Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack, where one move opens a line for a stronger piece while creating an immediate tactical threat. The key idea is that the attacked piece is not the real story; the hidden line behind it is. In positions like this, a forcing check can also expose loose material and turn a seemingly active position into a winning combination. The result is decisive material gain rather than a mating attack.
