London System Poisoned Pawn Variation Puzzle (Rated 1103): Win Material — London System Tactic

This London System puzzle shows how a calm opening can turn into a sharp middlegame when the enemy king is exposed and key pieces are loose. White’s queen and bishop coordinate to create forcing checks that win material, while Black’s kingside structure is too fragile to absorb the pressure. The tactical idea is not a random sacrifice, but a forcing sequence that exploits an undefended piece and the king’s lack of shelter.
