Challenge: Red's Broken Formation: "The Rook on File 9 Pierces, Cannon on File 5 is Empty – A Brutal Opening for Beginners" - Can you solve it?

This is a **blocking** formation where Red misses the opportunity to break Black's formation with unexpected moves. The rook on file 9 not only attacks but also *pierces* into the opponent's defensive line, while the cannon on file 5 creates an 'empty cannon' that could drastically alter the board. Seeing this, what would you think?
