Keys "s"=save "l"=load "b"=back once
A 3-D chess variant from Texas Educational Devices, 1966, for psychological experiments. Knights move one square diagonally in any direction. Kings cannot change level. I have the fifty move rule kick in if there have been no pawn moves on the same level.
These are simple illustrations rather than strong opponents.
