Learn How to Win Material: Discovered Attack
This middlegame puzzle shows a classic attacking idea: use a forcing sacrifice to drag the king away from its shelter, then win material with a discovered attack on the queen. White’s active pieces and the weakened kingside make the tactic possible, even though Black appears materially ahead. The key is that the queen on d4 is overloaded and vulnerable once the king is forced to capture on h7. After the king moves, the exposed queen can be taken, turning the initiative into a decisive material gain.
