Arm Drag | Crotch Lock | Rear Naked Choke

Executing an arm drag to crotch lock and transitioning to a rear naked choke from the half guard shell:

1. Maintain close proximity to the opponent, keeping the elbow close to the knee to prevent them from finding a way inside your frames.
2. When the opponent attempts to go under your leg, possibly aiming for an over-under pass, shove their head to the side while moving your back away to avoid a crossface.
3. With your free arm, reach underneath and secure a grip on the opponent's tricep.
4. Use your leg as a pendulum to sit up, pulling on their arm, and immediately grab the opponent's foot to prevent them from retracting their arm.
5. Reach behind the opponent's arm with your free arm to assist in standing up on your knee.
6. Once up, decide whether to secure a seatbelt grip or opt for a crotch lock to potentially take the opponent's back.
7. If choosing the crotch lock, you can pull the opponent's hip towards you to off-balance them.
8. If the opponent fights your hands, control their wrist and forearm, staple their hips to the mat, and swing your leg over.
9. Secure a 'police lock' on the opponent's arm, creating an opening to slide in for a rear naked choke, whether in gi or no-gi.
