Learn How to Win Material: Fork Tactics
This middlegame puzzle is about spotting a tactical refutation that wins material by creating a fork against the king and an exposed rook. The position rewards active piece play: one well-timed checking move forces the king into a narrow response, and that tempo lets the attacking side pick up a hanging piece. In practical classical chess, these motifs often arise when rooks invade the seventh rank and the opponent’s king lacks safe squares.
