Ruy Lopez Steinitz Defense Intermediate Puzzle (Rated 970): Win Material — Fork Tactics

This middlegame puzzle shows how a forcing check can create a tactical fork and win material in a position where king safety matters more than raw material count. Black’s active pieces coordinate against the white king in the center, and the key idea is to use tempo to drag the king into an awkward square. Once the king is displaced, the loose piece on the queenside becomes vulnerable, turning a checking move into a decisive material gain.
