It probably has something to do with the fact that the next local tournament is no gi, but Rodrigo had us working on no gi chokes Monday afternoon. We did the baseball choke, no gi style and he showed us how to transition to the brabo choke if your opponent got the underhook on you and began a proper escape. Last, he showed us a transition to guillotine (with a sort of faux brabo grip).
The no gi baseball choke comes from the crossbody. You want have your northside arm behind the head with the blad of your forearm along the back of the opponent's neck. You want to bring your southside arm up tight, with your hand on your ear, to prevent him from getting the underhook. You can even disguise your bringing up that southside arm as just trying to block his underhook.
Catch your southside hand in your northside hand and apply the choke by dipping your southside shoulder and squeezing your elbows together.
The brabo comes if the guy gets the underhook on you and starts to escape. The trick to getting the brabo is the angle. You want to work yourself back behind the guy, not just back off. For one, you want to keep the connect. For two, by getting behind the guy's shoulder (moving to the south) you can get a longer reach under the guy's arm and neck with your inside brabo arm.
The other trick is to push down on the guy's head to help get your brabo arm through. You should be able to cup the guy's neck easily with the hand of your brabo arm. The locking arm is almost (almost!) just a detail.
The guillotine transition comes if you can't get the good reach with the brabo arm. Shorten up the brabo reach and attack the neck with a guillotine. With the other arm, reach under the guy's arm (between his head and shoulder) and reach under the shoulder and across the lat. It's sort of a brabo-ish guillotine. Drop back into guard--preferably closed guard--to finish.
I've got to say that this is a huge sequence for me. When you throw in the Anaconda choke and the d'arce, you're looking at five different choke attacks from the side control/side control escape or all fours position. I'm here a lot when rolling, so these chokes would be a great addition to my attacking repertoire.
