Headquarters Pass BJJ: White Belt Biomechanics Guide

1. Grip: Establish a deep cross-face grip with your right hand on their left carotid sinus (throat) and your left hand on their left shoulder or upper bicep.
2. Hip Angle: Lower your right hip towards the mat, creating a 45-degree angle between your torso and their body.
3. Knee Drive: Drive your right knee forward, aiming it directly at the crease of their left hip socket.
4. Base Adjustment: Widen your base slightly by planting your left foot firmly on the mat, ensuring stability.
5. Head Pressure: Apply downward pressure with your head into their left shoulder, forcing their body to turn away from you.
6. Weight Transfer: Shift your weight forward onto your right knee and your head, compressing their upper body.
7. Hip Cut: Continue to 'cut the corner' with your hips, moving your right hip past their hip line as you advance your chest to the mat.
8. Leg Placement: Once their hip is cleared, bring your left leg to their hip to establish side control, maintaining head and arm control.

• Trying to force the pass by pushing their legs apart with your hands: This can lead to a wrist sprain due to hyperextension if they resist strongly, or a shoulder impingement if you lose balance. The correct action is to use hip pressure and head control to break their posture.
• Driving your knee directly into their stomach instead of their hip crease: This can cause a knee ligament tear (ACL/MCL) if their body pivots unexpectedly, or a hip flexor strain for you. Your knee should drive into the hip socket to facilitate the hip cut.
• Lifting your head and losing cross-face pressure: This allows them to re-establish guard or create space, potentially leading to a sweep or submission attempt on you. Always maintain firm head and cross-face pressure to control their upper body.

1. Solo Movement: Practice the hip angle, knee drive, and hip cut motion without a partner. 10 reps per side.
2. Static Partner Drill: With a compliant partner, execute the grips and weight transfers from side control, focusing on the hip cut. 5 reps per side.
3. Light Pressure Drill: The partner offers minimal resistance to the hip cut, allowing you to feel the movement and weight transfer. 10 reps per side.
4. Guard Break and Pass: Partner attempts to hold guard. Focus on breaking posture and executing the pass. 5 reps per side.
5. Controlled Live Rolling: Execute the Headquarters Pass against a partner who is actively defending but not attacking submissions. 3 rounds.
6. Full Resistance Rolling: Attempt the Headquarters Pass during live rolling with full resistance from your partner. 5 rounds.

• WHEN TO ATTEMPT:
• When your opponent is in a tight closed guard and you have good posture control.
• When your opponent attempts a spider guard or de la riva guard and their hips are slightly extended.
• When you have established knee-on-belly and are looking to transition to a more dominant passing position.
• PRIMARY COUNTERS:
• Frame and Hip Escape: If the opponent initiates the pass, create a frame with your forearm between their chest and your hips, and simultaneously hip escape to create space and prevent the hip cut. This requires precise timing and pressure distribution.
• Underhook and Shrimp: If they secure the cross-face, fight for an underhook on their far arm and shrimp your hips away, creating angles to potentially reverse the position or regain guard. This is a reactive defense.
• Guard Retention/Leg Pummel: If they begin to cut the corner, actively pummel your legs to re-establish a guard or half-guard structure, preventing them from clearing your hips. This focuses on maintaining your defensive structure.
