Queenside castling is a move in which the king steps two squares toward the a-file rook and that rook jumps over to the square the king crossed. Queenside castling is a move in which the king steps two squares toward the a-file rook and that rook jumps over to the square the king crossed, written 0-0-0 or O-O-O in notation. On the queenside the king travels from e1 to c1 (or e8 to c8) and the a-file rook finishes on d1 (or d8). It needs more room than [kingside castling](https://georgelichess.com/glossary/kingside-castling.md), because the [knight](https://georgelichess.com/glossary/knight.md), [bishop](https://georgelichess.com/glossary/bishop.md) and queen must all be out of the way: three empty [squares](https://georgelichess.com/glossary/square.md) lie between king and rook. The usual conditions apply, so neither piece may have moved before, the king may not castle out of check, and the king may not cross or land on an attacked square. One detail trips up strong club players too. The b-file square between the rook and its destination only has to be empty, and it is allowed to be attacked, because the king never stands on it. Queenside castling places the rook on the d-file at once, which is a useful post, and it leaves the king on c1 or c8 behind the a, b and c pawns. It is also the signature of sharp games in which each player castles on opposite wings and races to launch a [pawn storm](https://georgelichess.com/glossary/pawn-storm.md). Weigh that speed against the extra move of preparation it costs. Also called: long castling. It sits close to [Castling plan](https://georgelichess.com/glossary/castling-plan.md). A castling plan is a deliberate decision about when and on which side to castle, or whether to castle at all, based on the pawn structure, the opponent's setup and the attacks each side can launch. Also worth reading is [King](https://georgelichess.com/glossary/king.md). The king moves one square in any direction or castles, may never be left in check or moved into check, and is never captured, because the game ends when it is checkmated. It sits close to [Chess960](https://georgelichess.com/glossary/chess960.md). Chess960 is a variant that begins from one of 960 randomly chosen back-rank setups, with the king between the rooks and the bishops on opposite colors, and is otherwise played with the usual rules.
