One Hand Rolling Choke

Executing a rolling choke from the bottom half guard begins with establishing a knee shield and attempting to secure an underhook. When the opponent blocks the underhook and applies pressure, the following sequence is initiated:

1. Post on the free arm's elbow and insert the hand deep into the opponent's collar, maintaining it as a frame.
2. Use the knee shield and forearm grip to manage distance and opponent's weight.
3. When the opponent pressures forward, kick the knee shield leg out straight.
4. Pull the opponent's head towards the waist and loop the arm over their head, setting the choke in place.
5. Grab the outside of the opponent's pant leg with the hand corresponding to the elbow you're posted on.
6. Push off with the foot of the straightened leg to initiate a roll.
7. Complete the roll to land in the top half guard position, where the choke can be finished.

This technique capitalizes on the opponent's defense against the underhook to set up a choke, using the transition from bottom to top position to secure the submission.
