Petrovs Defense Nimzowitsch Attack Puzzle (Rated 1274): Win Material — Tactical Refutation
This middlegame puzzle is all about a tactical refutation that turns an active position into a decisive material win. White’s pieces are coordinated against the black queen, bishop, and rook structure, and the key idea is to exploit the overloaded defender on the back rank and the loose bishop on f3. The position rewards players who look for forcing moves first, especially captures that create a skewer or expose a pinned piece.
