Yah. I've never had the benifit of a real jiu jitsu instructor teaching me how to work the ground game. In fact, everything I do is emulative, just me doing as a I see others do. The worst part of this is, even though I want to, the closest thing google finds for me is 3 hours away, and jiu jitsu or not, my work schedule doesn't allow that kind of thing.
So, the only option I can find right now is for me to learn as I learned so many things in life. Trial and error. Here's a video of me grappling with two ex-wrestlers (also my good friends). They were more than happy to roll, and help film this.
Bunch of really ametuerish mistakes sprinkled all throughout (on my part). All I know how to do (?) is an armbar and a rear choke, so I was a bit limited. I did use a bit of an arm torque type thing at about '6:42, but again, it's just something I saw, and then applied with my limited knowledge of body mechanics. There's the really great "omg he has back control wtf do I do?" moment at '7:20, but I'll just let you tear it apart yourselves.
