The deep half sweep — commonly called the Homer Simpson sweep — is the primary offensive option from deep half guard. From the deep half position (the bottom player’s upper body is under the opponent’s hips, with the near leg captured and both arms threaded under the opponent’s near leg), the bottom player secures an underhook around the opponent’s near hip and rolls the opponent over their own head, landing in mount.
The sweep is named Homer Simpson because of the characteristic motion: the bottom player rolls out from under the opponent like someone rolling out from under a car, coming up on top. The image captures the mechanics — the bottom player uses their body as a fulcrum under the opponent’s hip, and the roll carries the opponent over.
Deep half guard is a specialized position that gives the bottom player significant hip control. The sweep converts that hip control into a roll — the opponent’s weight is loaded over the bottom player’s fulcrum (their shoulder and arm), and the roll topples them over.
INV-07Invariant "Establishing connection is the prerequisite for all control. Where INV-01 describes what sustained connection achieves, INV-07 describes the prior requirement: control cannot begin until connection exists. Distance — whether created by the opponent deliberately or allowed to develop accidentally — returns initiative to the opponent and must be closed before control can be re-established."
Why it works hereIn deep half, the connection is the underhook fully cupping the opponent's near hip — the elbow must clear the far side of the hip, not merely touch it. A shallow arm leaves space between the bottom player's shoulder and the hip socket, and that space lets the opponent post their hand and rebase before the roll engages. Depth converts the underhook from contact into a closed loop around the hip, which is what loads the opponent's weight onto the bottom player's shoulder fulcrum.
See full invariant page → In deep half, connection is the underhook around the hip. The bottom player’s arm must reach deep around the opponent’s near hip — not just touching the hip, but fully cupping it with the elbow on the far side of the hip. A shallow arm that rests near the hip without wrapping it provides no leverage for the roll. The depth of the hip underhook is the structural requirement that makes the sweep work. Insufficient depth produces a push rather than a roll.
The sweep requires established deep half guard. See the Deep Half Guard position page for full entry mechanics. The setup specific to the sweep: the bottom player’s near arm (the arm on the same side as the near leg capture) threads under the opponent’s near thigh and reaches for the far hip or the back of the near hip, creating the hip underhook. The far arm assists in pulling the near leg across the bottom player’s chest. Both legs control the near leg.
