Learn How to Mate in 2: Epaulette Mate
This puzzle is a classic forcing finish where the attacking side uses a discovered check to drive the king onto a worse square, then a rook delivers the final net. The key idea is that the defender’s own pieces and king become part of the mating pattern, creating an epaulette-style trap. In a middlegame, these motifs often appear when the enemy king is boxed in by its own pieces and the back rank or h-file is vulnerable.
