The Transition to Reverse Scarf Hold from Kimura Trap Top is a positional advancement technique that converts the figure-four grip control of the Kimura Trap into the crushing chest-compression pin of Reverse Scarf Hold (Ushiro Kesa Gatame). This transition exploits a specific defensive pattern where the opponent tucks their elbow tight and resists the Kimura finish by keeping their arm close to their body. Rather than forcing the submission against a well-defended arm, the top player pivots their hips and rotates their body orientation to face away from the opponent’s head, establishing heavy hip-on-chest pressure while maintaining arm control throughout the movement.
The mechanical basis of this transition centers on hip rotation and pressure transfer. From Kimura Trap Top, the practitioner’s hips are perpendicular to the opponent’s torso with the Kimura grip threatening the shoulder. When the opponent defends effectively by keeping their elbow pinned to their ribs, the top player uses the grip as a pivot point, walking their feet in an arc while rotating their hips 180 degrees to face toward the opponent’s legs. The trapped arm naturally follows this rotation, ending up controlled across the opponent’s body in the classic Reverse Scarf Hold configuration. Throughout this rotation, chest pressure must remain constant to prevent the bottom player from inserting frames or recovering guard.
Strategically, this transition serves a critical role in the Kimura Trap system by providing a high-percentage positional option when the submission is well-defended. It creates a dilemma for the defender: commit to defending the Kimura and risk having position advanced to Reverse Scarf Hold, or loosen the arm defense to prevent the positional change and get caught in the Kimura. This fork in the decision tree is what makes the Kimura Trap system so effective at the purple belt level and above, where opponents are skilled enough to defend individual attacks but struggle against systematic chains that punish every defensive choice.

Playing as Attacker
Key Principles
-
Maintain constant chest-to-chest pressure throughout the entire rotation to prevent opponent from inserting frames or recovering guard
-
Use the Kimura grip as a fixed pivot point around which your body rotates, never releasing or loosening the figure-four during transition
-
Walk feet in small controlled steps rather than large hops to maintain base stability and prevent opponent from exploiting gaps in pressure
-
Keep hips low and heavy on opponent’s torso during the rotation, treating your hip bone as the primary pressure delivery mechanism
-
Time the transition when opponent commits to elbow-tucked Kimura defense, exploiting their defensive posture as the entry window
-
Complete the rotation fully until your body faces opponent’s legs before settling weight, avoiding the half-rotated position that compromises both control and submissions
Execution Steps
-
Confirm Kimura defense and commit to transition: Verify that the opponent has committed to the elbow-tucked Kimura defense by testing the submission …
-
Shift weight to chest and begin foot walk: Transfer your primary weight from your hips to your chest, pressing heavily into the opponent’s uppe…
-
Rotate hips while maintaining grip tension: As your feet walk around, allow your hips to rotate naturally, pivoting around the Kimura grip which…
-
Continue arc past perpendicular position: Walk your feet past the perpendicular (90-degree) angle and continue toward facing the opponent’s le…
-
Settle hips into Reverse Scarf Hold position: Once your body orientation faces toward the opponent’s legs (approximately 180 degrees from starting…
-
Consolidate Reverse Scarf Hold control: Lock in the final pin by ensuring your hip pressure is low and heavy on their chest, your arm contro…
-
Assess immediate submission and transition opportunities: Once control is consolidated, evaluate available attacks based on the opponent’s arm positioning. If…
Common Mistakes
-
Lifting chest off opponent’s torso during hip rotation to create space for the turn
- Consequence: Opponent inserts frames, recovers guard, or creates enough space to escape the pin entirely. The pressure gap allows them to bridge, turn, or insert knees.
- Correction: Keep your chest sliding across their torso throughout the entire rotation. Think of your chest as a rolling pin that never lifts off the dough. Transfer weight to chest before rotating hips so the pressure remains constant.
-
Releasing the Kimura grip prematurely before establishing Reverse Scarf Hold arm control
- Consequence: Loss of arm control creates a window where the opponent can frame, recover defensive posture, or escape to half guard. The transition loses its effectiveness without continuous arm control.
- Correction: Maintain the Kimura grip throughout the entire rotation until your body is fully oriented in Reverse Scarf Hold. Only transition to arm-hugging control after your hips are settled and your base is established in the new position.
-
Taking large steps during the foot walk that create base instability
- Consequence: Large steps create moments of narrow base where the opponent can bridge effectively. Each large step also temporarily lifts hip pressure, creating escape windows.
- Correction: Walk feet in small, controlled increments, keeping your base as wide as possible at all times. Three to four small steps are better than one or two large ones. Your feet should never be closer together than hip-width during the rotation.
Playing as Defender
Key Principles
-
Recognize the transition early by feeling the attacker’s feet begin to walk in an arc around your head and their weight shift from hips to chest
-
Exploit the mid-rotation vulnerability window when the attacker’s base is narrowest and pressure is transitioning between positions
-
Prioritize far-side arm frames against the attacker’s neck or shoulder to block the rotation before it reaches completion
-
Use hip escapes and knee insertion during the rotation to recover guard before Reverse Scarf Hold is consolidated
-
Maintain near-side arm defense even while creating frames, as the Kimura grip remains dangerous throughout the transition
-
React immediately when you feel the pressure pattern change, as waiting until Reverse Scarf Hold is established makes escape dramatically harder
Recognition Cues
-
Attacker’s feet begin walking in small steps in an arc around your head while maintaining Kimura grip, indicating the rotation has started
-
Pressure shifts from the attacker’s hips to their chest on your torso, feeling like a spreading weight rather than a point pressure
-
The Kimura grip pressure changes angle as the attacker’s body rotates, with the figure-four shifting from lateral to diagonal orientation
-
You feel the attacker’s body sliding across your chest rather than pressing straight down, indicating rotational movement
-
The attacker tests the Kimura finish with a brief pull, and when you successfully defend, they immediately begin the foot walk rather than resetting
Defensive Options
-
Insert far-side frame against attacker’s neck or shoulder to block rotation - When: As soon as you feel the foot-walking pattern begin, before the attacker passes the perpendicular angle
-
Hip escape and insert knee shield during mid-rotation vulnerability - When: When the attacker reaches the perpendicular angle and their base is at its narrowest point during the rotation
-
Explosive bridge toward attacker’s head during rotation to destabilize base - When: When you feel the attacker’s weight shifting during the mid-rotation phase and their base is temporarily compromised
Position Integration
This transition occupies a critical junction in the Kimura Trap system’s decision tree. When the Kimura finish is denied, the practitioner has three main options: advance to mount via Side Control to Mount, take the back via Kimura to Back Take, or transition to Reverse Scarf Hold for renewed submission opportunities from a different angle. The Reverse Scarf Hold option is particularly valuable because it maintains the arm control that was already established, provides crushing chest compression that drains the opponent’s energy, and opens new submission chains including americana, arm triangle, and north-south transitions. This creates a continuous offensive cycle where each defensive success by the bottom player simply shifts them into a new threatening position rather than allowing recovery.
