Learn How to Win Material: Discovered Attack
This puzzle comes from the Nimzowitsch Defense and shows a classic middlegame tactical refutation. Black’s queen activity creates a forcing sequence that exposes White’s king and overworked pieces, turning a seemingly normal position into a decisive material win. The key idea is a discovered attack: one piece moves with tempo, uncovering pressure on a more valuable target while also keeping the initiative. In practical classical chess, these tactics often decide games before the endgame begins.
