### Introduction to the 50/50 Heel Hook The 50/50 Heel Hook is an intricate Brazilian Jiu-Jitsu submission targeting an opponent's ankle. Emphasizing leverage over strength, it is performed from a position known as the 50/50 Guard, widely used in competition for its effective control and submission opportunities. ### Japanese Name *Currently, there is no specific Japanese name widely accepted for the 50/50 Heel Hook.* ### Position - **50/50 Guard** This unique guard position involves both practitioners having mirrored leg entwinements, allowing for both control and sweeping possibilities. ### Step-by-Step Execution 1. **Establish the 50/50 Guard** - Begin by sitting opposite your opponent with your right leg threading over their left thigh, while your left leg hooks beneath their right. Your bodies are mirrored, and each is seated. 2. **Control and Secure** - Use your left arm to hold behind their calf, ensuring their leg remains tight against your body. - With your legs interlocked and knees pinch inward, prevent them from retreating or adjusting easily. 3. **Isolate the Heel** - While controlling their calf with your left arm, use your right hand to cup the back of their heel. This action positions the foot, so the toes point within the gap your left arm creates when gripping. 4. **Adjust Your Body Position** - Slightly rotate your body towards their trapped leg while sliding your hips out to the side. This not only tightens your hold but also adjusts the torque on the captured leg. 5. **Secure the Submissions Grip** - Transition your right hand grip to the top side of their foot while your left hand reinforces the grip by wrapping and clasping over the back of your right hand. 6. **Engage the Submission** - Begin to slowly and controlledly rotate your upper body against the locked heel, twisting their foot outward. - Maintain pressure by ensuring their knee is immobilized between your chest and secure them within the guard. ### Important Considerations - **Safety First**: Heel hooks place significant stress on the knee joint. Apply slow pressure and ensure training partners are aware of the potential risk. - **Control is Crucial**: Prioritize establishing control over their leg before attempting the submission. - **Flow Management**: The 50/50 Guard position permits transitions into alternative leg locks or sweeps, allowing for diverse strategic utilization. ### Conclusion With careful execution and respect for your training partner's safety, the 50/50 Heel Hook offers a powerful submission opportunity in both competitive and training environments. Mastery of this technique requires patience, sensitivity to pressure, and relentless practice.
