Learn How to Win Material: Discovered Attack
This middlegame puzzle from the Mexican Defense shows how a discovered attack can turn a cramped position into a decisive material win.

The key lesson is that forcing moves often matter more than raw material: when one piece is overloaded and another is lined up behind it, a tactical refutation can appear immediately.
