As the attacker, you are the bottom player in half butterfly guard working to elevate to the dogfight position. Your primary tools are the deep underhook and the butterfly hook, which must work in concert to generate the upward and forward momentum needed to rise to your knees. The transition demands precise timing—rushing without proper grips results in being flattened, while waiting too long allows the top player to consolidate pressure. Success depends on coordinating the butterfly hook elevation with the underhook drive while maintaining half guard leg control throughout the rise. Once you reach dogfight, you have immediate access to sweeps, back takes, and further transitions that make this one of the highest-value positional improvements from bottom half guard.

Key Attacking Principles

What are the key principles for executing Half Butterfly to Dogfight?

  • Establish a deep underhook before attempting any elevation—the depth of the underhook determines your control throughout the entire transition
  • Coordinate butterfly hook elevation with underhook forward drive to create combined upward-and-diagonal force that the top player cannot resist from a single angle
  • Maintain half guard leg squeeze throughout the rise to prevent the top player from extracting their trapped leg and passing during the transition
  • Drive your head into the opponent’s chest or shoulder as you come up—head position determines who controls the dogfight configuration
  • Time the elevation to coincide with the opponent’s weight shift, passing attempt, or grip adjustment when their base is momentarily compromised
  • Commit fully to the transition once initiated—half-hearted attempts leave you in a worse position than where you started

Prerequisites

What do you need before attempting Half Butterfly to Dogfight?

  • Deep underhook on the butterfly hook side, arm threaded around opponent’s torso reaching toward their far shoulder or lat
  • Butterfly hook actively loaded with foot planted on the mat and shin angled under opponent’s inner thigh for maximum elevation leverage
  • Half guard legs maintaining firm squeeze on opponent’s trapped leg with no slack that would allow extraction
  • Body turned onto the side facing the opponent rather than flat on back, creating proper alignment for the diagonal drive upward
  • Head positioned inside the opponent’s body (not crossfaced to the outside) with forehead or temple against their chest

Execution Steps

How do you execute Half Butterfly to Dogfight step by step?

  1. Establish deep underhook: Thread your arm deep around the opponent’s torso on the butterfly hook side, reaching toward their far shoulder or lat. Fight past any frames or overhook attempts to get maximum depth. The deeper this underhook penetrates, the more control and leverage you generate throughout the entire transition.
  2. Load the butterfly hook: Plant your butterfly hook foot firmly on the mat with your heel drawn toward your own hip, creating a loaded spring position. Your shin should angle under the opponent’s inner thigh so that when you extend your hip, the hook lifts their weight directly upward. Ensure the hook is positioned for maximum mechanical advantage.
  3. Turn onto your side: Rotate your torso toward the opponent so your chest faces their side rather than pointing at the ceiling. This angle alignment is essential because it converts your hip extension into forward-and-upward drive rather than pushing ineffectively straight up into the opponent’s weight.
  4. Initiate coordinated elevation: Simultaneously extend your hips through the butterfly hook and drive forward with your underhook arm. These two force vectors—upward from the hook and diagonal from the underhook—create combined momentum that disrupts the top player’s base and brings you toward your knees. Time this with the opponent’s weight shift for maximum effect.
  5. Rise to kneeling position: Come up to your inside knee while keeping the half guard squeeze tight on the opponent’s trapped leg. Your outside leg posts with the foot flat on the mat to establish your base. Drive your head firmly into the opponent’s chest or shoulder throughout the rise to prevent them from crossfacing you back down to the mat.
  6. Secure forward pressure in dogfight: Once kneeling, immediately deepen your underhook and press your head and upper chest into the opponent’s body. Establish the dogfight configuration by fighting for superior head position—your head should be level with or above theirs. Drive constant forward pressure to prevent them from settling into a stable whizzer counter.
  7. Control far hip and initiate offense: Use your free hand to grip the opponent’s far hip, belt line, or waistband to prevent them from circling away or establishing a deep whizzer. This control point completes the dogfight entry and immediately sets up your first offensive action—whether a sweep, back take attempt, or further positional improvement.

Opponent Counters

How might your opponent counter Half Butterfly to Dogfight?

  • Top player drives heavy crossface and sprawls hips back to flatten bottom player during elevation attempt (Effectiveness: High) - Your Response: If you feel the crossface coming, accelerate your elevation and turn harder into the opponent rather than trying to rise straight up. Use the butterfly hook to lift sharply and redirect their sprawl pressure. If already flattened, abandon the dogfight attempt and work back to proper half butterfly frames before retrying. → Leads to Flattened Half Guard
  • Top player establishes deep whizzer overhook and uses it to peel the underhook while driving shoulder pressure (Effectiveness: Medium) - Your Response: When you feel the whizzer locking in, continue driving forward rather than pulling back. A committed forward drive makes the whizzer less effective. If the whizzer is too deep, consider transitioning to deep half guard by ducking under or switching to an electric chair entry that uses the whizzer against the opponent. → Leads to Half Butterfly
  • Top player backsteps or shifts weight laterally to avoid the elevation and begin extracting their trapped leg (Effectiveness: Medium) - Your Response: Follow the backstep by adjusting your angle and maintaining the half guard squeeze. If they create enough space, transition your butterfly hook to a different guard entry point such as single leg X or deep half rather than forcing the dogfight. Use their lateral movement as an opportunity to off-balance them in the direction they are already moving. → Leads to Half Butterfly

Common Attacking Mistakes

What mistakes should you avoid when executing Half Butterfly to Dogfight?

1. Attempting to rise without establishing a deep underhook first

  • Consequence: Without the underhook as your primary control anchor, the top player can easily crossface you back to the mat or strip your upper body connection, leaving you in a worse position than where you started
  • Correction: Always secure the underhook as the first step in the transition sequence. If you cannot get the underhook, work on grip fighting and re-pummeling before attempting any elevation

2. Rising straight upward instead of driving diagonally into the opponent

  • Consequence: A vertical rise creates space between you and the opponent, allowing them to insert frames, establish crossface, or begin passing. You end up elevated but without connection or control
  • Correction: Drive at a diagonal angle—forward and up simultaneously—so that as you rise, you close distance and apply pressure. Your underhook and head should make contact with the opponent throughout the entire movement

3. Releasing the half guard squeeze during the elevation phase

  • Consequence: The top player extracts their trapped leg and immediately begins passing, often completing the pass before you can recover guard since you are now in an awkward half-risen position
  • Correction: Consciously maintain the half guard leg squeeze throughout the transition. The trapped leg is your anchor point—without it, the dogfight position cannot be established. Drill the rise with emphasis on leg tension

4. Not loading the butterfly hook before attempting to come up

  • Consequence: Without the loaded spring position, you lack the elevation power to disrupt the top player’s base. The transition becomes a pure arm-and-neck strength battle that favors the top player’s gravity advantage
  • Correction: Before initiating the rise, ensure your butterfly hook foot is planted on the mat with your heel drawn toward your hip. The hip extension through this loaded hook provides the primary elevation force

5. Allowing head to drop below opponent’s chest level during the rise

  • Consequence: Low head position invites the crossface and allows the top player to drive your head to the mat, killing the transition and flattening you into a worse half guard position
  • Correction: Drive your head firmly into the opponent’s chest or shoulder throughout the rise. Your head should travel upward with your body, maintaining constant pressure against their torso to prevent the crossface

6. Initiating the transition when the top player has already consolidated heavy chest pressure and crossface

  • Consequence: Trying to rise against an established heavy top position burns significant energy and has very low success probability, often resulting in being flattened worse than before the attempt
  • Correction: First use frames and the butterfly hook to disrupt the top player’s pressure and create space. Only initiate the dogfight entry when you have broken their weight distribution and created enough room to thread the underhook

Training Progressions

How do you train Half Butterfly to Dogfight (Attacker)?

Phase 1: Isolated Mechanics - Underhook-to-elevation coordination Partner provides zero resistance from half butterfly top. Practice the complete sequence: establish underhook, load hook, turn, elevate, secure dogfight. Focus on smooth coordination between the underhook drive and butterfly hook elevation. Perform 20 repetitions per side, emphasizing body mechanics over speed.

Phase 2: Timing and Entry Recognition - Reading opponent’s weight shifts for optimal entry windows Partner applies light passing pressure (30-40%) from half butterfly top and randomly shifts weight for passing attempts. Practice recognizing when the weight shift creates an opening for the dogfight entry. Develop sensitivity to the moments when the top player is most vulnerable to being elevated.

Phase 3: Overcoming Defensive Resistance - Executing against crossface and whizzer counters Partner actively defends the dogfight entry with realistic crossface and whizzer resistance at 60-70% intensity. Practice adjusting your entry based on the specific counter—driving through whizzers, redirecting around crossfaces, and chaining failed attempts into alternative positions like deep half guard.

Phase 4: Live Integration and Chaining - Flowing from dogfight entry into offensive chains Full positional sparring starting from half butterfly bottom. Focus on executing the dogfight entry and immediately chaining into sweeps or back takes rather than pausing in dogfight. Track success rate across rounds and identify which counters you struggle with most for targeted practice.

Safety Considerations

What are the safety concerns for Half Butterfly to Dogfight?

This transition involves rising from a supine position to kneeling under an opponent’s weight, which places stress on the neck and lower back. Avoid explosive jerking movements without proper underhook security, as sudden load changes can strain the cervical spine or shoulder joint. Partners should communicate when applying heavy crossface pressure during drilling to prevent neck compression injuries. When training the butterfly hook elevation, gradually increase resistance to allow the body to adapt to the loading patterns. Tap immediately if neck pressure becomes excessive during failed attempts.
