Dutch Defense Korchnoi Attack Puzzle (Rated 1205): Win Material — Fork Tactic

This middlegame puzzle is about turning king safety into a decisive material gain. White’s queen activity creates a forcing sequence that checks the enemy king and then wins a key piece, while the opponent’s bishop is left overloaded and vulnerable. The position rewards accurate calculation over slow maneuvering: once the forcing move lands, the follow-up is about collecting material before the defense can reorganize. It’s a classic example of how active pieces can convert pressure into a concrete advantage.
