About Castling
Castling is the only move that shifts two pieces at once, tucking the king into safety while activating a rook. In tactics it appears in surprising ways: castling into an attack, castling with tempo to unleash a rook on an open file, or exploiting an opponent who can no longer castle. Knowing exactly when castling is legal — and when a single check or rook move forfeits the right forever — is worth real points. These {count} castling puzzles highlight positions where the special move itself is the key to the combination.
Frequently asked questions
What are the rules for castling?
Neither the king nor the chosen rook may have moved, the squares between them must be empty, and the king cannot start in, pass through, or land on check.
Can castling be a tactic?
Yes. Castling can bring a rook to an open file with tempo, connect an attack, or reach safety just in time, deciding the game.
When do you lose the right to castle?
Permanently once the king moves, and on a given side once that rook moves. You also cannot castle while in check or through an attacked square.
