Professor Edson Oliveira demonstrates De La Riva guard attacks, aiming for a back take or sweep when the opponent defends. He uses deep lapel control to counter the opponent's knee-on-floor defense. If the opponent squares up, Edson uses a hook to lift their leg, setting up the back take. Alternatively, he can transition to a scissor sweep. The technique emphasizes tight control and adapting to the opponent's reactions to secure a dominant position.
