Learn How to Win Material: Tactical Refutation
This middlegame puzzle is about spotting a tactical refutation when a piece is overextended and vulnerable to capture. White’s active rook looks powerful, but it is actually exposed to a forcing sequence that wins material. The key idea is removal of the defender: once the loose piece is taken, the follow-up creates a direct threat against another target. In classical chess, these short combinations often decide the game by turning activity into a material deficit for the side that overreached.
