Rigan Machado Counter to the 50/50 Guard

I shot a video for this solely because I find it impossible to continue to refer to this technique as 'that fifty fifty counter from Rigan's book, I think it's move 16, anyways, that one' when trying to tell people about it. You can actually see it as move #16 and move #20 in his book Encyclopedia of Leglocks. The technique he shows isn't PRECISELY against the 50/50, because no one used it when he made the book. But it works exactly the same with your leg threaded through and triangled as it does in his demonstration. However, here is a brief video showing how it works. As usual feedback is welcome. This is NOT a detailed how-to guide for the technique. Remember this is just a reference video to give you the basic idea.

As usual commentary is welcome.
