3 Part Technique - Don't hesitate to occupy the space under your opponent's arm with an underhook when you see it open for Over Under Control from Butterfly. Load up his base onto your butterfly hook and begin lifting him into the air as you direct his opposite shoulder to the mat with the overhook. If he posts his free leg out to prevent the Hook Sweep, keep your free foot posted close to your base and extend your leg to raise him up higher into the air. If this extra extension isn't enough to take his foot off the mat, place your foot on top of his knee and kick out the post. If his leg is too far forward to reach for this, enter into the X-Guard for the Unbalance Sweep.
