I hope this is where BJJ stuff goes.

"Ninja choke" is a bit over the top but you gotta call it something I guess. I found this technique by accident while sparring a few years ago. I just discovered this video tonight on one of the pages I follow on Facebook. I thought it was unique to me but really there is nothing new under the sun. One thing I learned from the video that I wasn't doing is trapping the foot. I kind of muscle through the application, so if I'm stacked up or are otherwise unable to sink it in quickly I just use it to sweep so I can get the mount or side control. With the foot trapped I think it'd be easier to hold them in place to lock down the choke. Any "constructive" positive or negative feedback is welcome, just no trolls please!
