The Defend Vaporizer Sweep attacker is the top player caught in the Vaporizer position who must neutralize the bottom player’s sweep attempts while systematically clearing the lockdown entanglement. This requires coordinated defensive responses across multiple threat vectors including the Old School sweep, rolling back takes, and Electric Chair transitions. The attacker must manage their base width, shoulder pressure placement, and hip positioning simultaneously to deny the bottom player the momentum and leverage needed for sweep completion. Success depends on recognizing which specific sweep is being attempted, applying the precise countermeasure at the optimal timing window, and then transitioning into lockdown clearing mechanics that lead to half guard top extraction. The defensive mindset must be active rather than passive, using controlled adjustments and constant pressure rather than explosive reactions that create the space the bottom player needs for their attacks.

Key Attacking Principles
What are the key principles for executing Defend Vaporizer Sweep?
- Widen base immediately upon detecting whip-up motion by sprawling the free leg laterally to create a stable platform resistant to rolling forces
- Apply heavy chest-to-chest shoulder pressure into the bottom player to limit their hip mobility and reduce whip-up effectiveness
- Address the lockdown through controlled leg circulation and knee positioning rather than explosive extraction that tightens the entanglement
- Counter the underhook with a whizzer or crossface to neutralize the upper body leverage essential for sweep completion
- Distribute weight to simultaneously defend against both the Old School sweep direction and the rolling back take direction
- Maintain patient grinding defensive pressure rather than explosive movements that waste energy and create space for the bottom player’s attacks
Prerequisites
What do you need before attempting Defend Vaporizer Sweep?
- Top player is trapped in Vaporizer position with one leg caught in the bottom player’s lockdown figure-four configuration
- Bottom player has initiated or is actively threatening a sweep through whip-up motion, foot posting, or rolling mechanics
- Top player retains sufficient base and posting ability to initiate a defensive response before the sweep is completed
- Top player can identify the direction and type of sweep being attempted to select the appropriate counter technique
- Upper body positioning allows for shoulder pressure application or whizzer establishment against the bottom player’s underhook
Execution Steps
How do you execute Defend Vaporizer Sweep step by step?
- Recognize sweep direction and type: Identify whether the bottom player is attempting an Old School sweep using a lateral roll with posted foot and underhook, a rolling back take rotating toward Truck position, or an Electric Chair entry splitting your legs while driving upward. The specific defense depends entirely on reading the correct threat in time to apply the appropriate counter.
- Widen base and lower center of gravity: Immediately sprawl your free leg out to the side opposite the sweep direction, posting your foot wide on the mat. Lower your hips toward the mat to drop your center of gravity, making it significantly harder for the bottom player to generate the rotational momentum needed to complete the sweep attempt.
- Drive shoulder pressure into opponent’s chest: Commit heavy shoulder pressure into the bottom player’s upper chest and shoulder area, pinning them flat and limiting their ability to generate the hip drive necessary for the whip-up motion. This pressure also prevents them from turning to their side, which is essential for most sweep completions from the Vaporizer.
- Neutralize upper body control with whizzer or crossface: Counter the bottom player’s underhook by establishing a deep whizzer on their underhook arm or driving a crossface to control their head position. Without their underhook functioning as a lever, the sweep loses its primary upper body driving mechanism and becomes significantly less threatening overall.
- Begin controlled lockdown clearing sequence: Point your trapped knee toward the mat to narrow the profile of your leg within the lockdown. Use controlled leg circulation movements, rotating your foot in small circles while shifting your weight side to side. Work your heel progressively toward your buttock, creating the angle needed to slip your foot free from the figure-four configuration.
- Extract trapped leg while maintaining pressure: As the lockdown loosens from your circulation work, pull your knee through the gap while keeping constant shoulder pressure on the bottom player. Do not lift your weight to extract the leg as this creates space for re-establishment. Slide the leg free using the angle you created rather than pulling directly backward.
- Establish standard half guard top position: Once your leg clears the lockdown, immediately transition to standard half guard top with proper crossface and weight distribution. Maintain heavy pressure through the transition to prevent the bottom player from recovering the lockdown or transitioning to a different guard variation. Consolidate position before initiating any passing sequence.

| Counter | Half Guard | 20% |
Opponent Counters
How might your opponent counter Defend Vaporizer Sweep?
- Bottom player transitions to Electric Chair by releasing lockdown and controlling far leg when top player widens base (Effectiveness: High) - Your Response: Keep far knee tucked tight and legs together when widening base. If they begin splitting your legs, immediately squeeze knees together and drive hips forward to prevent the separation needed for Electric Chair entry → Leads to Half Guard
- Bottom player switches to rolling back take toward Truck position when top player commits shoulder pressure forward (Effectiveness: Medium) - Your Response: Turn hips toward the bottom player rather than away when you feel rotational force. Establish a whizzer and drive weight into their chest to prevent the roll from gaining momentum. If they begin to secure the far leg hook, immediately address the back take threat → Leads to Half Guard
- Bottom player tightens lockdown and increases whip-up pressure from a different angle after initial defense (Effectiveness: Medium) - Your Response: Maintain widened base and continue systematic lockdown clearing. The re-established whip-up is less effective once center of gravity is lowered. Continue patient leg circulation and avoid reverting to a narrow base that enables renewed sweep attempts → Leads to Vaporizer
- Bottom player releases underhook to reach for far leg, threatening sweep by attacking base directly (Effectiveness: Low) - Your Response: When they release the underhook, immediately drive crossface pressure and accelerate lockdown clearing. Their base attack without the underhook has significantly less power, and the loss of upper body control weakens their overall position → Leads to Vaporizer
Safety Considerations
What are the safety concerns for Defend Vaporizer Sweep?
When defending Vaporizer sweeps, be mindful of medial collateral ligament stress on the trapped knee during lockdown clearing. Avoid explosive twisting motions that can strain knee ligaments. If you feel sharp pain in the trapped knee during extraction attempts, stop immediately and tap. During training, communicate with partners about lockdown tightness and agree on resistance levels before drilling. The lockdown can apply significant force to the knee joint, particularly when combined with rotation during sweep defense.
