Pins In Rook Endgames Puzzle: Pin — Rook Endgame
In this rook endgame, the key idea is to coordinate an active rook with a dangerous passed pawn. The advanced pawn restricts the defender and forces the opposing rook into a passive role. Once the attacking rook improves its position, the defensive piece can become tied to promotion duties and vulnerable to a pin or skewer. This is a classic example of how rook activity, king restriction, and promotion threats can combine into a decisive material advantage.
