Figured I'd share another video with all of you. This one is a 3 move combination from the guard position.
You go for an armbar from the guard. Then your opponent either pulls his arm out or you just switch to the oma plata on your own. A common defense is for you opponent to posture up when you attempt the oma plata and a great option is to do an explosive back roll as they posture up. You are basically using the momentum of your opponent posturing up and the follow through of your back roll to execute the sweep. In essence you're taking your opponent where he wants to go.
Thanks for watching,
