Learn How to Win a Piece: Tactical Refutation
This middlegame puzzle from the Sicilian Defense Marshall Counterattack shows how a single tactical shot can overturn a seemingly active position. White’s king safety is compromised, and Black’s pieces coordinate against loose targets around the king and center. The key idea is a tactical refutation that wins material by forcing the king into an awkward square and then exploiting the exposed back line and hanging pieces. It is a classic example of converting activity into a decisive material gain.
