Hook Sweep: Inverted Arm Lock

Executing the Twist Sweep to off-balance an opponent can lead to advantageous sequences, even if the sweep itself is not successful. When an opponent lands in half guard, an initial movement may not result in a sweep, but it can cause their weight to shift, creating an opportunity to escape in the opposite direction.

1. As the opponent's weight bounces, use that moment to create a hook with your leg.
2. Begin lifting with the hook, and as you create space, move your bottom leg to the opponent's far hip.
3. Release the hook and transition your hands to the opponent's tricep, just above the elbow, while the other hand frames against their shoulder to prevent internal rotation.
4. Place your second foot high on the opponent's ribs or hip, close your knees, and angle your hips towards the direction the opponent's elbow is pointing.
5. Use both hands to secure the opponent's arm, ensuring that your armpit bites down on their hand rather than the wrist to prevent them from spinning their elbow.
6. Control the arm just above the elbow, below the tricep, with a tight grip of your fingers, leaving a mark on the opponent's arm.
7. Use one leg to prevent the opponent's weight from coming back and the other to stop their shoulder from dropping.
8. Finish the arm lock by keeping the opponent on the other side of your knees and using your hips to apply pressure.

This technique emphasizes the importance of connecting movements in Brazilian Jiu-Jitsu and using the opponent's reactions to set up submissions like the inverted arm lock.
