Basic half guard sweep

Basic half guard sweep is a descriptive name for the lower leg shift sweep — “basic” marking it as the foundational sweep of half guard.

Etymology. “Basic” frames it as the first half-guard sweep taught; “half guard sweep” names the action. The label is plain and lineage-neutral, distinguishing the core reversal from its variations.

Mechanics. The half guard sweep turns on the underhook: winning the underhook controls the near hip, and from there the bottom player drives into the opponent’s base while the lower leg lifts, reversing toward the side where the hip is owned. Losing the underhook hands that hip — and the top position — back.

Cross-reference. “Lower leg sweep,” “Hip dump sweep,” and “Knee shield sweep” are sibling aliases. Full mechanical coverage on Lower Leg Shift Sweep.
