Cross Choke Using the Knuckles on the Neck from Closed Guard (Fundamentals)

Professor Lucas Lepri demonstrates a cross collar choke from the closed guard using one collar grip and his knuckles on the opponent's neck. He begins by trapping the opponent’s arm under his armpit, holding the cross-side collar and locking his legs higher on the opponent’s back to maintain the position. With his other hand, he grips the other collar and pushes his knuckles into the side of his opponent’s neck to complete the submission.
