Learn How to Spot Epaulette Mate: Ruy Lopez Tactics
This puzzle comes from a sharp middlegame in the Ruy Lopez Classical Variation, where the black king is boxed in by its own pieces and the queen has a direct mating route. The key idea is epaulette mate: a king is trapped because the squares beside it are occupied or controlled, leaving no escape. In positions like this, even a material lead matters less than immediate king safety, and the right forcing move ends the game at once.
