Try this fellas and tell me what you think. In gaurd, go forward and get kesi-gatame grips. Hold this like you have osaekomi. Tight. Pull forward while climbing thru. He will try to sneak out the side and take back every time. If you have him tight, let him loosen and you inch up with your knees, pulling in your kesagatame. You will end up where he is at your side and you must keep the head and arm tight. From there you will pull thru physically and have it or he may have one leg and you are fine to go. You must keep his head beside yours. With his head and arm you are easily dominant.
