North-South Choke
North-south choke — the head closes into the attacker's armpit, palm-to-palm connect, and the body sinks to finish. Weight, not squeeze.

The north-south choke is a vascular choke applied from the north-south position — the attacking player faces the opponent’s feet, chest over the opponent’s head. The choking arm wraps around the neck so that the opponent’s head is closed into the attacker’s armpit: the armpit and chest close one side of the neck, and the biceps and forearm of the choking arm close the other. The free hand connects palm-to-palm with the choking hand, and the finish arrives from the body sinking low toward the opponent’s head.
The north-south choke is mechanically subtle. The finish is created by dropping the shoulders and hips — the body sinks low and drives in a straight line toward the opponent’s head while the arm structure holds its shape. The compression comes from body weight sinking, with minimal arm squeeze, and it builds gradually as the body settles. Understanding this distinction is what separates a functional north-south choke from an ineffective squeeze.
The inverted crucifix version is reached by rolling from the back crucifix and belongs to Crucifix North-South Choke, which is a separate instance. This page also arrives as a transition from the arm triangle angle walk that overshoots to north-south.
INV-S01Invariant "All strangles require compression on both sides of the neck simultaneously. Compression on one side only creates discomfort; compression on both sides interrupts blood flow."
Why it works hereThe north-south choke closes the neck between two body surfaces: the attacker's armpit and chest on one side, and the biceps and forearm of the choking arm on the other. The head is shut inside the armpit, so both carotids are loaded by the same structure. The finish force comes from the shoulders and hips dropping — body weight sinking in a straight line toward the head — with minimal arm squeeze. An arm squeeze on its own tends to collapse onto the airway and loads only one line of pressure.
See full invariant page → The bilateral compression in the north-south choke is created by a single wrapped structure: the armpit and chest close one side of the neck, and the biceps and forearm close the other. The body is a compression surface, and the sink of the shoulders and hips is what delivers force through it. This is why the sink is the finish, with the arms holding shape rather than squeezing.
INV-01Invariant "Body-to-body connection at the relevant contact point eliminates structural space and transfers weight, preventing the opponent from generating independent movement. The contact point varies by position — chest-to-chest in pins, chest-to-back in back control, hip-to-hip in leg entanglements, shoulder-to-back in turtle attacks — but the mechanical truth is identical regardless of where the connection is made."
