Binary package “xboard” in ubuntu lucid

An X Window System Chess Board

 XBoard is a graphical chessboard that can serve as a user interface
 for GNU Chess, for the Internet Chess Server, or for electronic mail
 correspondence chess. XBoard can also be used by itself.
 XBoard uses the Helvetica font (located in the xfonts-75dpi and
 xfonts-100dpi packages) by default. However, other fonts can be
 specified via a command line option or an X resource.
