Arm and Collar Choke when Opponent Tries to Escape the Mount (Fundamentals)

Professor Frederico Silva teaches how to get the arm and collar choke when the opponent tries to escape the mount by turning around. Frederico has the mount and the opponent tries to escape by turning around. Frederico lifts his leg up on the same side the opponent tries to roll. He stops the opponent while they are on the side and uses one hand to feed the lapel to the other hand. Frederico now pulls on the collar as he slides his other arm behind the head to get the arm and collar choke.
