Challenge: Red General's Illegal Move: Rook Charges Straight, Horse Attacks All - Strategy to Defeat the Black Rook - Can you solve it?

Does the Red Rook at 5th file, 10th rank charge straight at the Black General at 6th file, 8th rank? Not quite. The Red Rook at 5th file takes a more sophisticated approach: 'Move the rook to 5th file, 9th rank, then move the rook from 5th file, 10th rank to cover it.' This creates a 'Rook Thrust' formation, forcing the Black Rook at 3rd file, 7th rank to defend. The Red Horse at 1st file, 9th rank attacks the Black Pawn at 7th file, 5th rank, creating a 'Double Horse Formation'. The Black General is exhausted and cannot escape the 'Mate Threat' from the Red side.
