It looks like nothing — a top player squaring his chest over an upside-down opponent, hands clasped, barely moving — and it finishes in under ten seconds. For decades the north-south choke was written off as a heavyweight's accident, until Marcelo Garcia proved the strangle runs on angle, not mass. In 2025 a returning Garcia and a UFC champion both ended world-level fights with it.
On 7 June 2025, in the main event of UFC 316, Merab Dvalishvili defended the bantamweight title against Sean O'Malley for the second time. O'Malley had spent the build-up promising a different fight than their first meeting. He did not get one. Dvalishvili took him down, worked past his guard, and late in the third round settled his chest over O'Malley's face upside-down, clasped his hands, and dropped his shoulder into the side of O'Malley's neck.
O'Malley tapped. It was the first submission win of Dvalishvili's UFC career, and to most of the arena it looked like almost nothing had happened — no visible crank, no wrenched limb, just a heavy man lying still on top of another man for a few seconds until the fight was over.
That "almost nothing" is a north-south choke, and it is one of the fastest strangles in grappling. Applied correctly, the vascular version closes both sides of the neck's blood supply and drops an opponent in the neighborhood of ten seconds — one published estimate puts the average at 9.4 seconds once the choke is properly set. There is no long grind, no gradual fade the way a rear-naked choke can feel. The lights go out or the hand comes up.
For most of jiu-jitsu's history the move was treated as a curiosity, and a specific kind of curiosity: a big man's trick. The fighters who caught people with it — Jeff Monson foremost, a heavyweight whose name fans attached to the technique — were large and strong, and the choke seemed to work because their mass fell into it. Then a 77-kilogram Brazilian spent two decades finishing world-class opponents who outweighed him with the same strangle, and the "big man's move" explanation quietly collapsed.
This is a story about that strangle — how it works, why it reads as nothing, and why the smallest man in the room can be the most dangerous one holding it.
The north-south choke is the rare submission that gets weaker the harder you squeeze — it is finished by a hip sprawl and a dropping shoulder, and the grapplers who understand that can close it at any weight.
The north-south choke is not a modern invention, but it also has no single inventor on record. Its geometry comes straight out of judo's ground game: it closely resembles kuzure-kami-shiho-gatame, the "broken upper four-corner hold," one of the classical osaekomi-waza pins in which the top player controls from beyond the opponent's head with the two bodies reversed, chest to chest. Judo treated that configuration as a hold-down. The strangle hiding inside it — wrap the neck, drop the shoulder, sprawl — was folk knowledge that circulated for decades without a name, a system, or a face.
For most of jiu-jitsu's first several decades the position it lives in, north-south, was taught as a corridor between side control and the back rather than a place to finish. (bjj.media covers the pin itself in depth on the North-South page.) The choke was the sort of thing an experienced heavyweight would catch you with in a hard round and then struggle to explain, because he was not entirely sure what made it work.
The name most attached to it in that era belongs to Jeff Monson. Monson, a muscular heavyweight, hit the choke so often across a long professional career that the grappling public started calling it the "Monson choke." His build reinforced the reading everyone already had: the north-south choke was a strangle for big, strong men who could collapse a smaller opponent's neck under sheer shoulder and lat pressure. It looked like a compression finish — mass beating leverage.
The inflection point is Marcelo Garcia. A black belt under Fábio Gurgel at Alliance, Garcia built one of the most decorated competitive records in the sport — the most ADCC gold medals of any male competitor, with titles in 2003, 2005, 2007 and 2011 — competing the whole time as a middleweight who routinely gave up size in the open-weight brackets. His identity was submission-first, and the north-south choke became one of his signatures.
By his own account in his instructional material, Garcia did not design the choke in a lab; he found it in the training room and refined it until it worked on people who should have been too big for it. In doing so he inverted the folk wisdom. If a 77-kilogram man could tap heavyweights with the same strangle Monson was using, then mass was never the mechanism. The finish had to be a matter of angle, arm position and a specific downward sprawl — and once framed that way, it became teachable. Garcia eventually codified the whole approach in a dedicated instructional, The Complete North South Choke, on BJJ Fanatics, and the technique spread far beyond his own lineage into general no-gi curriculum.
One strangle. Decades as a big man's trick. One middleweight who proved it was geometry.
Start with what is actually being attacked, because almost every failed north-south choke misunderstands the target.
This is a blood choke, not an air choke. The goal is not to crush the windpipe — that is slow, painful, and defensible — but to close the carotid arteries on the sides of the neck and interrupt blood flow to the brain. When both carotids are shut, unconsciousness follows fast; the commonly cited estimate is under ten seconds. That single fact reorganizes everything about how the choke should be applied: you are not trying to make it hurt, you are trying to make it quiet. A north-south choke that has your opponent grimacing in pain is usually a choke that is on the trachea and going nowhere. A north-south choke that is working often produces no dramatic reaction at all — right up until the tap.
The finishing frame has three walls:
1. The choking arm. One arm wraps under and across the front of the opponent's neck. Your forearm lies across the throat and your own shoulder sits against the far side, so the meat of your forearm and the meat of your shoulder become the two clamping surfaces around the neck and jaw.
2. The opponent's own shoulder. This is the wall people forget. As you square up over the top of the head, the opponent's near shoulder is driven up toward their own ear, and that shoulder becomes the third surface pressing into their carotid. You are not choking with two arms; you are choking with your arm, your shoulder, and their shoulder, folded into the side of their neck.
3. The grip. Hands meet in a Gable grip — palm to palm, no interlaced fingers — cinched to shrink the loop. The fingers never leave the grip to grab cloth or reach; the grip is a fixed frame, and the finish comes from moving your whole body, not from re-gripping.
Here is the counter-intuitive core, and the single thing that separates people who finish this choke from people who merely hold it. You do not muscle the arms together. You drive your hips back and down and lower the choking-side shoulder into the neck. The sprawl is the engine. As your hips retreat and your shoulder drops, your bodyweight and posture fold the opponent's own shoulder into their carotid and tighten the frame around the far side. The arms hold their shape; the body does the work.
This is exactly why Garcia could finish opponents who outweighed him and why the choke was misread as a strength move for so long. A heavyweight can brute-force the compression, so when a heavyweight finishes it, the strength looks like the cause. But strength is a substitute for correct angle, not the source of the finish. Get the head placement, the shoulder line and the sprawl exact, and a middleweight closes it on a bigger, fresher opponent. If your arms are burning, your hips are in the wrong place.
There are two families. In the classic arm-out version, both of the opponent's arms are below the choke and the strangle is a pure carotid clamp. In the arm-in version — the one Garcia used to finish Masakazu Imanari at ONE 170 in January 2025 — one of the opponent's arms is trapped inside the choke, and its own shoulder is used to help wall off the neck, borrowing a little of a triangle's logic. Garcia teaches the arm-in as a way to finish precisely when an opponent defends a head-and-arm attack, because the defensive arm they gave you is now part of the strangle. It is not a different move so much as a way to keep finishing when the tidy arm-out picture is not available.
The choke is the second move, never the first. Before it, you have to solve the opponent's arms, because free arms frame into your hips, wedge across your throat, and manufacture the space to turn or shrimp out. Strong finishers pin the near arm — often by dropping their chest onto it and walking it down and away from the neck — before the choking arm ever slides in. Garcia's own detail is to push the opponent's arms down to expose the neck, then use chest pressure to keep them there. A north-south choke attempted with the opponent's arms still live is a north-south choke that funds their escape.
The most common entries are the natural ones. From side control you walk your body around the crown of the head into north-south and settle. From mount you can attack a head-and-arm strangle and, when it is defended, slide over the top into the choke — the exact chain Garcia ran against Imanari, mount to north-south. And the position hosts a second finish: with an arm isolated above the head, the kimura (ude-garami) is right there, so the opponent who buries an arm to stop the strangle can hand you the shoulder lock instead. The two threats cover each other.
In 2026 the north-south choke sits in an unusual spot: technically old, competitively rare for scoring reasons, and — for the first time — genuinely famous.
The rare-but-lethal character comes from the scoreboard. The position it finishes from is worth zero points under both IBJJF and ADCC rules, so a points-minded competitor has no reason to camp there. That means the choke shows up disproportionately in the environments that do not care about points: submission-only promotions, overtime rulesets, and the finish-hungry back half of ADCC brackets. When a tap is the only currency, a scoreless pin with a sub-ten-second strangle attached stops being a liability and becomes prime real estate. That is the environment a returning Marcelo Garcia stepped into at ONE 170, and it is why the choke has migrated out of his lineage into broad no-gi curriculum.
What changed most is visibility. For twenty years the north-south choke was an insider's technique — a thing Garcia did that most people could not reliably reproduce, and a thing a handful of heavyweights caught in the cage. In 2025 it reached the general MMA audience twice in five months: Garcia's comeback finish of Imanari at ONE 170 in January, and Merab Dvalishvili's title-retaining finish of Sean O'Malley at UFC 316 in June. Millions of casual fans watched a bantamweight champion win a headline fight with a strangle most of them had never seen and could not name. A move that spent decades being explained away as a big man's accident is now something a UFC broadcast has to teach on the fly.
The last change is pedagogical. Twenty years ago you reverse-engineered the choke from footage. Today it is a documented, drillable system with a dedicated instructional, a named arm-in variation, and a generation that learned it as a technique rather than stumbling into it. The position did not get more popular. The finish got teachable — and, briefly, televised.
Selecting dated instances in which the north-south choke did the deciding work, across grappling and MMA.
Garcia's return to competition after more than a decade away. He took Imanari down, passed to side control, climbed to mount, threatened a head-and-arm strangle, and when Imanari defended it, transitioned to north-south and finished with the arm-in choke before the midpoint of the match. A middleweight legend tapping a fellow legend with his signature strangle — and the clearest modern proof that the finish is angle, not mass.
A bantamweight title rematch. Dvalishvili controlled the grappling and finished O'Malley with a north-south choke at the end of the third round — the first submission win of his UFC career, in front of a mass pay-per-view audience. The single most-watched north-south choke in the technique's history, and the moment it entered casual-fan vocabulary.
An earlier, cleanly datable MMA finish from one of the sport's most persistent submission grapplers. Yahya secured the north-south choke inside the first round — an example of the technique working at the highest level of the cage a full decade before its 2025 mainstream moment.
Beyond individual bouts, the technique has a body-of-work signature in MMA that no single match captures: Jeff Monson caught the choke so often that it carried his name. That volume, more than any one finish, is what kept the "big man's move" reading alive until Garcia dismantled it.
White belt meets the north-south choke as the thing that keeps catching them when a heavier training partner settles on top after passing. The first lesson is not how to do it but how to recognize it early enough to defend — hands fighting to the hips, chin tucked, turning in before the shoulder drops.
Blue belt learns that it is a blood choke. The blue belt who muscles it, cranks the neck, and gets a grimace instead of a tap has not yet understood the target. The shift is realizing you are hunting the carotids, not the windpipe, and that a working choke is often a quiet one.
Purple belt starts finishing it — usually badly at first, by squeezing. The purple-belt breakthrough is the sprawl: the discovery that driving the hips back and dropping the shoulder does what the arms were failing to do, and that grip strength was never the missing piece.
Brown belt solves the arms. The brown belt clears and pins the near arm before the choking arm enters, chains the choke with the kimura so the defense to one is the entrance to the other, and stops telegraphing which is coming.
Black belt engineers the whole sequence. The black belt steers exchanges toward north-south on purpose — from a passed guard, from a defended arm-triangle in mount, from a scramble — reads which arm the opponent will surrender, and pre-selects arm-in choke, arm-out choke, or kimura before arriving. For the black belt the strangle is not a thing that happens to be available; it is a destination the exchange was pointed at three moves earlier.
1. Squeezing instead of sprawling. The defining error, and the source of the "only works for big guys" myth. Muscling the Gable grip tighter fatigues your arms and rarely closes the carotids. The finish is a hip sprawl back-and-down with the choking shoulder dropping into the neck. If your arms are burning, your hips are wrong.
2. Choking the windpipe. Riding the forearm across the trachea produces coughing, pain, and a stubborn opponent who does not pass out. The target is the sides of the neck, not the front. A correct north-south choke is a quiet choke; if it looks agonizing rather than sudden, it is on the wrong structure.
3. Reaching for the choke with the arms still free. Sliding the choking arm in before you have pinned the opponent's near arm hands them the frames and the space to turn out. Clear and staple the near arm first — chest down, walk it away from the neck — then insert the choke. The strangle is the second move.
4. Riding too high, chest off the chest. Weight up near the opponent's face with a gap under your sternum is the exact room they need to bridge and spin before you ever set the frame. The chest stays low and connected; the choke is finished from heavy, not from floating.
5. Bailing too early. Because the finish produces so little visible drama, newer players assume it "isn't working" and abandon it a second before it closes. This is a fast choke once the frame is right — the correct response to no reaction is not to quit but to hold the sprawl and trust the angle.
At open mat this week, separate the setup from the finish. Start already in north-south on a same-rank partner, arms uninvolved. Fifteen-minute round, one job: clear and pin the near arm — chest down, walk it away from the neck — then insert the choking arm and set the Gable grip, without yet finishing. Your partner's only task is to protect and free that near arm. You are training the precondition, not the strangle.
Add a second round in which you are allowed the finish, applied at a controlled pace, with one rule: no squeezing. Once the grip is set, your hands do not tighten. The only thing you are allowed to do is sprawl your hips back-and-down and drop the shoulder into the neck. If you catch yourself cranking with the arms, stop, reset, and fix the head-and-shoulder angle instead. Tap early and often for each other — this is a fast choke, and drilling it safely means respecting how quickly it closes.
Repeat weekly. The strangle that looks like nothing will start ending your rounds without a visible fight.
The north-south choke is the signature finish of a scoreless pin — a submission that only exists because someone chose to attack from a position the scoreboard ignores.
Every one of these is one reversed chest-to-chest connection away from the finish. The choke is what that connection is for.
