Trying to clear up the difference between all these. So my understanding is that a D'arce choke and an Anaconda choke are the same thing EXCEPT in a D'arce the choking arm threads under your opponents first before going across the neck, and the Anaconda is the opposite, neck first then arm. A barbo choke is just a different name for a D'arce? And a Ninja choke is like a no arm D'arce? Whats the difference?
