North-South Choke

What This Is

The north-south choke is a vascular choke applied from north-south position — the attacking player is perpendicular to the opponent’s body, chest against the opponent’s face or chest, facing the opponent’s feet. One arm wraps around the far side of the neck (under the opponent’s far arm), and the other arm scoops under the opponent’s head. The choke is completed by rotating the body weight toward the opponent’s head while pulling the head into the choking arm.

The north-south choke is mechanically subtle: it is not a squeeze in the conventional sense. The finish is created by the rotation of the attacking player’s body weight — the body drops toward the head while the choking arm maintains its position. This rotation creates the compression rather than direct arm force. Understanding this distinction is what separates a functional north-south choke from an ineffective squeeze.

The north-south choke is also available from the back crucifix position in an inverted configuration, and as a transition from the arm triangle angle walk that overshoots to north-south.

The Invariable in Action

The bilateral compression in the north-south choke is created differently from most other chokes: the choking arm creates compression on one carotid, and the body weight rotation of the attacking player’s chest and shoulder creates compression on the other side. There is no secondary arm compression — the body itself is the second compression surface. This is why the rotation is the finish, not the squeeze.

The body weight component of the north-south choke depends entirely on chest-to-face contact. If the attacking player sits up or creates space between their chest and the opponent’s face, the body weight rotation cannot apply force to the neck. The connection must be maintained throughout the finish motion. This is also what makes the north-south choke position-dependent — it requires the attacker to be at a specific height above the opponent’s head.

The north-south position creates a pin as well as a choke opportunity. The chest-to-face connection and the arm under the head prevent the opponent from rotating or posting to escape. The north-south choke exploits this pinning quality — the opponent cannot move their head out of the compression path because their movement is already restricted by the pin.

The Grip

The north-south choke grip:

Choking arm (far-side wrap): From north-south position, the attacking arm wraps under the far arm of the opponent and around the far side of the neck. The arm goes under the opponent’s arm (threading from outside to inside at the near arm’s armpit level), continues around the far side of the neck, and the forearm or bicep positions against the far carotid.

Scooping arm (near-side under head): The opposite arm slides under the opponent’s head, with the hand near the opponent’s far ear or neck. This arm scoops the head — it lifts and positions the head for compression rather than squeezing it. The forearm of this arm is the surface that drives the head into the choking arm when the rotation occurs.

The grip lock: The two arms connect — the choking arm’s hand grips the scooping arm’s hand or forearm near the opponent’s head. This creates a locked frame around the opponent’s head and neck.

Chest position: The attacking player’s chest is pressed down against the opponent’s face and neck. The chest stays in contact throughout — this is the body weight component that creates bilateral compression when the rotation occurs.

The Scoop Mechanic

The scoop is the most technically specific element of the north-south choke and the element most often missing in unsuccessful attempts.

What the scoop does: The scooping arm (under the head) lifts and drives the opponent’s head toward the choking arm. This is not a squeeze — it is a positioning action that brings the head into the compression zone of the choking forearm. Without the scoop, the head can move away from the choking arm, and the choke does not close bilaterally.

The direction: The scoop drives the head toward the choking arm side — the far side. The opponent’s head is brought toward the choking arm’s forearm, and simultaneously the body weight rotates toward the head. These two forces (head toward the arm, body weight toward the head) create the bilateral compression from opposite directions.

The common error: Squeezing the scoop arm upward rather than driving the head toward the choking arm. Squeezing upward creates airway pressure but not carotid compression. The lateral drive toward the choking arm is what creates the carotid compression on that side.

The Finish

The north-south choke finish is primarily a body weight rotation — not an arm squeeze:

The rotation: With the grip locked and the chest connected to the opponent’s face, the attacking player rotates their body weight toward the opponent’s head — dropping the chest and shoulders in the head direction. This rotation puts the attacking player’s weight through the opponent’s neck and jaw area, creating compression against the choking arm from above.

The simultaneous scoop: While the body rotates toward the head, the scooping arm drives the head into the choking arm. These two forces are simultaneous — the body weight comes from above, the scoop drives the head from below, and the choking arm is the static surface that the head is driven into.

Why this works: The choking arm creates pressure on the far carotid. The body weight rotation and scoop create pressure on the near carotid and jaw from above. The head cannot move away from either pressure because it is locked between the two forces. Bilateral carotid compression is achieved.

Duration: The north-south choke, when correctly applied, completes quickly. The bilateral compression does not require the opponent to endure it for a long time — unconsciousness arrives rapidly when the rotation and scoop are correct.

Setup and Entry

From North-South Position

The direct entry. From north-south pin, the choking arm threads under the far arm and around the neck, and the scooping arm slides under the head. The north-south position’s natural weight and chest contact set up the finish conditions immediately.

From Side Control (Angle Walk Overshoot)

When walking to the arm triangle finish angle, if the walk continues past 45 degrees toward north-south, the arm triangle transitions to a north-south choke opportunity. The arm triangle lock can convert — the attacking arm over the neck and the supporting arm under the head already approximate the north-south choke structure. Completing the walk to north-south and adjusting the grip completes the conversion.

From the Back Crucifix (Inverted)

From the back crucifix position, inverting the body — rolling so the head points toward the opponent’s legs — creates a north-south choke from an inverted angle. The choking arm that was controlling the far arm from the crucifix becomes the choke arm from the inverted position. This is an advanced transition requiring specific back crucifix mechanics. See: Back Crucifix.

From the Front Headlock (Walk to North-South)

From the front headlock ground control, walking the body past the opponent’s head toward north-south position while maintaining the head control can set up the north-south choke grip. The front headlock pressure walking provides the momentum for the north-south arrival.

Position Requirements

• North-South (Top) — Primary position. Chest-to-face, arms available for wrap and scoop.
• Side Control (to north-south walk) — Via angle walk overshoot from arm triangle position.
• Back Crucifix — Via body inversion. Advanced entry.
• Front Headlock (Ground) — Via walking forward past the opponent’s head to north-south.

Defence and Escape

Priority 1 — Bridge toward the far arm wrap: As the choking arm threads under the far arm, the defender bridges toward that arm, rolling to face the attacker. This can prevent the thread from completing and converts the position to a guard recovery or scramble.

Priority 2 — Prevent the chest connection: The body weight component of the north-south choke requires chest-to-face contact. Creating distance by bridging or turning prevents the chest from connecting. This must happen early — before the scoop and rotation begin.

Priority 3 — Prevent the scoop from driving the head: When the scooping arm slides under the head, the defender must tuck their chin and drive their head toward the mat. This prevents the head from being driven into the choking arm’s compression zone. Chin tuck plus head drive toward the mat is the specific defence against the scoop.

Priority 4 — Tap when rotation begins: Once the body rotation begins with the grip locked and the scoop driving the head, the finish is imminent. Tap as the compression increases — the north-south choke reaches its conclusion rapidly once the rotation is committed.
