The Underhook War
Half guard is decided by the underhook battle. Whoever wins the underhook — the arm threaded under the opponent's armpit — controls the position. Bottom player with underhook = sweep opportunities. Top player with underhook = smash pass opportunities.
Half Guard Variations
| Variation | Key Feature | Primary Goal |
|---|---|---|
| Basic Half Guard | Z-guard/knee shield | Prevent smash, build to underhook |
| Deep Half Guard | Dive under their hips | Elevator sweep, back take |
| Lockdown | Figure-four the leg | Control movement, old school sweep |
| Knee Shield Half | Knee in their belly | Create space, reach underhook |
Half Guard Sweeps
- Old School Sweep: Lockdown + underhook, crawl out the back while extending lockdown leg
- Waiter Sweep (from deep half): Elevate their near leg, roll under them
- Dogfight to Back Take: Both have underhooks standing → use forklift, trip, or back take
- Knee Shield Sweep: Knee shield in belly, extend leg while pulling collar

Common Mistakes in Half Guard Sweeps
Losing Hip Position
One of the most common errors is allowing the hips to flatten to the mat, which eliminates frames and makes sweeps ineffective. Keep active hip engagement at all times.
Neglecting Grip Fighting
Grips are the foundation of guard work. Failing to break or establish grips early puts you at a structural disadvantage before any technique begins.
Telegraphing Attacks
Pausing before initiating sweeps or submissions signals your opponent. Combine setups and attacks in smooth, continuous motion.
Ignoring Posture Breaking
Allowing your partner to establish a strong, upright posture neutralizes most guard attacks. Prioritize posture disruption with collar, sleeve, or wrist control.
