Mate In 1 Puzzle (Rated 860): Spot Mate in 1 — King Safety

This puzzle is a classic middlegame king-safety finish: one side’s king is boxed in, the escape squares are covered, and a forcing queen move ends the game immediately. In classical chess, these patterns often appear after a kingside attack has stripped away the pawn shield. The key lesson is that material can be irrelevant when the enemy king is exposed and your pieces already control the critical squares around it.
