SAFETY: Kimura from Quarter Guard targets the Shoulder joint, rotator cuff, and shoulder capsule. Risk: Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis). Release immediately upon tap.
Attacking the Kimura from Quarter Guard requires integrating submission mechanics with passing pressure. The top player must recognize the moment when the bottom player’s arm becomes vulnerable—typically during underhook attempts or framing sequences—and transition smoothly from pass-focused pressure to figure-four grip control. The key advantage of this position is that your weight distribution and crossface already restrict the defender’s escape options, allowing you to focus on wrist isolation and rotational finishing mechanics rather than fighting for positional control. The quarter guard creates a natural funnel where the bottom player’s defensive arm movements expose the exact angles needed for kimura entry, making this one of the highest-percentage submission setups available during guard passing sequences.

Key Attacking Principles
What are the key principles for executing Kimura from Quarter Guard?
- Control the wrist before committing to the figure-four—premature grip attempts telegraph your intention and allow preemptive defense
- Maintain crossface pressure throughout the kimura setup to prevent the bottom player from turning into you or creating defensive frames
- Pin the captured elbow tight against your hip to create a fixed fulcrum point, maximizing rotational leverage while minimizing escape angles
- Use your body weight and hip rotation to drive the finish rather than arm strength—the kimura is a whole-body submission, not an arm crank
- Keep your base low and wide during the finishing sequence to resist the bottom player’s bridge and roll escape attempts
- Attack the arm during transitions—the moment the bottom player extends for an underhook or frame is the highest-percentage entry window
Prerequisites
What do you need before attempting Kimura from Quarter Guard?
- Established quarter guard top position with crossface control preventing opponent from turning into you
- Bottom player’s near arm exposed through underhook attempt, frame, or failed grip fighting
- Your hips advanced past opponent’s centerline with weight distributed forward through chest and shoulder
- Free hand available to secure wrist control while maintaining positional pressure through shoulder weight
- Opponent’s far shoulder pinned to mat through crossface, limiting their ability to rotate away from the attack
Execution Steps
How do you execute Kimura from Quarter Guard step by step?
- Identify arm exposure window: From established quarter guard top with crossface pressure, watch for the bottom player’s near arm extending as they reach for an underhook, create a frame against your chest, or attempt to push against your hip. This momentary extension creates the grip access needed for the kimura entry. (Timing: Immediate recognition within 1-2 seconds of arm exposure)
- Secure wrist control with far hand: Release your far-side hand from hip control and grip the bottom player’s exposed wrist using a C-grip with your thumb pointing toward their fingers. Maintain shoulder pressure through crossface to compensate for releasing the hip control grip during this transition. (Timing: 0.5-1 second transition, maintaining pressure throughout)
- Thread arm for figure-four grip: Slide your crossface-side arm underneath the bottom player’s trapped forearm from the outside, threading between their arm and their torso. Connect your threading hand to your own wrist that holds their wrist, establishing the complete figure-four configuration with your forearm pressing against the back of theirs. (Timing: 1-2 seconds for clean threading without rushing)
- Pin the elbow to your hip: Drive the bottom player’s captured elbow tight against your hip bone using the figure-four grip, creating a fixed fulcrum point. This pinning action prevents them from straightening the arm and establishes the mechanical advantage needed for rotational finishing pressure. (Timing: Immediate after figure-four locks)
- Establish finishing angle: Shift your body weight slightly toward the bottom player’s head while keeping your chest heavy on their upper body. This angle adjustment opens the rotational path needed to drive their wrist toward the mat while maintaining control over their torso and preventing escape. (Timing: 1-2 seconds for weight redistribution)
- Apply controlled rotational pressure: Using hip rotation and body weight rather than arm strength alone, drive the bottom player’s wrist in a paintbrush arc toward the mat behind their head. Maintain the elbow pin throughout the rotation as the shoulder enters progressively deeper internal rotation toward the submission finish. (Timing: 3-5 seconds of slow progressive rotation in training)
- Complete the finish and release on tap: Continue smooth progressive rotational pressure until the opponent taps. Keep your base wide and weight heavy through the final phase to resist any last-attempt bridge escapes. Release immediately upon feeling or hearing the tap signal and return the arm gently to neutral position. (Timing: Immediate release upon tap signal)

Opponent Defenses
How might your opponent defend against Kimura from Quarter Guard?
- Straighten the arm to prevent figure-four lock from closing (Effectiveness: High) - Your Response: Maintain wrist grip and use chest pressure to drive the arm back into bent position, or transition to straight armbar since their extended arm is now vulnerable to hyperextension → Leads to Quarter Guard
- Grab own shorts or belt with trapped hand to anchor wrist against rotation (Effectiveness: Medium) - Your Response: Increase chest pressure to limit anchoring capability, then use circular figure-four motion at changing angles the grip cannot sustain, or bump their gripping hand free with your knee → Leads to Quarter Guard
- Bridge and roll toward the trapped arm to disrupt base and break grip (Effectiveness: Medium) - Your Response: Widen base by stepping far leg out and dropping weight through chest onto upper body to flatten opponent back down, or follow the roll direction maintaining grip to finish from new angle → Leads to Half Guard
- Turn aggressively into attacker to reduce available rotational angle (Effectiveness: Low) - Your Response: Increase crossface pressure to flatten them back or follow their rotation to maintain the finishing angle, adjusting your hip position to preserve the rotational path as they turn → Leads to Half Guard
