Single-Leg X

Ashi-style open guard that isolates one leg with a figure-four — the main highway into ankle locks and modern heel hooks.

Overview

Single-leg X (SLX) wraps one of the opponent’s legs in a figure-four while your hips stay under their base. It is one of the most important modern open-guard structures because it creates sweeps, stand-up entries, and high-percentage paths into straight ankle locks and heel hooks.

Position Flow

How to Enter

  • Transition from X-guard by releasing the far hook and tightening the near figure-four
  • Enter from seated open guard when you catch a stepping lead leg
  • Recover from half guard or scramble positions by inserting the outside hook first

How to Exit

  • Straight ankle lock when the foot is controlled and hips are aligned
  • Heel hook entries when rules allow and the heel is exposed
  • Technical stand-up sweep to come up on the single leg
  • Fifty-fifty when they turn and both legs entangle

Key Controls

  • Figure-four on the trapped leg with your outside foot on their hip or rib line
  • Inside knee/shin connection that keeps their knee from escaping outside
  • Hand fight on the free leg, sleeve, or ankle to stop them clearing the entanglement

Vulnerabilities

  • Opponent knees down and smash-passes before the figure-four locks
  • Backstep clears that free the trapped knee
  • Your own exposed heel if secondary control is lazy

Ideal When

You want a tight single-leg entanglement that connects open-guard retention to leg-lock offense.

OffenseOffense

Goals

  • Pin the knee line and own the foot before they plant
  • Force a choice between giving the sweep and defending the leg attack

Key Techniques

  • Straight ankle lock from classic ashi alignment
  • Inside/outside heel hook when competition rules permit
  • Stand-up to single-leg takedown finish off broken base

Pro Tips

  • Hide your own free leg; SLX fails when the passer attacks your exposed heel first
  • Elevate or off-balance before finishing — static SLX against a heavy base stalls

Common Mistakes

  • Crossing feet without hip connection under their weight
  • Hunting heel hooks before knee-line control is real
DefenseDefense

Goals

  • Clear the outside hook and put a knee on the mat
  • Keep the trapped foot from being cupped for ankle locks

Key Techniques

  • Knee-down base with posture to kill elevation
  • Backstep or long-step to free the trapped knee
  • Hand fight to hide the heel and peel figure-four control

Pro Tips

  • Address the hip hook early; late reactions feed the ankle lock
  • Do not hop on one foot over a locked SLX

Common Mistakes

  • Pulling away and handing them a cleaner ashi angle
  • Reaching both hands to the trapped foot while losing posture
Variations
Standard single-leg X under a standing opponentSLX to fifty-fifty when they turn inboundOutside ashi variations that change heel-hook direction
Key Concepts
  • SLX is control of one leg plus your own safety on the other
  • Knee line first, foot second, finish third
  • Sweeps and submissions should threaten together
Recommended Drills
  • Open-guard to SLX entry reps with cooperative stepping
  • Ankle-lock alignment drills from a static SLX hold
  • SLX retention rounds where the passer only tries to knee-down and clear

Summary

Single-leg X isolates one leg, elevates their base, and opens a short menu of finishes. Lock the figure-four, protect your free leg, then choose sweep or leg attack based on how they defend the foot.
