Clock Choke when Opponent is in Turtle Position (Advanced)

Professor Andre Gois demonstrates a clock choke submission when the opponent is in the turtle position. He starts by securing side and grabbing the opponent's collar. Andre then feeds his arm under the opponent's neck and pulls up on the collar, applying pressure with his body weight to finish the choke. He also shows a variation where he uses his elbow to control the opponent's head and apply pressure for the submission.
