Learn How to Epaulette Mate: Mate in 1

This puzzle is a classic epaulette mate idea in a middlegame setting. The defending king is boxed in by its own pieces, and the mating move lands on a square that seals every escape route. Even though White is materially ahead, the real story is king safety: the black king has no flight squares and cannot be helped by nearby pieces. These are the kinds of tactical positions where a quiet-looking queen move can end the game immediately.
