Pirc Defense Bayonet Attack Puzzle (Rated 1137): Win Material — Fork Tactics
This middlegame puzzle comes from the Pirc Defense and shows how a single active queen can turn king safety into a decisive material gain. White’s queen invades with tempo, creating a fork that targets the exposed black king and a loose knight. The key idea is not a flashy mate, but a forcing sequence that wins material by keeping the king under pressure while the trapped piece has no good escape squares. It is a classic example of tactical refutation in classical chess.
