2 Part Lesson — Marcelo purposefully mixes up two different arm attacks to confuse his opponent: [I] Instead of spinning around the opponent with an Underhook for the Farside Armbar, step over into Mount for the Spiral Armbar; let his arm fall off of your Underhook onto your lap to secure his elbow for the lock. [II] If your opponent rolls into you after taking the Mount (Reverse Technical Mount, Ukegatame) Position, allow his arm to slip down into the Omoplata. Take the top position and find a grip on his far-side to finish the shoulder submission.
