In this technique, we explore how to execute a one-arm-in choke when facing a double underhook pass that leads to a stack. Here’s how you can effectively apply this choke:

  1. Initial Position: As your opponent attempts a double underhook pass, begin in a similar manner to setting up the Americana, positioning your arm over theirs. However, find that it's too tight to execute the Americana properly.

  2. Creating Space: As your opponent begins to stack you up, use the foot that you have on the ground to scoot your hip sideways. This movement is crucial as it creates the necessary space for your arm to maneuver.

  3. Securing the Choke: With the space created, slip the same arm that was pushing (the one initially intended for the Americana) underneath your opponent's near arm and head. This positioning is key to setting up the choke.

  4. Final Adjustments: With your arm in place under your opponent’s arm and head, use your free hand to guide their stacked arm across their body. This helps isolate the neck and secures it in position for the choke.

  5. Locking in the Choke: Once you've adjusted their arm out of the way and secured a grip on their head, pull their head down towards you as you tighten your grip, locking in the choke. The setup should feel snug and controlled, with your opponent's stacked position actually aiding in tightening the choke.

  6. Execution: Ensure that as you perform this move, you maintain tight control and adjust your body positioning to maximize the choke’s effectiveness. The key is to keep your hips mobile to adjust as needed and use your opponent's stacking motion against them to finalize the choke.

This one-arm-in choke serves as a powerful counter to a double underhook pass, turning a defensive scenario into an offensive opportunity by using precise positioning and effective hip movement.
