I was thinking about this thread in a roll earlier today. (apologize in advance for bringing Gi talk into a no-gi forum;) A trick Clark Gracie showed me a little while back that I hadn't taken advantage of enough is gripping both your hands on one side of his lapel and tugging him down, as you pull your legs in as well. Clark works the omoplata or cross choke/arm bar sequence from there, but I found it's a perfect setup for rubber guard in the gi. It doesn't matter where his hands are; you're gonna break his posture. I've found it very, very difficult for the guy to win the posture battle if he lets me get 2 on 1. The 2 on 1 is just so damn powerful. I haven't met a guy that's been able to keep his posture when I tug him in like that, even if his hands are on your hips or pinning your chest. Guy I went against fell in like everyone else had, but this was the first time I had ever applied the principle since learning the basics of rubber guard. He fell right into crackhead and eventually gave me a triangle. There was also a lot of friction preventing him from posturing up, and my understanding as to one of the main reasons rubber guard was created was because Eddie didn't have the added friction to help out. So from a gi perspective, I think rubber guard can work magic, especially with the ability to break the guys posture w/o him expecting it to happen so suddenly as with this method.
