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.
The North-South Choke from Shoulder of Justice leverages the intense jaw pressure already established in the Shoulder of Justice position to seamlessly transition into one of the highest-percentage blood chokes in grappling. Unlike entering the North-South Choke from standard side control or north-south, this variation uses the opponent’s compromised defensive structure—head turned away, near arm trapped, posture broken by sustained pressure—to thread the choking arm under the neck before the defender recognizes the threat.
The setup begins with the cross-face arm sliding from shoulder pressure into an underhook beneath the opponent’s neck while the attacker walks their hips toward the head. The transition itself maintains constant pressure, preventing the critical window where defenders typically insert frames or recover head position. Once the gable grip locks and the hips sprawl past the opponent’s head, the choke compresses both carotid arteries through the combined mechanics of arm squeeze, chest-to-shoulder pressure, and hip sprawl.
This submission chain is particularly effective because the Shoulder of Justice creates a dilemma: endure the jaw pressure or react defensively. Both options feed directly into the North-South Choke entry, making it a natural complement to the pressure-based control strategy that defines the Shoulder of Justice position.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Carotid artery compression leading to loss of consciousness | High | Immediate recovery if released promptly; potential for longer-term effects if held after unconsciousness |
| Tracheal compression and windpipe damage from misaligned grip | Medium | 1-2 weeks with proper medical attention |
| Cervical spine stress from improper release or forced neck positioning | CRITICAL | Weeks to months depending on severity |
| Neck strain from explosive bridging attempts under choke pressure | Medium | 3-7 days |
Application Speed: SLOW and progressive - 3-5 seconds minimum to allow partner to recognize the danger and tap before full compression
Tap Signals:
- Verbal tap or verbal submission
- Multiple rapid hand taps on opponent’s body
- Multiple rapid foot taps on the mat
- Any distress signal including body convulsions or going limp
- Loss of resistance indicating possible unconsciousness
Release Protocol:
- Immediately release arm pressure and unlock gable grip upon any tap signal
- Roll off opponent’s head and neck area completely without jerking their neck
- Allow opponent to recover in side-lying position with airway clear
- Monitor for signs of consciousness and normal breathing patterns
- If opponent is unconscious, place in recovery position and alert medical staff immediately
Training Restrictions:
- Never apply explosive or jerking pressure to the neck during the choke transition
- Always ensure partner has clear tap access with at least one hand throughout the sequence
- Never hold the choke after partner taps or goes limp under any circumstances
- Beginners should practice only the positional transition and grip placement without applying choking pressure
- Never use competition speed or full pressure in training—apply progressively and give time to tap

Playing as Attacker
Key Principles
-
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

Common Mistakes
-
Lifting shoulder pressure during the arm threading transition
- Consequence: Creates space for the defender to insert frames, reposition their head, and recognize the choke setup, killing the attack before it begins
- Correction: Maintain constant chest-to-body contact throughout the entire grip change by sliding the arm while keeping your torso weight on the opponent
-
Threading the arm too shallow around the neck
- Consequence: Produces a trachea choke rather than a blood choke, which is slower, more painful, gives more escape time, and is less effective against determined opponents
- Correction: Drive the forearm deep under the neck past the Adam’s apple to position at the jaw line where carotid arteries are most superficial before locking the gable grip
-
Rushing the hip walk with large movements
- Consequence: Opponent recognizes the transition, inserts frames during the pressure gap, and the choke attempt fails with a return to neutral side control
- Correction: Walk hips in small incremental steps maintaining pressure at each position, disguising the transition within normal positional adjustments
Playing as Defender
Key Principles
-
Recognize the grip transition early—the moment shoulder pressure shifts to arm threading is your highest-percentage defensive window
-
Insert compact forearm frames against the threading arm before it passes under your neck to block the choke path
-
Fight the grip before it locks—once the gable grip is secure, escape probability drops dramatically and tapping becomes the safe choice
-
Create hip distance through well-timed shrimping when the attacker commits weight toward your head during the transition
-
Keep elbows tight to your body to create structural barriers that prevent the arm from sliding deep under your neck
-
Turn your chin toward the choking arm side to compress the space available for arm threading
Recognition Cues
-
Shoulder pressure shifts from static jaw compression to a sliding movement along the side of your neck toward an underhook
-
Opponent begins walking their hips toward your head in small incremental steps rather than maintaining hip-to-hip connection
-
The cross-face arm starts threading and circling beneath your neck rather than maintaining static downward shoulder pressure
-
Weight distribution noticeably shifts from your hip line toward your head and shoulder area
-
Opponent’s free hand reaches toward the threading arm to establish a grip connection around your neck
Escape Paths
-
Insert forearm frames during the arm threading phase and hip escape to recover half guard or closed guard before the gable grip locks
-
Turn chin toward the choking arm to compress the threading space, then shrimp away to create distance for guard recovery
-
Bridge explosively during the hip walk transition to disrupt the attacker’s base and create a scramble back to neutral position
