Queens Pawn Game London System Puzzle (Rated 1140): Win Material — London System Tactic

This London System puzzle shows a classic middlegame tactical refutation where one active piece creates immediate threats against the enemy king and queen side coordination. The position is not about slow maneuvering: it is about recognizing a forcing sequence that wins material by exploiting an undefended knight, a vulnerable queen, and a fork created by the last move. In classical chess, these motifs often appear when development is uneven and the opponent’s pieces are overloaded.
