Grob Opening London Defense Puzzle (Rated 1658): Win Material — Tactical Refutation

This puzzle is a classic middlegame tactical refutation from the Grob Opening, where active piece placement matters more than raw material count. White’s pieces are coordinated around the kingside, and the key idea is to exploit a loose black queen-side structure and an exposed king. The position rewards forcing play: a direct capture opens lines, creates a skewer-like threat on the h-file, and turns Black’s active queen into a tactical liability.
