3 Part Lesson — Marcelo reverses his opponent's Half Guard to Pass: [I] If the Knee Slide or Knee Across Pass aren't available because you can't find an Underhook before your opponent begins to sit up on the Single, switch to the opposite side for the Backstep Pass. Find the Underhook as soon as you land; if your foot is trapt, use your outside leg to kick yourself free into Side Control. [II] If you have no Underhook, capture the opponent's heel while he holds a Figure-Four around your leg. After you pass, circle toward the North/South Position to stabilize. [III] If he's holding your leg in Reverse Half, slip a Reverse Underhook inside his far armpit and finish the pass, not releasing the toehold until you set the N/S Position.
