Challenge: The deadly opening for Red in the 'Empty Cannon' formation - Xiangqi (Chinese Chess) 45c6 - Can you solve it?

When Red has a Rook on file 7 and Cannons on files 1,3,4, Black must be wary of the Rook's 'Threat'. Red's move of advancing the Horse on file 3 creates a double Horse threat, forcing Black to defend carefully.
