### Step-by-Step Instructions:
#### Initial Setup: Standing
1. **Distance Monitoring:**
- While standing, maintain a safe distance to control the engagement. Look for an opportunity when your opponent is either stepping forward or retrieving their leg, making this an opportune time to initiate the roll.
2. **Dive Under:**
- As your opponent steps closer, lower your level and ***dive with your shoulder aiming towards their leading leg***. This allows for a seamless underhook on their knee as you roll beneath them.
#### Execute the Roll
3. **Tuck and Roll:**
- ***Tuck your head tightly*** against their shin while grabbing onto their ankle with both hands.
- Instantly execute a ***forward shoulder roll***, passing your body under your opponent's hips.
4. **Leg Capture:**
- As you roll through, swiftly ***trap their leg between your thighs***, bringing your knees tightly around it.
5. **Control the Opponent:**
- Use your grip on your opponent's ankle and your thighs to manipulate their leg's position, keeping it controlled as you transition to finish.
#### Submission Finish
6. **Lock In:**
- As you complete your roll, position yourself in an advantageous leg entanglement like the Ashi Garami. Use your free hand to ***secure their foot*** further.
7. **Hips In, Arch Back:**
- Drive your hips upward while ***arching your back***, applying pressure to the opponent’s knee joint, effectively finishing the submission.
8. **Knee Pressure:**
- Ensure that your thighs squeeze tightly around their leg. Inflate your chest and ***create relentless pressure*** using your upper torso and hips to enhance the lock effectiveness.

### Key Points to Consider:
- Timing is crucial; initiate the dive and roll when your opponent is moving forward to catch them off-balance.
- Maintain control of their leg throughout the technique to prevent their escape.
- Ensure your body positioning is tight around their limb to avoid giving them any slack which could lead to a counter.
- Always practice with a partner in a controlled environment to ensure safety; knee locks can be hazardous if applied improperly or if a partner is not prepared.
With patience and practice, the Rolling Leg Lock can be an unexpected weapon in your BJJ arsenal.
