2 Part Lesson -- Marcelo breaks his opponent's Underhook from Half Guard: If your opponent secures an Underhook, possibly with a grip on your jacket, explosively turn your shoulders into the arm; make grips on the sleeve above the opponent's elbow and begin pressing the arm away. When sufficiently removed, pummel your own Underhook inside the opponent's armpit and finish the pass with Underhook & Crossface or Underhook & Overhook. [02:10] If your opponent doesn't budge when you whip into his or her Underhook, immediately apply a frame against the neck. Wedge your elbow inside until you can clear the arm and pummel an Underhook of your own for the Half Guard Pass.
