Professor Lucas Lepri demonstrates a technique for passing an opponent’s reverse De La Riva guard when the opponent is able to trap Lucas’ free leg in an attempt to transition to one leg X-Guard. As soon as the opponent underhooks the leg, Lucas puts that knee on the floor and windshield wipers his foot to trap the opponent’s leg. Lucas then shifts his eight to underhook the opponent’s leg. He completes the pass to side control by applying a cross face with the other arm and falling to his hip on the side opposite the leg he has underhooked.
