Learn How to Win Material: Discovered Attack
This middlegame puzzle is built around a discovered attack, where one piece moves with tempo and uncovers a stronger threat behind it. The key idea is that the active black knight creates a direct check while also exposing the bishop’s line toward the white queen. In practical classical chess, these positions often arise when a pinned or overloaded piece cannot meet both threats at once, leading to a decisive material gain rather than a simple trade.
