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 passes across the front of the throat to the far side of the neck, where the hand grips the attacker’s own far bicep and the lock closes beside the neck. The opponent’s own arm acts as one side of a triangle against their neck. The finish compresses both carotid arteries by squeezing the elbows together while the chest drives down over the opponent’s head and shoulder.

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.

In no-gi usage, “brabo choke” is a common synonym for the D’arce; the name also historically attaches to a gi lapel variation.

INV-S01Invariant "All strangles require compression on both sides of the neck simultaneously. Compression on one side only creates discomfort; compression on both sides interrupts blood flow."

Why it works hereThe D'arce closes a triangle around the neck where the choking arm's bicep loads one carotid and the opponent's own near-side shoulder/upper arm loads the other. Without the threaded near arm pressing into its own carotid, only the choking arm makes contact and the squeeze becomes a one-sided neck crank. The bilateral mechanism is precisely why the thread depth matters: the opponent's arm has to be pinned tight against their own neck before any squeeze begins.

See full invariant page → The opponent’s posted arm is the other half of the vascular compression. When the choking arm threads under the near arm and crosses the front of 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.
