Instead of the   Muay Thai clinch, you can use a single-collar tie by applying downward pressure to your opponent’s head  to force his weight down. As you opponent attempts to regain his base by bringing his head up  and his hips in, use the free hand to punch him in the face and keep on cutting angles . If your opponent manages to regain his base , grab his head with the other hand  and cut another angle  and continue throwing punches.

The idea is to continuously keep your opponent off balance  by cutting  angles and circling.
