Keys "s"=save "l"=load "b"=back once
Paul Movak, 1977. Dice start on move six. On this program, the roll will always match a unit which you have. (If playing with real dice, roll until it matches.) If you cannot make a move with such a unit, you lose. If you are in check, you do not roll.
These are simple illustrations rather than strong opponents.
