Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Benko Gambit and shows how a tactical refutation can turn a stable-looking position into a winning material sequence. The key idea is a discovered attack: one piece moves with tempo, opening a line for a stronger attacker behind it. Here, the tactical shot also creates a fork and exposes loose pieces, so the defender is forced into a sequence that loses material. In classical chess, these motifs often decide the game before any endgame is reached.
