I have to get this out of the way before some shitnoob asks about it.
Here's the best anaconda instructional online today. Stephan Kesting put it on his site as promo for his new MMA series with Denis Kang (which I hear is pretty good):
That should answer pretty much every question about it ever.
On the other side of the move, here is the only anaconda-specific escape I've ever found. It comes to us from Strong Machine (may he live forever):
"Incidently this is an extremely easy choke to defend. There is nothing keeping you from reaching your arm trapped inside (we'll say the right arm) down toward your legs as your left knee comes up near your face. Now you are grabbing your own hamstring and you can mulekick your leg straight. The powerful ass muscle contraction overpowers even a much stronger guy's upperbody, stretching your own deltoid inches from your neck. I've never had this escape work anything less than perfectly even on completely locked in anacondas."I also wrote this for a friend's blog where he was talking about the anaconda and brabo chokes:
After the last UFC and Randy's win with an anaconda, I've heard from quite a few people that they are learning this choke in class. This also happened when Minotauro won two Pride matches with it.
For some reason the anaconda and the brabo are prone to these cycles of popularity. Someone will win a high level event with one, then it will sweep general grappling population, then fade away.
I think this is how the brabo got so many names. It was called the "brabo" when Leozinho was winning with it. Then Shaolin got a string of wins with it, earning it his name. Now D'Arce, a Renzo Gracie black belt, has become the latest namesake for this choke.
I hope you enjoyed this History Minute.
