Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Scandinavian Defense and shows how a discovered attack can turn a normal-looking position into a decisive tactical refutation. White’s pieces are active, but the king safety imbalance and loose coordination give Black a forcing way to win material. The key idea is that one piece can move with tempo, creating a direct threat from a hidden attacker behind it. In classical chess, these short tactical sequences often decide the game before any long-term plan matters.
