Americana from Closed Guard

I found myself doing this a few times and worked well for me so far. I didn't know the choke variation part though. Now I gotta try the choke part. I find it easier to implement than a arm-bar from guard, since there is no need to strech out the arm, and swing to the other side and break posture. Fewer steps and less risk, since no need to open the guard completely I think.
