French Defense Mate In 1 Puzzle (Rated 988): Spot Mate in 1 — Kingside Attack
This middlegame puzzle is a classic example of a kingside attack where the defender’s king is boxed in by its own pieces and pawns. The key idea is to look for forcing moves that exploit weak squares around the enemy king, especially when the queen and knight coordinate on the h-file. Even in a materially balanced position, king safety can outweigh everything else when the mating net is already in place.
