Professor Lucas Lepri teaches how to get the clock choke after he attempts to pass and the opponent tries to go for the single leg. Lucas is passing and the opponent starts to turn in and reaches for the single leg. Lucas immediately reaches under the neck to grip the opposite side collar. In this scenario, Lucas is not able to reach for the other collar or arm with his other hand. He instead, places his other elbow next to the neck and starts to walk to the side to finish the clock choke.
