The Escape Vaporizer Defender is the top player in the Vaporizer who recognizes that the bottom player is attempting to release their lockdown and transition to open guard. While the lockdown release benefits the defender by freeing their trapped leg, the transition creates a tactical opportunity to advance position rather than passively allowing the bottom player to re-establish guard. The defender’s primary objective is to capitalize on the brief vulnerability window during the lockdown release—this is the moment when the bottom player’s defensive structure is weakest, and aggressive forward pressure or immediate passing attempts have the highest success rate. Understanding the mechanics of the bottom player’s escape sequence allows the defender to time their counter-attacks precisely to exploit the transitional gaps between lockdown control and open guard establishment.
Opponent’s Starting Position: Vaporizer (Bottom)
How to Recognize This Attack
- The lockdown pressure on your trapped leg decreases noticeably or the figure-four configuration loosens around your ankle
- Bottom player’s underhook becomes less aggressive, shifting from pulling you down to pushing or framing against your shoulder
- Bottom player begins scooting their hips backward or angling away from you rather than driving the whip-up motion forward
- You feel the bottom player’s feet beginning to uncross from the lockdown figure-four position around your leg
- A new forearm frame appears on your shoulder or neck that was not there during the active Vaporizer phase
Key Defensive Principles
- Recognize the early signs of lockdown release and prepare to advance position rather than passively accepting the transition to open guard
- Drive forward pressure the instant you feel the figure-four loosening to prevent the bottom player from establishing foot frames on your hips
- Control the bottom player’s hips and legs before they can place feet on your body and create the distance needed for open guard
- Maintain chest-to-chest contact through the transition window to prevent the creation of open guard space
- Use the previously trapped leg to immediately establish a passing angle or drive through half guard rather than pulling it backward
- Transition immediately from lockdown defensive mindset to guard passing mindset the moment the lockdown configuration begins to loosen
Defensive Options
1. Drive forward immediately with heavy chest-to-chest pressure before foot frames can be established on your hips
- When to use: The instant you recognize the lockdown loosening and before the bottom player inserts their foot on your hip
- Targets: Flattened Half Guard
- If successful: You flatten the bottom player and establish pressure half guard top or advance directly to side control through the transitional gap
- Risk: If timed poorly while the lockdown is still partially engaged, the bottom player may use your forward momentum to execute a sweep
2. Grab opponent’s ankles or pant legs to prevent foot placement on your hips and control their leg positioning
- When to use: When you feel the lockdown releasing but the opponent has already begun inserting foot frames and forward pressure alone will not prevent guard establishment
- Targets: Lockdown
- If successful: You prevent open guard establishment and force the opponent to either re-lock the position or accept an inferior guard configuration
- Risk: Reaching for ankles can compromise your base if the opponent still maintains a deep underhook with pulling power
3. Immediately initiate knee slice pass through the opening created by the lockdown release using your previously trapped leg
- When to use: When the lockdown releases and your weight is already positioned over one of the opponent’s legs with a passing angle available
- Targets: Flattened Half Guard
- If successful: You pass directly through the transitional gap before open guard is established, achieving side control or dominant half guard top
- Risk: A committed knee slice can be countered with a quick underhook if the bottom player maintains their upper body connection throughout the transition
4. Sprawl hips back and establish ankle or pant grips to set up toreando pass from standing position
- When to use: When the lockdown releases and you want to create a standing passing position rather than engaging in close-range half guard battle
- Targets: Flattened Half Guard
- If successful: You establish a dominant grip configuration for toreando or leg drag passing from a standing position with superior control
- Risk: Creating distance may allow the bottom player to establish full open guard with active feet and upper body grips
Best-Case Outcomes for Defender
→ Flattened Half Guard
Capitalize on the lockdown release by driving immediate forward pressure before foot frames are established. Use the previously trapped leg to cut through the transitional gap with a knee slice or drive forward for a pressure pass. Maintain chest-to-chest contact throughout to prevent the bottom player from creating the distance needed for open guard recovery.
→ Lockdown
Prevent the escape by controlling the bottom player’s legs as they attempt to release the figure-four. Grab ankles or pant legs to prevent foot placement on your hips. Drive your weight forward to make frame establishment difficult while maintaining your previously trapped leg in close contact to allow lockdown re-establishment.
Test Your Knowledge
Q1: What is the optimal moment to initiate forward pressure when defending against the Escape Vaporizer? A: The optimal moment is when you first feel the figure-four loosening but before the bottom player has placed their foot on your hip. This is the critical vulnerability window—the lockdown is releasing but no defensive frame has been established yet. Driving forward at this precise moment catches the bottom player between positions, preventing them from completing the transition to open guard. Waiting even two seconds too long allows frame establishment that makes passing significantly harder.
Q2: Why should you advance your previously trapped leg forward rather than pulling it backward when the lockdown releases? A: Advancing the leg forward maintains pressure on the bottom player and immediately positions you for passing. The leg should become a passing tool—cutting through for a knee slice or driving forward for a pressure pass. Pulling the leg backward creates space between you and the opponent, which is exactly what they need to establish open guard frames and distance. Your previously trapped leg transitions from liability to weapon in one smooth forward motion.
Q3: How do you balance capitalizing on the lockdown release with defending against the underhook the bottom player still maintains? A: Address the underhook simultaneously with your forward pressure. As you drive forward, establish a whizzer or crossface with your near arm to neutralize the underhook’s pulling power. Do not ignore the underhook to chase ankle grips—a live underhook during a positional scramble gives the bottom player sweep opportunities that can reverse the position entirely. The correct sequence is: feel release, drive forward, establish crossface or whizzer, then advance passing position.
Q4: Your opponent releases the lockdown and successfully places both feet on your hips—what passing sequence should you initiate? A: Once feet are on your hips, the transition to open guard is largely complete and you must shift to standard open guard passing strategy. Strip one foot off your hip by pushing the knee to the side while maintaining your other hand on their collar or wrist for posture control. Alternatively, grip both pant legs at the knees and initiate a toreando pass by directing their legs to one side while stepping around. Act quickly before they establish upper body grips that complete the full open guard configuration.
