|Don't ask... I have no clue, but it is technically an omoplata!|
The omoplata is one of my favorite attacks and can be quite effective for cats with long lanky legs such as I! Here is Schembri's highlight real on omoplata attacks:
And finally here is a clip of Demian Maia's take on the omoplata. I can personally attest to the detail oriented approach Maia takes, as I trained with him once while visiting home a few years ago, and the guy taught very simple stuff, but the details were money!!
Lastly a little reminder of the David Meyer and John Will bonanza that is coming to a dojo near you (one can only hope to glean some of the details of the omoplata from John Will!!):
