Learn How to Win Material: Tactical Refutation
This middlegame puzzle from the Center Game Berger Variation is about recognizing a tactical refutation when the opponent’s queen becomes overextended. White has active pieces and pressure on the d-file, but Black can turn the tables by exploiting the loose rook and the exposed queen. The key idea is that forcing exchanges can uncover a hidden attack on a major piece, converting activity into decisive material gain rather than a mere positional edge.
