Half Butterfly Bottom

Jan 23, 20268 min read

Half Butterfly Bottom is a dynamic hybrid guard position that combines elements of half guard and butterfly guard. The bottom practitioner controls one of the opponent’s legs between their own legs (half guard component) while maintaining a butterfly hook on the free leg side. This position offers excellent sweeping opportunities and creates offensive dilemmas for the top player who must defend both the half guard escape and butterfly hook threats simultaneously.

The position is particularly effective in no-gi grappling and modern competitive BJJ, where practitioners use the butterfly hook to elevate and off-balance opponents while the half guard component prevents easy passing. The unique structure allows for multiple sweep variations, back-take opportunities, and transitions to other guard positions. Unlike traditional half guard which can be more defensive, Half Butterfly Bottom maintains constant attacking pressure through the butterfly hook’s lifting power combined with half guard control.

This position represents an evolution in half guard theory, popularized by practitioners like Marcelo Garcia and Lucas Leite, who recognized that adding the butterfly hook creates additional vectors of control and sweep mechanics that pure half guard lacks. The position excels in creating scrambles and forcing opponents into defensive postures, making it ideal for practitioners who favor dynamic, movement-based guard play.

Position Definition

  • Bottom player has one leg of opponent trapped between their legs (half guard control) while maintaining control of that trapped leg with both legs wrapped around it, preventing opponent from fully extracting the leg
  • Bottom player’s free leg maintains a butterfly hook positioned under opponent’s free-side thigh with foot placed on mat, creating elevation and off-balancing potential through hip lifting mechanics
  • Bottom player is on their side or partially on their back with shoulders turned toward opponent, maintaining active frames on opponent’s upper body with at least one underhook or overhook grip
  • Opponent is in a top position with one leg trapped in half guard while their free leg is threatened by the butterfly hook, forcing them to manage pressure distribution between defending the sweep and attempting to pass

Prerequisites

  • Opponent’s leg successfully trapped between bottom player’s legs in half guard configuration
  • Sufficient space created to insert butterfly hook on free-leg side
  • Bottom player maintains active hip mobility and can turn toward opponent
  • At least one upper body connection established (underhook, overhook, or collar grip)
  • Bottom player’s hips remain mobile and not flattened completely to mat

Key Defensive Principles

  • Maintain constant lifting pressure through butterfly hook to prevent opponent from settling their weight and establishing stable passing pressure
  • Use half guard leg control to prevent opponent from extracting trapped leg while simultaneously threatening sweeps with butterfly hook
  • Create angles by turning body toward opponent’s free side, using butterfly hook and upper body grips to off-balance opponent diagonally
  • Keep active frames and grips on upper body to prevent opponent from flattening you to back and controlling posture
  • Coordinate hip movement with butterfly hook elevation to create sweeping momentum rather than using arm strength alone
  • Maintain awareness of both sweep opportunities to trapped leg side and transitions to other guards if opponent defends
  • Use constant threatening motion to prevent opponent from consolidating passing pressure or establishing crossface control

Decision Making from This Position

If opponent is upright with high posture and not applying heavy pressure:

Else if opponent drives forward with heavy chest pressure attempting to flatten you:

Else if opponent attempts to extract trapped leg and establish passing pressure:

Else if opponent’s weight shifts to free-leg side defending butterfly hook:

Common Defensive Mistakes

1. Allowing butterfly hook to become passive without active lifting pressure

  • ❌ Consequence: Opponent can settle their weight and establish stable passing pressure, neutralizing sweep threats
  • ✅ Correction: Maintain constant upward pressure through butterfly hook, actively lifting and off-balancing opponent even when not executing sweep

2. Letting opponent flatten you completely to your back

  • ❌ Consequence: Loses hip mobility needed for sweeps and allows opponent to establish dominant crossface control
  • ✅ Correction: Stay on your side with shoulders turned toward opponent, using frames and grips to prevent being flattened while maintaining hip escape mobility

3. Losing half guard control while focusing on butterfly hook

  • ❌ Consequence: Opponent extracts trapped leg and easily passes to side control or mount
  • ✅ Correction: Coordinate both legs together - half guard legs squeeze trapped leg while butterfly hook lifts, creating dual threats opponent must address simultaneously

4. Using only arm strength to execute sweeps without hip elevation

  • ❌ Consequence: Sweeps are weak and easily defended, causing arm fatigue and failed sweep attempts
  • ✅ Correction: Drive sweeps primarily from hip extension and butterfly hook elevation, using grips only to guide opponent’s fall and control upper body

5. Maintaining static position without threatening constant movement

  • ❌ Consequence: Gives opponent time to establish grips, settle weight, and methodically work passing sequences
  • ✅ Correction: Create constant motion through hip movement, angle changes, and sweep attempts to keep opponent defensive and prevent them from establishing rhythm

6. Allowing opponent to achieve underhook on half guard side

  • ❌ Consequence: Opponent can drive shoulder pressure, flatten you, and control hip movement for easier passing
  • ✅ Correction: Fight for underhook on trapped leg side or establish strong frames to prevent opponent’s underhook from controlling your upper body

Training Drills for Defense

Butterfly Hook Elevation Drill

Partner in top half butterfly. Practice lifting and off-balancing opponent using only butterfly hook hip extension while maintaining half guard control. Focus on coordinating hip lift with angle creation.

Duration: 5 minutes per side

Sweep Transition Flow

Start in half butterfly bottom. Partner gives 50% resistance. Flow between different sweep options (butterfly sweep, old school, hook sweep) based on partner’s weight distribution. Emphasis on reading opponent’s pressure and selecting appropriate sweep.

Duration: 3 minutes per round

Half Butterfly Retention Sparring

Bottom player maintains half butterfly position while top player attempts to pass. Bottom player wins by executing successful sweep or maintaining position for 2 minutes. Top player wins by passing. Resets on successful defense or sweep. Develops retention and timing under pressure.

Duration: 5 minutes per round

Guard Recovery to Half Butterfly

Start with partner achieving initial passing pressure. Practice recovering half butterfly position using hip escapes, frames, and butterfly hook insertion. Simulates realistic guard recovery scenarios.

Duration: 10 reps per side
