Professor Edson Oliveira demonstrates a technique for escaping from the half guard and maintaining control after he passes. He starts in a position where the opponent is attempting to keep the half guard. To prevent this, Edson establishes a strong position with his knee on the floor, pinning the opponent's leg and covering their under hook. He explains how this prevents the opponent from advancing their position. Edson then shows how to control the opponent's near side leg and use your head position to create space and maintain a dominant position. From here, he demonstrates different options for controlling the opponent or even passing to side control.
