Learn How to Win Material: Discovered Attack
This classical chess puzzle comes from the Four Knights Game and shows how a discovered attack can turn a middlegame into a decisive material win. White’s pieces are coordinated around the enemy king and queen, and one forcing bishop move creates a direct tactical threat while also exposing a major target behind it. The key idea is that a seemingly simple check can be more than a check: it can uncover a stronger attack on a valuable piece.
