Passing Half Guard Tips

When passing with my right leg trapped. Head control and deep underhook with my right arm. Pass the lapel with my right hand to my left. My right arm extends at B's elbow to keep their arm extended, preventing their underhook. My right leg/hips sink down and move towards B's feet. My left leg also extends down, trapping B's leg. I can bring my right leg out towards mount. It's okay if my foot is trapped. My right arm creeps up and to the left to isolate B's arm. My right hand can then grab my left elbow, resutling in B's arm being trapped beneath my chest/or their arm being extended up in the air. *Puts them at risk for americana*. Threatening with the sub can force them to open up their leg so that I can pass to mount.
