Keys "s"=save "l"=load "b"=back once
E F Burtsev, 1956. Bishops can move once to an adjacent light square. Say, "Landing!"; Pawns past the fifth rank move and capture one square diagonally forward, one square orthogonally forward or to the side. Pawns promote to a rook, bishop, or knight that is already captured.
