Learn How to Win the Queen: Defensive Move
This middlegame puzzle comes from the Englund Gambit Declined and shows how a defensive move can still be the most forcing choice. White is already better, but the real lesson is tactical: the black queen and knight are aggressively placed near the king, and one accurate capture can turn the attack into a winning combination. The position rewards calm calculation, not greed, because the best line uses checks and king safety to convert a decisive advantage.
