Queens Gambit Accepted Kingside Attack Puzzle (Rated 841): Mate in 1 — Queens Gambit Accepted

This classical chess puzzle comes from the Queens Gambit Accepted and shows how a well-timed kingside attack can end the game instantly. The position is a pure mate in 1, so the main lesson is pattern recognition: when the enemy king has limited escape squares and the queen can reach the final attacking square, tactical awareness matters more than material. Even in a middlegame where Black may be up material, king safety can override everything.
