Overhead Sweep Armbar

Executing an armbar from the De La Riva Guard involves several steps:

1. Start in the De La Riva Guard, maintaining control of the opponent's hand and breaking their balance.
2. Attempt a scissor sweep. If the opponent bases out with both hands to prevent the sweep, prepare to transition to the armbar.
3. Switch your De La Riva hook to the outside of the opponent's leg.
4. Shift your hips and swing your leg over the opponent's head to secure the armbar position.
5. Ensure your legs are tight around the opponent's body and control their arm firmly.
6. For better control, you can use a Kimura grip on the arm or a regular armbar grip.
7. Practice the transition with a partner who places their hands on the mat, allowing you to break their balance and lift them as you would in a live situation.
8. Remember to switch your hip and choose the correct leg to swing over based on the side you're attacking.

This technique is a variation of the armbar from the closed guard, adapted to the De La Riva Guard, and is effective when the opponent has a strong base and resists the initial sweep attempt.
