Black falls into a self-defeating 'empty cannon' trap, allowing Red to capitalize and secure victory.
This position highlights the peril of placing a Cannon in an unsupported 'empty' file. Black's critical error of moving the Cannon to the 10th file opens a direct avenue for Red's attack. The crucial endgame lesson is to always ensure the safety and coordination of key pieces, especially the Cannon, avoiding risky moves that can lead to immediate defeat.
