Arm-in Guillotine Arm In Guillotine

The Arm-In Guillotine is a powerful variation of the classic Guillotine Choke in Brazilian Jiu-Jitsu, characterized by trapping one of the opponent's arms alongside their neck. This head-and-arm configuration provides superior control over the opponent's upper body compared to the standard guillotine, which targets only the neck. Historically, the Arm-In Guillotine rose to prominence in the late 1990s through the innovations of Renzo Gracie, who refined and popularized the technique by successfully submitting elite-level opponents. Often referred to as the "Renzo Guillotine" or "Renzo's Trick," this choke has since become a high-percentage submission in both Brazilian Jiu-Jitsu and Mixed Martial Arts (MMA).

The Arm-In Guillotine primarily functions as a blood choke, compressing the carotid arteries on both sides of the opponent's neck. Mechanically similar to other head-and-arm chokes, such as the Arm Triangle Choke, it utilizes the opponent's trapped shoulder and arm to occlude one side of their neck, while the attacker's choking arm applies pressure on the opposite side. The choking arm wraps deeply around the opponent's neck, with the forearm positioned snugly beneath the chin. Common grips include the palm-to-palm gable grip or an over-hand wrist grip. Proper execution involves applying inward and upward pressure with the forearm and bicep, combined with the opponent's own shoulder pressing into their neck. Misalignment can lead to a partial air choke or neck crank, underscoring the importance of precise positioning.

The Arm-In Guillotine is frequently initiated from the front headlock position, often beginning with a "chin strap" grip, where the attacker cups the opponent's chin for head control. It is commonly employed as a counter to wrestling shots, such as double-leg or single-leg takedowns, and during scrambles where the opponent's head and arm become exposed. Practitioners regularly apply the Arm-In Guillotine from closed guard, turtle position, or even standing scenarios, capitalizing on compromised posture and exposed neck opportunities.

1. Secure a deep choking arm placement, ensuring the wrist or forearm is firmly positioned beneath the opponent's chin.
2. Lock your hands securely using a palm-to-palm gable grip or an over-hand wrist grip.
3. Close your guard tightly around the opponent's torso, pulling them inward to eliminate space and prevent escapes.
4. Slightly elevate your hips while performing a controlled crunching motion, driving the opponent's head downward into the choke.
5. Pinch your elbows inward or flare the choking elbow slightly upward to remove slack and intensify the choke.

When executed correctly, the Arm-In Guillotine creates a vise-like constriction, rapidly inducing submission or unconsciousness.

Shallow Grip and Poor Hand Placement

Failing to wrap the choking arm deeply beneath the chin allows the opponent's head to slip out easily.

Failure to Angle Hips

Remaining flat on your back without angling hips toward the trapped-arm side significantly reduces choke effectiveness.

Over-Arching or Excessive Bridging

Exaggerated bridging can inadvertently relieve pressure, creating space for the opponent to escape.

Extending Legs and Pushing Opponent Away

Straightening your legs or pushing outward loosens the guard, diminishing choke pressure.

Holding Choke After Opponent Passes to Side Control

Persisting with the choke after the opponent moves to side control risks exposure to counter-submissions like the Von Flue Choke.

Early Hand-Fighting and Chin Tuck

Immediately grip the attacker's wrist or forearm and tuck your chin to prevent full choke application.

Passing to the Safe Side

Move toward the side opposite the choking arm, aiming to achieve side control and relieve choke pressure.

Von Flue Choke Counter

If the attacker maintains the guillotine after you've established side control, apply the Von Flue Choke by driving shoulder pressure into their neck.

Posturing Up and Peeling Grips

From closed guard, posture upward and methodically peel apart the attacker's grip to escape.

The Arm-In Guillotine serves both offensive and reactive purposes in competition and MMA. Offensively, practitioners utilize it as a planned attack from closed guard or front headlock positions. Reactively, it is an effective counter to takedown attempts and scrambles. The technique provides significant control, enabling practitioners to advance position or transition seamlessly to other submissions such as the Darce Choke, Anaconda Choke, or Arm Triangle Choke. Its adaptability in dynamic transitions and scrambles makes the Arm-In Guillotine a versatile and essential submission in modern Brazilian Jiu-Jitsu and submission grappling.
