Butterfly Guard Recovery by Rolling Over the Shoulder

Cobrinha shows how to recover your guard when you get stack by your opponent. When your opponent tries to stack you, so before he does it you will choose one side and roll over your shoulder, will grab around your opponent waist and put the hook in, sit on the side and put your opponent back to your butterfly guard. The side you chose to roll over the shoulder is the same side you will grab around the waist.
