Pocket Half Guard Bottom is a specialized half guard variant characterized by a deep underhook on the opponent’s far side combined with tight hip connection and the trapped leg locked between your legs. The ‘pocket’ refers to the space created by pulling the opponent’s far shoulder down with the underhook while using your bottom leg to create a frame against their near hip. This position excels at generating powerful sweeps and back-takes because the deep underhook compromises the opponent’s base while the tight leg control prevents them from advancing to mount or establishing a strong passing position.
The position gained prominence through the 10th Planet system and has been refined by competition specialists who recognize its effectiveness against pressure passers. Unlike standard half guard where the underhook may be shallow, Pocket Half Guard demands a deep underhook that reaches across the opponent’s back, ideally gripping their far lat or armpit. This depth allows you to control their upper body rotation and create powerful off-balancing mechanics. The bottom leg creates a ‘pocket’ or wedge against the opponent’s hip, providing both defensive framing and offensive leverage for sweeps.
Pocket Half Guard Bottom is particularly effective against opponents who favor heavy pressure passing or who attempt to flatten you in half guard. The deep underhook and hip frame prevent them from establishing chest-to-chest pressure, while the leg configuration maintains enough space to generate hip movement and rotational power for sweeps. Advanced practitioners use this position as a launching point for the Old School Sweep, back-takes, and transitions to Deep Half Guard or X-Guard variations.
Position Definition
What is Pocket Half Guard (Bottom)?
- Deep underhook secured on opponent’s far side, with your arm reaching across their back to grip their far lat, armpit, or belt, creating significant control over their upper body rotation and preventing them from establishing dominant chest pressure
- Bottom leg (same side as trapped leg) actively framing against opponent’s near hip with foot pressure, creating the characteristic ‘pocket’ space that prevents them from advancing to mount while providing leverage for sweeps and maintaining optimal distance
- Top leg (free leg) locked over opponent’s trapped leg in standard half guard configuration, with knee shield option available or leg threaded beneath their thigh, securing the fundamental half guard lock that prevents them from extracting their leg
- Your bottom shoulder and hip positioned on the mat with active hip mobility maintained, avoiding being completely flattened while keeping enough space to generate rotational power for offensive techniques
- Head position on the underhook side, using head pressure against opponent’s ribs or armpit to reinforce the underhook control and prevent them from stripping your grip or establishing head control
Prerequisites
What do you need before playing Pocket Half Guard (Bottom)?
- Opponent trapped in your half guard with one of their legs secured between both of your legs
- Deep underhook secured on opponent’s far side before they establish heavy chest pressure
- Bottom leg able to create active frame against opponent’s near hip
- Sufficient space and hip mobility to prevent being completely flattened
- Upper body positioning that allows maintenance of underhook depth
Key Defensive Principles
What are the key principles for defending Pocket Half Guard?
- Maintain underhook depth at all costs - shallow underhook compromises all offensive options and allows opponent to establish dominant pressure
- Active bottom leg frame creates the ‘pocket’ space - passive leg allows opponent to flatten you and neutralize sweeping mechanics
- Hip mobility is essential - being completely flattened destroys offensive potential and puts you at risk of being passed
- Head pressure reinforces underhook control - pulling opponent’s shoulder down with combined arm and head pressure prevents their escape
- Use pocket space to generate rotational power - the gap created by bottom leg frame provides leverage for sweeps and off-balancing
- Transition readiness to Deep Half or Old School - Pocket Half Guard serves as a hub position for multiple high-percentage attacks
- Prevent crossface at all costs - opponent’s crossface combined with underhook stripping leads to flattening and successful passing
Decision Making from This Position
What should you do from Pocket Half Guard (Bottom)?
If opponent maintains upright posture and attempts to strip underhook:
- Execute Old School Sweep → Mount (Probability: 65%)
- Execute Back Take from Bottom → Back Control (Probability: 55%)
If opponent drives forward with heavy pressure attempting to flatten:
- Execute Deep Half Entry → Deep Half Guard (Probability: 70%)
- Execute Underhook Sweep from Half → Side Control (Probability: 50%)
If opponent establishes crossface and compromises underhook depth:
- Execute Knee Shield Recovery → Knee Shield Half Guard (Probability: 45%)
- Execute Guard Recovery → Open Guard (Probability: 40%)
If opponent attempts to extract trapped leg by extending it:
- Execute Electric Chair Transition → Electric Chair (Probability: 60%)
- Execute Roll to Truck → Truck (Probability: 55%)
