Challenge: Black Chariot on File 10 – The Iron Chain Trap: "When a Single Piece Awakens the Battle of the MacArthur Plan" - Can you solve it?

This is not a confrontation between two armies, but **a battle of one against many**, where the Black Chariot on File 10 – the last surviving piece of the Black side – becomes **a lone iron wall** before the Red front. This is not just a chess position, but **a reenactment of the Battle of Bach Dang**: "When the enemy crosses the river, we must use **a little land** to make them drown in a sea of fire. Learn how to turn weakness into strength with **cannon strikes, chariot thrusts, and determination like General Tran Quoc Tuan."
