I remember Jacare (the mundial champion) showed the exact same reversed ezekial choke in an old edition of Grappling Mag. When I first saw that technique I was thinking "no way you can finished with one arm trapped under his armpit".
I am going to try that next time I roll with a gi. I don't know how difficult/easy it is to pull off but it would appear to be much easier to lock up than a rear-naked.
why are people pretending that it's suspicious when tank has lost 7 out of his last 8 fights. Not only that but he has a history of getting choked and tapping early.
