Learn How to Spot Epaulette Mate: Mate in 1
This puzzle is a classic epaulette mate pattern in a sharp middlegame. The enemy king is boxed in by its own pieces, and the final attack works because the mating square is protected while escape squares are blocked. Positions like this often arise when a queen or other heavy piece invades the king zone and the defender’s pieces become part of the cage. The key idea is that checkmate can come from geometry, not just material advantage.
