Queens Gambit Declined Miles Variation Puzzle (Rated 1139): Win Material — Crushing Fork

This middlegame puzzle is about using active queen play to create a forcing check that also attacks key loose pieces. White’s pieces are coordinated around the center, while Black’s king safety is compromised and several defenders are tied down by pins and pressure on the c6-knight. The best tactic is not a slow improvement move, but a direct forcing sequence that wins material by exploiting the king’s limited escape squares and the overloaded defense of the queenside.
