Challenge: Xiangqi (Chinese Chess) Strategy: Black Chariot Blockade, Red Cannon Counterattack - A Master's Tactics Like the Xich Bi Battle of Bach Dang - Can you solve it?

Black Chariot on File 5 Rank 6 blockades Red Cannon on File 5 Rank 7, similar to General Tran Hung Dao's strategy against the Thoat Ly army. The Red Cannon must choose between 'Advance' or 'Retreat' to escape capture, much like how General Le Loi had to decide between 'Attack' or 'Counterattack' when besieged at Dong Kinh Gate.
