Learn How to Spot Epaulette Mate: Mate in 1

This puzzle is a classic mate in 1 built around a cramped king and its own pieces blocking escape squares. In middlegame positions like this, the winning idea is often not material gain but a direct mating net where the queen lands on a key square and the enemy king has no flight squares. The surrounding pieces act like a cage, and the final checkmate works because every defense is already covered or impossible.
