Keys "s"=save "l"=load "b"=back once
Chris Taylor, 1979. Capture is by checkmating a unit, i.e., setting up a position in which the piece could not be rescued according to the rules of FIDE chess. Placing one's own king in check is legal. Win by checkmating the opponent's king.
NOTE: Right now, there's a bug that may prevent the human player
from recognizing a checkmate, and an extra win may be assigned. I hope
to be able to fix this.
These are simple illustrations rather than strong opponents.
