I don't have a particularly deep background in all of these things, but I'd like to think that I've been exposed to a tremendous number of things that just don't plain work as advertised outside of the venue in which they are demonstrated - if even there. Chokes have always seemed the great equalizer, and was the first "move" that really started sucking me in to the greater expanse.
I appreciate you taking the time to video and present this, Cecil!
LOL @ the second vid posted, as relates to what happens when people try some goofball stuff to "beat the choke." Like the last guy who tried to break my pinkie during friendly sparring because I got a rear naked...
