CastlingCastling is a defensive supermove. It is the only occasion when you move two pieces and count it as one move. Castling involves the king and one of the rooks. The player may castle either to the left with the left rook, or to the right with the right rook.
White and Black are ready to castle to their right. Red is ready to castle to Red's left. White castles to the right; Black does the same: .....1) King moves next to the rook. .....2) Rook moves to the opposite side of the king. Red castles to the left: King and rook swap positions. |
