Butterfly Hook Sweep

Executing a Butterfly Sweep from the underhook position is effective for all skill levels. Maintain good posture with a strong underhook and head up, ensuring you're connected to your opponent without any looseness.

1. Hook your foot onto your opponent's foot, turning your toes down and wrapping the instep of your foot underneath their ankle.
2. Scoot back and straighten your leg to lock their knee in place, preventing them from moving it forward.
3. Replace the control of their leg with your other foot, securing the inside of their knee, and remove the initial hooking foot.
4. Keep your head close to your opponent and place one hand on the mat for support.
5. Control your opponent's sleeve and stuff it into their body, avoiding falling to your elbow as it can hinder the sweep's momentum.
6. Drop your shoulder to the mat and use your hooked foot to pull your knee to your chest, loading your opponent onto your legs.
7. Use your free leg on the floor to push off and complete the sweep, tilting your opponent over.
8. Once on top, slide your shin over their arm to secure a top crucifix position, providing control and setting up for submissions like Americanas or armbars.

This simple sweep is difficult to counter when executed correctly from the underhook position.
