2 Part Technique - Once you've flattened your opponent in his Half Guard with a tight Underhook & Head Control, the pass should be imminent and the points are yours for the taking. Since you realize he has no effective counter, take the time to think about your next attack after the pass, preparing to act based on his reaction. Doing such will keep you one step ahead of your opponent, and oftentimes make short work of an otherwise difficult match-up. If his nearside arm is bothersome, pin it to the mat for a clear path to the North South Choke. If his other arm frames you away while looking for the North South, take Mount and lift his head and arm into a Triangle.
