Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a pin and a forcing check. White’s queen is active, but the key idea is that one tactical move can expose a stronger line against the opposing queen and rook alignment. In positions like this, the best move is often not a direct capture, but a forcing move that creates a threat, wins tempo, and opens a file or diagonal for a heavier piece to invade.
