Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle is a classic mating finish in a sharp endgame-like setting, where the attacking side uses coordinated queen and rook pressure to trap the enemy king. The key idea is a swallowtail mate pattern: the king’s escape squares are controlled, and the mating piece lands on a square that cannot be captured or blocked. Even though the material is balanced, king safety is completely decisive, so the correct move ends the game immediately.
