this is how Kampmann arm triangled McFredries.

Thanks tony. I just got back from Jiu jitsu, and sure enough I got into side control. I can hold it for a long time now with the shoulder in the jaw and the same leg sprawled way out, so I had some time to think, and this was the solution that I came up with. It didnt quite work for me though. There must be some easier way to pry that elbow up over your head. Once it's there, it's pretty much bob's your uncle but I just couldnt, for the life of me, get that elbow up.
