Learn How to Spot Mate in 1: Alekhine Defense
This middlegame puzzle comes from the Alekhine Defense Four Pawns Attack and shows how quickly a king can be punished when the pieces are active and the escape squares are cut off. Even in a position where White is materially ahead, the side to move can still have a forced mating finish if the enemy king is boxed in by its own pieces and pawns. The key lesson is that tactical opportunities can override material, especially when the king lacks safe flight squares.
