Challenge: The 'Empty Cannon Spear' Formation – Red's Advance Like a Deadly Dragon's Tongue, Black's Side Torn Apart - Can you solve it?

This is a **critical** formation in Vietnamese Chess, where Red's **Empty Cannon** threatens the very existence of Black's central piece. Without a **fierce counterattack**, the formation will **collapse within 3 moves**. This is where **patience and courage** decide the fate of both sides. Watch as Red must choose between a **direct, piercing advance** or a **retreat to reorganize**.
