What is the Deep Half Guard?
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
Ideal When
You need an under-the-hips half-guard game that creates sweeps without winning a classic underhook battle on top.
Offense
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
Defense
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.
