1. Notice how I control his right arm with my legs so he can not escape easily or strike from the bottom.

2. While his arm is trapped, he cannot defend punches to the face with that hand, this can be devastating and actually end the fight by itself, but I will count on him being skilled and strong.

3. He uses his left hand to defend, this gives me the opening I was looking for and I take it.

4. I press his left wrist to the floor with my left hand, keeping my right arm under his left. I switch my base and go for the shoulder lock.
