Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle is a classic mating pattern in the middlegame, where the attacking queen lands on a square that seals the king’s escape and delivers immediate checkmate. The key idea is that the defending king is boxed in by its own pieces and pawns, so one forcing move ends the game at once. In classical chess, these patterns often appear when king safety is weak and the opponent’s pieces are overloaded or poorly coordinated.
