French Defense Exchange Variation Queenside Attack Puzzle (Rated 1002): Spot Mate in 1 — Queenside Attack

This middlegame puzzle is a classic example of a mating net built around king safety and piece coordination. White’s position is under pressure, but the key idea is that Black’s queen has an immediate checkmate on the queenside because the white king’s escape squares are completely covered. In classical chess, these patterns often appear when a queen invades the second rank and the defending pieces are too tied up to respond.
