Trapped Piece Beginner Puzzle (Rated 1157): Win Material — Chess Endgame Tactic

This chess endgame puzzle is built around a classic winning combination: a pawn break that opens lines, forces a capture, and then removes the defender of a key piece. White has active pawns, strong kingside pressure, and a trapped black rook that is short of safe squares. The position rewards accurate calculation and patience, because the tactical idea is not a direct checkmate but a clean material win that leaves White with a decisive advantage.
