+
+You can also tell the engine to exclude some moves from analysis.
+(Engines that do not support the exclude-moves feature will

+The general way to do this is to play the move you want to exclude

+When you use drag-drop moving, the piece you grab with a double click
+will also remain on its square, to show you that you are not really
+making the move, but just forbid it from the current position.

+before or after the settingsFile options.

+@item -defaultMatchGames n
+@cindex defaultMatchGames, option

+@item -matchPause n
+@cindex matchPause, option
+Specifies the duration of the pause between two games of a match or tournament
+between engines as n milliseconds.
+Especially engines that do not support ping need this option,

-@cindex bm, option
-@cindex bitmapDirectory, option
-@cindex pixmap, option
-@cindex pixmapDirectory, option
-These options control what piece images xboard uses. The XBoard
-distribution includes one set of pixmap pieces in xpm format, in the
-directory @file{pixmaps}, and one set of bitmap pieces in xbm format,
-in the directory @file{bitmaps}. 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.
-
-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} option, or a bitmap piece set can be selected
-with the @code{bitmapDirectory} option.
-
-If XBoard is configured and compiled on a system that does not include
-libXpm (or the @code{--disable-xpm} 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} option.
-Or again, a different bitmap piece set can be selected with the
-@code{bitmapDirectory} option.
-
-Files in the @code{bitmapDirectory} must be named as follows:
-The first character of a piece bitmap name gives the piece it
-represents (@samp{p}, @samp{n}, @samp{b}, @samp{r}, @samp{q}, or @samp{k}),
-the next characters give the size in pixels, the
-following character indicates whether the piece is
-solid or outline (@samp{s} or @samp{o}),
-and the extension is @samp{.bm}.
-For example, a solid 80x80 knight would be named @file{n80s.bm}.
-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.
-
-If the bitmapDirectory option is given,
-it is also possible to replace xboard's icons and menu checkmark,
-by supplying files named @file{icon_white.bm}, @file{icon_black.bm}, and
-@file{checkmark.bm}.
-
-For more information about pixmap pieces and how to get additional

+When neither of these is found (or no valid directory is specified)
+XBoard will use the svg piece that was installed with it

+The @code{view} option will be used by desktop associations with

+used to configure the exact mode XBoard will start in when it
+should act on such a file (e.g. in -ncp mode, or analyzing
+with your favorite engine). The options are also automatically
+appended when Board is invoked with a single argument not being

+Default: "-ncp -engineOutputUp false -saveSettingsOnExit false".
+@item -tourneyOptions string
+@cindex tourneyOptions, option
+When XBoard is invoked with a single argument that is a file

Default: ""
+@item -pieceNickNames string
+@cindex pieceNickNames, option
+The characters in the string are interpreted the same way as in the
+@code{pieceToCharTable} option. But on input, piece-ID letters are
+first looked up in the nicknames, and only if not defined there,
+in the normal pieceToCharTable. This allows you to have two letters

+The side-to-move field in a FEN will be first matched against the letters
