Learn How to Use a Discovered Attack: Decisive Material Gain
This middlegame puzzle is a classic example of a discovered attack, where moving one piece creates a direct threat from another.

Because the enemy king is exposed and the queen is overloaded, the combination forces a favorable sequence that wins material and leaves White clearly better.
