Mate In 1 Puzzle (Rated 1012): Spot Epaulette Mate — Chess Endgame Puzzle

This chess endgame puzzle shows a classic mating net where the enemy king is boxed in by its own pieces and the final blow comes from a rook on an open line. In classical chess, these patterns often appear when rooks become active against a cramped king and there is no flight square left. The key idea is that the king’s own pieces can become a cage, turning a seemingly quiet rook move into immediate mate.
