Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle is a classic mate in 1 that highlights a rare but beautiful mating pattern often called swallowtail mate. The key idea is that the enemy king is boxed in by its own pieces and pawns, leaving only one square for the attacking queen to deliver a decisive checkmate. Even in a materially imbalanced middlegame or chess endgame, king safety can outweigh everything else when the mating net is already complete.
