2 Part Lesson — Marcelo takes a Single after his opponent invades his Butterfly Guard: [I] If your opponent presses forward and steps in between your Seated Guard before you can place your shin in front of his lead; grab his leg, post behind, crunch forward, and take any pressure off of your head by grabbing his wrist. Use his own arm to ward off his other hand from pressing you back down as you lift his leg and finish the Single by Running-The-Pipe. [II] If your opponent is insistent upon pushing you back down with his free hand, post behind and swivel around his lead foot. Keeping hold tight, release his wrist as you come up and rehold his ankle/calf to finish the Single Leg Takedown. If he escapes before you can tighten the Single as you rise, just remember to bypass this scenario altogether by placing your shin in front of his foot as he steps inside.
