Learn How to Win Material: Discovered Attack
This French Defense Advance Variation puzzle is a classic middlegame tactical refutation built around a discovered attack. White’s active bishop and rook coordination create a forcing sequence that exploits the black king’s vulnerable placement and the overloaded queen-side defenders. The key idea is not a quiet improvement, but a tactical shot that wins material by forcing the king to recapture and then opening a line for the rook to attack a major piece. It is a strong example of how activity can outweigh raw material.
