Learn How to Win Material: Discovered Attack
This middlegame puzzle centers on a discovered attack: one piece moves to create a new line of fire for another, while also winning material. The key idea is that the active knight jump does more than attack a target directly; it clears the way for a bishop to become the real tactical force. Black’s pinned pieces and loose king-side coordination make the tactic work, turning a seemingly normal position into a decisive material gain.
