Deep Half Guard
Half-guard entanglement that gets underneath the passer’s hips — a high-percentage path to waiter sweeps, back takes, and single-leg entries.
Overview
Deep half guard puts your head and shoulders under the opponent’s hips while you control one leg. From underneath their base you can elevate for waiter-style sweeps, come up on a single leg, or take the back when they post and turn.
Position Flow
How to Enter
- Dive under from regular half guard when you win the underhook and clear their cross-face
- Enter from butterfly by capturing one leg and sliding your head to the far hip
- Recover from a knee-cut attempt by threading underneath before they settle chest-to-chest
How to Exit
- Waiter sweep by elevating and rolling them over the trapped side
- Technical stand-up to a single-leg when their base posts wide
- Back take when they turn away to kill the elevation
- Return to knee-shield half if the underhook battle is lost
Key Controls
- Head under the hip line with your shoulder supporting their weight
- Figure-four or clamp on the trapped leg so they cannot extract the knee
- Far-arm control (underhook, wrist, or belt) to stop them sprawling heavy
Vulnerabilities
- Heavy sprawl and cross-face that flatten you before you get under the hip
- Twister or crucifix risks if you linger with a poor head position
- Opponent extracting the trapped leg and mounting while you are inverted
Ideal When
You need an under-the-hips half-guard game that creates sweeps without winning a classic underhook battle on top.
OffenseOffense
Goals
- Get fully underneath the hip before they pin your near shoulder
- Force a post that opens waiter, single-leg, or back-take finishes
Key Techniques
- Waiter sweep to come up in top half or side control
- Single-leg finish when they stand to escape elevation
- Back takes off turnaways and overcommits
Pro Tips
- Head position under the hip is the position — grips are secondary
- Keep the trapped knee pinched; a loose deep half becomes smash pass fuel
Common Mistakes
- Diving under without clearing the cross-face
- Hunting sweeps while still beside the hip instead of under it
DefenseDefense
Goals
- Sprawl hips back and win the cross-face before they get under
- Extract the trapped knee or smash-pass to mount/side
Key Techniques
- Heavy hip sprawl with near-side underhook
- Knee extraction and mount when their head is shallow
- Backstep or long-step clears once the figure-four loosens
Pro Tips
- Do not stand tall over a locked deep half
- Kill elevation first; then free the leg
Common Mistakes
- Posting both hands on the mat and feeding the waiter sweep
- Turning away and presenting the back
Variations
Classic deep half under a seated or kneeling passerDeep half to waiter sweep chainsDeep half to single-leg X when they stand
Key Concepts
- Under the hip beats beside the hip
- Deep half is an elevation system, not a lockdown stall
- Every post they make is a sweep or back-take cue
Recommended Drills
- Half-guard to deep-half entry reps with progressive cross-face pressure
- Waiter-sweep elevation drills to a controlled top position
- Retention rounds where the passer only tries to sprawl and extract
Summary
Deep half works when you are truly under the hips. Clear the cross-face, clamp the leg, elevate, and choose waiter, single-leg, or back take based on how they post.
