Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a forcing tactical refutation. White’s active knight creates a direct check while also uncovering pressure on the black queen and the queenside. The key idea is that one piece can serve two purposes at once: it gives check and opens a line for a stronger attacker behind it. When the opponent’s queen is overloaded and the king is exposed to follow-up checks, material can fall quickly.
