Rear Naked Choke from Crucifix

SAFETY: Rear Naked Choke from Crucifix targets the Carotid arteries and jugular veins. Risk: Loss of consciousness from blood choke. Release immediately upon tap.

Play as Attacker Play as Defender

The Rear Naked Choke from Crucifix exploits the defining advantage of the crucifix position: complete bilateral arm isolation. With both of the opponent’s arms trapped—one by a leg triangle configuration and the other by hand or overhook control—the neck becomes almost entirely undefended, creating a finishing scenario with one of the highest success rates of any choke setup in competitive grappling.

The primary technical challenge lies in transitioning from arm control to choking grip without compromising positional integrity. The attacker must release control of the far arm to thread the choking arm under the opponent’s chin, creating a brief vulnerability window where the defender may free a hand for neck defense. Timing this transition—and having secondary controls ready—separates successful finishes from scrambles back to neutral crucifix.

Unlike the standard RNC from back control, the crucifix variant benefits from the opponent’s severely limited hip mobility and inability to create defensive angles. The trapped arms cannot generate the frames needed for escape, and the opponent’s awareness of their vulnerability often produces reactions that further expose the neck. Advanced practitioners use the choke threat to set up arm attacks, creating a submission chain where defending one threat opens another.

Safety Guide

Injury Risks:

Injury	Severity	Recovery Time
Loss of consciousness from blood choke	High	Immediate to 30 seconds with proper release
Trachea damage from improper forearm placement	CRITICAL	2-6 weeks, potential permanent damage
Neck strain or muscle damage	Medium	3-7 days
Carotid artery injury from excessive force	CRITICAL	Immediate medical attention required

Application Speed: SLOW and progressive - 3-5 seconds minimum in training. Never snap or jerk the choke. Partner should have full awareness of pressure building.

Tap Signals:

• Verbal tap (say ‘tap’ or make any verbal sound)
• Physical hand tap on opponent’s body or mat
• Physical foot tap on mat
• Going limp or loss of consciousness
• Any distress signal or unusual sound

Release Protocol:

1. Immediately release choking arm upon tap signal
2. Remove hooks and leg triangle trapping the arm
3. Gently guide partner to side-lying recovery position
4. Monitor consciousness and breathing for 30 seconds
5. If partner was unconscious, keep them lying down until fully alert
6. Never allow unconscious partner to stand immediately

Training Restrictions:

• Never use competition speed or intensity in drilling
• Never apply the choke to the trachea or windpipe
• Always ensure partner has clear tap access with at least one hand
• Stop immediately if partner makes any distress sound
• Never hold a choke past the tap for any reason
• Beginners must practice with extremely slow progression only

Key Principles

• Maintain leg triangle pressure on the trapped arm throughout the entire choke sequence—this is your positional anchor that makes the finish possible

• Minimize the transition window when releasing the far arm to thread the choking arm—pre-position the choking arm close to the neck before releasing

• Thread the choking arm palm-down along the jawline, using the chin as a guide rather than forcing under it

• Secure the figure-four lock behind the head, not behind the neck, and press the head forward to prevent chin tuck defense

• Apply squeeze through shoulder retraction and chest expansion rather than bicep flexion for deeper, more efficient carotid compression

• Keep your head tight against the opponent’s temple to prevent them from turning into the choke and creating defensive space

Execution Steps

• Confirm Crucifix Integrity: Verify that the leg triangle is locked tight on the near arm with constant inward pressure. Test by …

• Secure Far Arm and Assess Neck Access: Control the opponent’s far arm with a strong wrist grip or deep overhook. Use this moment to assess …

• Release Far Arm and Thread Choking Arm: This is the critical transition moment. Release control of the far arm and immediately drive your ch…

• Slide Forearm Under the Chin: Guide your forearm under the chin by using the blade of your wrist against the jawline as a wedge. K…

• Lock the Figure-Four Behind the Head: Bring your non-choking hand to grip your own bicep on the choking arm, forming the classic figure-fo…

• Apply Controlled Squeeze and Finish: Squeeze by retracting your shoulders and expanding your chest rather than flexing your bicep. Keep y…

Common Mistakes

• Releasing far arm control before the choking arm is pre-positioned near the neck

  • Consequence: Gives the opponent a free hand for neck defense well before the choke is in position, converting a dominant position into a contested scramble
  • Correction: Pre-position the choking arm close to the neck before releasing the far arm. The release and thread should be nearly simultaneous with minimal gap between them.

• Placing the forearm across the trachea instead of the carotid arteries

  • Consequence: Creates a windpipe crush that is painful but does not produce a blood choke, giving the opponent more time to escape and risking serious tracheal injury
  • Correction: Align the crook of the elbow with the center of the throat so the radius and ulna compress the carotid arteries on each side. Adjust angle by sliding the arm deeper if the pressure is on the front of the throat.

• Loosening the leg triangle while focusing attention on the choke

  • Consequence: Opponent extracts their trapped arm and regains defensive capability, turning a dominant finishing position into a back control scramble
  • Correction: Maintain constant inward squeeze with legs throughout the entire choke sequence. The leg triangle is your positional foundation—never sacrifice it for the choke.

Playing as Defender

→ Full Defender Guide

Key Principles

• Recognize the choke transition immediately—when the attacker releases your far arm, they are committing to the RNC and you must react within 1-2 seconds

• Rush your freed hand to your neck the instant it is released, creating a barrier before the choking arm threads under your chin

• Tuck your chin hard against your chest and raise your shoulder on the threatened side to create a physical barrier against forearm entry

• Work to free the trapped arm from the leg triangle using hip movement and angle changes—a freed arm transforms your defensive options entirely

• Maintain calm breathing and controlled defensive movements rather than explosive panic reactions that waste energy and tighten the position

• If the choke locks fully with the figure-four secured, tap immediately rather than fighting a submission that has virtually zero escape rate from this position

Recognition Cues

• Attacker shifts their hand positioning on your far arm, loosening the wrist grip or overhook in preparation for releasing it to thread the choke

• Attacker adjusts their body angle to align their choking arm with your neck, often bringing their chest and head closer to your temple

• Weight distribution changes as the attacker prepares to commit their arm to the choke, often becoming heavier on one side of your upper body

• You feel the far arm control loosen or disappear entirely, immediately signaling that the choke transition has begun and your defensive window is open

Escape Paths

• Bridge and turn during choke transition window to disrupt crucifix and recover guard position

• Extract trapped arm through incremental hip movement and convert to standard back control escape sequence

• Two-on-one grip fight the choking arm while simultaneously working to free legs from crucifix configuration

Variations

Palm-to-Palm RNC Grip: Instead of the classic figure-four behind the head, clasp both hands together palm-to-palm with the choking forearm under the chin. This grip is faster to secure when the defender gets a hand to their neck, as you can lock the grip around the defensive hand and still generate sufficient carotid compression. (When to use: When the defender manages to get their freed hand to their neck before you can lock the figure-four, trapping the defensive hand inside the choke)

Over-the-Chin Finish: Apply the choking forearm across the opponent’s jaw rather than under the chin. With both arms trapped in crucifix, the jaw pressure creates extreme discomfort that either forces a tap directly or causes the opponent to lift their chin to relieve pressure, opening space for the forearm to slide underneath into a clean blood choke. (When to use: When the opponent aggressively tucks their chin and you cannot thread the forearm underneath cleanly)

Short Choke from Crucifix: Rather than threading the full forearm under the chin, use just the wrist and lower forearm in a compressed choking position. Grip the back of your own head with the choking hand and use the non-choking arm to push the opponent’s head forward into the choke. This variation requires less space to lock and works well when the opponent keeps their chin tight. (When to use: When there is limited space under the chin and you cannot achieve the full depth needed for a standard RNC grip)
