Professor Lucas Lepri explains how to pass the De La Riva guard and establish side control. Lucas first grips the opponent's shin and then pushes the De La Riva hook down with his other hand. Next he points his knee outward before driving it over the opponent's knee and clubbing the head while switching his hips to pass the guard. Lucas keeps his head down, walks his body around to the north-south position, and releases his grip on the shin to block the opponent's hips before circling back and securing the side control position.
