The Switch to Darce Configuration is a grip transition from the Buggy Choke top position that capitalizes on the opponent turning into the attack. When the opponent rotates toward the choking arm to relieve collar pressure, they expose the armpit-to-neck channel that enables the darce choke. Rather than maintaining the original buggy choke angle, the top player withdraws the threading arm from the collar and reroutes it through the gap between the opponent’s neck and far arm, threading under the far armpit and around the back of the neck to lock a figure-four grip from the opposite direction compared to the anaconda.
The darce configuration is mechanically distinct from the anaconda because the choking arm enters under the opponent’s far armpit first and then wraps around the neck, whereas the anaconda wraps the neck first and connects under the armpit. This threading direction means the darce is favored when the opponent’s far arm is elevated or posted wide, creating space under the armpit for arm insertion. The buggy choke position is an ideal launching pad because the original threading arm is already operating in the near-armpit channel and can be redirected through the neck-armpit corridor with minimal repositioning.
This transition is a critical branch in the buggy choke attack tree. Opponents who turn in to defend the collar grip inadvertently create the head-and-arm angle required for both darce and anaconda attacks. Choosing the darce over the anaconda depends on arm positioning and the specific angle of the opponent’s rotation. The darce configuration offers a powerful finishing position because the choking arm’s blade sits directly across the carotid with the opponent’s own trapped shoulder acting as the secondary compression point. Once the figure-four locks, the top player sprawls and walks hips toward the head to generate finishing pressure through body mechanics rather than arm strength.

Key Attacking Principles
- Read the opponent’s rotation toward the choking arm as the trigger to initiate the darce switch rather than forcing the original buggy choke angle
- Withdraw the threading arm from the collar and redirect it through the gap between the opponent’s neck and far arm in one continuous motion
- Thread the choking arm under the opponent’s far armpit first, then wrap around the back of the neck to establish the darce arm path
- Lock the figure-four grip with the choking arm’s hand gripping your own bicep and the support arm’s hand pressing the opponent’s head or trapped shoulder down
- Maintain constant chest-to-back pressure throughout the grip transition to prevent the opponent from posturing, re-turtling, or pulling guard
- Sprawl and walk hips toward the opponent’s head to generate finishing pressure through body angle rather than arm squeezing
- Prioritize threading depth over speed—a shallow darce grip that does not fully encircle the neck-armpit channel will not generate bilateral carotid compression
Prerequisites
- Buggy Choke top control is established with threading arm under opponent’s near armpit and at least partial collar or neck access
- Opponent has begun rotating or turning toward the choking arm, exposing the far armpit and neck channel for darce arm threading
- Top player maintains chest-to-back pressure and hip weight sufficient to prevent opponent from standing or pulling guard during grip transition
- Opponent’s far arm is elevated, posted, or separated from their body enough to allow threading under the far armpit
- The opponent’s near arm is positioned such that the darce threading path between neck and far arm is open for arm insertion
Execution Steps
- Recognize rotation trigger: Feel the opponent begin rotating their torso toward your choking arm to relieve collar pressure. Their near shoulder rises and far shoulder drops, creating the head-and-arm channel. Simultaneously assess whether the far armpit is accessible for darce threading—if the far arm is posted or elevated, the darce angle is mechanically favored over the anaconda.
- Release collar and redirect arm path: Release the far-side collar grip with your threading arm and begin redirecting it from the near-armpit channel toward the gap between the opponent’s neck and far arm. The hand withdraws from the collar and travels across the opponent’s upper back toward the far side, maintaining contact with their body throughout to prevent space creation.
- Thread under far armpit: Drive your choking arm under the opponent’s far armpit from the back side, threading deep enough that your forearm emerges on the other side of their neck with the blade of your wrist settling against the near-side carotid artery. The palm should face down as you thread, allowing the forearm to seat across the throat once the arm is fully through the neck-armpit channel.
- Secure opponent’s head position: Use your support arm (the arm that was not threading) to cup the back of the opponent’s head or press their trapped shoulder down, preventing them from posturing up or extracting their head from the darce channel. The opponent’s near arm should be trapped between their own head and your choking arm, acting as the compression fulcrum.
- Lock figure-four grip: Connect the figure-four by gripping your own bicep with the choking arm’s hand while the support arm’s hand presses the back of the opponent’s head or their trapped shoulder firmly downward. Squeeze your elbows together to eliminate slack in the grip structure and begin applying bilateral carotid compression through the forearm-and-shoulder mechanics.
- Consolidate darce control position: Walk your hips toward the opponent’s head and sprawl your legs back to create a perpendicular angle between your body and theirs. Drop your weight low against the mat and let gravity drive the compression downward through the figure-four structure. The opponent’s own trapped shoulder provides the secondary compression point against the opposite carotid.
- Apply finishing pressure or transition: Squeeze your elbows together while maintaining the sprawl and hip angle to finish the darce choke. If the opponent defends by rolling to their back, follow them and maintain the grip—the darce finishes effectively from this angle as well. If the grip is not deep enough to finish, maintain darce control and work to improve arm depth before re-attempting the squeeze.

Opponent Counters
- Opponent tucks chin hard and clamps far elbow tight to ribs, denying the armpit threading path during the redirect phase (Effectiveness: High) - Your Response: If the far armpit is blocked, abandon the darce switch and either return to the original buggy choke collar grip or switch to the anaconda configuration which threads around the neck first and does not require far armpit access → Leads to Buggy Choke
- Opponent extracts their near arm from the trapped position before the figure-four grip is secured, eliminating the compression fulcrum (Effectiveness: High) - Your Response: Without the trapped arm, switch to a guillotine configuration since you already have neck access, or disengage the neck and transition to back control by hooking the near leg as they posture to escape → Leads to Buggy Choke
- Opponent sits to guard explosively during the grip transition window when control is momentarily loosened (Effectiveness: Medium) - Your Response: Follow the sitting motion and use the partial neck wrap to establish a front headlock or arm-in guillotine from the new angle. Maintain head control throughout the transition to prevent full guard recovery → Leads to Half Guard
- Opponent drives forward aggressively and re-turtles tightly, collapsing the space needed for the darce arm to thread (Effectiveness: Medium) - Your Response: Use a snapdown to break their forward drive and re-expose the neck. If they maintain a tight turtle, reset to buggy choke control and wait for the next rotation trigger before reattempting → Leads to Buggy Choke
Test Your Knowledge
Q1: What is the primary trigger that signals the correct timing to switch from buggy choke to darce configuration? A: The primary trigger is the opponent rotating their torso toward your choking arm to relieve collar pressure. Their near shoulder rises and far shoulder drops, exposing the armpit-to-neck channel. Simultaneously, the far arm must be posted or elevated enough to allow arm threading under the far armpit. This rotation creates the mechanical angle that makes the darce viable while weakening the original buggy choke.
Q2: What is the critical mechanical difference between when to choose the darce switch versus the anaconda switch from buggy choke top? A: The darce threads under the opponent’s far armpit first and then wraps around the neck, while the anaconda wraps the neck first and connects under the armpit. Choose the darce when the opponent’s far arm is elevated or posted wide, creating space under the armpit. Choose the anaconda when the near arm is tightly trapped between the opponent’s head and your body and the far armpit is closed. The threading direction determines which choke is mechanically available.
Q3: Your opponent clamps their far elbow tight to their ribs as you attempt to thread under the far armpit—how do you adjust? A: Abandon the darce angle because the threading path is blocked. Immediately switch to the anaconda configuration, which wraps the neck first and does not require far armpit access. Alternatively, return to the original buggy choke collar grip and wait for the opponent to react again, then read whether the next defensive motion opens the darce or anaconda path.
Q4: Why must the choking arm thread under the far armpit with sufficient depth before locking the figure-four? A: Insufficient threading depth means the forearm blade does not seat fully across the throat against the near-side carotid artery. A shallow darce creates a loose grip where the opponent can posture up, create space between your forearm and their neck, or strip the grip entirely. Deep threading ensures the wrist bone and forearm blade create a tight seal across the carotid that cannot be relieved by head movement or posture changes.
Q5: What role does the opponent’s trapped near arm play in the darce choke mechanics? A: The trapped near arm acts as a compression fulcrum. The choking arm compresses one carotid from the front, while the opponent’s own trapped shoulder drives into the opposite carotid as the figure-four tightens. Without this trapped arm, the darce becomes a one-sided neck pressure that is far easier to defend and significantly less likely to produce a tap from bilateral blood restriction.
Q6: How do you generate finishing pressure in the darce without relying on arm strength alone? A: Walk your hips toward the opponent’s head while sprawling your legs back to create a perpendicular angle between your body and theirs. This uses body weight and gravity to drive the figure-four compression downward through the grip structure. The elbows squeeze together to eliminate slack, but the actual finishing force comes from the sprawl pressure and hip angle, not from bicep squeezing. This makes the choke sustainable and mechanically efficient.
Q7: Your opponent begins sitting to guard explosively as you release the buggy choke collar to initiate the darce switch—what is your response? A: Follow the sitting motion and use whatever neck contact you have to establish a front headlock or arm-in guillotine from the new angle. The opponent’s explosive sit creates forward momentum you can redirect into a snapdown. If they achieve full closed guard before you can secure head control, consolidate top position inside their guard and reset. Do not chase the darce from inside closed guard.
Q8: What are the entry requirements that must exist before attempting the darce switch from buggy choke top? A: Four conditions must be present: buggy choke top control with at least partial collar or neck access, opponent rotation toward the choking arm exposing the far side, far arm posted or elevated enough to allow threading under the armpit, and sufficient chest-to-back pressure maintained to prevent the opponent from escaping during the grip transition window. Missing any one of these conditions significantly reduces success probability.
Q9: Why should the collar release and darce arm redirect be executed as one continuous motion rather than in separate steps? A: Any pause between releasing the collar and threading under the far armpit creates a defensive window where the opponent can re-turtle tightly, clamp the far elbow to their ribs, strip remaining grips, or sit to guard. The continuous motion ensures the opponent’s reaction to losing collar pressure flows directly into the new threading path before they can process the grip change and implement specific darce defense.
Q10: If your darce grip is locked but the opponent rolls to their back to defend the top sprawl finish, what adjustment do you make? A: Follow the roll and maintain the darce grip throughout. The darce finishes effectively from the chest-to-chest position with the opponent on their back, and in some cases the finishing angle improves because gravity assists the compression. Walk your hips to maintain perpendicular pressure and continue squeezing. Do not release the grip to chase a top position—the darce is viable from multiple angles once the figure-four is fully locked.
Safety Considerations
The darce choke is a blood choke that compresses both carotid arteries simultaneously, producing unconsciousness within seconds when properly applied. Always apply the grip progressively during training and allow adequate time for your partner to recognize the pressure and tap before the choke fully engages. The arm threading under the far armpit can strain the opponent’s shoulder if forced aggressively, so thread smoothly rather than yanking. Partners should tap early when bilateral pressure is felt rather than waiting for vision changes. Practitioners with cervical spine issues should communicate this before drilling, as the head pressure component can aggravate existing neck conditions. Never apply cranking or twisting force—the darce is a squeeze, not a crank. Release immediately upon tap and monitor your partner for delayed symptoms after successful applications.
