The gnuchess package contains the GNU chess program. By default,
GNU chess uses a curses text-based interface. Alternatively, GNU chess
can be used in conjunction with the xboard user interface and the X
Window System for play using a graphical chess board.
Install the gnuchess package if you would like to play chess on your
computer. If you'd like to use a graphical interface with GNU chess,
you'll also need to install the xboard package and the X Window System.
