Outside hook half guard pass
Also known as Scorpion Pass — the canonical term used on this site.
Training background: describes the hook configuration
Descriptive — scorpion pass vs an outside hook
Outside hook half guard pass is a descriptive name for the scorpion pass — naming the outside-hook half guard the pass is built to defeat.
Etymology. “Outside hook half guard” names the specific position, where the bottom player’s hook sits outside the passer’s leg; “pass” attaches the objective. The compound describes the problem the scorpion pass solves rather than the scorpion shape itself.
Mechanics. The shift destabilises the bottom player’s hooking structure before the passer settles, so control is taken only after the outside hook is broken off its line; advancing into a live hook instead feeds the elevation the guard wants.
Cross-reference. “Lower leg shift pass” is a sibling alias. Full mechanical coverage on Scorpion Pass.
