The north-south choke runs on body weight and shoulder pressure, not grip strength, which is exactly why Marcelo Garcia made it work against much bigger opponents.

The north-south choke is a blood choke. You apply it from north-south position. Your chest sits over your opponent's stomach. Your head points toward their legs. The choke relies on shoulder and forearm pressure, not grip strength. Marcelo Garcia built much of his game around this exact detail. He was one of the smallest elite black belts in history, and this choke still worked against much bigger opponents.

The choke doesn't rely on squeezing your arm. It relies on your body weight. That weight travels through your shoulder into their neck. Heavier pressure finishes the choke. A tighter grip does not.
Turn onto your side right away. Frame against your opponent's hip. Staying flat on your back makes the choke easier to finish. Turning removes the angle they need.
This choke works in both settings. In the gi, some grapplers add a collar grip for extra control. In no-gi, the same shoulder-pressure mechanics apply without any fabric involved.
For more finishes from top pressure positions, see our rear naked choke guide and guillotine choke guide.
Likely because you are relying on arm strength instead of driving your shoulder weight down into the choking arm. Pressure, not grip, is what finishes it.
Yes. The shoulder-pressure mechanics are identical with or without a gi, since the choke does not depend on fabric grips.
Yes. It is a blood choke rather than a joint lock, so it is legal at every belt level under IBJJF rules.
Control their hips before you finish, not just their neck. Walking your hips toward their head as you apply the choke removes the space they need to turn onto their side.
