I gave this a whirl yesterday & it worked well against a newbie & almost caught some guy who I train with regularly. I only call it Bas' because I saw it on one of his DVD instructionals. The sit down mount is exactly what it sounds. One leg at a time you pull your foot forward & get your thighs beneath their arms. From here, you have all your weight sat on their chest with your feet up past their head. Here you can switch to an armbar pretty easy. Just wondered if you guys use this or the sit down mount with other moves you could suggest. I thought it would be easy to slide your leg behind their head & intentionally roll back to guard position to catch a triangle. I'll give this a shot next lesson.
