Learn How to Win Material: Discovered Attack
This puzzle shows a classic middlegame tactical refutation from the Queen's Gambit Declined Baltic Defense. White’s king is still in the center, and the position is overloaded with tactical pressure around the queen and bishop lines. Black can exploit a discovered attack idea: a forcing check first, then a follow-up that wins material by exposing White’s queen and disrupting coordination. The key lesson is that forcing moves often turn a slightly better position into a decisive material gain.
