The GIF above is actually from the fight with Ed Herman, and is the first of two times he pulled off this technique in that fight.  He hit it again last night against Jason MacDonald, and I marked out pretty hard for it.

I wanted to point it out because it shows just how advanced his BJJ game is.  He starts by allowing his opponent to start passing his guard.  While Herman tries to push Maia's knee to the mat, Demian grabs wrist control and extends his arm forward.  When Herman posts up on his left side, Maia brings his right leg back towards his head and then up around Herman's controlled arm into a triangle.

To those who listened to Luke's MMA Nation show last week, THIS is an example of world-class jiu jitsu.
