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?
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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
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.
