Challenge: The 'Black Rook on File 5' Trap - A Subtle Defense for the Red General in the 1/10 Opening - Can you solve it?

When the Black Rooks on File 5 and File 9 intersect on Rank 10, the Red General must be cautious. The Black Rooks can create a false 'double horse leg' to attack the Red General. The Red Horse on File 6, Rank 5 needs to be defended carefully.
