BJJ Double Under Pass Guide: Master Hip Control & Guard Passing

**Establish Double Under Grips:** Begin by getting deep under both of your opponent's legs, securing strong grips on their pants near their knees or on their belt, ensuring your elbows are tight to your body.
**Lift and Stack:** Drive your hips forward, using your legs to lift your opponent's hips off the mat, effectively stacking them onto their shoulders and upper back.
**Pin Hips and Knees:** With your opponent stacked, use your chest and shoulder pressure to pin their hips and knees to the mat, preventing them from creating space or moving their legs.
**Walk to Side Control:** Maintain constant pressure as you slowly walk your feet around in a semicircle, pivoting towards one side of your opponent's body.
**Secure the Position:** Once you've cleared their legs, settle into a dominant side control, chest-to-chest, securing head and arm control or cross-face and Underhook.

**Hip Control is ParaMount:** The success of this pass hinges on your ability to control and elevate your opponent's hips; without it, they will easily recover their guard.
**Constant Pressure:** Never relieve pressure once you've committed to the pass. Any momentary lapse allows your opponent to re-establish frames or leg hooks.
**Head Position:** Keep your head up and chest out, maintaining a strong posture to avoid being swept or entangled.
**Small Adjustments:** Be patient and make small, incremental movements to clear the legs rather than trying to power through in one big push.

**Double Under to Leg Drag:** After lifting and stacking, instead of walking around, you can transition directly into a leg drag by isolating one leg and pinning it.
**Double Under to Stack Pass (Direct):** A more direct version where you focus solely on stacking and holding the opponent in a high stack, often leading to a quick knee-on-belly or side control.
**Double Under to Smash Pass:** Utilizing the double under grips to drive forward and flatten the opponent, often combining with a cross-face to smash their guard.

The Double Under Pass is highly effective when your opponent has a strong open guard (like Spider Guard, lasso guard, or DLR) and is actively trying to keep you at a distance with their feet. It's also excellent when you can get under both of their legs and lift their hips, negating their leg dexterity.

**Leg Entanglements:** Opponents will often try to transition into leg locks (heel hooks, toe holds) or set up sweeps from deep half guard if you commit too deeply without proper control.
**Triangle/Omoplata Setups:** If your head is too low or your arm extends too far, the opponent can use their free leg to set up a Triangle Choke or omoplata.
**Creating Space and Framing:** A common defense involves using frames with arms and powerful hip escapes to create distance and recover guard before you can fully stack them.
