As the attacker executing the Underhook Sweep from Dogfight, you are the bottom player in a dogfight position who has established a deep underhook and is looking to convert that grip advantage into a complete positional reversal. Your primary task is to use the underhook as a lever to rotate the opponent over their trapped knee while simultaneously removing their far-side posting ability. The sweep requires coordinating three elements: forward pressure through the underhook, far-side base removal with your free hand, and explosive leg drive from your outside posting leg. Timing is critical—the sweep works best when the opponent’s weight is neutral or shifting backward, not when they are driving forward with heavy whizzer pressure. Read the opponent’s weight distribution through tactile feedback in the underhook and initiate the sweep during windows of compromised balance.

Key Attacking Principles
What are the key principles for executing Underhook Sweep from Dogfight?
- Depth of underhook determines sweep leverage—a shallow underhook to the near hip provides insufficient rotational force to complete the sweep
- Remove far-side posting ability before initiating the primary drive; sweeping without controlling the far side allows easy defense through posting
- Use leg power through your outside posting leg as the primary force generator, not upper body pulling through the underhook arm
- Angle the driving force diagonally across the opponent’s body rather than straight forward to attack their weakest balance plane
- Commit fully once initiated—half-committed sweeps allow the opponent to recover base and potentially counter with flattening pressure
- Head position drives body direction; keep your head pressed tight against the opponent’s chest or shoulder, driving in the direction of the sweep
Prerequisites
What do you need before attempting Underhook Sweep from Dogfight?
- Deep underhook established with your arm reaching around the opponent’s torso to at minimum their far lat, ideally reaching the far shoulder blade for maximum leverage
- Elevated kneeling posture in dogfight with hips off the mat and weight distributed through both knees and your outside posting leg
- Free hand positioned to control the opponent’s far hip, far knee, or far ankle to prevent posting during the sweep
- Outside leg firmly planted on the mat with the ball of the foot engaged, ready to generate explosive forward and diagonal driving force
- Opponent’s whizzer pressure manageable and not fully collapsing your posture—if the whizzer is overwhelming, address it first before attempting the sweep
Execution Steps
How do you execute Underhook Sweep from Dogfight step by step?
- Verify underhook depth and adjust: Confirm your underhook arm has penetrated deep around the opponent’s torso. Your hand should reach their far lat or shoulder blade. If shallow, re-pummel to deepen the grip before proceeding. A shallow underhook lacks the rotational leverage needed to complete the sweep against resistance.
- Establish far-side control with free hand: Reach your free hand across to control the opponent’s far hip, far knee, or far ankle. The specific target depends on distance—grab whatever far-side anchor is available. This control point is critical as it prevents the opponent from posting their far leg or hand to stop the sweep.
- Load outside posting leg for drive: Position your outside leg with the ball of the foot firmly planted on the mat, knee bent at approximately 90 degrees. This leg serves as your primary force generator. Shift your weight slightly backward to load the leg like a spring before the explosive drive phase.
- Drive head into opponent’s chest and angle body: Press your head firmly into the opponent’s chest or shoulder on the underhook side. Angle your body slightly toward the direction you intend to sweep—diagonally across the opponent’s centerline rather than straight forward. This diagonal angle attacks a weaker balance plane.
- Execute explosive forward-diagonal drive: Simultaneously drive off your outside leg, pull with the underhook, and lift or block the far-side post. The force should travel diagonally through the opponent’s body, rotating them over their trapped knee. Commit maximum explosive power—this is the decisive moment of the sweep.
- Maintain far-side control through the rotation: As the opponent begins to tip, maintain your free hand’s control on their far side throughout the rotation. Releasing the far-side grip prematurely allows them to post and recover even mid-sweep. Keep pulling or lifting their far-side anchor until they are past the tipping point.
- Follow through to top position: Continue driving through the sweep until you land in a dominant top position. Do not stop at the tipping point or pause mid-sweep. Your momentum should carry you into side control or mount depending on how far the rotation travels. Keep your chest connected to the opponent throughout.
- Consolidate top position immediately: Upon landing in the top position, immediately establish crossface control or underhook and drive your weight through your hips into the opponent. Free your inside leg from the half guard entanglement if it remains trapped. Secure dominant grips before the opponent can re-guard or scramble away.

| Failure | Dogfight Position | 30% |
| Counter | Flattened Half Guard | 15% |
Opponent Counters
How might your opponent counter Underhook Sweep from Dogfight?
- Opponent posts far hand wide on the mat to create a tripod base against the sweep direction (Effectiveness: High) - Your Response: Switch immediately to back take as the wide post exposes their far side—circle your underhook to seatbelt grip and drive toward their exposed back rather than continuing the sweep → Leads to Dogfight Position
- Opponent drives forward aggressively with whizzer and crossface to flatten you before the sweep initiates (Effectiveness: High) - Your Response: Redirect their forward momentum into a deep half guard entry by ducking under their pressure, or absorb the drive momentarily and explode into the sweep as their weight shifts forward past their base → Leads to Flattened Half Guard
- Opponent hip switches away from the underhook and circles their hips to neutralize the leverage angle (Effectiveness: Medium) - Your Response: Follow the hip switch with your underhook, maintaining chest-to-chest contact, and re-angle your sweep direction to match their new hip orientation—their movement creates a new off-balance angle to exploit → Leads to Dogfight Position
- Opponent sits back heavily, dropping their weight low to create a wide stable base resistant to forward drives (Effectiveness: Low) - Your Response: Their backward weight shift opens the forward drive sweep—use the space created by their retreat to drive straight forward through their weakened base, or transition to the inside trip variation targeting their now-lightened near leg → Leads to Dogfight Position
Safety Considerations
What are the safety concerns for Underhook Sweep from Dogfight?
The Underhook Sweep involves explosive forward driving pressure channeled through the underhook grip. Avoid excessive rotational force on the opponent’s trapped knee during the sweep. Control the descent when the opponent falls to prevent impact injuries to their head, shoulder, or elbow. During training, communicate with your partner about the intensity of the drive. Be mindful of knee stress on the inside leg that remains trapped in the half guard configuration during rotation. When drilling, start at low intensity and increase gradually.
