Challenge: 'Black General on File 4, Rank 9' - The Secret of the Red-Blue River: "Winning Analysis from the Chessboard Perspective" - Can you solve it?

Stand before the chessboard when the Black General is on File 4, Rank 9 like a fire burning in the night, and the Red Chariot is on File 5, Rank 8 like a snake creeping close. This formation is not just a confrontation between horse and cannon, but also a lesson in balancing 'advance' and 'retreat', 'defense' and 'attack'. The board speaks to you: "*Who will decide the flow of the battle?*"
