Defending the Rear Naked Choke Setup is the most critical defensive skill in Brazilian Jiu-Jitsu, as the RNC is the highest-percentage finish from the most dominant position. As the defender, your situation is precarious but far from hopeless—the attacker must complete a multi-step sequence of grip stripping, angle creation, arm insertion, and grip locking before the choke threatens consciousness. Each step in that sequence represents a defensive window you can exploit. Your goal is not necessarily to escape back control entirely during this phase, but to prevent the choke from being established while working toward positional improvements.
Defensive success requires understanding the attacker’s sequence and disrupting it at the earliest possible point. The highest-percentage defensive window is during the grip-stripping phase, where maintaining two-on-one control of the choking arm prevents the entire sequence from progressing. If the attacker clears your grip defense, the next critical moment is during arm insertion—chin tuck and shoulder elevation create physical barriers that block the forearm from reaching the carotid arteries. Once the arm is beneath your chin, your options narrow dramatically, making early-phase defense essential.
Strategically, your defensive priorities follow a strict hierarchy: protect the neck first, maintain hand fighting control second, work to disrupt the attacker’s positional base third, and pursue escape opportunities fourth. Violating this hierarchy—for example, fighting hooks before defending the neck—consistently results in submission. Effective defenders combine stubborn grip fighting with calculated escape timing, recognizing that the attacker’s commitment to the choke sequence creates momentary positional vulnerabilities you can exploit for escape to turtle, half guard, or standing positions.
Opponent’s Starting Position: Back Control (Top)
How to Recognize This Attack
- Attacker releases their clasped seatbelt grip and begins isolating your defending hand with their non-choking arm, indicating they are transitioning from control to active choke setup
- You feel the attacker’s hips shift to one side while their chest pressure increases on the opposite shoulder, signaling an angle change designed to expose your neck on the choking side
- The attacker’s choking-side forearm begins sliding along your collarbone or jaw line rather than maintaining the static over-shoulder harness position, indicating imminent arm insertion attempt
- Attacker uses their hook or leg to trap your defending arm against your body, removing your hand from the neck defense equation before attempting insertion
- You feel increased forward head pressure from the attacker combined with their free hand cupping your forehead or pushing your chin upward, indicating they are creating space for the choking arm to slide beneath
Key Defensive Principles
- Two-on-one control of the choking arm is your primary defense—never voluntarily release this grip to address secondary threats like hooks
- Tuck your chin tightly to your chest and raise your shoulder on the choking side to create a physical barrier against arm insertion
- Fight the hands before fighting the position—neutralizing the choke threat buys time for positional escapes
- Turn toward the underhook side when creating escape angles, as this disrupts the attacker’s alignment and opens hip escape pathways
- Monitor the attacker’s weight distribution through tactile awareness—shifts in pressure signal transitions between grip stripping and arm insertion
- Maintain controlled breathing and avoid panic—frantic movements burn energy and create openings the attacker exploits for arm insertion
Defensive Options
1. Establish and maintain two-on-one grip control on the choking arm, gripping the wrist with one hand and the forearm or tricep with the other, pulling the arm down toward your chest while tucking your chin
- When to use: Immediately when you recognize the attacker is transitioning from harness control to active choke setup—this is your first and highest-priority defense
- Targets: Back Control
- If successful: The choke sequence stalls completely and the attacker must restart the grip-stripping process, keeping you in back control without immediate submission threat
- Risk: If the attacker strips your two-on-one using their free hand, you may be momentarily defenseless during the re-grip attempt
2. Hip escape toward the underhook side while maintaining chin tuck and hand fighting, sliding your hips away to create an angle that disrupts the attacker’s chest-to-back connection
- When to use: When the attacker commits both hands to the choke setup and momentarily loosens their hook pressure or body triangle control during the insertion attempt
- Targets: Turtle
- If successful: You create enough angle to turn into the attacker and recover to turtle position, escaping the immediate choke threat and resetting to a more defensible position
- Risk: If the attacker follows your hip movement while maintaining the choking arm position, you may end up in a worse angle with the neck more exposed
3. Bridge explosively toward the choking side and rotate your body to face the attacker, driving your near shoulder into their chest while clearing the bottom hook
- When to use: When the attacker’s arm is partially inserted but not yet locked in figure-four—this is your last high-percentage window before the choke is secured
- Targets: Turtle
- If successful: You turn to face the attacker and recover to turtle or half guard, with the partially inserted choking arm now in a much weaker position that can be stripped during the transition
- Risk: If the bridge lacks sufficient explosiveness, the attacker follows your rotation and maintains back control with the choking arm now deeper than before
4. Strip the attacker’s non-choking hand from behind your head before they complete the figure-four lock, grabbing their wrist and pulling it forward over your shoulder
- When to use: When the choking arm is already beneath your chin but the attacker has not yet placed their hand behind your head to complete the figure-four grip
- Targets: Back Control
- If successful: Without the figure-four lock, the choke lacks the mechanical structure to finish effectively, buying significant time for continued defense and escape attempts
- Risk: Focusing on the non-choking hand may cause you to release control of the choking arm, allowing the attacker to deepen their position
Best-Case Outcomes for Defender
→ Back Control
Maintain relentless two-on-one grip fighting on the choking arm, preventing the attacker from ever inserting it beneath your chin. Combined with chin tuck and shoulder elevation, this stalls the setup indefinitely and forces the attacker to either abandon the RNC attempt or continue burning energy in grip fights. The attacker remains in back control but without submission threat, giving you time to work systematic escape sequences.
→ Turtle
Time your hip escape for the moment the attacker commits both hands to the choke insertion, momentarily reducing their hook or body control pressure. Execute an explosive hip escape toward the underhook side while maintaining your grip on the choking arm, creating enough angle to turn your body and recover to turtle position. From turtle, you have significantly better escape options including granby rolls, sit-outs, and stand-up sequences.
Test Your Knowledge
Q1: What is the single most important defensive grip when your opponent initiates the RNC setup sequence? A: Two-on-one control on the choking arm is the most important defensive grip. One hand grips the attacker’s wrist while the other controls their forearm or tricep, pulling the entire arm down toward your chest. This grip prevents the choking arm from reaching your neck at all, stalling the entire setup sequence at its earliest and most defensible phase. A single grip on the wrist alone is insufficient because the attacker can strip it with their free hand.
Q2: Your opponent strips your top grip on their choking arm and begins sliding it toward your chin—what is your immediate response? A: Immediately increase your chin tuck by driving your chin hard into your chest while simultaneously raising your shoulder on the choking side to create a physical wall. Use your remaining grip on their wrist to pull the arm down and away from your neck. With your freed hand, re-establish the two-on-one by gripping their forearm above your existing wrist grip. Do not attempt an escape at this moment—focus entirely on re-establishing hand control before the arm gets beneath your chin.
Q3: Why should you turn toward the underhook side rather than the overhook side when attempting to escape during the RNC setup? A: Turning toward the underhook side disrupts the attacker’s structural alignment because it compresses the space on the choking side where they need room for arm insertion. It also positions your shoulder as a barrier against the choking arm and creates the optimal angle for hip escape to turtle. Turning toward the overhook side opens the neck on the choking side, plays into the attacker’s angle change, and makes arm insertion significantly easier.
Q4: The attacker has their arm beneath your chin but has not locked the figure-four—what can you still do? A: This is your last high-percentage defensive window. Target the non-choking hand before it reaches behind your head to complete the figure-four. Grab their wrist and pull it forward over your shoulder, preventing the lock. Simultaneously work to pull the choking arm wrist down and forward to reduce the depth of their forearm across your neck. You can also attempt an explosive bridge and rotation toward the choking arm side to dislodge the partially set arm during the transition. Without the figure-four completed, the choke lacks full mechanical advantage.
Q5: When is the optimal moment to attempt a positional escape during your opponent’s RNC setup sequence? A: The optimal escape window opens when the attacker commits both hands to the choke insertion sequence, which momentarily reduces their hook or body control pressure. Watch for the moment they release their clasped seatbelt grip to begin stripping your defenses—this is when their positional control is weakest because their hands are occupied with your arms rather than controlling your body. Time your hip escape for this transition point, maintaining your grip on the choking arm throughout the escape movement.
