Professor Lucas Lepri demonstrates a De La Riva guard pass to north south position. Lucas first establishes a same side collar grip on the side where his leg is trapped by his opponent’s De La Riva hook. With his other hand, he pushes down the opponent’s hook and back steps. Lucas posts his hand on the mat while maintaining the collar grip and cuts his knee, then pivots and uses his shoulder on the opponent’s hip to maintain pressure as he transitions to the north south position.
