Split Squat Pass

What This Is

The split squat pass is a pressure pass used primarily from top half guard or from a kneeling-standing position against an open guard. The top player creates a wide split-leg base — one knee on the mat inside the guard, one foot posted far outside — and uses that wide base to pin the bottom player’s hip while working to pass the trapped leg.

The wide base creates two mechanical advantages. First, it is difficult for the bottom player to create the hip escape needed to recover guard when the top player’s weight is spread across a wide base — there is no direction to escape into. Second, the inside knee can drive against the bottom player’s hip line to prevent the half guard recovery while the top player extracts the trapped leg.

Unlike pure pressure passes that rely on chest weight alone, the split squat uses the geometry of the stance to create pressure from the base up, not just from the top down.

The Invariable in Action

In the split squat pass, the trapped leg is itself the foot that needs clearing. The pass is structured to address this directly — the wide base and downward pressure pin the hip and create the environment to extract the trapped foot. INV-P01 is satisfied progressively: the hip pin removes the bottom player’s ability to reposition the trapping leg, and the leg extraction then clears the foot from the knee line.

After the trapped leg is freed, the top player must commit to the knee line. Wide-base pressure passes can stall at the extraction phase if the top player does not follow through with a forward drive to establish the knee line and consolidate. Extraction without advancement is not a completed pass.

The bottom player in half guard has two primary connections: the trapped leg and the underhook or frame. The split squat pass must break both. Freeing the trapped leg while the bottom player has an active underhook allows them to take the back or re-establish deep half. Both connections must be addressed before the pass is complete.

The split squat’s wide base makes it naturally suited to the pin — the stance already limits the bottom player’s movement. The top player should use the base itself as the pin structure, not just the chest weight. Drive the inside knee into the hip line and maintain the wide base all the way through to side control consolidation.

Setup and Entry

From Top Half Guard

The top player is already in top half guard with one leg trapped between the bottom player’s legs. The split squat entry involves driving the inside knee toward the bottom player’s hip — not the thigh — while planting the outside foot wide, creating the split stance. The torso drops to add chest weight, and the available arm reaches for the underhook on the bottom player’s near side. The wide foot position should be far enough outside that the bottom player cannot easily bridge or hip escape into it.

From Disrupted Open Guard

When a standing-pass attempt has been partially defended and the bottom player has caught one leg, the top player can drop into the split squat position rather than attempting to pull the leg free from standing. Drop the inside knee to the mat on the inside of the guard, plant the outside foot wide, and immediately begin the pressure-pass sequence. This converts a failed standing pass into a controlled pressure pass.

Underhook Priority

When establishing the split squat, securing the near underhook is a high-priority task. The underhook pins the bottom player’s shoulder and prevents the two primary counters: the back-take and the deep half entry. If the underhook is not immediately available, post the far-side hand to prevent the back-take first, then work to achieve the underhook as a secondary objective.

Execution

With the split stance established and the underhook (or shoulder pin) in place, the top player drives their chest weight down and forward through the bottom player’s torso. The goal is to flatten the bottom player — taking away the hip-side orientation that half guard requires. A flat bottom player cannot create the hip escape needed to re-hook or go to deep half.

Once the bottom player is flattened, the top player extracts the trapped leg. Three options are common: push the bottom player’s top knee down with the free hand and step the trapped foot over; use a hip shift to walk the hips away from the trapped leg while maintaining chest pressure; or drive the inside knee between the bottom player’s knees, splitting the guard from the inside out.

Throughout the extraction, maintain chest pressure and the wide base. The moment chest pressure releases, the bottom player regains the hip mobility to re-hook. The extraction happens inside the pressure, not after it stops.

Guard Responses

The bottom player’s primary responses to the split squat pass:

• Re-hook with the free leg: The bottom player uses the free leg to hook the top player’s far leg and attempt a hip lock or back-take entry. Counter: keep the outside foot far enough that the free leg cannot easily hook it. If hooked, flatten first and work to disengage the hook before continuing.
• Frame to create space: The bottom player frames against the top player’s hip or face to create distance for a hip escape. Counter: drop chest weight directly into the frame’s base, not against the frame itself. A frame braced against a hip cannot absorb downward weight — it collapses when the top player drops through it.
• Go to deep half: The bottom player ducks under and takes the deep half position. Counter: the underhook prevents this. If deep half is reached despite the underhook, the top player must extract before continuing the pass.
