Learn How to Win Material: Tactical Refutation
This middlegame puzzle from the Queen's Gambit Accepted shows how a hanging piece can decide the game when the king is still exposed. White’s queen is active near the enemy king, and Black’s back rank and loose pieces create a tactical target. The key idea is to notice that a high-value piece can be won with tempo, forcing the opponent into a defensive response that still leaves major material vulnerable. It is a classic example of tactical refutation and decisive material gain.
