What This Is
The D’arce choke is a no-gi arm-in triangle choke applied from the front headlock family of positions. When the opponent posts their near arm inside the front headlock — either to post on the mat or to frame against the attacking player — the posted arm creates the entry path for the D’arce.
The choking arm threads under the near arm and wraps around the neck, locking in a configuration where the opponent’s own arm acts as one side of a triangle against their neck. The finish compresses both carotid arteries by squeezing the two arms together around the neck.
The D’arce is mechanically an arm-in triangle choke applied from outside the opponent’s guard rather than from inside. This positional difference — and the threading direction — is what distinguishes it from a standard arm triangle (kata gatame) applied from side control. Both use the opponent’s arm against their own neck; the D’arce threads from the front headlock position and the arm triangle is applied from the side.
This page covers the no-gi D’arce specifically. The gi version — the brabo choke, which uses the lapel — is not covered on this site.
The Invariable in Action
The D’arce is not a one-sided choke. The opponent’s posted arm is not incidental — it is the other half of the vascular compression. When the choking arm threads under the near arm and around the neck, it closes a loop that puts one side of the neck against the choking arm’s forearm/bicep and the other side against the opponent’s own arm. Squeezing the triangle closes both sides simultaneously.
The moment the choking arm threads completely under the near arm and around the neck, the near arm is locked. It cannot be pulled back because the threading locks the arm’s position. This isolation is what makes the D’arce mechanically reliable — unlike submissions where the opponent can simply remove their arm, the D’arce’s threading prevents this once the lock is complete.
A partial D’arce thread — where the arm is partly under the near arm but has not fully cleared and wrapped around the neck — is not the D’arce. It is an arm that is in a compromised position, vulnerable to being pulled free by the opponent before the lock sets. The thread must complete (arm under, around, and locked at the back of the neck) before any finishing motion begins.
The Grip
The D’arce grip is different from the guillotine grip. The mechanics:
The threading arm: The choking arm goes under the opponent’s near arm (inside-to-outside, entering from the inside of the near arm). The arm continues under and then around the neck — not over. The arm is below the near arm at the entry point and circles around and under the neck to arrive at the back of the neck from the far side.
The finish grip: The choking arm hand reaches the bicep of the opposite arm (the supporting arm). The supporting arm’s hand grips the back of the choking arm’s hand or wrist. This creates a “bike lock” grip — two arms locked together around the triangle of the opponent’s arm and neck.
Alternative grip: Some practitioners use a figure-four grip (each hand gripping the other arm’s forearm). The bike lock grip is generally more effective because it allows the arms to be pulled tighter together.
Thread depth: The threading arm must go deep under the near arm — past the elbow toward the shoulder. A shallow thread (only to the elbow of the near arm) does not create a secure triangle and is more easily escaped.
Head position during threading: The attacking player’s head should stay to the far side of the opponent’s head throughout the threading motion. The threading arm goes under the near arm, and the attacker’s body follows the arm around the far side of the opponent’s neck.
The Finish
The D’arce finish is a squeeze — both arms pulling toward each other while body mechanics amplify the compression:
The squeeze direction: Pull the elbows together — the bike lock grip pulls both arms tightly toward the center. The threaded arm pulls the near arm and neck toward the attacker’s body; the supporting arm provides the counter-force.
Body mechanics: The attacker’s chest rolls forward over the opponent’s head, driving weight through the choke. This is not a passive squeeze — the whole upper body contributes. Rolling the body forward (toward the opponent’s far side) creates a rotational force that tightens the triangle around the neck.
The roll finish: In many D’arce applications, the attacker rolls over the opponent to complete the finish. From the front headlock position, rolling toward the mat while maintaining the grip drives the opponent to their back and completes the compression. This roll is not always necessary but significantly amplifies the choke when it is available.
Common error in finishing: Squeezing without rolling (relying only on arm force). The D’arce is more reliably finished with body rotation than with arm force alone. Add the body roll whenever possible.
Setup and Entry
From the Front Headlock (Near Arm Posted)
The primary and most reliable entry. From the front headlock ground control, the opponent posts their near arm on the mat to create a frame or to post up. The moment the near arm comes forward and inside, the attacking player releases the arm-control grip and shoots the threading arm under the near arm. The near arm posting is both a defensive move by the opponent and a D’arce entry signal for the attacker.
From the Turtle Top
From turtle top, when the opponent’s near arm is extended or posted forward (rather than tucked against the hip), the D’arce threading motion can be executed from the side. This requires the attacking player to move their body to the front-headlock angle to complete the thread.
From Side Control
When the near arm in side control is extended forward or exposed — particularly when the opponent attempts to frame against the attacking player’s hip — the D’arce thread is available from the side control position. This is a secondary entry but important to know.
From the Pinch Headlock
The pinch headlock creates a specific angle for D’arce entry when the opponent drops to their knees to avoid the sumi gaeshi. The forward drop puts the near arm in a D’arce entry position. See: Pinch Headlock.
Position Requirements
- Front Headlock (Ground) — Primary position. Near arm posted creates the entry.
- Turtle Top — Available when near arm is not tucked. Requires repositioning to front headlock angle for the thread.
- Side Control — Available when near arm is exposed forward. Secondary entry path.
- Pinch Headlock — Available when opponent drops forward to avoid the sumi gaeshi.
Defence and Escape
Priority 1 — Do not post the near arm: The D’arce requires the near arm to be inside. The most effective defence is never posting the near arm in the front headlock position. Keep the near arm tucked or controlled — do not post it forward.
Priority 2 — When posting, post wide and immediately recover: If the near arm must post (for a stand-up attempt), post it as briefly as possible and recover the arm quickly. The D’arce window is open only while the arm is inside — recovering the arm closes the window.
Priority 3 — When the thread begins, square up: As the choking arm begins threading under the near arm, the defender must rotate their body to face the attacker (hip movement). Squaring up removes the angle that the D’arce threading requires. A D’arce thread cannot complete when the defender is facing the attacker.
Priority 4 — When the thread completes, roll away: Once the thread is complete and the lock is set, the defender is in a compromised position. The only remaining option is to roll toward the far side (away from the attacker) and accept going to the back, or to tap before the finish completes. Rolling away does not escape the D’arce — it trades position for time. Tap when the compression becomes significant.
No-Gi vs Gi — D’arce vs Brabo
The brabo choke is the gi version of the D’arce. It uses the opponent’s gi lapel threaded under the near arm and around the neck, creating the same triangle compression. The mechanics are similar but the lapel adds a gripping tool that is not available in no-gi.
This site covers no-gi grappling only. The brabo choke is not documented here. If you train in the gi, the brabo uses the same entry read as the D’arce — near arm inside after the thread — but the lapel grip replaces the choking arm’s wrap-around.
Common Errors
Error 1: Shallow thread — only to the near arm’s elbow
Why it fails: A thread that stops at the near elbow does not create a secure triangle. The opponent can pull their elbow back and free the arm before the lock sets. INV-S02 fails.
Correction: Thread past the elbow, as deep as the near arm’s shoulder/armpit. The thread depth determines the security of the lock.
Error 2: Finishing with arm force only, no body roll
Why it fails: Arm force alone is insufficient for most D’arce finishes against a resisting opponent. The body roll amplifies the compression significantly.
Correction: Roll the body forward over the opponent’s head as the squeeze is applied. The roll and the squeeze are simultaneous — not sequential.
Error 3: Losing the thread when the opponent turns to face the attacker
Why it fails: When the opponent squares up during the threading motion, the thread cannot complete — but if the attacker commits without recognising this, they end up in a compromised arm position.
Correction: If the opponent squares up during threading, abort the D’arce and reassess. The entry window is positional — it only works when the opponent’s near arm is inside. If they square up, the entry has closed.
Drilling Notes
Proficient Drilling
Drill the threading motion in isolation: partner in front headlock position with near arm posted, attacker drills the threading motion from start to finish. The thread must go under the near arm, around the neck, and lock at the back of the neck. Practice until the path is automatic.
Finish Drilling
From a static locked D’arce position, drill the finish: bike lock grip set, body roll forward, squeeze. Feel the bilateral compression. The body roll should be part of the finish drill from the beginning — not added later.
Entry + Finish Chain
Drill the complete chain: front headlock → near arm posted → threading motion → lock → roll and squeeze. This chain should eventually be practiced against light resistance — the threading motion is what most people lose at the entry stage when the opponent moves.
Ability Level Guidance
Proficient
Learn the threading motion in detail — the path, the depth, and the lock point. This is a technique where the entry mechanics are more complex than the finish. Understand the D’arce entry as a read: near arm inside = D’arce entry open. This read should be reflexive.
Advanced
Use the D’arce threat to force the opponent to keep their near arm tucked. A tucked near arm opens the back take. A posted near arm opens the D’arce. This reciprocal threat relationship is the advanced front headlock D’arce game.
Ruleset Context
The D’arce choke is unrestricted in all standard no-gi rulesets.
