As the defender against the Kimura Counter via Roll, you are the top player in a Kimura Trap position who has been working to extract your arm or advance past the bottom player’s guard. When the bottom player recognizes their Kimura grip is failing, they will attempt to roll into closed guard rather than simply lose position. Your objective is either to prevent the roll entirely, keeping them in the deteriorating Kimura Trap where you can continue extracting your arm, or to capitalize on the rolling motion to advance your position beyond what the Kimura Trap normally allows. Understanding this technique’s mechanics allows you to read the setup, time your defensive response, and convert the bottom player’s transitional vulnerability into positional advancement. The roll creates a brief window where the bottom player’s legs are neither in half guard nor closed guard—exploiting this window is the key to successful defense.
Opponent’s Starting Position: Kimura Trap (Bottom)
How to Recognize This Attack
- Bottom player’s Kimura grip pressure shifts from upward (toward submission) to lateral (across their body), indicating redirection into roll
- Bottom player plants their outside foot flat on the mat, establishing a posting point for bridge-to-rotation movement
- Hip angle changes from static control to loading for explosive bridge, with the bottom player’s hips shifting toward you
- Bottom player’s free hand moves from framing position to reaching for your collar or behind your head, preparing post-roll grips
Key Defensive Principles
- Recognize pre-roll indicators early to prepare defensive positioning before the rolling motion begins
- Maintain heavy hip pressure and base to deny the bottom player the space needed to generate rotational momentum
- Control the Kimura grip hand and wrist to prevent the bottom player from redirecting grip energy into the roll
- Post and widen base when you feel rotational force beginning, creating a tripod that resists the rolling vector
- Capitalize on the transition window when the bottom player’s legs are in between positions and vulnerable to passing
- Drive forward through the roll attempt rather than retreating, as forward pressure collapses the rotational mechanics
Defensive Options
1. Post free hand wide and sprawl hips back to kill rotational momentum
- When to use: When you feel the first signs of lateral grip redirection and hip loading before the roll fully initiates
- Targets: Kimura Trap
- If successful: Roll attempt is stuffed and bottom player remains in Kimura Trap with a now-weaker grip, allowing continued arm extraction or guard passing
- Risk: If you post too wide, you may expose your back to a back take if they redirect to a different Kimura Trap technique
2. Drive forward with heavy crossface pressure to flatten their hips and deny bridging space
- When to use: When bottom player begins loading their hips for the bridge that powers the roll
- Targets: Kimura Trap
- If successful: Bottom player’s hips are flattened, eliminating the space needed for any rolling or sweeping motion from the Kimura Trap
- Risk: Excessive forward drive can be redirected into a Rolling Kimura sweep if the bottom player maintains strong grip
3. Strip the Kimura grip during the transition window when hands are changing configuration
- When to use: During the brief moment when the bottom player begins releasing the Kimura grip to transition to closed guard grips
- Targets: Half Guard
- If successful: Bottom player loses both Kimura control and fails to establish closed guard, leaving them in half guard without offensive grips
- Risk: Timing must be precise—attempting too early when grip is still strong wastes your extraction effort
4. Backstep over their legs during the roll to prevent closed guard establishment and advance to side control
- When to use: When the roll is already in motion and prevention is no longer possible, capitalize on their legs being in transition
- Targets: Half Guard
- If successful: You bypass the closed guard entirely and land in half guard top or side control, converting their recovery attempt into position loss
- Risk: Mistimed backstep can result in you falling into their closed guard with poor posture, worsening your position
Best-Case Outcomes for Defender
→ Half Guard
Capitalize on the transition window when the bottom player’s legs are releasing from half guard hooks but have not yet closed around your waist. Strip the weakening Kimura grip with a sharp two-on-one break, then immediately drive your knee across their thigh line to establish half guard top before their legs can reconnect. Use your freed arm to crossface and flatten them, consolidating half guard top where the failed roll has left them without grips or defensive structure.
→ Kimura Trap
Prevent the roll entirely by recognizing the setup cues and immediately sprawling your hips back while posting your free hand wide. Drive heavy shoulder pressure into their chest to flatten their hips against the mat, eliminating the bridge space needed to generate roll momentum. Maintain forward crossface pressure and continue methodically extracting your arm from the now-weakened Kimura grip.
Test Your Knowledge
Q1: What are the earliest recognition cues that your opponent is about to attempt the Kimura Counter via Roll? A: The four primary cues are: their Kimura grip pressure shifting from upward toward submission to lateral across their body, their outside foot planting flat on the mat as a bridging post, their hips loading and shifting toward you in preparation for explosive rotation, and their free hand moving from framing to reaching for your collar or head. Seeing any two of these simultaneously indicates an imminent roll attempt and should trigger immediate defensive positioning.
Q2: How should you position your hips to resist the rolling motion effectively? A: Drop your hips heavy and forward, sprawling your legs back at approximately 45 degrees to create a wide, low base. Your hip bone should press into their torso, pinning them flat and eliminating the space they need for the bridge that initiates the roll. Avoid keeping your hips high or square, as this creates the elevation gap the bottom player exploits. The lower and heavier your hips, the more force they need to generate rotation.
Q3: Your opponent initiates the roll but you feel their legs starting to swing around your waist - what is your immediate response? A: Immediately backstep your far leg over their swinging legs before they can lock ankles behind your back. Simultaneously, drive your near knee across their hip line to block the leg closure. If you cannot prevent the ankle lock, posture up explosively the instant their ankles cross, establishing hands on their hips before they can break your posture. The first two seconds after guard closure determine whether you can posture and begin opening or get broken down.
Q4: How do you use your arm extraction to prevent the roll rather than fuel it? A: Extract your arm with steady, controlled pressure rather than explosive jerking. Maintain constant forward chest pressure while methodically straightening your elbow and rotating your wrist toward their thumb line—the weakest point of any grip. The key is removing your arm without creating the energy spike the bottom player redirects into roll momentum. Think slow constant pressure rather than sudden explosive pulling.
Q5: What is the most advantageous position to achieve when the roll attempt fails mid-transition? A: Half guard top with crossface control is the most advantageous realistic outcome. When the roll stalls mid-transition, the bottom player’s legs are between half guard and closed guard—neither fully locked nor fully free. Drive your knee through this gap to establish half guard top, immediately crossface to flatten them, and begin passing. They will be grip-less and structurally compromised from the failed roll, making the pass significantly easier than from a stable Kimura Trap.
