Controlling the Underhook

Addressing the issue of the underhook during a knee slice pass is crucial. To counteract an opponent's underhook:

1. As the opponent secures the underhook, immediately step back to prevent them from using it effectively. Use your hand to push their shoulder down to keep them flat on their back.
2. Locate the opponent's elbow with your arm and clamp it down with your ribs to neutralize their ability to use the underhook.
3. Reach back along the opponent's leg and secure a pistol grip on their pants, with your thumb inside the material, locking your arm over their elbow.
4. Drive your shoulder into the opponent's sternum to apply pressure and keep them flat. If they try to speak and their voice is affected, the pressure is correctly applied.
5. While maintaining shoulder pressure, grab the opponent's tricep and slide your knee through as previously demonstrated, keeping your elbow tight to your body.
6. Back up slightly, secure a cross face, and apply shoulder pressure. Bring your knee to the opponent's hip, then remove the head grip, place your hand on the mat, and transition to side control.
7. Ensure your weight is distributed on your heel and toes to maintain the correct position and prevent the opponent from securing a deep underhook.
8. Keep your movements tight and controlled, preventing the opponent from moving and securing grips. If necessary, adjust your grip on their pants to ensure a tight hold.
9. As you transition to side control, maintain the grip on the opponent's pants and clamp down, ensuring a tight and controlled pass.
