Keys "s"=save "l"=load "b"=back once
Jason Shields, 1995. Capturing a unit destroys both units, the square, and all adjacent units. There is no en passant capturing.
In May 2002, I fixed an error, and the machine now recognzies that a square has been destroyed when considering whether a capture will place one's king in check. Sorry for any inconvenience.
These are simple illustrations rather than strong opponents.
