Haha, forget defending it, I wanna use it!  The second video;  that was a very interesting "guard" he had at the 49 second mark.  Technically, he was passed.  But he was able to use those two hooks in a way similar to lockdown.   Looking forward to reading the comments of expert eyes.   This is really intriguing to me.  It's making the best of a bad position.  The baseball choke and that strange "guard."     Creative stuff.
