Kings Gambit Declined Keene Defense Puzzle (Rated 1426): Fork — Winning Material
This middlegame puzzle is a classic example of a tactical fork that wins material and turns a sharp position into a decisive advantage. White’s active knight jumps into the enemy camp with check, forcing the king to respond while also creating a threat against a valuable piece. That kind of dual-purpose move is the heart of many classical chess puzzles: one forcing idea, two targets, and no clean defense. The position rewards calculation over slow maneuvering.
