The Butterfly Half Guard Sweep is a fundamental sweep technique executed from butterfly half guard bottom, leveraging the unique mechanical advantages of this hybrid position. The sweep utilizes the butterfly hook inserted under the opponent’s free leg to generate upward elevation force while the half guard trap on the other leg prevents the opponent from posting or stepping to base out. This combination of elevation and entanglement creates a powerful sweeping platform that disrupts the top player’s balance along a diagonal line, forcing them to topple over the trapped leg.
Strategically, this sweep functions as both a primary attack and a setup tool within the butterfly half guard system. When the opponent defends by posting a hand or shifting weight, they create openings for complementary techniques like the 100% sweep, old school sweep, or back take entries. The sweep is most effective when the opponent’s weight is centered or slightly forward, as their momentum can be redirected through the elevation arc. Against opponents who post back heavily to defend, the sweep becomes less viable but opens transitions to deep half guard or X-guard entries.
The technical execution demands precise coordination between the butterfly hook drive, underhook pull, and hip angle adjustment. The sweep succeeds through timing and leverage rather than strength, making it accessible to practitioners of all sizes when executed with proper mechanics. The half guard trap serves as the critical differentiator from a standard butterfly sweep, providing additional control that prevents the common counter of simply stepping the free leg back to recover base.

Playing as Attacker
Key Principles
-
Establish deep underhook on butterfly side before attempting sweep to ensure upper body pulling power for the toppling motion
-
Create hip angle approximately 45 degrees to opponent’s centerline to optimize the diagonal sweep trajectory over the trapped leg
-
Load opponent’s weight over the butterfly hook before driving to maximize elevation leverage and off-balancing effect
-
Coordinate butterfly hook drive with underhook pull as a single unified movement, never as sequential actions
-
Maintain half guard trap throughout sweep execution to prevent opponent from posting their trapped leg to base
-
Time the sweep when opponent’s weight shifts forward or they commit to passing, redirecting their momentum into the sweep arc
Execution Steps
-
Confirm grip configuration and hook placement: Verify underhook is deep on butterfly side with your hand controlling opponent’s lat or reaching the…
-
Adjust hip angle to create sweep trajectory: Shift your hips approximately 45 degrees relative to the opponent’s centerline, angling toward the b…
-
Load opponent’s weight over butterfly hook: Use your underhook to pull opponent’s upper body forward and toward the butterfly hook side, stackin…
-
Drive butterfly hook upward explosively: Extend your hip and knee on the butterfly hook side in an explosive upward and outward motion, lifti…
-
Pull underhook toward opposite hip simultaneously: As the butterfly hook drives upward, pull your underhook arm forcefully toward your opposite hip in …
-
Follow opponent over and establish top position: As the opponent falls to the side, follow their momentum by rotating your body over them. Release th…
-
Consolidate side control and secure grips: Once on top, immediately establish crossface control and hip pressure to prevent guard recovery. Rel…
Common Mistakes
-
Attempting the sweep without establishing a deep underhook first
- Consequence: Sweep lacks the upper body pulling power necessary to topple opponent, resulting in ineffective elevation that opponent easily resists and potentially counters
- Correction: Always fight for and establish a deep underhook on the butterfly side before committing to the sweep attempt
-
Driving butterfly hook straight up instead of at a diagonal angle matching hip positioning
- Consequence: Opponent can base out easily because force is directed upward rather than along the optimal sweep trajectory over the trapped leg
- Correction: Adjust hip angle first to create the 45-degree position, then drive the hook along that diagonal to direct opponent over the trapped leg
-
Sequencing hook drive and underhook pull instead of executing them simultaneously
- Consequence: Opponent has time to react and base out between the two movements, significantly reducing sweep percentage
- Correction: Practice coordinating the hook drive and underhook pull as one unified explosive movement, initiating both at the exact same moment
Playing as Defender
Key Principles
-
Deny the underhook on the butterfly side through active hand fighting and whizzer control to remove upper body pulling power
-
Keep hips low and heavy to prevent butterfly hook elevation from generating meaningful upward force against your base
-
Recognize sweep timing by monitoring opponent’s hip angle adjustments and increased butterfly hook pressure
-
Maintain wide base with free leg posted for stability against the diagonal sweep trajectory
-
Apply crossface pressure to prevent opponent from achieving the seated posture necessary for sweep leverage
-
When sweep is initiated, sprawl hips back immediately rather than trying to resist the elevation force directly
Recognition Cues
-
Opponent adjusts hip angle to approximately 45 degrees relative to your centerline, creating the diagonal sweep trajectory
-
Opponent fights aggressively for an underhook on the butterfly side, attempting to thread their arm deep under your armpit
-
Butterfly hook pressure increases significantly with active upward driving through opponent’s foot beneath your thigh
-
Opponent shifts from passive guard retention to active pulling with their upper body grips, loading your weight forward over the hook
-
Opponent’s posture becomes more upright or seated with their shoulders rising off the mat to generate sweeping leverage
Defensive Options
-
Sprawl hips back and apply heavy crossface to flatten opponent’s posture - When: When you feel the butterfly hook begin to elevate or opponent establishes underhook on butterfly side
-
Whizzer opponent’s underhook arm and drive shoulder pressure to strip their grip - When: Immediately when opponent establishes underhook on butterfly side before they can coordinate the full sweep
-
Post far hand wide on the mat and widen base against the sweep direction - When: When sweep is already in motion and you need immediate emergency base to prevent being toppled
Position Integration
The Butterfly Half Guard Sweep occupies a central role within the butterfly half guard offensive system, serving as one of several sweeping options that create an interconnected threat matrix from this hybrid position. It complements the 100% sweep and old school sweep by attacking along a different vector, forcing the top player to defend multiple angles simultaneously. When this sweep is stuffed, it naturally chains into deep half guard entries, dogfight scrambles, or back take opportunities depending on the opponent’s defensive reaction, making it a low-risk high-reward technique that maintains offensive pressure regardless of outcome. The sweep also connects the butterfly half guard system to the broader top game, as successful execution deposits the sweeper directly into side control where submissions and further positional advancement become available.
