### Z-Guard Control
#### Overview
The Z-Guard, often referred to as the Knee Shield, is a variation of the Half Guard position. It's a powerful tool in Brazilian Jiu-Jitsu for controlling an opponent while setting up sweeps or submissions. The position provides excellent defensive capabilities while allowing for offensive opportunities.
#### Position: Half Guard
The Z-Guard is usually utilized from the Half Guard position. It involves creating a barrier with your shin across the opponent's torso, often resting your foot on the opponent's hip, known as the "knee shield."
#### Japanese Name
- **Z-Guard Control**: This technique doesn't have a widely recognized Japanese name attributed to it.
#### Control Method
1. **Establish Half Guard:*
- Begin in Half Guard with your opponent's right leg trapped between your legs. Ensure your right hand secures an underhook if possible.
2. **Create a Frame with the Knee Shield:*
- Position your left shin diagonally across your opponent's torso, placing your left foot on their right hip. This is your knee shield.
- Push with your left knee to create space and maintain distance.
3. **Protect Your Upper Body:*
- Use your left arm to block your opponent's chest or shoulder. This helps prevent them from closing the distance and eliminates pressure.
4. **Control the Head or Arm:*
- Control your opponent's head with your right arm or look for wrist control to prevent them from attacking or achieving shoulder pressure.
5. **Adjust Your Angle:*
- As you apply pressure with the knee shield, adjust your hips towards their trapped leg for better control and to create angles for transitions or submissions.
#### Offensive Options
- **Sweep Setups:*
- Utilize the space and leverage created by the knee shield to execute sweeps such as the pendulum sweep or the old school sweep.
- **Submissions:*
- Transition to a triangle choke or setup arm drags leading to back control.
- **Transitions:*
- Consider transitioning to the deep half guard or reducing space for attacks from the full guard.
#### Defensive Potential
- The Z-Guard acts as a primary defense against knee-cut passes while offering opportunities to disengage and reset your guard.
