2 Part Lesson — Marcelo insists on solidifying the pass if presented the back: [I] If your opponent offers up their backside to avoid getting established under Side-Control or North/South, make grips on the far side by the shoulder and hip and yank him or her back flat to secure the 3 points for the pass. Take your weight off the Turtle before pulling the opponent onto his or her back and then placing your chest back on top. Search for an Underhook or even a Reverse-Underhook to establish the Side Mount or North/South, respectively. [II] If your opponent is good, and turns back into you quickly to counter with a Single Leg, quickly hop up to Knee-On-Belly. Push the opponent back down flat from the higher vantage point until you see an opportunity to pummel for an Underhook and establish the Side Control.
