Deep Half Guard

Last updated: May 29, 2026

What is the deep half guard?

The deep half guard is a variation of the half guard, the position where a grappler on the bottom traps one of the top player’s legs. What separates the deep version is depth. Instead of staying on the side and fighting for an underhook, the bottom player burrows all the way under the opponent’s hips and pulls them up onto the chest. Wikipedia describes it as using half guard to get underneath the body of the opponent, a spot used mainly for sweeping because submission options are limited.

The point of getting that deep is leverage. Once the bottom grappler is under the opponent’s center of gravity, the person on top has little weight pressing down and almost nothing to attack. BJJ black belt Rob Biernacki, in a Grapplearts breakdown, calls deep half the closest range of the half guard, since the player sits directly beneath the opponent’s hips. From there, the bottom grappler can tip the opponent forward or roll them backward and come up on top.

The position sits at the offensive end of the half guard family. Grapplers once treated half guard as a losing spot, a last stop before the top player passed, until competitors turned it into an attacking platform. Lachlan Giles, an ADCC medalist who teaches the position, notes that deep half works well for players who are not flexible, since it relies on getting underneath an opponent rather than bending into awkward shapes.

How the position works

Two elements define the deep half guard. The bottom player gets underneath the opponent and hugs one of the opponent’s trapped legs tightly, then uses that connection to keep tipping them off balance. Lose the depth or lose the leg, and it stops being deep half.

Because the bottom grappler sits under the hips, the opponent’s weight falls past them instead of onto them. According to BJJ Fanatics, that is why the position works on much larger training partners, as a heavier person cannot flatten someone they cannot get their weight onto. The trade-off is that the bottom player has given up most of their own offense. Few submissions are available, so the game runs on sweeps, with the occasional kneebar on the trapped leg as a bonus.

The opponent on top has roughly three responses, as the Evolve MMA coaching staff lay out. They can try to pass by stepping over the head, attack the far arm with something like a kimura, or hunt for the neck. Each has a counter, and reading which one is coming is most of the work from underneath.

Deep half guard vs. classic half guard

Most people who look up deep half already know regular half guard, and the confusion is usually about what makes the deep version different. The short version is this. In classic half guard, the bottom player stays on their side and keeps the opponent off to one side. In deep half, they pull the opponent all the way on top and slide underneath. Evolve MMA puts the core distinction plainly, noting that deep half requires the bottom player to pull the opponent completely on top of them.

	Classic half guard	Deep half guard
Bottom player’s position	On the side, framing against the opponent	Underneath the opponent’s hips
Main grip	Underhook on the far side	Both arms wrapped around one trapped leg
Primary goal	Recover guard, take the back, or sweep	Off-balance the opponent and sweep
Submissions available	Several	Few
Weight on the bottom player	Moderate to heavy	Little

A quick note on related terms. Deep half is one of several half guard variations, alongside the knee shield (also called Z guard or 93 guard), the lockdown, the half butterfly, and others. They differ mainly in where the bottom player’s knees and frames sit relative to the opponent’s hips.

Where deep half guard connects to other positions

Deep half is rarely a final destination. Players enter it and leave it constantly, which is why coaches tend to treat it as a hub rather than a parking spot.

Common entries include the Z guard, which the half guard literature lists as a natural gateway into deep half, along with the De La Riva guard, the lasso guard, and a counter to an opponent’s knee cut pass. The idea is the same in each case. When space opens up under the opponent, the bottom player shoots an arm and the head through it and gets deep.

On the way out, deep half feeds into other attacking guards. Evolve MMA notes that when the opponent stands up to defend, the bottom player can switch to X guard or the 50/50 guard and keep hunting sweeps. Lucas Leite’s coyote half guard, profiled by BJJ Fanatics, blends deep half with the lockdown to borrow the strengths of both.

Common misconceptions

A few ideas about deep half guard come up often enough to be worth correcting.

One is that it is only for small grapplers. The position is popular with smaller competitors because it cancels out a size disadvantage, but its best-known players come in every size. Bernardo Faria, a five-time IBJJF world champion, built much of his game around half guard and deep half while competing as a heavyweight.

People also assume deep half is a beginner move because it looks simple from the outside. Most instructors put it in the advanced column. Evolve MMA points out that newer students often find the position cramped and uncomfortable, and the usual advice is to get comfortable with standard half guard before burrowing underneath.

Then there is the belief that it is a submission position. It mostly is not. The trapped leg occasionally opens a kneebar, but the value of deep half lies in reversing position, not finishing the fight.

Frequently Asked Questions

Is deep half guard good for beginners?

Most coaches treat it as an advanced position and suggest learning basic half guard first. Beginners can drill it, but it tends to feel cramped until they get used to being underneath an opponent.

Who invented the deep half guard?

Jeff Glover, a No-Gi World Champion and ADCC medalist, is widely credited as one of the position’s original innovators and popularisers. The broader half guard it grew out of was pioneered by Roberto “Gordo” Correia in the 1990s.

Does deep half guard work in MMA?

It is far more common in sport BJJ than in MMA. Sitting flat underneath an opponent exposes the bottom grappler to strikes, so it appears mostly in pure grappling and submission-only rulesets rather than in the cage.

What is the main goal of deep half guard?

To get under the opponent’s center of gravity, break their balance, and sweep them into a top position such as side control or mount.

Can you submit someone from deep half guard?

Options are limited. A kneebar on the trapped leg is the most common one, but the position is built for sweeping rather than finishing.
