When any opponent moves a non-royal piece, you may “censor” that move: move the piece back, and let that player redo his move, but the piece that was censored may not move in the same direction that turn (this only applies to pieces who move only in one direction, so pieces such as knights are excluded from this restriction). Once you censor a move, you may not censor again until the end of your next turn.

First appearance: 12/5/06 (4th draft of rules).
