Learn How to Win Material: Discovered Attack
This Horwitz Defense puzzle shows how a forcing check can expose a tactical weakness in the enemy camp. The key idea is a discovered attack: one piece moves with tempo, uncovering another attacker and creating a direct threat against a valuable target. Here, the position is especially sensitive because the black queen is active but overextended, and White can use the check to force a response that leaves Black unable to keep everything protected. It is a classic middlegame pattern where activity beats raw material.
