Collar Choke from Back Control with Variations (Intermediate)

Professor Edson Oliveira demonstrates a collar choke from back control, emphasizing grip details and variations. He starts with back control and an overhook, then stresses the importance of opening the opponent's collar and securing a deep grip. He transitions to a collar grip with the other hand and demonstrates the choke by extending his arms, placing his forearm on the mat, and pulling the collar towards the opponent's feet. If the opponent defends by controlling his tricep, he shows a variation involving scissoring his legs and raising a knee to control the opponent’s shoulder. He also shows how to bring the opponent closer to him to make the choke more effective.
