Professor Frederico Silva shows how to get the clock choke after the opponent defends a double under pass attempt. Frederico tries a double under pass on the opponent but the opponent defends by rolling over the shoulder to the turtle position. Frederico follows him and stays on his side. He reaches over and under the opponent’s arm to control the lapel. He then uses that lapel control to feed it to the other hand. Frederico starts walking to the front so he can finish the clock choke.
