Learn How to Refute a Pin: Tactical Refutation
This middlegame puzzle comes from the Queen's Gambit Declined and shows how king safety can outweigh material. White’s bishop has invaded the kingside, but that piece is overextended and vulnerable. Black’s best response is a forcing tactical refutation that wins material by exploiting the exposed king and the loose bishop. The key lesson is that active-looking attacks can fail when the defender has a precise capture and a follow-up check to neutralize the initiative.
