The audio is about 20 seconds ahead of the video so I had to turn it off.
That was a pretty good fight. I like how active Gillespie is on the ground and that he isn't afraid to strike to set up a take down. There seemed to be times where he didn't seem to know how to transition to the next position. For a good minute he had Pinchel's back and just blanketed him. It is a good strategy to tire some one out but doesn't do anything for you in the judges eyes. He finally got the particular submission he had been trying to get the win so good for him.
I am not sure why fighters who get in that position just stay and try to use the elbow to push the head away, your basically pitting one relatively weak muscle group against both arms and the back. A lot of times the window to raise up on your hip and slide away is there but they get to focused on the choke instead of positioning them selves out of it.
