Side Control to Triangle or Armbar when Opponent Underhooks (Advanced)

Professor Lucas Lepri demonstrates an approach to finishing with a triangle choke or armbar from a controlled position where the opponent's arm is isolated. The goal is to develop the sensibility to choose the right attack based on the opponent's body type and defense. Lucas shows a technique to set up the submission by using a push/pull action on the opponent's arm to create an opening and securing a grip on his own shin. This puts Lucas in a position to either fall back and lock the triangle or armbar. For larger opponents, when the triangle is challenging, Lucas avoids falling backward and instead maintains a knee-up position, driving his knee close to the opponent's ear to finish the choke from a stacked position, or transitions to the armbar by falling back and immediately securing the limb. This segment emphasizes the critical need to practice and feel the right transition based on the opponent's size and defense.
