Red utilizes double stacked cannons on the central file alongside an advanced pawn to immobilize the enemy palace and force checkmate.
Red demonstrates absolute tactical dominance by forming the lethal Stacked Cannons (Trùng Pháo) configuration along the central file. The advanced Red Pawn restricts the Black King and Advisors' escape routes, turning Black's central Rook into a helpless screen that Red exploits. The coordinated cannons create an unstoppable battery that shatters Black's final palace barriers. This endgame highlights the destructive power of central cannon alignment, showing that stacked cannons often render all defender resistance futile.
