Why Half Guard Is One of the Best Guards in BJJ
Half guard is often dismissed as an "accidental" guard β something you land in when a full guard pass fails. In reality, half guard is a sophisticated, high-percentage guard with its own complete sweep and submission system. Many elite competitors build their entire game around it.
Half Guard Variants
| Variant | Position | Primary Goal |
|---|---|---|
| Basic Half Guard | Knee shield + frame | Prevent pass, recover guard |
| Underhook Half Guard | Deep underhook on far side | Come to knees / single leg / back |
| Deep Half Guard | Head under their thigh, arm around far leg | High-percentage sweeps |
| Lockdown Half Guard | Figure-4 on their leg (lockdown) | Control, whip-ups, electric chair |
| Z-Guard (Knee Shield) | Knee as a frame against their hip | Keep distance, recover open guard |
