#### From Closed Guard:
1. **Establish a Secure Guard:**

2. **Use Off-Balancing:**
- Pull your opponent forward to control their posture using your legs, preventing them from sitting back.
3. **First Hand Grip:**
- Use your left hand to reach deep inside your opponent's right collar (their left and your right side).
- Make sure your thumb is inside the collar, and your four fingers are outside grabbing tightly.
4. **Second Hand Grip:**
- While maintaining control, slide your right hand underneath the first hand, and grab the opponent's left collar with a mirrored grip (thumb inside, fingers outside).
5. **Break Posture:**
- Keep your opponent's posture broken by pulling them further towards you with your legs.
6. **Execute the Choke:**
- *Straighten* your arms across, pulling with your wrists downwards to tighten the lapels against your opponent’s carotid arteries.
- Simultaneously, *expand* your chest and pull them into you.
7. **Adjust:**
- If necessary, rock side-to-side or adjust the grips tighter to increase pressure if the choke is not being applied effectively.
8. **Observe:**
- Watch for any sign of the tap; release immediately upon feeling the tap.
#### From Mount Position:
1. **Stay Balanced:**
- Keep a low mount with knees pinched around your opponent to maintain control.
2. **Establish First Grip:**
- Use your left hand to reach into their left collar (across the body) in a thumb-in grip, establishing an anchor point.
3. **Second Hand:**
- Slide your right hand across to mirror grip their right collar with a thumb-in grip.
4. **Compress:**
- Drop your elbows downwards, crossing your arms across their neck while lowering your body weight.
5. **Tighten & Finish:**
- Squeeze and bring your elbows together while expanding your chest as you slowly increase pressure on the choke.
- Ensure to monitor your opponent for a tap or verbal signal.
