Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of tactical refutation built around a discovered attack and a forcing check. White’s queen is active on the sixth rank, the black king is slightly exposed, and the back rank is vulnerable because the d-file is open. The key idea is to use the queen to create a direct threat while also uncovering the rook’s pressure on the enemy queen and the loose bishop. When the opponent’s king is forced to respond, material falls quickly.
