan Welsh wrote <code>CMail</code>. Patrick Surry helped in designing,
-testing, and documenting CMail.
-
- <p>Allessandro Scotti added many elements to the user interface of WinBoard,
-including the board textures and font-based rendering, the evaluation-graph,
-move-history and engine-output window.

+Tim Mann has been responsible for XBoard versions 1.3 and beyond, and\r
+for WinBoard, a port of XBoard to Microsoft Win32 (Windows NT and\r
+Windows 95). H.G.Muller is responsible for version 4.3.\r
+\r
+Mark Williams contributed the initial (WinBoard-only) implementation\r
+of many new features added to both XBoard and WinBoard in version\r
+4.1.0, including copy/paste, premove, icsAlarm, autoFlipView, training\r
+mode, auto raise, and blindfold. Ben Nye contributed X copy/paste\r
+code for XBoard.\r
+\r
+Hugh Fisher added animated piece movement to XBoard, and Henrik Gram\r
+(henrikg@funcom.com) added it to WinBoard. Frank McIngvale added\r
+click/click moving, the Analysis modes, piece flashing, ZIICS import,\r
+and ICS text colorization to XBoard. Jochen Wiedmann ported XBoard to\r
+the Amiga, creating AmyBoard, and converted the documentation to\r
+texinfo. Elmar Bartel contributed the new piece bitmaps introduced in\r
+version 3.2. John Chanak contributed the initial implementation of\r
+ICS mode. The color scheme and the old 80x80 piece bitmaps were taken\r
+from Wayne Christopher's <code>XChess</code> program.\r
+\r
+Chris Sears and Dan Sears wrote the original XBoard. They were\r
+responsible for versions 1.0 through 1.2.\r
+\r
+Evan Welsh wrote <code>CMail</code>. Patrick Surry helped in designing,\r
+testing, and documenting CMail.\r
+\r
+Allessandro Scotti added many elements to the user interface of WinBoard, \r

-The main difference with micro-Max is that Fairy-Max loads its move-generator

-to implement unorthodox pieces.
-Fairy-Max can therefore play a lage number of variants, normal Chess being one of those.
-In addition it plas Knightmate, Capablanca and Gothic Chess, Shatranj, Courier Chess,
-Cylinder chess, Berolina Chess, while the user can easily define new variants.
