When his opponent shoots for the single leg takedown and he begins to counter with a loop choke attack as shown in
Part 2, his opponent realizes the danger they are in and gives up the takedown attempt and trys to back out. As this happens, Braulio holds onto them with a front headlock type control and grabs the other lapel with his free hand before pulling guard and finishing with a sliding lapel variation of the loop choke.
