@Aiseop (Poesia? "Poetry" in Portuguese? Nice.):
This explains why with all the omoplata setups that we practice in the gi, this choke has never come up. I think if I sat up from jiu claw without flattening the opponent first my teacher would assume I haven't been paying attention in class.
Anyways, excellent discussion.
Anyway, this is really "extra" since in a flowchart for most of us it would fall after omoplata, sweep, log roll, wrist lock, etc. In MMA and nogi, the Imanari is a much more "first option" than gi.
Anyways, excellent discussion.
