2 Part Lesson -- Marcelo finishes a forced single out the back door: If your opponent is insistent on picking up your ankles to place your back flat on the mat from a Seated/Butterfly-Guard Position, try posting behind yourself to circle your feet free from any grips. However, if your opponent continues to drive forward as you sit back up to play, meet his or her advance with a Single Leg Take-Up (followed by a finish to complete the sweep/takedown). You may also use this opportunity to pummel your foot in front of your opponent's lead leg to play Shin-on-Shin and enter into Single-Leg-X. [06:08] If your opponent commits his or her weight forward so much so that one ends up draped over top of you as you sit up onto the Single, duck your head under the opponent's leg and come up with the leg out-the-back-door.
