The Butterfly Smash is a fundamental pressure passing technique designed to neutralize and collapse the butterfly guard structure. This pass exploits the inherent weakness of butterfly hooks when met with forward pressure and proper weight distribution. By driving your weight through specific points of control while systematically removing the bottom player’s frames and hooks, you create a pathway to dominant top positions.
The technique emphasizes pressure over speed, making it highly effective against technically proficient guard players who rely on maintaining distance and active hooks. Rather than attempting to move around the legs quickly, the butterfly smash works by making the guard itself structurally unsound through sustained chest-to-chest connection and progressive hip pressure. This forces the bottom player flat, removing the upright posture their hooks require to generate elevation.
Understanding the mechanics of hip pressure, shoulder positioning, and incremental advances makes this pass a cornerstone of any pressure-based passing system. It chains naturally with knee slice passes, body lock passes, and long step passes, providing a complete toolkit against butterfly guard. When the bottom player defends by transitioning to half guard, the passer is already in an advantageous position to continue passing with appropriate follow-up techniques.

Playing as Attacker
Key Principles
-
Forward pressure through the opponent’s center line to collapse butterfly structure and eliminate upright posture
-
Systematic removal of frames and hooks before attempting to pass around the legs
-
Weight distribution through shoulders and hips to pin lower body and prevent hook re-insertion
-
Incremental position improvement rather than explosive movements that create space
-
Control of opponent’s upper body through crossface or underhook to prevent re-guarding
-
Chest-to-chest connection maintained throughout to eliminate recovery space
-
Patience in maintaining pressure while opponent exhausts defensive options and energy
Execution Steps
-
Establish upper body control: Secure grips on opponent’s collar or control both sleeves. Drive your forehead into opponent’s chest…
-
Choose side and begin pressure: Select the side where opponent’s butterfly hook feels weaker or where you have better grip control. …
-
Drive knee to mat: On your chosen side, drive your knee to the mat beside opponent’s hip, pinning their bottom leg and …
-
Clear first butterfly hook: Use your knee pressure and forward drive to force opponent’s first butterfly hook to flatten or lose…
-
Secure crossface or underhook: As the first hook clears, immediately establish a crossface by driving your forearm across opponent’…
-
Step over second leg: With the first hook neutralized and upper body control established, step your far leg over opponent’…
-
Consolidate side control: Bring your stepping leg back to establish proper side control base with knee near opponent’s hip. Di…
Common Mistakes
-
Attempting to pass too quickly without establishing sufficient pressure
- Consequence: Opponent easily maintains hooks and can sweep or re-establish guard
- Correction: Take time to fully collapse the structure with pressure before attempting to move around the legs
-
Keeping hips too high during the smash
- Consequence: Opponent can use hooks effectively to elevate and sweep
- Correction: Drop hips toward the mat while maintaining chest pressure, create a low, heavy base
-
Neglecting to control opponent’s upper body before passing
- Consequence: Opponent sits up, re-establishes guard, or attacks submissions
- Correction: Always secure crossface or underhook before attempting to step over the second leg
Playing as Defender
Key Principles
-
Maintain upright seated posture at all costs - once flattened, the hooks lose all mechanical advantage for sweeping
-
Keep hooks active with constant upward elevator pressure rather than passive foot placement under the thighs
-
Deny chest-to-chest connection through frames on the shoulder and bicep before the passer closes distance
-
Fight grips aggressively to prevent the passer from establishing collar or sleeve control that enables the drive
-
Transition early to alternative guards when butterfly structure is compromised rather than fighting a losing battle
-
Use offensive threats like arm drags and sweep attempts to keep the passer defensive and prevent them from settling into their pressure game
Recognition Cues
-
Opponent drives forehead into your chest or sternum while keeping elbows tight to their body, indicating they are initiating the pressure sequence
-
Opponent begins stepping one knee toward the mat beside your hip, attempting to wedge between your hook and the mat to neutralize elevation
-
Opponent establishes heavy collar grip or wrist control and lowers their center of gravity while driving forward rather than attempting to stand or create distance
-
You feel your upright posture being compromised as opponent’s chest pressure forces your shoulders toward the mat and your hooks begin losing their upward angle
Defensive Options
-
Pump hooks explosively while maintaining upright posture and pulling opponent forward with collar or underhook grip to execute a butterfly sweep - When: Early in the engagement before the passer establishes chest pressure and before your posture is broken. Most effective when passer leans forward committing weight
-
Execute an arm drag on the passer’s lead arm to access their back, pulling their arm across your body while circling behind their shoulder line - When: When the passer reaches forward to establish collar or sleeve grips, creating the opportunity to redirect their arm. Most effective before they tighten elbows to body
-
Frame on the opponent’s shoulders and biceps, shrimp your hips away to create distance, then re-establish seated posture with active hooks - When: When the passer has begun driving pressure and your posture is being compromised but hooks are still active. This is the primary recovery mechanism when the smash is in progress
Position Integration
The Butterfly Smash integrates into a comprehensive pressure passing system as a fundamental response to butterfly guard. It connects seamlessly with other pressure-based passes like the double under pass, long step pass, body lock pass, and knee slice, forming a coherent passing chain. When opponents defend the butterfly smash by transitioning to half guard, you can immediately switch to appropriate half guard passing sequences such as the knee slice or crossface pass. The technique also serves as an entry point for back-takes when opponents turn away to defend, and for mount transitions when you achieve full crossface control past side control. Understanding this pass builds the foundational pressure mechanics needed for more advanced passing systems and develops the chest pressure sensitivity that transfers to all top-game positions.
