Challenge: Red Chariot Advances on File 4: A Trap for the Black Horse in a Tense Position - Can you solve it?

The board is cramped like a birdcage, but the Red Chariot advancing to file 4 rank 7 is so dangerous that it could immediately 'checkmate' the Black Horse on file 6 rank 8. The Red Cannon on file 4 rank 2 is setting a trap for the Black Pawn, while the Red Advisor on file 5 rank 2 prepares to 'break' into the Black Advisor on file 4 rank 8. This is a position only high-level players can overcome!
