The Somersault Guillotine - Here's a pretty friggin sweet lookin way to choke someone to sleep.
Standing Submissions Part 2 - Here's a follow up to the "Fatal Self Defense" lesson in which I give you a bonus kick ass submission that starts from standing. I've tentatively started calling this the "Trav-aconda". Anyhow, this is an anaconda variation that I find to be virtually infallable any time I catch a front headlock position. This will choke your opponent to sleep in mere seconds.
This might be the most important partner drill in all of martial arts. I would spend a lot of time practicing this one if I were you... I know I have!
