Learn How to Swallowtail Mate: Mate in 1
This chess endgame puzzle is a classic mate in 1 that highlights a swallowtail mate pattern: the enemy king is boxed in by its own pieces and pawns, while your queen delivers the final check from a square that cannot be captured or blocked. In classical chess, these short tactical finishes often appear when king safety has collapsed and the defender’s pieces are overloaded. Even in a quiet-looking endgame, one precise move can end the game immediately.
