Queen-side castling or long castling, a move in chess consisting of moving the king two squares toward the queen-side rook on the same rank and then moving said rook to the square the king passed over. The move cannot be performed if the player is in check, if the king or the rook in question has already moved. Queen-side castling is notated O-O-O.
