1 Part Technique - Frame against your attacker's face to release yourself from his Double Under Control, and pummel for and underhook of your own. If he leaves the space open, take the second underhook for a much more dominant Body Lock, rather than settling for Over Under Control and Hip Throw. Squeeze his hips in close to you while based perpendicular to his stance, and trip him straight backward, landing directly into the Mount Position. A common reaction at this point for an adversary who isn't well versed in grappling will try to get to his knees; Let him expose his back, and take the Rear Naked Choke to finish the confrontation.
