Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic discovered attack: one piece steps aside to unleash a stronger line of attack from another piece. The key idea is that the move also creates a forcing check, so the opponent is dragged into a narrow response while a major target becomes exposed. In positions like this, tactical motifs such as hanging pieces, pins, and x-ray pressure often combine to produce a decisive material gain rather than a slow strategic squeeze.
