The Basic Butterfly Sweep is a fundamental technique from Half Butterfly guard that exploits opponent’s forward pressure and balance. Using a single butterfly hook underneath the opponent’s free-side thigh while the half-guard legs control the trapped leg, combined with an underhook and grip control plus hip movement, the practitioner elevates and off-balances the opponent to achieve a dominant top position. This sweep is highly effective against opponents who attempt to establish base on top of half butterfly or pressure forward without proper posture. The technique relies on timing, leverage, and the mechanical advantage created by the lone butterfly hook plus half-guard control rather than pure strength. When executed properly, the Basic Butterfly Sweep can transition smoothly into mount, side control, or back control depending on the opponent’s defensive reactions. This is considered an essential technique for all BJJ practitioners and forms the foundation for more advanced half-butterfly and butterfly guard sweeping systems.

Key Attacking Principles
What are the key principles for executing Basic Butterfly Sweep?
- Maintain active butterfly hooks with heels close to opponent’s hips for maximum elevation leverage
- Break opponent’s posture and control their upper body through grips before initiating sweep
- Use hip movement to create proper 45-degree angle and mechanical leverage before driving
- Time the sweep when opponent commits weight forward over your hooks
- Drive hooks upward and forward while pulling upper body grips to create unified rotational force
- Follow through with bodyweight to establish top position without disconnecting
- Maintain connection throughout the sweep to prevent escape and ensure consolidation
Prerequisites
What do you need before attempting Basic Butterfly Sweep?
- Half butterfly established with one butterfly hook under opponent’s free-side thigh and the half-guard legs controlling the trapped leg
- Secure underhook and grip control on opponent’s collar, sleeve, or overhooks
- Opponent’s weight committed forward or balanced neutrally over your hips
- Your hips mobile and turned onto your side underneath opponent’s center of gravity
- Proper distance maintained - not too close to compress, not too far to lose the hook
- Active hook engagement with the heel pulled toward opponent’s hip
Execution Steps
How do you execute Basic Butterfly Sweep step by step?
- Establish half butterfly position: Secure half butterfly with the half-guard legs trapping opponent’s near leg and a single butterfly hook inserted under their free-side thigh, heel pulled in toward their hip. Turn onto your side with active posture, controlling opponent’s upper body with an underhook plus collar and sleeve grips. Your hips should be mobile and ready to move.
- Secure upper body control: Establish strong grip control - typically collar and sleeve grips, double underhooks, or overhook/underhook combinations. Pull opponent’s upper body down and forward to break their posture and bring their weight over your hips. This control is critical for preventing them from posting and defending the sweep.
- Create angle with hip movement: Shift your hips at a 45-degree angle away from the side you intend to sweep toward. This angling creates better leverage for the butterfly hook and positions your body to follow through into top position. Your spine should be curved toward the sweeping direction.
- Drive butterfly hook upward: Explosively extend the butterfly hook on the sweeping side upward and forward, driving through your heel and lifting opponent’s leg off the mat. Simultaneously pull their upper body in the direction of the sweep using your grips. The hook creates elevation while the grips create rotation.
- Roll opponent over your body: Continue driving the butterfly hook while pulling their upper body across your centerline. Fall back slightly on the sweeping side, allowing opponent’s momentum to roll over you. Your opposite butterfly hook helps stabilize and can be used to further off-balance them if needed.
- Follow through to top position: As opponent rolls over, immediately follow their movement by coming up on your knees and establishing top position. Drive your chest forward and maintain grip control to prevent them from recovering guard. Depending on the angle and their defensive reactions, you can land in mount, side control, or take the back.
- Consolidate position: Once on top, quickly establish control by securing proper weight distribution, controlling their hips and shoulders, and preventing guard recovery. If in mount, secure your base. If in side control, establish crossface and hip control. Maintain pressure to prevent escape attempts.

Opponent Counters
How might your opponent counter Basic Butterfly Sweep?
- Opponent posts hand on mat to block sweep (Effectiveness: High) - Your Response: Switch to attacking the posted arm with kimura, drive into the free-side hook to re-load the sweep, or transition to single leg X-guard by diving under the posted arm → Leads to Half Butterfly
- Opponent sprawls hips back and creates distance (Effectiveness: High) - Your Response: Follow their movement by extending the hook leg forward, switch to deep half guard entry, or stand up and pursue with front headlock control → Leads to Half Butterfly
- Opponent steps over butterfly hook to establish headquarters position (Effectiveness: Medium) - Your Response: Immediately switch to single leg X-guard, attack the trapped leg, or transition to reverse De La Riva guard before they can pass → Leads to Half Butterfly
- Opponent maintains strong upright posture and prevents forward weight commitment (Effectiveness: Medium) - Your Response: Use elevator sweep variation by pulling them forward with collar grip, or transition to deep half guard with the trapped leg and arm drags → Leads to Half Butterfly
- Opponent counters by driving weight extremely heavy onto your chest (Effectiveness: Low) - Your Response: Use their forward pressure to enhance the sweep - their committed weight actually makes the basic butterfly sweep easier to execute with proper timing → Leads to Mount
Safety Considerations
What are the safety concerns for Basic Butterfly Sweep?
The basic butterfly sweep is generally a low-risk technique when practiced correctly. However, practitioners should be aware of several safety considerations. When drilling, ensure controlled execution to avoid slamming your partner, especially on hard surfaces. Begin with slow, cooperative repetitions to develop proper mechanics before adding speed and resistance. For the person being swept, learn to breakfall properly by slapping the mat with your arm to disperse impact energy. Avoid stiff-arming or posting with straight arms when defending the sweep, as this can lead to wrist, elbow, or shoulder injuries. When executing the sweep, maintain control of your partner’s upper body throughout to prevent uncontrolled falls. If you have knee issues, be cautious with the butterfly hook position as it requires some knee flexibility and can stress the joint if hooks are too shallow or if weight is dropped suddenly. Start with light resistance and gradually increase intensity as your body adapts to the positions and movements.
