Anyone notice Bu Kyung Jung using an odd arm bar starting wit h an overhook from gaurd. IT seems to be the thing he's giving game opponents trouble with [aoki,ishida]. Any thoughts as to why this arm bar isnt used much? Im gonna try it as soon as my next training session. I recall thinking about the possibility of it [over hook to arm bar] but then i never really tried it much. It seems kind of like a common sense move but I've rarely seen it.
