Mate In 1 Intermediate Puzzle (Rated 875): Spot a Mate in 1 — Chess Endgame

This chess endgame puzzle is a pure tactical finish: White’s king is boxed in, and Black’s queen has a direct mating route. In positions like this, material count matters far less than king safety. The key idea is to scan for forcing moves first, especially checks that also control escape squares. Even when the position looks quiet, a single tactical shot can end the game immediately if the defending king has no flight squares and no piece can interpose or capture the attacker.
