Learn How to Spot Mate in 1: Swallowtail Mate
This puzzle is a classic middlegame mating pattern where the enemy king is exposed and the final attack lands with a single forcing move. The key idea is that the queen can use open lines and the king’s limited escape squares to deliver immediate checkmate. Even when material is slightly behind, king safety becomes the deciding factor. In classical chess, these tactical finishes often come from active piece placement and a weakened pawn shield around the king.
