Zipper Choke from Back Control (Fundamentals)

Professor Lucas Lepri teaches how to finish a collar choke from the back. Lucas goes into detail on how to control the opponent from the back. He then shows how to slide one hand onto the collar and up to the neck. The other hand grips the opposite collar. Lucas now comes up on his elbow and pulls on the collar to get the zipper choke. If the opponent attempts to escape, Lucas scissors his legs and comes up on the opponent. This allows him to pull the opponent to the other side where he can finish the submission.
