Me goin against my lil bro in a light spar match, no face shots attempting submissions. One thing too my lil brother Corey is stronger than I am. I beat him with an armbar i learned from a blackbelt in Karate where from full mount u use your weight on your opponents arms and bounce to your opponents side and take control of the arm. it happens to fast that your opponent cant react in time and stop the submission from being locked
