BJJ Positions Explained: The Hierarchy That Runs Everything

Jiu-jitsu positions form a hierarchy from back control down to being mounted. Knowing where a position sits, what it threatens and what it offers is the map every roll runs on.

Beginners experience rolling as chaos because they cannot name what is happening. Once you can name it, a roll turns into a sequence of positions, each with a small set of options, and the chaos mostly disappears.

Here is the map, in the order of value the sport actually assigns.

The hierarchy, top to bottom

PositionWho is winningMain threat
Back controlThe person behind, decisivelyRear naked choke and collar chokes
MountThe person on topChokes, armbars, ground and pound in an MMA context
Knee on bellyThe person on topPressure, transitions to mount, armbars, chokes
Side controlThe person on topPressure, kimura, americana, transitions to mount
Half guardContested, depends on grips and underhooksA sweep or a pass, sometimes attacks from both
Closed guardThe person on the bottom, mildlySweeps, armbars, triangles, chokes
Open guardContested, depends on gripsSweeps and entries from below, passes from above
TurtleThe person on topBack takes, front headlocks

Two things follow from the table, and they are the reason it is worth memorising.

First, the top of the hierarchy is not "on top". Back control beats mount, and both beat side control. Position value is about control and attack availability, not altitude.

Second, guard is the only position where the person underneath is not losing. That is the single strangest thing about jiu-jitsu to a newcomer, and it is the whole reason the sport looks the way it does.

The positions, defined

Back control. You are behind your opponent with your chest to their back, usually with both hooks (your feet inside their thighs) or a body triangle, plus a seatbelt grip. It is the strongest position in the sport because they cannot see you, cannot easily defend the neck, and have almost nothing available in return.

Mount. You sit on their torso, knees on the mat. Low mount, with your hips over theirs, is where escapes exist. High mount, with your knees in their armpits, is where submissions live. Escaping mount depends almost entirely on stopping that climb.

Knee on belly. One knee across their stomach, one foot posted, weight controlled. Uncomfortable to be under, mobile to hold, and a common bridge between side control and mount.

Side control. Chest to chest across their body, perpendicular, no legs involved. It is the most common position for beginners to be stuck under, and getting out of it is the first real skill most people build.

Half guard. You have one of their legs trapped between yours. Contested territory: the person on the bottom is fighting for an underhook and a sweep, the person on top is fighting to free the leg and take side control.

Closed guard. You are on the bottom with your legs wrapped around their waist, ankles crossed behind them. You control their posture and distance, and you can attack. The person on top has to open the guard before they can do anything.

Open guard. Any bottom position where your legs are not locked: de la Riva, spider, butterfly, half butterfly, and a long list of others. Distance management is everything, and it is where most passing battles are decided, which is why guard retention is its own subject.

Turtle. On your knees and elbows, protecting your front. Defensive, and dangerous, because it is one step from giving up your back.

What the hierarchy is actually for

The reason to learn the order is that it tells you what to do next, without thinking, in a scramble.

If you are in a worse position, your job is to get to a neutral one, not to attack. If you are in a neutral position, your job is to improve it. If you are in a dominant position, your job is to hold it until an attack is free, not to gamble the position on a submission attempt.

That single principle, position before submission, is the most repeated advice in the sport, and the hierarchy is what makes it actionable rather than a slogan.

Each position is a short list of decisions

A position is not a place, it is a menu. Side control bottom offers you roughly three real things: frame and shrimp toward guard, underhook and come up, or wait and defend while they set something up. Closed guard offers you posture control, a sweep, or an attack. Turtle offers you standing up, rolling, or shelling.

Two or three real options, a trigger for each, a consequence for choosing wrong. That is what a position is, and it is why treating jiu-jitsu as a decision tree makes it learnable, while treating it as a technique library makes it endless.

Which is also the difference in how two people experience the same roll. One is in a scramble and reacting. The other is in a known position, running a known menu, and choosing.

How to learn the map fast

Spend two weeks naming positions instead of trying to win from them. During rolls, and immediately after, say to yourself what position you were in and what it was threatening. That is all.

It sounds trivial and it is the fastest single upgrade available to a beginner, because you cannot choose an option from a position you have not identified. Everything after that, the escapes, the sweeps, the attacks, is built on the map being there.

BJJ position questions

What is the best position in BJJ?

Back control, with both hooks or a body triangle and a seatbelt grip. It gives the strongest attacks and offers almost nothing in return, which is why it sits at the top of every version of the hierarchy.

Is guard a good position or a bad one?

Neutral to good, depending on the guard and the grips. It is the only bottom position that is not losing: you can attack, sweep and control distance from it. The person on top must solve the guard before they can advance.

What does "position before submission" mean?

Establish a controlling position first, then attack from it, rather than chasing a submission from an unstable place. Attempting a submission usually costs some control, so the principle says spend that control only when you already have plenty.

What is the difference between half guard and closed guard?

In closed guard your legs are locked around their waist and they are inside your guard entirely. In half guard you have trapped only one of their legs, which makes it a contested position where either person can improve.

How many BJJ positions do I need to know?

The eight in the table cover almost everything you will meet in your first two years. What matters is not adding more, but knowing what each one threatens and what your two or three options are from it.

Know where you are. Know what it offers.
