Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Indian Defense and shows how a discovered attack can turn a tactical detail into decisive material gain. White’s pieces are active, but one key piece is pinned and overloaded, creating a tactical target. Black can use the exposed alignment of the white king, queen, and rook to win material while keeping the initiative. The lesson is that in classical chess, one loose piece can become the start of a forcing combination.
