### Neck Crank Technique
#### Overview
The neck crank is a submission technique in Brazilian Jiu-Jitsu (BJJ) and grappling martial arts that forces the opponent to have their neck twisted or bent in an unnatural position, causing discomfort or pain.
**Note**: Caution should be applied when executing this submission, due to the potential for serious spinal injury.

### Step-by-Step Instructions
#### From Side Control (Top)
1. **Establish Side Control**
- Secure side control by pinning your opponent with your chest to chest position.
- Control their near-side arm using your crossface.
2. **Set up the Neck Crank**
- Transition to a Kesa Gatame (scarf hold) position while maintaining secure control over your opponent's neck.
- Use your left arm to cup the opponent's head, placing it inside the crux of your elbow.
3. **Adjust Position**
- Shift your weight towards your legs while keeping your opponent's head and neck in place with your arm.
- Place your right hand under their far-side arm, reaching across the chest. Alternatively, you can use a gable grip to secure both arms.
4. **Execute the Neck Crank**
- Once the position is secured, apply pressure by rotating your hips downward towards the opponent's head.
- This will create tension in the neck, encouraging your opponent to tap out.
5. **Maintain Control**
- Ensure your position is stable by using your chest or shoulder weight for maximum control.
- Be mindful of the pressure applied to prioritize safety.
#### From the North South
1. **Establish Position**
- Begin in North-South position, ensuring that your opponent's head is aligned between your legs.
- Use your hands to control their arms to prevent any form of escape.
2. **Trap the Head**
- Shift your body slightly to one side, allowing your arm to secure their head.
- Cup the back of their head with your opposite arm and pull it up.
3. **Secure Opponent's Head**
- Drive your body upward to tighten grip around the opponent’s neck.
- Transition by adjusting your posture while using your own body weight to apply consistent pressure.
4. **Apply Submission**
- Elevate your hips in a bridge-like manner, using your upper body to apply the neck crank.
- Carefully increase the pressure as needed until your opponent taps.
### Key Tips
- **Breathing and Balance**: Always control your own breathing and maintain a strong base to prevent counters.
- **Minimize Injury Risks**: Always practice with control and ideally under supervision, especially if you're new to neck cranks.
