Mate In 1 Puzzle (Rated 944): Spot Mate in 1 — Chess Endgame Puzzle

This puzzle is a classic chess endgame-style mating finish: one precise move ends the game immediately. The key idea is to recognize when the enemy king has no safe squares, no blocking piece, and no capture that can remove the threat. In positions like this, material count matters far less than king safety. Even in classical chess, a quiet-looking board can hide a forced checkmate if the queen or another major piece has access to a decisive square.
