Red utilizes seamless Rook and Cannon coordination to exploit Black's exposed King and launch an unstoppable checkmate attack.
Red commands absolute spatial dominance with the Rook controlling the critical 7th rank and the Cannon setting up long-range threats. Black's King is isolated on the upper rank, while its defending Rook is immobilized and incapable of mounting a counter-defense. The endgame lesson emphasizes the classic Chariot-Cannon battery: leveraging the Rook to pin enemy forces and restrict escape squares while the Cannon strikes decisively from afar.
