Learn How to Win Material: Tactical Refutation
This puzzle comes from the Queen's Gambit Declined and shows how a middlegame advantage can turn into a decisive material gain when the opponent’s king safety is compromised. White’s active pieces create multiple tactical threats at once, especially against loose heavy pieces and an exposed back rank. The key idea is not a flashy attack for its own sake, but a forcing sequence that wins material by exploiting coordination problems and overloaded defenders.
