The guard is what makes BJJ different from every other martial art. You're on your back, and you're dangerous. In wrestling, being on your back means you're losing. In BJJ, it means you're hunting.
As our fundamentals instructor puts it: "The guard position is extremely important and the reason why is because the goal of Jiu-Jitsu is to fight on the ground and end up on top. But of course, life doesn't always go your way. Even when you're trained, given all the chaos and stuff in a fight, maybe you're fighting a guy who's bigger and stronger than you are." Understanding BJJ guard positions is understanding the foundation of jiu-jitsu. Every sweep, submission, and escape from bottom starts with a guard position. This guide breaks down the 5 guards you need to know, from the most basic to the most advanced, with the attacks and transitions from each.
Why the Guard Matters
Scott Sullivan teaches the guard with self-defense as the starting point: "The guard is the most important position in jiu-jitsu. If you can't fight off your back, you can't fight." In self-defense, you end up on your back more often than you end up on top. The guard makes that survivable and turns it into an advantage.
1. Closed Guard: Your Safe House
Closed guard means your legs are locked around your opponent's waist. They're trapped between your legs with limited mobility. This is the most controlling bottom position in BJJ and where beginners should live. As the instructor says: "The most important thing when you're in guard in a fight is protect your face. Don't get punched. I'm going to show you how to do that."
From closed guard, you control the pace. Your opponent can't stand up, pass, or create distance without first breaking your leg lock. The primary attacks: armbar, triangle choke, kimura, and hip bump sweep. Every attack in closed guard starts with breaking your opponent's posture. Pull their head to your chest. Once their posture is broken, everything opens up.
2. Open Guard: Distance and Dynamics
When your closed guard gets broken, or when you choose to play with more mobility, open guard takes over. Your legs aren't locked. Instead, you use hooks, frames, and grips to control distance and create attacks.
Open guard is where BJJ gets creative. Spider guard uses sleeve grips and feet on biceps. Lasso guard wraps your leg around their arm. De La Riva hooks the outside of their leg. Each variation has specific sweeps and submissions. The common thread: your feet and hips stay active. The moment you go flat and passive in open guard, you get passed.
3. Half Guard: The Comeback Position
Half guard happens when your opponent has passed one of your legs but you've trapped the other. For years, half guard was considered a "bad" position. Modern BJJ has turned it into one of the most powerful guards in the sport.
The key to half guard is the underhook. Get on your side (never stay flat on your back), thread your arm under their armpit, and fight for that underhook like your life depends on it. With the underhook, you can sweep, take the back, or stand up. Without it, you're getting flattened and passed. The underhook is the difference between half guard as a weapon and half guard as a waiting room for side control.
4. Butterfly Guard: The Sweep Machine
Butterfly guard means you're sitting up with both feet hooked inside your opponent's thighs. It's the most aggressive guard for sweeping because your hooks are already under their center of gravity.
The butterfly sweep is one of the highest-percentage sweeps in BJJ. Overhook one arm, underhook the other, and fall to the underhook side while elevating with your hook. Your opponent goes over you and you land in mount or top position. The beauty of butterfly guard is its simplicity. Two hooks, one grip, one direction. Even against larger opponents, the elevator hook creates enough lift to off-balance them.
5. Half Guard Passing Defense: Using the Guard to Recover
Guard positions aren't just offensive tools. They're recovery positions. When you're getting passed, half guard is often the last line of defense before side control.
The key: don't just hold the leg and pray. Use the lockdown (triangle your legs around their trapped leg) to control their movement while you work for the underhook. From the lockdown half guard, you can whip sweep (electric chair) or simply use the control to recover to a better guard position. Think of half guard as your "break glass in case of emergency" position. It buys you time and options when everything else has failed.
Building Your Guard Game
Start with closed guard. Master the posture break, the armbar, the triangle, and the hip bump sweep. Once you're comfortable there, develop half guard with the underhook. Then explore open guard and butterfly. Each guard feeds into the others. Closed guard gets broken and becomes open guard. Open guard gets half-passed and becomes half guard. Half guard gets recovered back to closed guard. The cycle is your bottom game.
