PRESS SPACE BAR FOR NEXT PAGE OR ESC TO EXIT HELP - page six THE EN PASSANT RULE AND DRAWS EN PASSANT Psion Chess recognises En Passant capture and will use it itself. En Passant capture can only occur when a player moves a pawn two squares forward to avoid capture by the opponent's pawn. The opponent can capture the pawn just as if it had only been moved one square instead of two. The option to capture the pawn en passant must be exercised immediately, before playing any other move, or it lapses. DRAW A draw is declared if stalemate occurs, if a position is repeated three times, or if no pawn is moved and no piece is taken during 50 consecutive moves.
