Arm in Guillotine Choke vs Double Leg Takedown. From South Georgia Submissions #4

Both guys come out fast there is an attempted guard pull but it fails to control the top guy. Neither competitor can find a control position on the ground. Back to the feet, one guy shoots a fast double leg but he leads with his head fails to maintain proper spinal alignment allowing his opponent to lock up the arm in guillotine choke. The guy caught had a chance to defend before the other guy went to full guard after that it was a wrap.
