On people who suck at tourtling this should be a good move. I'll definetely try it out. Doubt it will work on any advance trutler thou. The again when people are shooting the are shooting.
I've actually never thought about it like that, but yeah. I think Mino called it the Anaconda?
The keys for me are the switching of the legs to get the guy to roll (if you dont post and shoot the opposite leg through fast enough, the guy wont roll sometimes and end up in kami shiho), and the walk/spin towards uke after the choke is applied (ie. last pic. It's this walking motion that tightens the choke, since there is no body weight involved like a kata gatame). Other then that it's pretty straight forward I think.
hard angle to finish the choke, especially when there is a gi involved.. but, so long as your are tight and really have it cranked in, it can finish people off.
"It is not really a reverse kata-gatame, although it looks like it"
CBT, I've done the choke on people in sparring. The choke is a head-and-arm choke, so it is a type of Kata Gatame. The position of the attacker is 180 degrees from the traditional position, so that would make it a reverse Kata Gatame. You do go off on an angle slightly when the rolling choke is done, but you also go off on an angle with traditional Kata Gatame.
I was very impressed with Mino's use of this tchnique. I believe he's actually finished 2 opponents with this in Pride fights. Thank you for posting the step by step.
