Rear Triangle Top is an advanced back control variation where the top practitioner secures the opponent’s back while establishing a triangle configuration with their legs around the opponent’s body and one arm. This position combines the control elements of traditional back control with the limb-trapping mechanics of a triangle, creating a highly effective submission platform. The rear triangle creates a dilemma for the opponent - defending the choke exposes the trapped arm to attacks, while defending the arm allows progression to the rear naked choke or other back attacks. This position is particularly effective in no-gi grappling but can be equally devastating in the gi when properly executed. The rear triangle top position represents a sophisticated evolution of back control, offering superior control compared to standard seat belt positioning. By threading one leg under the opponent’s armpit and locking a triangle around their neck and trapped arm, the top practitioner creates multiple layers of control that significantly reduce the opponent’s defensive options. This position is often entered from standard back control when the opponent attempts to defend the rear naked choke by gripping their own hands together or when transitioning from turtle position. The configuration allows for seamless transitions to various submissions including the rear triangle choke itself, armbar variations, and traditional rear naked choke finishes. From a strategic perspective, the rear triangle top position exemplifies the principle of creating submission dilemmas - forcing the opponent to choose between equally bad defensive options.
Position Definition
- Top practitioner’s legs form a triangle configuration around opponent’s neck and one trapped arm, with one leg threaded under the armpit and across the back of the neck while the other leg locks over the ankle to complete the triangle, creating a secure figure-four lock that controls both head and arm simultaneously
- Top practitioner maintains chest-to-back connection with their torso pressed against opponent’s back, hips oriented toward the trapped arm side to maximize control and create the optimal angle for submissions while preventing opponent rotation away from the triangle
- Opponent is typically seated or on their side with one arm trapped inside the triangle while their body is compressed forward by the leg pressure across their neck and shoulder, limiting their ability to establish defensive frames or recover posture
- Top practitioner’s hands are free to attack the opponent’s free arm, establish grips for chokes, or post for base while the legs maintain primary control of the position, allowing simultaneous control and attack capabilities
- The triangle configuration creates constant pressure on the opponent’s carotid artery on the trapped arm side while controlling their posture and preventing them from turning into the top practitioner or creating escape angles
Prerequisites
- Established back control position with hooks or body triangle
- Opponent’s defensive hand fighting creates opportunity to trap one arm
- Sufficient hip mobility and leg dexterity to thread leg under opponent’s armpit
- Understanding of triangle mechanics and proper leg positioning
- Ability to maintain back control during the transition to triangle configuration
- Opponent positioned in seated or side-lying orientation allowing leg threading
Key Offensive Principles
- Thread the choking leg deep under the opponent’s armpit to create proper angle across the back of their neck rather than the front
- Lock the triangle tight by pulling the locking ankle into the crook of the knee while squeezing knees together to compress the opponent’s neck and trapped arm
- Maintain chest pressure against opponent’s back throughout the position to prevent them from turning into you or creating space
- Control opponent’s free arm with your hands to prevent defensive gripping and create additional submission opportunities
- Angle your hips toward the trapped arm side to increase pressure on the carotid artery and create better finishing mechanics for the choke
- Use your legs to break opponent’s posture forward, bringing their chin to their chest to tighten the choke and reduce defensive options
- Transition fluidly between submission threats - rear triangle choke, armbar on trapped arm, and rear naked choke - to overwhelm opponent’s defenses
Decision Making from This Position
If opponent tucks chin and defends choke primarily:
- Execute Armbar from Back Transition → Armbar Control (Probability: 65%)
- Execute Kimura from Back → Kimura Trap (Probability: 45%)
Else if opponent attempts to pull trapped arm free:
- Execute Tighten Triangle Lock → Rear Triangle (Probability: 70%)
- Execute Rear Triangle Choke Finish → Game Over (Probability: 60%)
Else if opponent turns into triangle attempting escape:
- Execute Extend Hips and Finish Triangle → Game Over (Probability: 55%)
- Execute Aoki Lock to Crucifix → Crucifix (Probability: 50%)
Else if opponent creates space by posting free arm:
- Execute Rear Naked Choke → Game Over (Probability: 65%)
- Execute Attack Free Arm for Control → Gift Wrap (Probability: 50%)
Test Your Knowledge
Q1: What is the optimal hip angle for maintaining rear triangle control and why does this matter? A: Angle your hips toward the trapped arm side at approximately 45 degrees to maximize carotid pressure. This hip orientation creates the cutting angle across the neck that compresses the carotid artery on the trapped arm side. Without this angle, the choke becomes a less effective air choke rather than a blood choke, giving opponent more time to escape.
Q2: Your opponent starts to turn into you to relieve choking pressure - what adjustment do you make? A: Extend your hips away from opponent while simultaneously tightening the triangle lock by squeezing knees together. Use your chest pressure and free hand to prevent their rotation. If they continue turning, use the rotation to transition to crucifix position by controlling their far arm during the turn. Never let them face you completely.
Q3: What are the essential grip priorities when your hands are free in rear triangle position? A: Primary priority is controlling the opponent’s free arm to prevent defensive gripping and frame establishment. Secondary priority is wrist control or collar grip on the trapped arm side to set up rear naked choke or bow and arrow attempts. Your hands should never be idle - they cycle between controlling the free arm and attacking submissions.
Q4: How do you prevent opponent from extracting their trapped arm from the triangle structure? A: Squeeze your knees together tightly to compress the space around the trapped arm. Angle your hips toward the trapped arm side to create pressure that pins the arm against their own body. Use your hands to actively fight any grip breaks on the trapped arm. If they create space, immediately tighten the triangle lock before continuing attacks.
Q5: What is the proper leg threading depth for the rear triangle and why is this critical? A: Thread the choking leg deep under the armpit until your calf crosses behind the opponent’s neck, not in front. The leg should emerge on the opposite side of their neck from where it entered. This creates the proper posterior choking angle that attacks the carotid from behind, making chin tucking an ineffective defense compared to front triangle positioning.
Q6: Your opponent bridges hard and creates space between your chest and their back - how do you recover? A: Immediately follow them with your hips, closing the gap before they can rotate or stand. Use your free hand to push off the mat and drive your chest back into contact. Tighten the triangle lock to restrict their hip movement. If significant space is created, consider transitioning back to traditional back control with seat belt grip before re-establishing the triangle.
Q7: How do you distribute your weight to maintain rear triangle without fatiguing your legs prematurely? A: Let your skeletal structure do the work rather than muscular squeezing. Lock the ankle deep into the knee crook so the figure-four holds itself structurally. Use your body weight draped over the opponent’s back as the primary control force rather than constant leg tension. Reserve active squeezing for moments when you need to tighten during escape attempts or submission finishes. Between attacks, maintain a firm but relaxed triangle lock.
Q8: After your opponent successfully defends the triangle choke attempt, how do you reset without losing position? A: Maintain the triangle lock structure even when the choke is defended. Immediately transition to attacking the trapped arm for armbar or the free arm for kimura control. If opponent creates too much space defending the choke, tighten the triangle and re-establish chest pressure before cycling to the next attack. Never abandon the position just because one submission fails.
