Learn How to Win Material: Discovered Attack
This middlegame puzzle is built around a discovered attack: one piece moves with tempo, uncovering a stronger line of attack from another piece. The key idea is that the apparent target is not the real prize; the hidden attack creates a tactical refutation that wins material. In classical chess, these motifs often appear when the queen, bishop, or rook is lined up against a vulnerable piece or king zone, and a forcing check or capture opens the position at exactly the right moment.
