Rafael Formiga Barbosa is considered to have one of the best butterfly guards in the world of modern BJJ. He is known for his butterfly guard sweep to armbar and has hit it multiple times against some of the best grapplers in the world. Formiga is a multi-time IBJJF World’s Masters Champion, and has also medalled multiple times in the IBJJF Worlds Championships.
In this BJJ butterfly guard sweep video, Formiga uses his opponent’s driving energy for attacking the head and essentially hits a duck under the sweep on the other side. This move is oddly similar to the wrestling concepts of hitting a duck under to back control.
This butterfly guard sweep allows you to get a quick straight arm bar submission or come to the back and get 4 points for the back take.
