Tonight I was rolling with a blue belt; while in her guard I would rotate my hands to break her sleeve grips before attempting to pass. Unfortunately, doing this caused her fingers to get caught in my gi, and we had to stop the roll a few times because of it. Does anyone have any advice to spare on how to safely break grips? I was thinking perhaps I should pull my arm back with a little hand rotation rather than just rotating constantly, but I'm not sure. Many thanks.
