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:

Else if opponent attempts to pull trapped arm free:

Else if opponent turns into triangle attempting escape:

Else if opponent creates space by posting free arm:

Common Offensive Mistakes

1. Threading leg in front of opponent’s neck instead of behind, creating a front triangle configuration

  • Consequence: Opponent can easily defend by tucking chin and the choke pressure is significantly reduced
  • Correction: Thread the leg deep under the armpit so it emerges behind the opponent’s neck, creating proper back triangle mechanics

2. Locking the triangle too loosely without proper compression of knees together

  • Consequence: Opponent can create space, potentially pull trapped arm free, or escape the position entirely
  • Correction: Pull the locking ankle tightly into the crook of the knee and actively squeeze knees together to eliminate all space

3. Losing chest-to-back connection by sitting up too far or leaning away from opponent

  • Consequence: Opponent can turn into you, potentially escaping to guard or reversing the position
  • Correction: Maintain constant chest pressure against opponent’s back with your weight committed forward onto them

4. Failing to control opponent’s free arm, allowing them to establish defensive grips

  • Consequence: Opponent can grab their own leg to prevent triangle lock or defend against choke finishing attempts
  • Correction: Use your hands to control the free arm by wrist control, overhook, or isolating it away from defensive positions

5. Not angling hips sufficiently toward trapped arm side

  • Consequence: Reduced pressure on the carotid artery and less effective choke mechanics
  • Correction: Actively angle your hips and shoulders toward the trapped arm to create optimal cutting angle across the neck

6. Abandoning position too quickly when opponent defends initial choke attempt

  • Consequence: Missing opportunities to attack multiple submissions and cycle through finishing options
  • Correction: Systematically cycle between rear triangle choke, armbar on trapped arm, and rear naked choke to break down defenses

Training Drills for Attacks

Triangle Entry from Back Control Drill

Start in standard back control with seat belt grip. Partner defends by gripping hands together. Practice threading your leg under their armpit and locking the triangle configuration while maintaining back control. Repeat 10 times each side, focusing on smooth entry without losing position. Partner should provide realistic defensive resistance but allow successful entries.

Duration: 5 minutes per side

Submission Cycling Drill

Establish rear triangle top position. Flow continuously between rear triangle choke attempt, armbar on trapped arm, and rear naked choke for 3-minute rounds. Partner defends each attempt realistically, forcing you to transition between submissions. Focus on maintaining position control throughout all transitions. Reset if position is lost.

Duration: 3-minute rounds

Position Maintenance Under Pressure

Partner starts in rear triangle bottom position and uses full effort to escape for 2 minutes while you focus solely on maintaining the position without finishing submissions. Partner should attempt various escapes: turning in, bridging, pulling trapped arm free, creating space. Your goal is to keep the triangle locked and maintain back connection throughout.

Duration: 2-minute rounds

Triangle Lock Tightness Progression

Establish rear triangle position with compliant partner. Practice the following progression: lock triangle loosely (30 seconds), medium tightness (30 seconds), maximum compression (30 seconds). Partner provides feedback on pressure levels. Focus on understanding the difference in control at each compression level. Repeat for 5 cycles per side.

Duration: 8 minutes total
