Learn How to Exploit a Discovered Attack: London System
This middlegame puzzle comes from a Queen’s Pawn Game London System structure where White’s pieces are active and Black’s queen has overextended. The key idea is a discovered attack: one piece moves with tempo, revealing a stronger threat behind it. Here, the tactical point is not a mating net but a forcing sequence that wins material by exploiting loose pieces, king safety, and alignment on key diagonals. It is a classic example of how activity can outweigh raw material in classical chess.
