Learn How to Spot Epaulette Mate: Mate in 1
This puzzle is a classic example of a mating net built around king safety rather than material. Even though one side is down heavily in material, the active queen and rook coordinate to trap the enemy king with no escape squares. The key idea is epaulette mate: the king is boxed in by its own pieces and cannot flee because the checking piece controls the final escape route. In practical classical chess, these patterns often appear in sharp middlegame or endgame positions.
