Learn How to Spot Epaulette Mate: Mate in 1
This puzzle is a classic mate in 1 built around king safety and restricted escape squares. The key idea is an epaulette mate: the defending king is boxed in by its own pieces, so a direct queen check lands with no legal flight squares and no useful capture or block. In practical classical chess, these motifs often appear when heavy pieces coordinate on open lines and the enemy king is cramped by its own army.
