SAFETY: North-South Choke from Side Control targets the Carotid arteries and trachea. Risk: Carotid artery compression leading to loss of consciousness. Release immediately upon tap.
Attacking with the North-South Choke from Side Control requires mastering a seamless transition that doubles as a submission entry. The attacker begins in standard side control with a strong crossface and near-side underhook or hip block, then initiates a controlled walk toward north-south while threading the choking arm underneath the opponent’s neck. The critical skill is maintaining constant chest pressure throughout the transition so the opponent cannot create space or insert defensive frames. The finish relies on bilateral carotid compression — the choking arm handles one side while the shoulder and body weight handle the other — making it one of the tightest blood chokes available from top position. Timing the arm thread with the body rotation is what separates successful attempts from those that stall in a loose north-south position.

Key Attacking Principles
What are the key principles for executing North-South Choke from Side Control?
- Maintain constant chest-to-chest pressure throughout the entire transition from side control to the choking position, never allowing space for the opponent to insert frames
- Thread the choking arm deep under the opponent’s neck before committing to the north-south rotation — a shallow arm produces a crank, not a choke
- Use the crossface hand to control the opponent’s far-side head and jaw, preventing them from turning toward you during the transition
- Sprawl your legs wide and drive your hips to the mat once in position, anchoring your body weight through the shoulder into the neck
- Squeeze the choking arm elbow tight to your own body to close the gap between your bicep and forearm around the neck
- Keep your head low and tight against the opponent’s far-side hip to prevent them from creating rotational escape angles
Prerequisites
What do you need before attempting North-South Choke from Side Control?
- Established side control with stable crossface and hip-to-hip connection preventing opponent from creating space
- Opponent’s near-side arm controlled or pinned — either trapped under your body or pushed above their head so it cannot block the arm thread
- Head and neck access cleared by driving the crossface deep enough that the opponent’s chin is turned away, exposing the near-side neck
- Base secured with legs sprawled wide enough to maintain pressure during the rotational transition without being swept or rolled
Execution Steps
How do you execute North-South Choke from Side Control step by step?
- Establish dominant side control: Settle into a tight side control with your chest heavy on the opponent’s chest, crossface driving their chin away from you, and near-side hand blocking their far hip. Ensure your hips are low and heavy against their hips with no space between your bodies. Confirm the opponent’s near-side arm is not in a position to block your upcoming arm thread. (Timing: 5-10 seconds to settle and confirm control)
- Clear the near-side arm: Use your crossface hand or a quick push to move the opponent’s near-side arm above their head or trap it against their body with your weight. If they are framing against your hip, swim your underhook deeper and use your shoulder pressure to collapse the frame. The near-side arm must be neutralized before you begin the transition or it will block the choking arm from threading under the neck. (Timing: 3-5 seconds)
- Thread the choking arm under the neck: Slide your crossface arm deeper so that your bicep and forearm wrap around the opponent’s near-side neck from behind. Your palm should face the mat as you thread, and your elbow should pass under their chin toward the far side of their neck. Keep your chest heavy on their face and chest throughout this motion — if you lift up to create space for the thread, the opponent will turn in and recover guard. (Timing: 2-3 seconds — must be smooth, not rushed)
- Begin walking toward north-south: With the choking arm threaded, start walking your body toward the north-south position by stepping your far-side leg over the opponent’s head while keeping your chest glued to their upper body. Your free hand posts on the mat for balance on the far side. Move in small controlled steps rather than one large leap — each step should increase the choking pressure as your shoulder rotates into the neck. (Timing: 3-5 seconds of controlled movement)
- Lock the choking position: Once your body reaches approximately a 45-degree angle relative to the opponent’s body, drop your shoulder weight directly into the choke. Squeeze your choking arm tight by pulling your elbow toward your own ribs, closing the gap between your bicep and forearm around the neck. Your free hand grabs your own thigh or reaches under the opponent’s far-side arm for additional leverage. Sprawl your legs wide behind you and drive your hips to the mat. (Timing: 1-2 seconds to lock position)
- Apply finishing pressure: With everything locked in position, apply the finish by simultaneously dropping your shoulder weight into the neck, squeezing the choking arm toward your ribs, and sprawling your hips flat to the mat. The bilateral compression comes from your bicep on one carotid and your shoulder and pectoral on the other. Hold steady progressive pressure — do not pulse or jerk. The opponent should feel the blood choke take effect within 3-5 seconds if the position is correct. Monitor for tap signals continuously. (Timing: 3-8 seconds for the tap, apply slowly and progressively)
- Adjust if choke is not tight: If the opponent is not tapping after 5 seconds, micro-adjust by walking your hips slightly more toward north-south to change the shoulder angle, or re-grip your choking arm deeper under the neck. A common fix is turning your choking-side wrist so your palm faces the ceiling, which rotates the radius bone into the carotid more effectively. If the choke remains loose after adjustments, you may need to release and re-establish side control rather than holding a poor position. (Timing: 2-5 seconds for adjustment, reassess)

Opponent Defenses
How might your opponent defend against North-South Choke from Side Control?
- Opponent turns into you and frames against your hips to prevent the north-south transition (Effectiveness: High) - Your Response: Abandon the choke attempt early and capitalize on their turn by switching to an arm triangle or darce choke, which become available when they turn into you. Alternatively, re-establish the crossface and settle back into side control before reattempting. → Leads to Side Control
- Opponent bridges explosively while you are mid-transition to create space and recover guard (Effectiveness: Medium) - Your Response: Drop your hips immediately and sprawl to absorb the bridge. If you maintain chest contact, the bridge will not generate enough space. If they do create a gap, quickly backstep your leg over to prevent the guard recovery and re-establish side control. → Leads to Closed Guard
- Opponent gets their near-side arm inside the choke to block the throat (Effectiveness: High) - Your Response: If the arm is partially blocking, use your free hand to peel it away by gripping the wrist and pushing it toward their hip. If the arm is fully inserted, abandon the choke — forcing it with the arm inside creates a crank rather than a clean choke and risks injury in training. → Leads to Side Control
- Opponent shrimps away and inserts a knee to recover half guard during the transition (Effectiveness: Medium) - Your Response: If you feel the knee entering, immediately drop your hip weight to pin it and walk back toward standard side control. Re-clear the leg before reattempting. Prevention is better — keep your hips low against their hips throughout the transition. → Leads to Side Control
