Heaven and Earth Cannons: The Decisive Breakthrough

Red utilizes the powerful 'Heaven and Earth Cannons' on the 7th file (g10 and g6) coordinated with the 8th-file Chariot to breach Black's central and flank defenses.

Tactical Analysis & Endgame Strategy

This endgame demonstrates the devastating power of the 'Heaven and Earth Cannons' configuration, where one Cannon controls the back rank and the other dominates the middle territory. By coordinating the Chariot on the h-file with these dual Cannons, Red exploits the structural weaknesses in Black's Advisor-Elephant defense. The key tactical lesson lies in utilizing the opponent's own pieces as cannon mounts (screens) and restricting the enemy King's escape routes, leading to an unstoppable mating net.
