Queens Pawn Game London System Beginner Puzzle (Rated 1456): Win Material — Tactical Refutation
This middlegame puzzle is about recognizing a tactical refutation when the opponent’s last move leaves a piece vulnerable. White can use a forcing sequence to win material by first creating a check and then exploiting the loosened position. The key idea is that the king’s safety and piece coordination matter more than static material count when a direct tactic is available. Look for forcing moves that change the move order and expose a hanging piece.
