Rook Endgame Puzzle (Rated 1370): Win a Rook Endgame — Crushing Technique

This chess endgame shows how active rook play can decide a seemingly simple position. Even with reduced material, the side with the more active rook can create decisive pressure by targeting loose pawns, cutting off the enemy king, and exploiting passed pawns. In classical chess, rook activity often matters more than raw material count. Here, the key idea is to force a simplification that leaves one side with a winning king-and-pawn ending and a promoted passer.
