Strategy Puzzle (Rated 2096): Win the Endgame — Hanging Piece
This chess endgame is a classic example of how active rook play can convert a material edge into a clean win. White’s pieces are coordinated against loose black pawns and an exposed rook, so the key is to keep the opponent’s pieces tied down while improving the position of the king and minor pieces. In classical chess, the side with extra material should simplify when the opponent’s counterplay is limited.
