Z-guard half

Z-guard half is the full descriptive name for the Z-guard — flagging both the Z-shape leg-geometry and the half-guard position-family in a single compound label.

Etymology. “Z-guard” specifies the leg-geometry; “half” attaches the broader position-family context. The full form predominates in instructional material that needs to disambiguate from other Z-shape configurations.

Mechanics. The Z-shape geometry combines a shielding knee with half-guard leg control — the bottom player has both chest-protection and pass-prevention from the same structural configuration.

Cross-reference. “Knee shield half guard,” “Z-half,” and “high guard half” are alternate names. Full mechanical coverage on Z Guard.
