Dave Camarillo goes in depth on a powerful armlock from top half guard. This is a Dave specialty. Dave aggressively pins the undertook and steps over the head. He then threads his leg under the arm to make a V o n the half guard leg. To finish he fulcrums the arm out of the defense.
This is an attack from the standing position to the shoulder Lock Submission. Essentially you are giving up on being normal and want to attack without pulling guard. It is not so much a flying attack as it is an attack that originates from the heart of the creating chaos theory. Have Fun!
