Professor Lucas Lepri demonstrates a sequence of attacks from the closed guard. The initial focus is on breaking the opponent's posture using collar grips. If initial collar choke or other attacks are defended, the technique shows shifting the hips, bringing a knee inside, and using knuckles on the opponent's neck to create space. This allows movement of the head towards the opponent's knee and under hooking the near side leg. By pushing the opponent and forcing them to base, a leg is passed over for a triangle choke. Details include securing the arm across, adjusting the triangle, and keeping the knee close to the opponent's ear. If the opponent postures up to defend the triangle choke, an armbar becomes an available option. A shoulder lock is also mentioned as a possibility.
