As the attacker executing this transition, your objective is to systematically dismantle the bottom player’s butterfly guard by clearing one hook while maintaining upper body control. This converts the position from a dangerous, sweep-heavy guard into an asymmetric configuration where your passing options multiply. The key insight is that you are not trying to pass the guard in one motion. You are removing one layer of the bottom player’s defense, creating a position where subsequent passing techniques have dramatically higher success rates. Patience and pressure discipline are more important than speed. Establish your controls, identify the weaker hook, and execute the clearing sequence with deliberate precision.

Key Attacking Principles
What are the key principles for executing Butterfly Guard to Half Butterfly?
- Establish upper body control before attempting to clear any hook, as uncontrolled clearing invites sweeps
- Target the weaker hook first, identified by which side the opponent’s grips and weight favor less
- Use bodyweight and skeletal alignment rather than muscular effort to collapse the hook’s leverage
- Maintain constant forward pressure throughout the clearing sequence to prevent hook re-insertion
- Keep your base wide laterally to resist elevation attempts during the transition window
- Control the opponent’s hips and prevent them from turning into you as you clear the hook
- Consolidate half butterfly top immediately after clearing, do not rush into the next pass
Prerequisites
What do you need before attempting Butterfly Guard to Half Butterfly?
- Establish at least one dominant grip: crossface, collar grip, or underhook on the clearing side
- Achieve combat base or low kneeling posture with hips below opponent’s hook line
- Identify which hook is less supported by opponent’s upper body grips and weight distribution
- Create slight forward pressure to load the opponent’s hooks and feel which one bears less resistance
- Ensure your posture is not broken and your head is not pulled below opponent’s shoulder level
Execution Steps
How do you execute Butterfly Guard to Half Butterfly step by step?
- Establish upper body control: Secure a crossface or collar grip on the side where you intend to clear the hook. Your other hand controls the opponent’s far sleeve, lapel, or wrist. This upper body control prevents the opponent from turning into you and generating sweep angles during the clearing sequence. Without this control, any hook clearing attempt exposes you to immediate sweeps.
- Load weight onto the clearing side: Shift your center of gravity toward the side where you will clear the hook. Drive your chest forward and slightly toward that side, increasing the downward pressure on the target hook. This weight shift reduces the hook’s ability to generate upward lifting force and compresses the space the hook occupies. Your hip on the clearing side drops toward the mat.
- Drive knee to mat inside the hook: Push your knee on the clearing side downward toward the mat, driving it between the opponent’s legs and past their hook foot. The knee travels in a forward-and-down trajectory that collapses the space under your thigh where the hook sits. Use your shin and knee to pin the opponent’s foot or ankle to the mat, preventing immediate re-insertion of the hook.
- Swim the leg past the hook: Once the knee has driven past the hook’s engagement point, slide your entire leg through so that the opponent’s foot is now behind your thigh rather than under it. Maintain forward pressure throughout this movement to prevent the opponent from scooting their hips back and re-engaging the hook. Your leg should end up on the outside of the opponent’s former hook leg.
- Secure half guard passing position: With one hook cleared, immediately establish half butterfly top control. Drive your chest onto the opponent’s upper body, keeping your cleared-side hip heavy on the mat. Your other leg remains in the opponent’s remaining half guard or butterfly hook. Maintain the crossface or collar grip and adjust your weight distribution to neutralize the remaining hook’s lifting power.
- Consolidate and prevent recovery: Block the opponent’s primary recovery by controlling their far hip with your free hand and maintaining heavy shoulder pressure through the crossface. Prevent the opponent from re-inserting the cleared hook by keeping your knee tight against their inner thigh on the cleared side. Settle your weight and establish your base before initiating any subsequent passing sequence. This consolidation phase is critical and should not be rushed.
- Neutralize remaining hook threat: Address the opponent’s remaining butterfly hook by adjusting your hip angle so the hook cannot generate effective lift. Drive your hip on that side low and forward toward the mat, reducing the hook’s leverage. If the opponent attempts to elevate with the remaining hook, widen your base on the cleared side and increase chest pressure. This sets up your next passing sequence from a stable, advantageous position.

Opponent Counters
How might your opponent counter Butterfly Guard to Half Butterfly?
- Opponent elevates with both hooks as you begin weight shift (Effectiveness: High) - Your Response: Immediately post both hands wide and sprawl hips back to kill the elevation. Reset upper body control before reattempting the clear. Do not fight the sweep mid-elevation. → Leads to Mount
- Opponent re-inserts hook immediately after clearing by scooting hips (Effectiveness: Medium) - Your Response: Maintain constant forward pressure and pin their ankle or foot with your shin as you clear. If they re-insert, immediately re-drive the knee down rather than accepting the recovery. → Leads to Butterfly Guard
- Opponent transitions to deep half guard during weight shift (Effectiveness: Medium) - Your Response: If you feel them diving under, immediately sprawl hips back and drive crossface pressure to flatten them before they complete the deep half entry. Maintain head position above their shoulder line. → Leads to Half Guard
- Opponent arm drags during the clearing sequence (Effectiveness: High) - Your Response: Keep your elbows tight and maintain inside position with your clearing-side arm. If the arm drag connects, circle toward their back to avoid giving up back control and reset to combat base. → Leads to Mount
Safety Considerations
What are the safety concerns for Butterfly Guard to Half Butterfly?
This transition involves significant pressure application through the chest and shoulders onto the bottom player’s upper body. The top player should apply weight gradually rather than dropping suddenly, especially during drilling. During the knee drive phase, be mindful of the bottom player’s knee and ankle on the clearing side, as aggressive driving can compress joints uncomfortably. Both partners should communicate if pressure becomes excessive on the ribcage or neck area. When drilling repetitions, alternate sides to prevent overuse strain on one shoulder from repeated crossface applications.
