Challenge: Red Rook on File 4, Rank 10: A Subtle Trap in the 6/10 Position - Can you solve it?

When the Red Rook is on File 4, Rank 10, attacking, Black must be vigilant immediately. The Red Cannon on File 5, Rank 2 is setting a trap, and the Black Bishop on File 3, Rank 6 could be 'trapped' if not defended in time. The Black Rook on File 5, Rank 3 could also be 'pierced' if not anticipated.
