Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a tactical refutation built around king safety and piece coordination. White’s attack works because the black king is exposed to a forcing check while the queen is overloaded and vulnerable to a follow-up capture. The key idea is not a flashy mate, but a decisive material win created by forcing the king to respond and then taking advantage of the loose queen in the center. It is a strong example of a crushing discovered attack.
