The Quarter Guard is a common transitional position in BJJ and grappling that occurs when a guard player's half guard has been partially passed β the passer has cleared one leg but the guard player retains a foot or ankle hook on the passer's lower leg. Understanding quarter guard is essential for both the bottom and top player: the passer must complete the pass cleanly, while the guard player must recover guard, create a sweep, or attack a leg lock before being fully passed.
Quarter guard occurs when you are playing half guard and your opponent has partially passed β they have cleared one of your legs and their hip or chest is beginning to flatten you out. You retain a single hook (foot or ankle) on their far leg, creating a "quarter" of the original guard entanglement.
It is inherently a precarious position for the bottom player. The top player has significant upper body and hip control. The bottom player must act quickly: either recover to half guard, attempt a sweep, or transition to a leg entanglement.
Quarter guard appears constantly in competitive grappling β most half guard passes go through quarter guard before completion. Mastering the transitions from this position is a high-leverage skill.
In quarter guard, the bottom player typically has one ankle or foot hook around the passer's far knee or ankle. The passer is angled across the bottom player's body β their hip is past the bottom player's near hip, but the hook prevents flat completion of the pass.
The bottom player's near-side arm is usually trapped or pressured. Framing on the passer's hip or thigh with the far-side arm is essential to create space. The bottom player's head should be turned away from the passer to prevent the passer from using head control to flatten them.
The primary goal from quarter guard is to re-establish half guard. Use a hip escape (shrimp) toward the trapped hook side. As you create space, re-insert the top leg back into a full half guard hook. Once both legs are engaged, you've recovered guard successfully.
If you can get your hook deep (into the crook of their knee), look to come up on your near-side elbow to the dogfight position β this is the gateway to the electric chair sweep, back-take, or half guard sweeps.
From quarter guard, your hook leg is already entangled with the passer's far leg. If the passer's leg alignment is favorable, you can transition directly into a heel hook entry by rotating your hips under them and capturing their knee in an outside ashi garami configuration. This is legal in advanced adult divisions (no-gi) and increasingly used in competition.
When the passer is heavy on top and pushing forward, use their pressure against them: curl your top knee in, use your far-side arm to post on the mat behind you, and roll backward to take top position. This works best when the passer is base-heavy and not protecting their far side.
Drive your hip into the bottom player's hip to flatten them, then step your trapped leg free by lifting the knee and circling it over the hook. Secure side control immediately after clearing the hook.
If already in a knee slice position, continue driving the knee across their thigh to break the hook. Use your gripping arm to push their knee down while driving your hip to the mat.
Advanced passers use a cartwheel or leg drag over the bottom player's legs to clear the quarter guard hook quickly and arrive in side control on the other side before the guard player can react.
Quarter guard is a natural entry point for leg locks in no-gi grappling. The bottom player's hook already puts them in early ashi garami alignment. From quarter guard, transitions to:
In gi competition below brown belt, heel hooks are not available, so quarter guard leg entries should focus on the back take or guard recovery instead.
No. Half guard means both your legs are entangling one of your opponent's legs. Quarter guard means you only have a single foot or ankle hook on their far leg β the pass is partially complete. Quarter guard is generally a worse position for the bottom player than half guard.
In no-gi competition (advanced divisions where heel hooks are legal), yes β quarter guard leg lock entries are high-percentage because you're already in early ashi garami alignment. In gi or beginner no-gi divisions, focus on re-guarding or the dogfight sweep instead.

To prevent a stack pass, focus on maintaining a strong frame with your forearm against their hip or shoulder, and use your free leg to hook their leg or push off their body. Keeping your hips active and away from their pressure is also crucial.
Common attacks from Quarter Guard include sweeps like the 'knee-slide sweep' or 'hook sweep', and submissions such as the 'armbar' or 'kimura' when your opponent overcommits. You can also transition to other guards like Half Guard or Butterfly Guard.
