Half Guard No-Gi: 7 Essential Sweeps & Attacks
Half guard used to be where you ended up when your guard got passed. In modern no-gi it is where matches are won. Watch any ADCC bracket and you will see world-class grapplers deliberately sitting in bottom half guard, hunting an underhook, and coming up to sweep bigger, stronger wrestlers. The half guard no-gi game rewards timing and framing over raw grip strength, which is exactly why it travels so well when the gi comes off. This guide breaks down the position and the seven attacks that actually finish against resisting partners.
Why Half Guard No-Gi Is a Different Animal Than the Gi
Strip the jacket away and two things change. There are no lapels to grip and no sleeves to control, so the whole position shifts toward the underhook and inside frames. That sounds like a downgrade, but it is the opposite. Without grips to slow you down, the bottom player can move faster and the sweeps come quicker. The trade-off is that a sweaty, slippery opponent is harder to hold, so control has to come from skeleton and positioning rather than fabric.
The other big shift is the wrestler problem. No-gi draws in athletes with heavy top pressure and no interest in playing your guard. Half guard is the answer, because it lets a smaller grappler get under a driving opponent and use their forward pressure against them. That is the whole appeal: the harder they push, the better your sweep works.
The One Thing That Matters Most: The Underhook
If you take nothing else from this article, take this. Nearly every high-level bottom half guard system is built around getting an underhook on the far side and getting to your hip. Flat on your back, half guard is a losing position. On your side with an underhook, it becomes an offensive launch pad.
Dig the underhook deep enough to reach the far lat, keep your head on the same side as the underhook, and post your free hand to stop yourself from being flattened. From here you are threatening to come up. The moment your opponent reacts to that threat, one of the sweeps below opens up. Lachlan Giles, who built a ten-hour instructional entirely around this position, calls the underhook sweep the main thing to know from half guard for a reason.
7 Essential Sweeps and Attacks From No-Gi Half Guard
These are ordered roughly from foundational to advanced. Drill the first two until they are automatic before you chase the flashier stuff.
1. The Old-School Underhook Sweep
The bread and butter. From your underhook, come up to your knees and reach the underhook arm around to grab your opponent’s far foot, not the ankle. Grip their near knee with your other hand, get on your toes, and circle hard toward the trapped leg. Done right you land in tight side control. This is the sweep everything else feeds off, so build it first.
2. Knee Shield to Butterfly Entry
When your opponent stays back and refuses to give you the underhook, insert a knee shield: your top knee frames across their hip, your bottom leg stays as a hook. The knee shield buys space and stops them from stapling you flat. From here you can shoot a butterfly hook under their leg and elevate, which links directly into the sweeps from no-gi butterfly guard.
3. The Shaolin Sweep
Named for Vitor “Shaolin” Ribeiro, this one uses a z-guard knee shield to extend your hips and bait the opponent into pressuring forward. As they drive in to kill your knee shield, you redirect that pressure, roll them over your head, and come up in top half guard or straight into a leg entry. It looks fancy, but it is really just borrowing your opponent’s momentum.
4. The Electric Chair (Lockdown)
Eddie Bravo’s lockdown is a 10th Planet staple and it is pure no-gi. You lace your legs to trap their leg, then use a double underhook or a whizzer read to hoist their trapped leg up and expose the electric chair. Even when the finish is not there, the lockdown ties up powerful opponents and buys you time to work.
5. The Dogfight Sweep
When you come up on the underhook and your opponent bases out to stop the sweep, you meet them in the dogfight, a knee-to-knee scramble position. From there you can run the pummel, take the back, or drive through to a reverse sweep. The dogfight is where most half guard exchanges are actually decided, so get comfortable living there.
6. The Back Take Off the Whizzer
Good opponents answer your underhook with a whizzer, an overhook that stuffs your shoulder. Instead of fighting it, use it. When they commit hard to the whizzer they overexpose their back, and you can duck under, take the back, and start hunting the rear naked choke. Half guard and no-gi back control are two ends of the same exchange.
7. The Kimura
The half guard kimura is the trap that keeps opponents honest. As they post a hand to stop your sweep, that arm is exposed. Snatch the kimura grip, and now you have a submission, a sweep, and a back take all off the same lock. Even if they defend the finish, the threat forces them to give up the underhook you wanted in the first place.

Common Mistakes That Get Your Half Guard Passed
The fastest way to lose the position is to lie flat. The second your shoulders hit the mat, your underhook dies and the top player walks into a no-gi knee cut pass. Stay on your side, always. The next mistake is going too high on the underhook and letting your opponent flatten your posture; keep the underhook deep and your elbow tight. Finally, do not stall in the dogfight waiting for a perfect moment. Hesitation there hands the initiative to the stronger athlete, and against a good wrestler that window closes fast.
One more gear note, since it matters more in no-gi than people admit: sweat makes everything slip. A rashguard that rides up or bunches under the arm kills your underhook connection at the worst possible moment. A snug top is not vanity here, it is a functional part of holding the position.
Building a Half Guard Game That Holds Up in Competition
Under the lights of a submission-only match, the grapplers who trust half guard are the ones who drilled the underhook until it was reflex. They are not thinking about which of the seven attacks to hit. They feel the reaction and the sweep happens. That is the goal: turn the position into a decision tree your body runs on its own.
Start narrow. Pick the underhook sweep and the knee shield entry, and drill only those for a month of rounds. Add the dogfight back take once the first two are landing. The half guard players who try to learn all seven attacks at once end up with none of them. If you also want to expand your bottom game beyond half guard, the sweeps from no-gi X-guard pair naturally with everything here, since half guard so often feeds directly into it.
Half Guard No-Gi FAQ
Is half guard good for no-gi?
Yes, and arguably it is better in no-gi than in the gi. Without lapel and sleeve grips to slow the action down, half guard becomes a fast, sweep-heavy position. It is the go-to answer for a smaller grappler facing a heavy top-pressure wrestler, because it lets you get underneath the drive and turn their forward pressure into your sweep.
What is the best sweep from no-gi half guard?
The underhook sweep, sometimes called the old-school sweep, is the highest-percentage option and the one to master first. You dig a deep underhook, come to your knees, grab the far foot, and circle into side control. Almost every other half guard attack builds off the reactions this sweep forces.
Why do I keep getting flattened in half guard?
You are staying on your back instead of your side. Half guard only works when you are turned onto your hip with an active underhook or knee shield. Frame, get to your side immediately, and never let your shoulders settle flat on the mat.
What is the knee shield in half guard?
The knee shield is a frame where your top knee crosses in front of your opponent’s hip or chest, creating distance and stopping them from pressuring into you. It is a defensive anchor that also opens up the Shaolin sweep and the entry into butterfly guard.
