SAFETY: North-South Choke from Reverse Scarf targets the Neck (Carotid Arteries). Risk: Loss of consciousness from bilateral carotid compression. Release immediately upon tap.
The North-South Choke from Reverse Scarf Hold is a high-percentage blood choke that exploits the unique reverse orientation of the scarf hold position to create a seamless transition into bilateral carotid compression. Beginning from reverse scarf hold, where the attacker already faces the opponent’s legs with heavy chest pressure established, the attacker threads their choking arm beneath the opponent’s neck and shifts their hips toward a north-south alignment. This transition leverages existing control and pressure to set up one of the tightest chokes available from top position.
The mechanics of this choke create a particularly effective strangling angle. The attacker’s bicep compresses one carotid artery while their chest and shoulder drop onto the opposite side of the neck, creating bilateral compression that produces rapid unconsciousness when locked correctly. The reverse scarf hold starting position offers a significant tactical advantage over entering the north-south choke from standard north-south, as the opponent’s arm is already trapped and their defensive framing options are severely compromised before the choke is even initiated.
Strategically, this submission serves as the primary threat from reverse scarf hold, forcing the bottom player into a defensive dilemma: protect the neck and concede positional advancement, or maintain frames against the pin and risk the choke. This dilemma creation makes the reverse scarf hold significantly more dangerous when the top player has developed proficiency with the north-south choke finish, transforming an often-overlooked transitional pin into a lethal submission platform.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Loss of consciousness from bilateral carotid compression | CRITICAL | Minutes to hours for full cognitive recovery; medical evaluation required if unconsciousness exceeds 10 seconds |
| Tracheal damage from improper technique applying pressure to windpipe instead of carotid arteries | High | 1-4 weeks depending on severity; may require medical attention for swelling or difficulty swallowing |
| Cervical spine strain from excessive neck cranking or lateral pressure during choke application | Medium | 3-14 days with rest and appropriate treatment |
Application Speed: SLOW and progressive. Blood chokes can cause unconsciousness in 4-8 seconds once locked. Never jerk or spike the choke. Apply pressure gradually and give your partner adequate time to tap. In training, pause briefly after initial engagement to allow recognition and tap response.
Tap Signals:
- Verbal tap (saying ‘tap’ or any distress signal)
- Physical hand tap on partner, own body, or mat
- Physical foot tap on mat or partner with either leg
- Any unusual vocalization, gurgling, or distress sound indicating inability to verbally tap
Release Protocol:
- Release ALL pressure immediately upon any tap signal - do not wait to confirm
- If partner goes limp or stops resisting unexpectedly, release immediately and check consciousness
- If in doubt about whether a tap occurred, release - position can always be re-established
- After release, maintain awareness of partner’s consciousness and breathing for 15-30 seconds
Training Restrictions:
- Beginners should practice positioning and mechanics only without applying full choking pressure until instructor approval
- Never apply this choke at full speed or force during drilling - save intensity for controlled positional sparring
- Partners with neck injuries, cardiovascular conditions, or blood pressure issues should avoid this technique entirely
- Always train with a qualified instructor present when first learning this choke

Playing as Attacker
Key Principles
-
Thread the choking arm deep beneath the opponent’s neck before committing to the hip transition - depth of the arm determines choke tightness
-
Maintain continuous chest pressure throughout the entire transition from reverse scarf to north-south alignment to prevent defensive frame creation
-
The finish comes from shoulder drop and chest compression against the neck, not from arm squeezing - use structural pressure over muscular effort
-
Control the opponent’s far arm throughout to prevent them from framing against your chest or creating space during the hip transition
-
Drop your head to the mat on the opposite side of the choking arm to lock the shoulder into the neck and complete bilateral compression
-
Sprawl your legs backward and drive hips forward to increase pressure through the choking structure without lifting your chest off the opponent
Execution Steps
-
Consolidate Reverse Scarf Hold Control: Ensure your chest pressure is heavy on the opponent’s upper chest with their near arm trapped tightl…
-
Control the Far Arm: Use your far hand to pin the opponent’s far arm to the mat or across their body. This prevents them …
-
Thread Choking Arm Beneath the Neck: Slide your near arm (the arm closest to the opponent’s head) beneath their neck from the side, drivi…
-
Begin Hip Transition to North-South: While maintaining the arm beneath the neck, begin shifting your hips from the reverse scarf hold ang…
-
Drop Shoulder and Head to Lock Position: As you reach north-south alignment, drop your shoulder on the choking-arm side directly into the opp…
-

Common Mistakes
-
Threading the choking arm too shallow beneath the neck, with forearm resting on chin or jaw rather than deep against carotid
- Consequence: Creates a crank or jaw pressure rather than a blood choke, causing pain without effective arterial compression. Opponent can endure the discomfort and work escape sequences while the attacker wastes energy squeezing ineffectively.
- Correction: Drive the arm deep until your bicep makes direct contact with the side of the neck at carotid level. Your elbow should pass completely to the far side of their neck before you begin the grip lock.
-
Lifting chest pressure off the opponent during the hip transition to north-south
- Consequence: Creates space for the opponent to insert frames, turn their body, or begin hip escaping before the choke is locked. The transition moment is when the opponent is most likely to escape.
- Correction: Keep your weight driving downward through your chest throughout the entire hip transition. Walk your feet in an arc while your upper body maintains continuous pressure. Think of your chest as glued to their torso.
-
Attempting to finish the choke by squeezing with arm strength rather than using shoulder and hip pressure
- Consequence: Arms fatigue rapidly, the choke lacks sufficient compression to cause arterial occlusion, and the attacker burns energy without achieving the finish. Arm squeezing also tends to lift the chest, reducing overall pressure.
- Correction: Focus on dropping your shoulder into the neck and driving your hips forward to create structural compression. The arms lock the position in place, but the finishing pressure comes from your body weight and skeletal alignment.
Playing as Defender
Key Principles
-
Recognize the choke setup at the earliest possible stage - the arm threading beneath your neck is the primary alarm signal that demands immediate defensive response
-
Protect your neck proactively with chin tuck and shoulder shrug before the attacker initiates the thread, making their entry path as narrow as possible
-
Create frames against the attacker’s chest during the hip transition phase when their pressure momentarily shifts, exploiting the movement gap for escape
-
Fight the choking arm grip before it locks rather than after - preventing the grip lock is far easier than breaking it once established
-
Use the attacker’s hip transition movement as your escape trigger, timing your bridge or hip escape to coincide with their weight redistribution
-
Tap early and tap decisively when caught - this choke produces unconsciousness in seconds and training is not worth risking injury or blackout
Recognition Cues
-
Attacker’s near arm begins sliding beneath your neck from the reverse scarf hold position, moving from arm control toward your throat
-
Attacker shifts their hips and begins walking their feet in an arc, transitioning from reverse scarf hold angle toward north-south alignment
-
Attacker’s shoulder drops heavy onto the side of your neck as they complete the transition, creating increasing lateral neck pressure
-
Attacker releases control of your near arm to use both hands for the choke setup, creating a brief defensive window
-
Attacker’s chest pressure shifts from your torso toward your head and neck area as they reposition for the choke angle
Escape Paths
-
Create frames against attacker’s chest and hip escape laterally to recover half guard before the choke grip is locked, using the attacker’s hip transition as your escape timing window
-
Bridge explosively toward the attacker during their hip transition phase to create a scramble opportunity and prevent them from settling into north-south choking alignment
-
Hand fight the choking arm to prevent depth beneath the neck, then use freed near arm to create frames and work standard reverse scarf hold escapes
