I am not talking about where you stay in position and armbar the guy when he rolls. This is a move that popped in my head the other day, and I am wondering if anyone has any details that can make it more effective. You let the guy roll and take top from the omaplata, and sit on the arm facing his legs for a twister side control (reverse 100 kilos) position. If he turns into you, you take the leg not trapping his arm, slide across for mount with your top arm cupping his tricep, and go to the arm bar. Because you were sitting on his arm it is VERY hard for him to do the RNC-style defense. If he turns away (not sure why they would, though) you pull up on his trapped arm with your top arm, throw your trapping leg over, put your other leg against his ribs and get the near arm. If you're like me, you are going to have NO idea what I'm talking about by reading the description, but hopefully someone will be able to, so I don't have to post a video.
