Cochrane Gambit Puzzle (Rated 1254): Win Material — Fork Tactics

This middlegame puzzle comes from the Petrovs Defense Cochrane Gambit and centers on a forcing queen check that creates a fork on the black king and a loose rook. White’s active queen and bishop pressure the king side while Black’s rook on e4 is overextended and vulnerable. The key idea is to use king safety and piece coordination to win material, not to chase a speculative attack. In classical chess, forcing moves often expose hanging pieces and turn a small initiative into a decisive advantage.
