2 Part Technique - You cannot believe you will pass a tough opponent's guard in 1 technique. A better solution is to work step by step and pass from the Half Guard instead. Use the Under Hook and Head Control in nogi when using the Over Under Pass vs Half Guard. Often, the opponent will win the under hook battle. Re-pummel using your opposite arm to force his under hook down, and swim in for the control. If the opponent cannot secure an under hook, he might attempt to transition into a Deep Half Guard instead. During his movement, he will expose his neck for the North South Choke.
