Rook Endgame Puzzle (Rated 1228): Win a Chess Endgame — Rook Pin Tactic

This chess endgame is a classic example of how active rook placement can turn a seemingly equal position into a winning one. The key idea is that a pinned pawn becomes tactically vulnerable when it is tied to the king, especially in a rook endgame where every tempo matters. White’s rook activity creates a direct tactical problem for Black’s king and pawn structure, while the advanced passed pawn on the queenside adds extra pressure and limits counterplay.
