Half-guard shield break
Also known as Knee Shield Break — the canonical term used on this site.
Training background: when the shield is within a half guard
Descriptive — breaking the shield in half guard
Half-guard shield break is a descriptive name for the knee shield break — locating the knee shield within half guard, where the framing shin most often appears.
Etymology. “Half-guard shield” situates the knee shield in its usual context, a half-guard variant; “break” attaches the objective. The compound is descriptive and lineage-neutral, naming both the position and the action.
Mechanics. The braced shin is the foot-line barrier of this guard; clearing it is the foot-clearance that must precede the pass, since advancing into an active knee shield walks the passer onto the frame rather than around it.
Cross-reference. “Z-guard break,” “Shield pass,” and “Knee shield neutralisation” are sibling aliases. Full mechanical coverage on Knee Shield Break.
