What is the optimal knee orientation for loosening the lockdown during leg circulation?

Point the trapped knee toward the mat. This narrows the leg profile by reducing the surface area available for the lockdown's figure-four configuration to grip. A narrow leg profile makes the lock progressively looser with each circulation movement, whereas keeping the knee pointed outward maintains the wide profile that the lockdown is designed to control.

Why must the underhook be neutralized before committing to lockdown clearance?

The underhook provides the leverage engine for the whip-up motion and sweep threats. If you clear the lockdown while the underhook remains active, the bottom player can re-establish the lockdown during your transition, execute an Old School sweep using underhook leverage, or advance to back control. Neutralizing the underhook with a whizzer or crossface removes the upper body manipulation that makes the Vaporizer dangerous.

Your opponent successfully re-locks the lockdown after your first extraction attempt - how do you adjust your approach?

Return to knee-toward-mat orientation and increase shoulder pressure to limit their ability to reposition. Consider switching to the backstep extraction variant, which changes the extraction angle and often catches the bottom player off-guard. Also evaluate whether your underhook neutralization was sufficient - re-locking often indicates the bottom player retained enough upper body control to manipulate your leg back into the figure-four.

What conditions must exist before transitioning from lockdown clearance to the passing phase?

Both the lockdown leg entanglement and the upper body control (underhook or overhook) must be neutralized. Your crossface or whizzer must be established firmly enough that the bottom player cannot re-establish their underhook during the pass. Your base must be wide enough to resist any last-moment sweep attempt. Only when all three conditions are met should you commit to the knee-across-hip passing motion.

Your opponent begins increasing whip-up pressure and threatening the Electric Chair as you start extraction - what is your immediate response?

Abandon the extraction temporarily and drive your weight back with hips heavy and low. The Electric Chair requires hip elevation and leg separation, so keeping hips heavy directly counters the setup. Widen your base to resist the lateral rolling that accompanies the Electric Chair entry. Once the immediate threat subsides, restart extraction from this more stable defensive position rather than trying to rush through the danger.

What is the critical timing window between lockdown clearance and pass completion?

The window is immediate and cannot tolerate any pause. The moment your foot clears the figure-four configuration, you must drive your knee across their hip line while maintaining crossface pressure. Any delay allows the bottom player to re-insert their knee for half guard retention, re-engage the lockdown, or transition to a different guard. The extraction-to-pass must be one continuous flowing motion.

Pass Vaporizer Position Attacker | BJJ Technique Guide

Passing the Vaporizer from top requires a methodical approach that prioritizes base stability and systematic lockdown clearance over speed. The attacker must first neutralize the whip-up pressure through base widening and shoulder pressure, then address the lockdown through controlled leg circulation movements that gradually degrade the figure-four configuration. Rushing the pass creates opportunities for the bottom player to sweep or advance to more dangerous positions like the Electric Chair or Truck. The successful passer treats this as a multi-phase operation: stabilize, neutralize upper body control, clear the lockdown, then advance to side control.

Key Attacking Principles

What are the key principles for executing Pass Vaporizer Position?

Address lockdown and upper body control simultaneously rather than isolating one control point at a time
Use controlled leg circulation with knee-toward-mat orientation rather than explosive yanking that tightens the lockdown reflexively
Maintain heavy shoulder pressure throughout extraction to limit bottom player’s ability to re-adjust controls or generate whip-up power
Widen base immediately when sensing whip-up pressure to create a stable platform resistant to lateral rolling
Transition to passing position only after both lockdown and underhook controls have been neutralized
Stay patient and grind through the position rather than creating space through explosive movements that benefit the bottom player

Prerequisites

What do you need before attempting Pass Vaporizer Position?

Stable wide base established despite lockdown entanglement, with free leg posted wide for lateral stability
Whizzer or crossface control established against bottom player’s underhook to neutralize whip-up leverage
Shoulder pressure driving into bottom player’s chest or face to limit their hip mobility and offensive adjustments
Recognition that lockdown has loosened slightly or that bottom player’s upper body control has weakened, creating a viable extraction window

Execution Steps

How do you execute Pass Vaporizer Position step by step?

Establish defensive base: Widen your base by sprawling your free leg out to the side and lowering your hips. Drive heavy shoulder pressure into the bottom player’s chest using your crossface arm. This creates the stable platform needed to resist whip-up attempts while you work the extraction.
Neutralize the underhook: Counter the bottom player’s underhook with a deep whizzer, threading your arm over theirs and driving your weight through the overhook position. Alternatively, establish a strong crossface that prevents them from using the underhook effectively. The underhook is the engine of their whip-up motion and must be addressed before lockdown clearance.
Begin lockdown degradation: Point your trapped knee toward the mat to narrow the leg profile. This makes the figure-four configuration harder to maintain as the narrow profile reduces the friction surfaces the lockdown depends on. Simultaneously shift your weight slightly toward the trapped leg side to increase downward pressure on their lock.
Circulate the trapped leg: Using small controlled movements, work your trapped heel toward your buttock while maintaining the knee-to-mat orientation. Each circulation creates incremental looseness in the lockdown. Avoid large explosive movements that trigger the bottom player’s tightening reflex. Think of slowly unscrewing a bolt rather than ripping it free.
Extract the leg from lockdown: Once sufficient looseness exists, pull your foot through the lockdown gap by driving your knee forward and away from their entanglement. Maintain constant shoulder pressure during extraction to prevent the bottom player from re-establishing the lock. The moment your foot clears their figure-four, immediately post it wide to prevent re-engagement.
Secure passing position: With the lockdown cleared, immediately drive your knee across their hip line while maintaining crossface pressure. Do not allow any space between extraction and pass completion. The bottom player will attempt to re-guard or insert a knee for half guard retention during this transition window.
Establish side control: Complete the pass by settling your chest perpendicular to their torso with your hips low and heavy. Secure crossface control with your forearm across their neck and block their far hip with your near hand. Sprawl your legs behind you to distribute weight and prevent guard recovery. Consolidate the position before initiating any attacks.

Opponent Counters

How might your opponent counter Pass Vaporizer Position?

Bottom player re-establishes lockdown by hooking foot behind knee during extraction (Effectiveness: High) - Your Response: Immediately return to knee-toward-mat orientation and restart the circulation process. Increase shoulder pressure to limit their ability to reposition the lock. Consider switching to the backstep extraction variant if they successfully re-lock multiple times. → Leads to Vaporizer
Bottom player executes Old School sweep during weight shift, using posted hand as fulcrum (Effectiveness: Medium) - Your Response: Widen base in the opposite direction of their sweep and drive crossface pressure harder. If sweep begins completing, post your free hand wide and work to re-establish top position in half guard rather than fighting the full sweep. → Leads to Half Guard
Bottom player inserts knee for half guard retention as lockdown clears (Effectiveness: Medium) - Your Response: Immediately transition to standard half guard passing sequence. Use crossface and underhook to flatten them before attempting knee slice or pressure pass. The critical window is preventing the knee shield from being established. → Leads to Half Guard
Bottom player increases whip-up pressure and threatens Electric Chair during extraction attempt (Effectiveness: High) - Your Response: Abandon extraction temporarily and address the whip-up by driving weight back and widening base. Keep hips heavy to prevent the leg split required for Electric Chair. Once the immediate threat passes, restart extraction from a more stable position. → Leads to Vaporizer

Common Attacking Mistakes

What mistakes should you avoid when executing Pass Vaporizer Position?

1. Attempting explosive leg extraction instead of controlled circulation

Consequence: Triggers bottom player’s lockdown tightening reflex, creates space for sweeps, wastes energy, and often results in an even tighter entanglement than before the attempt
Correction: Use slow controlled circulation movements with knee-toward-mat orientation, treating extraction as a gradual loosening process over 15-30 seconds rather than a single explosive motion

2. Addressing only the lockdown while ignoring the underhook

Consequence: Even with the leg partially free, bottom player uses underhook to generate whip-up, re-establish lockdown, or transition to sweep before pass can be completed
Correction: Neutralize underhook with whizzer or crossface control before committing to lockdown clearance. Both controls must be degraded simultaneously for the pass to succeed

3. Maintaining narrow base during extraction attempts

Consequence: Whip-up motion easily rolls you laterally, resulting in Old School sweep completion or transition to bottom player’s Electric Chair sequence
Correction: Widen base immediately by sprawling free leg out to the side, creating a wide stable platform that resists lateral rolling forces

4. Pausing between lockdown clearance and pass completion

Consequence: Creates a gap where bottom player re-inserts knee for half guard, re-establishes lockdown, or transitions to alternative guard position that restarts the passing problem
Correction: Flow directly from leg extraction into knee-across-hip passing motion without any pause. The transition must be seamless to prevent re-guarding

5. Driving weight forward aggressively to pressure through the position

Consequence: Forward weight commitment elevates hips and plays directly into Electric Chair setup, making leg separation significantly easier for the bottom player
Correction: Distribute weight through shoulder pressure while keeping hips mobile and positioned back. Forward drive should come from the chest and shoulders, not from hip commitment

6. Posting hand close to bottom player’s hip during base establishment

Consequence: Creates a leverage point the bottom player uses to complete the Old School sweep, using your posted hand as a fulcrum for the rolling motion
Correction: Post hands wide and away from bottom player’s hips, maintaining them positioned for lateral stability support rather than close proximity that provides sweep leverage

Training Progressions

How do you train Pass Vaporizer Position (Attacker)?

Phase 1: Lockdown Mechanics Understanding - Understanding the lockdown configuration and how it generates control Partner establishes full lockdown and you practice identifying the figure-four configuration, understanding where the control surfaces are, and feeling how the lock tightens and loosens based on leg orientation. No pass attempts yet, purely tactile awareness development.

Phase 2: Isolation Drills - Practicing individual pass components separately Drill each component in isolation: base widening against whip-up (partner provides whip-up pressure only), underhook neutralization (partner fights for underhook only), leg circulation (lockdown only, no upper body fighting). Build muscle memory for each element before combining.

Phase 3: Combined Sequence with Cooperative Partner - Executing the full pass sequence against light resistance Partner establishes full Vaporizer and provides 30-50% resistance. Practice the complete sequence from base establishment through side control consolidation. Perform 10 complete repetitions per side, focusing on smooth transitions between phases rather than speed.

Phase 4: Progressive Resistance and Counter Training - Handling defensive reactions and counters during the pass Partner increases resistance to 75-100% and actively counters with re-locking, sweep attempts, and Electric Chair threats. Practice recognizing counters and adjusting the pass sequence in real-time. Complete 5-minute rounds with full positional sparring from the Vaporizer starting position.

Safety Considerations

What are the safety concerns for Pass Vaporizer Position?

This pass involves controlled leg extraction from an entanglement that places stress on the knee and ankle joints. Avoid explosive twisting motions that could strain the trapped knee. If the lockdown creates sharp pain in the knee joint, tap and reset rather than forcing through the extraction. Partners should release lockdown pressure immediately upon tap. During training, communicate about knee sensitivity before drilling and use gradual progressive resistance rather than starting at full intensity.
