inverted arm bar from guard

taught by professor gino. this is the closest video i could find. in prof. gino's variation, i post my far foot on the uke's hips. use a butterfly grip and press my forearm into his jaw, then rotate my whole body. close leg ends up high on his shoulder. need to move my neck closer to his wrist (away from his elbow). need a lot more practice on this one (hard to find his elbow with a gi on). only works if his posture is already somewhat broken.
