Professor Lucas Lepri shows how to apply the triangle choke while inverting from z-guard against an opponent's knee cut attempt. As the opponent knee cuts with one hand weaved and the other gripping Lucas' lapel, Lucas breaks the opponent's lapel grip and inverts. This time as Lucas spins he grips the opponent's other arm, holding it between his legs until he is able to lock the triangle. Lucas then keeps his opponent's posture broken as he adjusts his legs and tightens the triangle, ultimately hugging his own knee to finish the submission.
