Shoulder Crunch Sumi Gaeshi - Butterfly

Executing the Shoulder Crunch Sumi Gaeshi from Butterfly Guard:

1. Start in a kneeling butterfly guard position.
2. If your opponent attempts to flatten you out with a head and arm control, drive your hand on the same side as their underhook underneath their neck, creating a frame with your forearm against their throat.
3. Connect your other hand wrist-to-wrist with the forearm frame, establishing a shoulder crunch grip. Squeeze their shoulder into your chest.
4. Coil your core tightly towards the side where your elbow is in front of their chest, lifting your other elbow towards the ceiling.
5. Keep your ear back towards their wrist to prevent them from posting.
6. Extend your legs and sit up to your butt, maintaining the tight coil.
7. Lift your left elbow to keep their elbow away from their hip, making it difficult for them to post.
8. Step on their knee and stretch them out completely.
9. Turn them over using your elbow in their sternum, transitioning to mount.
10. Post your hands, collect their head, and prepare to attack from the mount.
