The Rubix Cube coming out of 10th Planet Hollywood is a pretty cool technique. I actually remember seeing Sean Bollinger using this tech in class.
At the point that you trap your opponent's arm with your ankle you have to make sure that you get your foot deep into the crook of their elbow. I'm talking about so far that your shin is in the crook of their elbow.
If you just stick your foot or ankle into their elbow you risk putting yourself into a foot lock.
The Puppet Master Series works nicely off of this position. Go to the Rubber Guard page to check it out!
