Williams Guard Bottom is an innovative open guard position characterized by controlling the opponent’s arm with a shoulder lock grip while maintaining guard structure. Named after creator Roy Williams, this position combines elements of traditional guard retention with a unique shoulder manipulation that creates both offensive and defensive opportunities. The practitioner on bottom secures the opponent’s arm in a shoulder lock configuration while using their legs to maintain distance and create angles for sweeps and submissions. This guard is particularly effective against opponents who attempt aggressive passing strategies, as it neutralizes their posting ability and creates immediate submission threats. Williams Guard exemplifies the evolution of modern BJJ guard systems by integrating joint manipulation with positional control, forcing opponents into defensive reactions that open sweep opportunities. The position functions as a systematic approach where the shoulder lock serves as both submission threat and positional control mechanism, channeling opponent responses into predictable patterns that each open specific attacking opportunities. Understanding the relationship between shoulder lock pressure and hip angle creates a dynamic threat environment where opponents can never settle into defensive posture.
Position Definition
- Bottom practitioner controls opponent’s arm in shoulder lock configuration with figure-four grip or similar shoulder manipulation, creating constant submission threat while maintaining positional control through integrated joint lock and guard retention mechanics
- Bottom practitioner maintains active guard structure with legs positioned to create distance frames that prevent passing attempts, using hip movement and leg engagement to generate sweeping leverage while simultaneously reinforcing shoulder lock control
- Opponent’s controlled arm is isolated and manipulated away from their centerline through shoulder lock mechanics, disrupting their base and limiting their ability to establish pressure or complete guard passes by reducing available posting points
- Bottom practitioner’s hips remain mobile and able to angle away from opponent’s pressure while maintaining shoulder lock control, creating dynamic position for transitions between submission attempts, sweep executions, and positional improvements
Prerequisites
- Successful grip establishment on opponent’s arm with shoulder lock configuration
- Opponent positioned in standing or combat base within guard range
- Bottom practitioner has space to establish leg frames and maintain distance
- Isolation of opponent’s arm away from their defensive grips
Key Defensive Principles
- Maintain constant shoulder lock pressure to create submission threat and control opponent’s movement
- Use legs actively to create distance and prevent opponent from establishing chest-to-chest pressure
- Angle hips away from opponent’s free arm while keeping controlled arm isolated
- Transition between shoulder lock variations based on opponent’s defensive reactions
- Create sweeping opportunities when opponent attempts to defend shoulder lock
- Maintain grip integrity throughout transitions to prevent opponent from recovering arm
- Use opponent’s attempts to free their arm as triggers for sweeps and position advancement
