Learn How to Win Material: Pin Tactic
This middlegame puzzle is a classic example of a tactical refutation built around a pin and a hanging piece. White’s rook pressure on the f-file creates a direct tactical target, while Black’s active rook and bishop look dangerous but are overextended. The key idea is to notice when a defended-looking piece is actually pinned to a more valuable target, allowing a forcing sequence that wins material and shifts the balance immediately.
