Challenge: Vietnamese General's Chess: The 'Collapsing River' Formation - The Mystery of the First Move - Can you solve it?
When the Red Horse enters at 5-6, the board trembles like a collapsing river. The Black Advisor at 4-10 and the Black General at 5-10 face a decisive battle. The Red Chariot at 3-6 and the Red Elephant at 7-5 create pressure, while the Black Pawn at 1-5 and the Black Horse at 1-4 prepare for a counterattack. Is this the 'collapsing river' formation or just a move by the crossed horses?
