Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Queen's Gambit Declined and shows how a seemingly active queen and bishop can be used to force a tactical refutation. White is not looking for a mating attack here, but for a clean way to win material by exploiting pins, skewers, and a trapped piece. The key idea is to notice when the opponent’s last move overextends and leaves their queen, bishop, or knight vulnerable to a forcing sequence.
