From www.Chewjitsu.net:
In this video I demonstrate a technique that I’ve used a ton over the years. My student’s have also had a lot of success with it. I’ve been able to hit it against BJJ players, Wrestlers and Judokas successfully. Throw it in with your current takedown techniques and see how it works for you.
What I like about this technique is even if we fail, most often you end up in butterfly guard with decent grips ready to attack.
