We teach the basic Royce Gracie techniques.  We focus on position, getting into a better position, once the position is covered then we focus on joint manipulation and chokes.  We always teach position first.  If you can’t get out of a hold then you might have to break something.  But chokes are the ultimate neutralizer.  Take for example an attacker is a very big strong guy and has some alcohol and drugs in him and he is not feeling much.  But the one common denominator he has with any person he is attacking is that he needs blood to his head.  So choking is the ultimate neutralizer … it can give you some time to get away from them and run if they pass out for a few minutes from a choke hold.
