Half guard knee hook sweep

Half guard knee hook sweep is a descriptive name for the scorpion sweep — naming the knee hook on the opponent’s leg that drives the reversal.

Etymology. “Knee hook” describes the bottom player’s leg hooking behind the opponent’s knee; “half guard sweep” names the context and action. The label foregrounds the hooking leg that the scorpion shape creates.

Mechanics. The knee hook is the connection that creates the offensive opening: hooking behind the opponent’s knee gives the bottom player a handle on that leg, and combined with a hand post, it lets them off-balance and steer the leg out from under the opponent into the sweep.

Cross-reference. “Scorpion position sweep” is a sibling alias. Full mechanical coverage on Scorpion Sweep.
