Closed Guard | Stack Pass | Duck Under

Executing the Duck Under Pass when facing resistance during a stack pass:

1. Begin the stack pass by pushing the opponent's knee under and sliding your knee to the side you intend to pass.
2. Look to the opposite side and open your knee as you hug the opponent's head to initiate a long stack.
3. Ensure your middle finger grips the opponent's armpit to apply shoulder pressure.
4. As you long stack, transition your grip from the opponent's collar to their knee.
5. Perform a compass-like motion with your leg and slide your hips to maintain shoulder pressure.
6. If the opponent pushes and attempts to recompose the guard with their top leg, place your hands on the mat and hide your head in anticipation of their leg coming over.
7. Duck under the incoming leg, underhook it, and bring the leg over your shoulder while applying pressure towards the opponent, not downwards.
8. Slide your knee over the opponent's thigh, releasing the grip on their leg as it's no longer needed.
9. Move your hands under the opponent's hips, avoiding the common mistake of placing weight on your hands.
10. Windshield wiper your leg to stack the opponent, leaning forward to apply pressure and control their hips.
11. Drag the opponent's leg across as you transition to a leg drag position, maintaining shoulder pressure and head position to stabilize the pass.
