Learn How to Win Material: Discovered Attack
This middlegame puzzle from the Scandinavian Defense shows how a tactical refutation can turn a small edge into decisive material gain. White’s pieces are active, and the key idea is a discovered attack: one piece moves with tempo while uncovering pressure on a more valuable target. The position also features a pin and a hanging piece, so the defender is overloaded and unable to solve every threat at once. It is a classic example of how classical chess tactics punish loose coordination.
