Challenge: The 'Red Chariot Exposed 2' Trap - A Lethal Mating Pattern in the Black General's Position - Can you solve it?

When the Red Chariot is exposed on File 2 and advances straight to Rank 4, the Black General must think quickly. If not prevented in time, it will be checkmated by the Black Horse on File 3 like a helpless victim. This is a classic 'double horse leg' formation where every move has lethal consequences.
