Nimzo Larsen Attack Graz Attack Puzzle (Rated 1667): Win the Queen — Tactical Refutation

This middlegame puzzle is about recognizing when an active queen can create a decisive material gain by targeting loose pieces and an exposed king. White’s king is still in the center, while Black’s pieces are coordinated enough to exploit the g2 and h1 area. The key idea is not a flashy checkmate, but a forcing sequence that wins material by using threats against the queen, rook, and knight. In classical chess, these tactical refutations often decide the game immediately.
