Learn How to Win Material: Discovered Attack
This puzzle comes from the Queen's Gambit Declined and shows how a forcing check can expose a tactical weakness in the opponent’s setup. White’s active pieces and the black queen’s advanced placement create a classic opening trap: one move can force a response that leaves the queen vulnerable to a tactical refutation. The key idea is that a discovered attack often works best when the opponent’s king is still uncoordinated and their queen is overextended.
