SAFETY: North-South Choke from Shoulder of Justice targets the Carotid arteries. Risk: Carotid artery compression leading to loss of consciousness. Release immediately upon tap.
Executing the North-South Choke from Shoulder of Justice requires precise timing of the grip transition from cross-face shoulder pressure to neck encirclement. The attacker must maintain constant pressure throughout the transition to prevent the defender from recognizing the shift and inserting defensive frames. The key advantage of this entry is that the Shoulder of Justice has already broken the opponent’s defensive posture, turned their head, and restricted their near arm, creating ideal conditions for threading the choking arm beneath the neck. Success depends on smooth, incremental hip walking toward the north-south angle combined with progressive arm deepening around the neck before committing to the gable grip lock and finishing sprawl.

Key Attacking Principles
What are the key principles for executing North-South Choke from Shoulder of Justice?
- Maintain constant chest-to-body pressure during the entire grip transition from shoulder pressure to neck encirclement
- Walk hips toward the head in small incremental steps rather than one large movement that alerts the defender
- Thread the choking arm deep beneath the neck past the trachea before committing to the gable grip lock
- Lock the gable grip tight against your own chest at the jaw line to maximize bilateral carotid compression
- Sprawl hips completely past the opponent’s head and drop chest weight onto their shoulder line before squeezing
- Squeeze elbows together using chest and back muscles rather than pulling with arms to generate sustainable choking pressure
Prerequisites
What do you need before attempting North-South Choke from Shoulder of Justice?
- Established Shoulder of Justice position with sustained jaw pressure turning opponent’s head away
- Opponent’s near arm controlled or trapped to prevent frame insertion during the threading phase
- Stable base with hips connected to opponent’s hip line and far knee posted wide for balance
- Cross-face arm positioned at the shoulder-neck junction ready to transition from pressure to underhook
- Opponent’s defensive structure compromised by sustained pressure with head turned and posture broken
Execution Steps
How do you execute North-South Choke from Shoulder of Justice step by step?
- Confirm Shoulder of Justice Control: Verify your Shoulder of Justice is fully established with shoulder blade driven into the opponent’s jaw at a 45-degree angle toward their far shoulder. Hips must be heavy on their near hip line with near arm controlled or pinned. Confirm your base is stable with far knee posted wide before initiating the choke transition. Do not begin the threading if your position is not consolidated. (Timing: 2-3 seconds to confirm position stability)
- Begin Threading the Choking Arm: While maintaining chest-to-body contact and downward pressure, begin sliding your cross-face arm from the static shoulder pressure position to thread it beneath the opponent’s neck. Use the angle created by their turned head as the entry path for your forearm. This movement must be gradual and disguised within your normal pressure adjustments to avoid alerting the defender to the grip change. (Timing: 2-4 seconds for smooth arm insertion)
- Walk Hips Toward Head: Take small incremental steps with your hips toward the opponent’s head, shifting your weight progressively from a side-control angle toward the north-south angle. Each step should deepen your arm position around the neck while keeping your chest heavy on their torso. Do not lift your hips or create any gap between your body and theirs during this walk—every step maintains or increases pressure. (Timing: 3-5 seconds of incremental hip movement)
- Secure the Gable Grip: Once your threading arm has passed sufficiently around the neck and past the trachea, bring your free hand to meet it and secure a palm-to-palm gable grip pulled tight against your own chest. The grip should sit at the base of the opponent’s jaw near their ear where the carotid arteries are most superficial. Avoid gripping too low on the neck where compression targets the trachea rather than the arteries. (Timing: 1-2 seconds to lock grip securely)
- Complete the North-South Sprawl: Sprawl your hips past the opponent’s head while dropping your chest weight onto their shoulder line. Your body should arrive perpendicular to theirs with your head positioned near their far hip. Maintain the gable grip tight to your chest throughout the entire sprawl movement to prevent any gap between your arm and their neck that would relieve arterial compression. (Timing: 1-2 seconds for the sprawl completion)
- Apply Finishing Squeeze: Drive your elbows together toward each other while simultaneously dropping your shoulder weight downward and extending your hip sprawl further. The choke compresses both carotid arteries through the combined mechanics of arm squeeze, chest-to-shoulder pressure, and hip extension. Increase pressure progressively and smoothly over three to five seconds, giving your training partner time to recognize the choke and tap. (Timing: 3-5 seconds of progressive squeeze)
- Micro-Adjust if Needed: If the initial squeeze does not produce a tap within several seconds, make micro-adjustments without releasing any pressure. Walk your hips slightly to change the compression angle, tighten the grip closer to the jaw line where arteries are more accessible, or increase your sprawl to drive more body weight through the choking arms. Small positional adjustments often produce significant changes in choke effectiveness without requiring a full reset. (Timing: Ongoing adjustments as needed)

Opponent Defenses
How might your opponent defend against North-South Choke from Shoulder of Justice?
- Frame insertion with forearms before grip locks (Effectiveness: High) - Your Response: If opponent gets forearms between their neck and your threading arm, abandon the choke attempt and re-establish Shoulder of Justice pressure to reset. Re-apply jaw pressure to break their composure, then reattempt when they make a different defensive reaction. → Leads to Shoulder of Justice
- Bridge and turn toward the choking arm (Effectiveness: Medium) - Your Response: Ride the bridge by widening your base and dropping hips heavier. Use their turning momentum to accelerate your hip walk toward north-south. Their turn often deepens your arm position rather than creating escape space. → Leads to Shoulder of Justice
- Hip escape away creating distance during transition (Effectiveness: Medium) - Your Response: Follow their hip escape with your own hip movement, maintaining grip contact. If they create significant distance, transition to standard north-south control and attempt the choke from there. If grip is lost, return to side control and re-establish Shoulder of Justice. → Leads to Shoulder of Justice
- Pushing your head away with both hands to create space (Effectiveness: Low) - Your Response: Their hands on your head means their arms are extended and vulnerable. Maintain your threading arm position and use chest pressure to collapse their arm structure. Both arms on your head also means zero frame defense against the choke itself. → Leads to Closed Guard
