Cool click. Congratulations. The good ol rear naked choke, (also known as the RLVR-Rear Lateral Vascular Restraint-or "cop choke" for our friends not as well versed in jiu jitsu). A tried and true technique. An oldie but a goodie. And for our homophobic friends out there, it's called the naked choke because it's one of the few jiu jitsu chokes that in no way utilizes the gi. I've used it a few times, but I actually once choked an SOB out right there in the gym because he wouldn't tap. It was kind of unsettling when I realized the bastard was unconciouss under me. Not fun. I still think there's a lot to be said for a good old fashioned armbar.
