Professor Lucas Lepri shows how to do the paper cut choke from the north south position. Lucas has the opponent on the north south position and starts to isolate one of the arms. He reaches under the arm and grips the collar trapping the arm. Lucas now starts to move towards the side of the trapped arm turning his hips and places his knee against the arm. With the arm trapped, Lucas now reaches for the opposite collar and finishes with the paper cut choke.
