Robson starts from the full guard, controlling both sleeve grips, and opens his guard to escape his hips. With his foot in the hip, he pulls the same side arm, making sure his opponent can't make a grip. Robson now brings his other foot inside the legs to make the first butterfly hook, and at the same time, sits up, swimming his arm underneath the armpit. Now he takes the foot off the hip and puts his leg underneath his opponent's legs, as he shoves the sleeve grip arm between the legs, and lifts his opponent with his hook. Now his opponent is off balance, and Robson can start to work his butterfly techniques.
