2 Part Lesson — Marcelo slices through a slippery guard: [I] Thrust your knee and hip across the opponent's thigh and land next to him or her; if you pummel an Underhook, stay in Side Control. If you land without an Underhook, stabilize the North/South Position. You may encounter an Inverted Guard Recovery, but stay low and dig through until you can keep the top position. [II] If your opponent places you in Reverse (or Inverted) De-la-Riva Guard, circle away from the opponent's head. Pivot around until his or her hook loosens enough to cut through for the Knee-Slide Pass.
