SAFETY: Kimura from Half Guard targets the Shoulder joint and rotator cuff. Risk: Rotator cuff tear (supraspinatus, infraspinatus tendons). Release immediately upon tap.
The Kimura from Half Guard is one of the most versatile shoulder locks in Brazilian Jiu-Jitsu, applicable from both top and bottom positions. From bottom half guard, the Kimura serves as a powerful sweep, back take, and submission threat that capitalizes on the opponent’s commitment to passing. The technique exploits the natural underhook battle that occurs in half guard, transforming defensive frames into offensive attack chains. The submission targets the shoulder joint through a figure-four grip configuration, creating rotational pressure on the glenohumeral joint and surrounding connective tissue. What makes this variation particularly effective is its capacity to create dilemmas: opponents must choose between defending the submission, preventing the sweep, or stopping the back take. This multi-threat system exemplifies modern half guard strategy, where single techniques branch into complete attacking sequences based on defensive reactions.

Key Attacking Principles
What are the key principles for executing Kimura from Half Guard?
- Control before submission - Establish figure-four grip and positional control before applying rotational pressure
- Hip connection - Maintain hip-to-hip connection to prevent opponent from rolling forward and escaping
- Elbow isolation - Keep opponent’s elbow tight to their body and away from mat to prevent posting
- Progressive rotation - Apply shoulder rotation gradually in training, allowing partner time to recognize danger
- Multiple threat integration - Use Kimura as entry point for sweeps, back takes, and submission chains
- Grip hierarchy - Prioritize figure-four completion over positional advancement until grip is secure
- Weight distribution - Shift weight to prevent opponent’s hip escape while maintaining submission control
Prerequisites
What do you need before attempting Kimura from Half Guard?
- Establish underhook on opponent’s arm from bottom half guard position
- Opponent commits weight forward or attempts to flatten you out
- Secure wrist control with your free hand (2-on-1 grip configuration)
- Create enough space to swim figure-four grip through
- Opponent’s trapped arm is away from their body and vulnerable
- Your legs maintain half guard control preventing immediate escape
- Head positioning controls opponent’s upper body preventing forward pressure
Execution Steps
How do you execute Kimura from Half Guard step by step?
- Establish Underhook and Wrist Control: From bottom half guard, establish a deep underhook on opponent’s far arm while they attempt to crossface or consolidate top position. With your free hand, grip their wrist of the underhook arm (creating 2-on-1 control). This initial control prevents them from withdrawing the arm and sets up the figure-four entry. Keep your head tight to their chest to prevent them from driving forward with shoulder pressure. (Timing: Initial setup phase)
- Create Space and Swim Figure-Four: Create a small frame with your underhook side elbow against their hip while pulling their wrist across your centerline. This generates the space needed to swim your underhook hand through and grab your own wrist, completing the figure-four grip. The opponent’s arm should form roughly a 90-degree angle at the elbow. Ensure their elbow stays tight to their body (not posting on mat) which maintains vulnerability. (Timing: 2-3 seconds)
- Secure Figure-Four and Hip Connection: Lock in the figure-four grip configuration with your palm-to-palm or wrist-to-wrist connection. Simultaneously close distance and reconnect your chest to their chest, eliminating space they could use to roll forward. Your half guard legs should be actively controlling their trapped leg. This hip-to-hip connection is critical - without it, they can granby roll forward and escape before you can apply pressure. (Timing: 1-2 seconds)
- Walk Shoulders to Perpendicular Angle: Using small hip movements and shoulder walking, begin to angle your body perpendicular to your opponent (creating an ‘L’ shape with your bodies). This changes the angle of attack on their shoulder joint and prepares multiple finishing options. Keep their elbow isolated close to their ribs throughout this movement. If they resist by driving into you, this creates the back take opportunity; if they pull away, it opens the sweep. (Timing: 2-3 seconds)
- Create Shoulder Rotation Decision Point: Begin applying slow, controlled rotation to their shoulder by pulling their wrist toward their back while keeping their elbow stationary near their ribs. In training, this rotation should be extremely progressive (3-5 seconds). The opponent faces a trilemma: defend the Kimura (exposing their back), base out with their free hand (opening sweep), or roll with the pressure (entering the submission sequence). Monitor their reactions carefully. (Timing: 3-5 seconds progressive application)
- Finish or Transition Based on Defense: If opponent remains stationary and doesn’t tap: continue rotation until they tap (in training, stop at 70-80% rotation). If they turn into you to relieve pressure: release half guard, secure seat belt grip, and take the back. If they post their free hand to prevent rotation: use that posting as a pivot point to execute the Kimura sweep to top position. If they roll forward: follow them over, maintaining the Kimura grip and establishing top control or continuing submission in the scramble. (Timing: Variable based on opponent response)

Opponent Defenses
How might your opponent defend against Kimura from Half Guard?
- Opponent grabs their own belt or gi pants to prevent figure-four completion (Effectiveness: High) - Your Response: Control their wrist first with both hands, break the defensive grip by extending their arm away from their body, then quickly swim your figure-four through before they can re-grip → Leads to Half Guard
- Opponent rolls forward over their trapped shoulder to escape rotational pressure (Effectiveness: Medium) - Your Response: Maintain figure-four grip throughout their roll, release half guard, and follow them to their back. You’ll arrive in turtle or back control with Kimura grip still intact. This often leads to the back take or armbar transition → Leads to game-over
- Opponent posts free hand on mat and drives weight through it to prevent rotation (Effectiveness: Low) - Your Response: Use their posted hand as a pivot point to execute the Kimura sweep. Hip escape to create angle, use your legs to elevate their trapped side, and sweep them over their posted arm to achieve top position while maintaining the Kimura grip → Leads to game-over
- Opponent pulls their elbow tight to their body and hunches forward to minimize rotation range (Effectiveness: Medium) - Your Response: This defensive posture often exposes their back. Transition to the back take by releasing your half guard, getting your bottom hook in, and securing seat belt control. Alternatively, use the Kimura grip to off-balance them and set up alternative submissions → Leads to game-over
- Opponent explosively withdraws their arm before figure-four is secured (Effectiveness: High) - Your Response: If they successfully pull their arm free early, transition immediately to alternative attacks like the guillotine (if their head is low) or re-establish half guard control and restart the sequence. Prevention is better: secure wrist control early and don’t commit to figure-four until proper setup → Leads to Closed Guard
