King's Gambit Declined Queen's Knight Defense Puzzle (Rated 1070): Win Material — Pin Tactic
This middlegame puzzle is about using a pin to force a tactical simplification that wins material. Black’s active bishop creates immediate pressure on the white queen, and the follow-up exploits the fact that the queen cannot move freely without dropping a key piece. The position is a classic example of how a short tactical sequence can turn piece activity into a decisive advantage, especially when the opponent’s king safety is already compromised and several pieces are loosely coordinated.
