State Description

The 50/50 Guard is a symmetrical leg entanglement position where both practitioners mirror each other with their legs intertwined, each person’s leg positioned across the opponent’s hip line. Named for the theoretically equal positioning of both competitors, this position represents one of the most technical and controversial positions in modern Brazilian Jiu-Jitsu due to its potential for both high-level leg attacks and strategic stalemates.

In the 50/50 Guard, both people occupy essentially the same position - each has one leg trapped across the opponent’s hips while the other leg triangles around the opponent’s trapped leg. This symmetry creates unique strategic dynamics where small positional advantages become magnified. The position gained prominence in the 2000s and 2010s through practitioners like the Mendes brothers and later the Danaher Death Squad, who demonstrated its effectiveness as both a control position and a submission platform.

The position’s reputation is divided: traditionalists view it as a stalling position that can lead to referee standups, while modern leg lock specialists recognize it as a highly technical position with multiple submission entries and transition opportunities. Success in 50/50 requires understanding subtle grip fighting, hip positioning, and the ability to recognize and exploit momentary advantages. Under IBJJF rules, certain submissions from this position are restricted by belt level, making it crucial to understand both technical execution and competitive legality.

Visual Description

Both you and your opponent are lying on your sides or slightly on your backs, facing each other with your legs symmetrically entangled in a mirrored configuration. Your right leg (assuming standard right-sided 50/50) extends across your opponent’s hip and outside of their body, while your left leg threads inside their legs, hooking around their right leg with your foot positioned near or behind their hip. Your opponent’s leg configuration mirrors yours exactly, creating a locked position where neither person can easily extract their leg without the other’s cooperation or a technical advantage.

Your upper bodies may be upright or lying back depending on the stage of attack, with your hands fighting for control of each other’s feet, ankles, and toes to set up leg attacks. Hip positioning is crucial - your hips should be mobile and perpendicular to your opponent’s centerline to maximize leverage for submissions. The trapped leg between you creates a natural barrier and control point, while the outside leg provides leverage and control of your opponent’s hip. Both practitioners are equally at risk of ankle locks, heel hooks (in no-gi), and other leg attacks, making grip fighting and positional awareness paramount in this symmetrical battleground.

Key Principles

  • Break Symmetry First: Success comes from creating asymmetrical advantages through superior foot control, hip positioning, or leg elevation
  • Active Engagement Required: Passive play leads to stalemate and referee intervention; constantly threaten submissions or transitions
  • Foot Control Hierarchy: Controlling opponent’s foot while preventing their control of yours is the primary strategic goal
  • Hip Mobility: Mobile hips allow you to create angles for submissions and prevent opponent’s attacks
  • Grip Fighting Dominance: Superior grips on opponent’s foot and ankle enable submission entries and prevent their offense
  • Transition Sensitivity: Recognize when direct submissions aren’t available and seamlessly flow to superior positions like Saddle or Backside 50/50

Expert Insights

John Danaher: “The 50/50 position represents a fascinating study in asymmetry within symmetry. While the position appears equal, small advantages in foot control, hip positioning, and leg elevation create decisive offensive opportunities. The key principle is understanding that the 50/50 is not a destination but rather a gateway to superior positions - specifically the Saddle position (also called 411 or honey hole). When someone achieves clean foot control in the 50/50, they have a mechanical advantage that, when properly exploited through hip movement and leg elevation, leads to the strongest leg attack position in grappling.”

Gordon Ryan: “In competition, I use the 50/50 as a control position that forces opponents into bad decisions. Most people either stall in 50/50 or try to clear it desperately, both of which play into my strategy. I’m constantly looking to transition to the Saddle position, which I consider far superior. The straight ankle lock from 50/50 is effective at lower levels, but against high-level opponents, I’m using it as a control position while working toward either heel hooks (in no-gi) or transitioning to X-Guard for sweeps. The position became controversial because people use it to stall, but that’s not how it should be used - it’s a transition hub.”

Eddie Bravo: “At 10th Planet, we’ve integrated the 50/50 into our system, but we approach it differently than pure leg lockers. For us, it’s often a transition position when attacking the truck or when coming back from inverted positions. We’ll use the 50/50 as a temporary control position but we’re always working toward either the calf slicer (in no-gi) or transitioning to the truck position where we have more submission options. The position is valuable but you can’t be static - you have to constantly threaten and move, otherwise you’re just giving the ref a reason to stand you up.”

Common Errors

  • Error: Equal or passive positioning

    • Consequence: Creates stalemate where neither person can advance, resulting in referee standup or wasted energy.
    • Correction: Actively work to break symmetry by controlling opponent’s foot, elevating their leg, or transitioning to superior positions.
    • Recognition: If both you and opponent are static for more than 10-15 seconds without attempting techniques, you’re being too passive.

  • Error: Loose leg control

    • Consequence: Allows opponent to easily extract their leg or reverse position, losing your positional advantage.
    • Correction: Keep your legs tightly locked around opponent’s leg with active squeeze pressure, maintaining constant connection throughout.
    • Recognition: If you feel opponent’s leg moving freely or creating space, tighten your leg triangle and hip connection.

  • Error: Ignoring opponent’s grips

    • Consequence: Permits opponent to control your foot and ankle, setting up their own submissions effectively.
    • Correction: Fight for superior grips on opponent’s foot while denying their attempts to control yours, establishing grip dominance.
    • Recognition: If opponent secures clean grips on your foot while you have no grips on theirs, you’ve lost the grip battle.

  • Error: Attempting illegal techniques

    • Consequence: Results in disqualification or penalties in competition depending on ruleset and belt level.
    • Correction: Know the legal submissions for your ruleset - heel hooks typically illegal in gi and at lower belt levels in IBJJF.
    • Recognition: Before training or competing, verify which leg locks are legal for your belt level and ruleset.

  • Error: Poor hip positioning

    • Consequence: Reduces submission leverage and allows opponent to clear the position or establish superior control.
    • Correction: Keep your hips mobile and positioned perpendicular to opponent’s hip line, maximizing your leverage for leg attacks.
    • Recognition: If you can’t create pressure on opponent’s foot or they can easily face you squarely, your hip angle is wrong.

  • Error: Focusing only on leg attacks

    • Consequence: Misses transition opportunities to superior positions when leg attacks aren’t immediately available.
    • Correction: Recognize when to transition to Saddle, Backside 50/50, or X-Guard based on opponent’s defensive reactions.
    • Recognition: If you’re stuck attempting the same submission repeatedly without success, it’s time to transition.

  • Error: Neglecting positional awareness

    • Consequence: Loses track of match position, time, or points, making tactical errors in competition.
    • Correction: Maintain awareness of score, time remaining, and position on the mat while fighting in 50/50.
    • Recognition: In competition, if you’re winning on points, maintaining 50/50 may be strategic; if losing, you need to be more aggressive or transition.

Training Drills

  • Grip Fighting from 50/50: Start in established 50/50 and engage in isolated grip fighting for foot control, with partner defending at 60-70% intensity, performing 2-minute rounds with role switching. Focus on hand fighting patterns and grip breaking strategies while maintaining leg entanglement.

  • 50/50 to Saddle Transitions: Practice the transition from 50/50 to Saddle position by elevating opponent’s trapped leg, drilling 15 repetitions on each side with partner offering moderate resistance (50%). Emphasize hip movement, leg elevation, and maintaining control throughout transition.

  • Symmetry Breaking Sequences: Starting from equal 50/50, practice creating asymmetrical advantages through foot control, hip movement, or leg positioning, performing 20 total repetitions of different breaking methods. Focus on recognizing which method works best against different defensive postures.

  • Submission Chains from 50/50: Drill flowing between straight ankle lock, calf slicer, and transitions to other positions based on opponent’s reactions, completing 25 total transitions with partner defending at 40-60% intensity. Develop ability to recognize and exploit defensive movements.

  • Positional Sparring: Start in 50/50 and engage in position-specific sparring where attacker works for submissions or positional advancement while defender works to clear or stalemate, 5-minute rounds with role switches. Emphasize active engagement and transition recognition.

  • Entry and Re-entry Sequences: Practice entering 50/50 from various positions (X-Guard, Single Leg X, De La Riva) and re-establishing it when opponent attempts to clear, 10 repetitions from each starting position. Build ability to maintain leg entanglement game throughout dynamic exchanges.

Optimal Submission Paths

Direct submission path (no-gi legal): 50-50 Guard → 50 → Won by Submission Reasoning: When heel is exposed and heel hooks are legal, this is highest percentage finish, success rate 35-60% depending on skill level

Positional advancement path: 50-50 Guard → 50 → Saddle Position → Heel Hook → Won by Submission Reasoning: Transitioning to Saddle creates superior control before finishing, success rate 38-60% for transition, 55-85% for finish from Saddle

Safe gi-legal path: 50-50 Guard → Straight Ankle Lock → Won by Submission Reasoning: Legal at all belt levels in gi competition, success rate 20-65% depending on skill level

Sweep to dominance path: 50-50 Guard → X-Guard Entry → X-Guard → Sweep to Top → Top Position → Mount → Submission Reasoning: When leg submissions aren’t working, transitioning to sweeping game establishes positional dominance

System-based path (Danaher methodology): 50-50 Guard → 50 → Saddle Position → Inside Heel Hook → Won by Submission Reasoning: Systematic progression to strongest leg attack position before finishing, emphasis on positional hierarchy

Competition strategy path (when winning on points): 50-50 Guard → Maintain position → Time expires → Win by points Reasoning: 50/50 can be used strategically to control match tempo and protect lead, though this is controversial approach
