The Omoplata is a shoulder lock submission technique predominantly applied from guard positions. It is highly effective in both Gi and No-Gi grappling and demands proper hip movement and shoulder control.
### Detailed Steps:
#### From Closed Guard Position:
1. **Set Up the Control**:
- Begin in a standard closed guard position, with your opponent kneeling or in posture.
- Break your opponent's posture by pulling their collar or head downwards.
2. **Establish Wrist Control**:
- Secure a grip on one of your opponent's wrists, keeping it close to your body.
- Utilize your free hand to reach under and secure their tricep, creating tension and control over their arm.
3. **Creating the Angle**:
- Using the grip on your opponent's arm and tricep, shift your hip to the side opposite of the controlled arm.
- **Optional**: Use a foot on their hip for proper leverage if needed.
4. **Leg Over the Shoulder**:
- With your hips angled, swing your leg on the arm's side over your opponent's shoulder.
- Simultaneously, bring your opposite leg under as if you are positioning for a triangle.
- Ensure that your opponent's arm is trapped tightly across your hip.
5. **Complete the Rotation**:
- Release your opponent's wrist control and with the same hand, secure their back or belt for anchoring.
- With the other leg swinging over, rotate your body towards your opponent in a 90-degree angle.
- Keep your knees pinched, ensuring your opponent cannot extract their arm.
6. **Locking in the Submission**:
- Sit up and move your body forward towards your opponent's head.
- Cross your legs, engaging your opponent's shoulder tightly within your hip structure.
7. **Finish and Control**:
- Apply pressure by driving your top hip downwards.
- Pull infusing upward shoulder pressure by using your hand that's controlling their waist.
- Maintain a forward body tilt, increasing the leverage against their shoulder to achieve submission.
### Key Points to Remember:
- The success of the Omoplata heavily relies on controlling the opponent's posture and wrist.
- Ensure adequate hip movement to create the correct angle.
- Pinch the knees firmly to limit the opponent's ability to escape.
- Keep calm and maintain constant shoulder pressure until submission is achieved.
