Here we have Braulio Estima black belt, Chiu Kwong Man working the "Golden Arm" from the guard. This is a nice addition to the Golden Arm Half Guard series that I developed here at No-Gi-Grappling.com.
First, Chiu demonstrates a Triangle setup when someone traps your leg during the first Triangle attempt. Then he goes into a sweep and how to take the back. All good stuff here .
