Red is in a dominant position with 'Cannon on the 8th file' and 'Chariot on the 7th file', like two sharp daggers piercing into Black's center. This position is not just a battle between 'Black Advisor on the 4-5 files' and 'Red Advisor on the 5-4 files', but also a fierce confrontation between 'Black Elephant on the 3-5 files' and 'Red Pawn on the 9th file'. Let AI Master analyze how to **force the opponent to retreat** with moves like 'Cannon horizontal attack', 'Chariot horizontal thrust', and how to **counterattack brilliantly** when Black tries to restore balance with 'Horse on the 2nd file' or 'Elephant on the 5th file'.
