Scorpion Pass

What This Is

The scorpion pass defeats the scorpion guard — a half guard variant where the bottom player’s trapping leg has moved from inside the top player’s thighs to the outside, hooking over the outside of the top player’s near knee. This outside hook changes the sweep geometry: instead of sweeping through the centre (as in standard half guard), the scorpion sweep pulls from the outside, extending the top player’s hip laterally to collapse the base.

The position creates a dilemma for the top player: defend the outside-hook sweep and the bottom player takes the back via the underhook; defend the back take and the outside hook sweep arrives. The pass must address both threats simultaneously by removing the outside hook’s leverage before either threat matures.

The scorpion is a transitional position — the bottom player typically arrives from standard half guard or Z-guard by shifting the trapping leg to the outside. Recognising the shift early gives the top player the widest passing window. Once the outside hook is set and the underhook is established, the scorpion’s dilemma is fully loaded.

The Invariable in Action

The scorpion’s outside hook is an unconventional foot-line position. Standard half guard traps the foot between the thighs; the scorpion puts it outside the knee. This means the standard half guard passing response (driving the knee inward) does not work — the hook is on the outside, so inward knee pressure drives into the hook rather than away from it. The pass must address the outside hook specifically.

The scorpion sweep works by pulling the outside hook outward while the hip extends, collapsing the top player’s base on the hooked side. The sweep is a lateral destabilisation — it does not go through the centre like a standard half guard sweep. The pass must prevent the lateral hip extension that powers the sweep — and the simplest way to prevent it is to remove the outside hook before the extension begins.

The scorpion is an underhook-dependent position. The outside hook provides the leg control, but the underhook provides the upper body connection that converts the hook into a sweep or back take. Denying the underhook — via crossface, whizzer, or elbow control — removes the upper body half of the scorpion’s system even if the outside hook remains.

The Outside Hook Problem

The scorpion’s outside hook presents a specific mechanical challenge: it is on the wrong side for standard half guard passing.

Why Standard Half Guard Passing Fails

In standard half guard, the top player drives the knee inward and forward to extract the leg. Against the scorpion, the hook is on the outside — driving the knee inward does not clear it. The hook simply rides along the outside of the knee as it moves inward. The extraction direction must change.

The Correct Direction

The outside hook wraps over the top player’s knee from outside. To clear it, the knee must move backward (away from the bottom player) or rotate outward (opening the angle the hook wraps around). Either direction takes the knee away from the hook’s wrap geometry. The backward step is the primary clearing action; the outward rotation is the secondary.

Timing

The outside hook is easiest to clear before the bottom player completes the underhook. Once the hook and underhook are both established, clearing the hook while the underhook pulls the top player’s body down becomes a dual problem. Clear the hook early — during the leg shift, before the upper body connection solidifies.

Pass Methods

Knee Backstep and Kick Free

Step the hooked knee backward — away from the bottom player — in a controlled circular step. The outside hook’s wrap angle is calibrated for a forward-facing knee; a backward step takes the knee out of the hook’s plane. As the knee steps back, kick the lower leg free with a sharp extension. The hook slides off the outside of the knee as the leg straightens. Immediately advance to a passing position — the bottom player’s half guard structure is gone once the outside hook is cleared.

Crossface and Hip Drive

Drive a heavy crossface — forearm or shoulder across the bottom player’s jaw — while simultaneously driving the hips forward. The crossface denies the underhook by turning the bottom player flat, and the hip drive changes the knee angle relative to the outside hook. The combination of upper body control (crossface) and lower body angle change (hip drive) clears the scorpion’s two-part structure simultaneously. Once flat, the bottom player’s outside hook loses its sweep angle and becomes a passive wrap that can be peeled or stepped out of.

Whizzer to Flatten

When the bottom player has already established the underhook, counter with a whizzer (overhook) on the underhooking arm. The whizzer drives the bottom player’s shoulder to the mat, flattening them. From the whizzer position, the outside hook remains but the sweep and back-take threats are removed — a flat bottom player with a denied underhook cannot generate the hip extension or the rotation needed for either offence. Strip the hook at leisure and pass.

Leg Pummel to Inside

Rather than stepping backward to clear the hook, pummel the hooked leg inward — driving the knee inside the bottom player’s thigh. This converts the outside hook back to an inside hook position (standard half guard), where standard half guard passing applies. The pummel must be quick — the bottom player will resist the transition because standard half guard gives them less offensive leverage than the scorpion. Once inside, knee cut or split squat pass from the recovered standard half guard.

Guard Responses

Scorpion sweep during the backstep: As the top player steps the knee back, the bottom player accelerates the hip extension to sweep before the hook clears. Counter: the backstep must be fast and committed. A tentative step gives the bottom player time to load the sweep — a sharp, committed step clears the hook before the sweep force arrives.

Back take via underhook as you crossface: The bottom player uses the underhook to rotate behind the top player as the crossface drives forward. Counter: the crossface must turn the head away, not just push forward. Turning the head denies the rotation that the back take requires — the bottom player cannot rotate to face the same direction if their head is turned to face the opposite direction.

Waiter guard transition: The bottom player releases the outside hook and threads the far arm under the top player’s far leg, entering waiter position. Counter: recognise the transition early. The moment the outside hook releases, the scorpion threat is gone — advance immediately with a standard half guard pass before the waiter position establishes.

Kneebar counter: As the top player’s knee slips backward through the hook, the bottom player catches the leg in a kneebar configuration. Counter: keep the knee bent during the backstep. A bent knee is kneebar-resistant; a straightened knee during the extraction is vulnerable. The backstep is a bent-knee step, not a straight-leg extension.

Common Errors

Drilling Notes

Developing Drill

Partner establishes scorpion with outside hook and underhook, passive resistance. Top player drills the knee backstep and kick free — ten reps per side. Focus: is the hook clearing in one motion or requiring multiple attempts? One-motion clearing means the angle is correct.

Proficient Drill

Partner in scorpion with live sweep and back-take attempts. Top player must crossface, deny the underhook, and clear the hook within thirty seconds. Ten rounds. Score: pass = win; sweep or back take = loss.

Advanced Drill

Full live rounds starting from Z-guard. Bottom player transitions to scorpion at will. Top player must recognise the transition and address it before the scorpion loads. Three-minute rounds. This drills recognition speed — the window between Z-guard and loaded scorpion is the highest-percentage passing moment.
