Introduction to GNU Backgammon
GNU Backgammon (gnubg) plays and analyses backgammon games and matches.
It is currently a work-in-progress. So far it is

positions for training and other
purposes,

be somewhat stronger than this when released. GNU Backgammon can be
played at numerous other online backgammon servers.
