SAFETY: Kimura from Modified Scarf Hold targets the Shoulder and elbow joint. Risk: Shoulder dislocation or torn rotator cuff from excessive external rotation. Release immediately upon tap.
Executing the Kimura from Modified Scarf Hold requires methodical progression from established pin control through arm isolation to submission finish. The attacker must first consolidate chest pressure and near-arm control before transitioning to the figure-four grip. The key mechanical advantage lies in using your entire body—hips, chest, and arms working as a unified system—to overcome the defender’s single-arm resistance. Proper weight distribution throughout the attack ensures that submission attempts do not compromise positional control, allowing you to return to the pin if the finish is not immediately available. The submission chain from this position is devastating: kimura threats force arm straightening that opens americanas, while americana defense creates deeper kimura entries, producing a self-reinforcing attack cycle.

Key Attacking Principles
What are the key principles for executing Kimura from Modified Scarf Hold?
- Maintain chest pressure throughout the entire submission sequence—never sacrifice positional control for grip acquisition
- Use body mechanics rather than arm strength to generate rotational force on the shoulder joint
- Isolate the elbow from the ribs before attempting any rotational finish—this is the critical control threshold
- Apply progressive, steady pressure rather than explosive cranking to allow safe training and reliable competition finishes
- Treat the kimura grip as a control position first and a submission second—the grip itself creates offensive options
- Chain between kimura and americana based on the defender’s arm angle, converting every defensive reaction into a new attack
Prerequisites
What do you need before attempting Kimura from Modified Scarf Hold?
- Established Modified Scarf Hold with heavy chest-to-chest pressure and near arm controlled
- Opponent’s near arm accessible for figure-four grip—not buried under their body or locked to the far hip
- Sufficient base and weight distribution to maintain control while transitioning both hands to the kimura grip
- Head control or shoulder pressure maintained to prevent opponent from sitting up during grip transition
- Far-side hand free or readily available to complete the figure-four configuration
Execution Steps
How do you execute Kimura from Modified Scarf Hold step by step?
- Consolidate Modified Scarf Hold control: From established Modified Scarf Hold, ensure your chest is heavy on the opponent’s chest with their near arm controlled under your armpit or against your body. Your head should be driving pressure into their face or jaw. Settle your weight and confirm your base is stable before initiating the submission sequence. Rushing this step is the most common reason the attack fails. (Timing: 5-10 seconds to confirm stable control)
- Thread arm under opponent’s near tricep: While maintaining chest pressure, release the head wrap or arm control and slide your near-side arm underneath the opponent’s near-side tricep area. Your forearm threads between their upper arm and their torso, positioning your hand to emerge on the far side of their wrist. Keep your chest heavy throughout this transition to prevent the opponent from creating defensive frames or sitting up. (Timing: 2-3 seconds for smooth threading)
- Secure the figure-four kimura grip: Grab the opponent’s wrist with your threading hand using a thumb-around grip. Simultaneously bring your other hand over the top of their forearm and grip your own wrist, creating the classic figure-four kimura configuration. Both your thumbs should point in the same direction. Lock this grip tight against your chest to create a unified structure that resists grip-fighting attempts. (Timing: 1-2 seconds for decisive grip acquisition)
- Clear the elbow from the ribs: Use your hip pressure and body weight to pry the opponent’s elbow away from their ribcage. Drive your hips forward into their arm while lifting with the figure-four grip to create separation between their elbow and their body. This is often the most contested phase—if their elbow stays connected to their ribs, the finish becomes extremely difficult. Use your near knee to wedge underneath their elbow if necessary. (Timing: 3-8 seconds depending on resistance)
- Pin the upper arm to the mat: Once the elbow clears the ribs, drive the opponent’s upper arm to the mat using downward pressure from your chest and shoulder weight. Position yourself so that your body weight helps pin their upper arm against the ground. This creates the fulcrum point required for the rotational finish and prevents the defender from retracting the arm back toward their body or reconnecting elbow to ribs. (Timing: 1-2 seconds to establish pin)
- Walk the wrist behind the opponent’s back: Begin rotating their forearm behind their back by walking the wrist in small controlled increments toward their far hip and then toward the ceiling. Use your entire upper body turning motion rather than isolated hand movement. Your figure-four grip stays tight while your body rotation generates the torque. Small controlled movements accumulate into irresistible rotational force on the shoulder joint. (Timing: 3-5 seconds of progressive rotation)
- Apply finishing rotational pressure: Continue the external rotation until you meet significant resistance from the shoulder joint reaching its range-of-motion limit. Apply steady, progressive pressure by continuing to walk the wrist behind their back and toward the ceiling. Monitor the opponent’s reactions carefully for tap signals. The shoulder approaches its structural limit before pain fully registers, so apply pressure slowly enough that your partner has time to tap. (Timing: 2-4 seconds of controlled finishing pressure)
- Secure the tap and release safely: Maintain finishing pressure until the opponent signals submission through verbal or physical tap. Once any tap signal is received, release the grip immediately by gently lowering the arm back to a neutral position. Do not drop the arm suddenly. Return to Modified Scarf Hold control or disengage as appropriate for the training or competition context. Check your partner’s shoulder comfort after release. (Timing: Immediate release upon tap signal)

Opponent Defenses
How might your opponent defend against Kimura from Modified Scarf Hold?
- Clasping both hands together to anchor the near arm and prevent figure-four isolation (Effectiveness: High) - Your Response: Wedge your knee between their clasped hands to break the grip, or immediately switch to an americana angle by redirecting the arm toward the mat—their clasped hands actually assist the americana finish → Leads to Modified Scarf Hold
- Straightening the arm to prevent figure-four rotation behind the back (Effectiveness: Medium) - Your Response: Transition immediately to americana as the straightened arm is the ideal starting position for that submission—the opponent is solving your problem for you → Leads to Modified Scarf Hold
- Rolling toward the attacker to relieve rotational pressure on the shoulder (Effectiveness: Medium) - Your Response: Follow the roll maintaining the figure-four grip, transition to mounted kimura position or use the kimura grip to establish back control as they expose their back → Leads to Half Guard
- Explosive bridge during grip transition to create space and retract the arm (Effectiveness: Low) - Your Response: Drive chest pressure down during the bridge and ride it out while maintaining figure-four grip tension—the bridge rarely generates enough force to break an established grip → Leads to Modified Scarf Hold
