Visual Execution Sequence

Detailed step-by-step description for clear movement sequence visualization:

From a dominant position like mount or side control, you begin by isolating one of the opponent’s arms, pushing it against their neck to set up the choke. Your head is positioned on the same side as the trapped arm, ensuring tight control as you thread your arm around their head and arm, connecting your hands in a figure-four or gable grip. You then position your chest over their shoulder, creating compression by eliminating any space between your body and theirs, while aligning your shoulder to apply pressure directly against their carotid artery. As their resistance weakens, you slide to the side opposite the trapped arm, increasing the angle and pressure, expanding your chest and squeezing with your arms to finalize the blood choke until they submit or tap out.

Template: “From mount or side control, isolate their arm against their neck and position your head on the same side. Thread your arm around their head and arm, connecting hands in a grip. Position chest over their shoulder for compression, aligning shoulder to carotid artery. Slide to the opposite side, expand chest, and squeeze for the submission.”

Execution Steps (Numbered Sequence)

  1. Setup Requirements: Establish dominant position (mount or side control) with control
  2. Initial Movement: Isolate opponent’s arm, pushing it against their neck
  3. Opponent Response: Opponent may frame or attempt to pull arm down
  4. Adaptation: Position head on trapped arm side, thread arm around head and arm
  5. Positioning: Connect hands in figure-four or gable grip, chest over shoulder
  6. Pressure Application: Align shoulder to carotid artery, eliminate space
  7. Completion: Slide to opposite side, expand chest, squeeze for submission

Key Technical Details

Critical elements that determine success:

  • Grip Requirements: Figure-four or gable grip for secure arm and head control
  • Base/Foundation: Chest and shoulder alignment for effective pressure
  • Timing Windows: Execute when opponent’s arm is framed or exposed
  • Leverage Points: Shoulder pressure on carotid artery for blood choke
  • Common Adjustments: Adjust angle by sliding side based on resistance

Success Modifiers

Factors that increase/decrease probability:

  • Setup Quality: Strong arm isolation and head control (+/-15%)
  • Timing Precision: Executing during opponent’s framing or escape attempt (+/-20%)
  • Opponent Fatigue: Reduced defensive capability over time (+/-5%)
  • Knowledge Test Performance: Understanding pressure mechanics (+/-10%)
  • Positional Dominance: Control from mount or side control (+/-10%)

Counter-Attack Analysis

Common Counters

Opponent responses with success rates:

  • Create Space Defense: Framing to create space and relieve pressure → Submission Escape (Success Rate: 40%, Conditions: early recognition)
  • Bridge and Roll: Explosive bridge to disrupt position → Guard Recovery (Success Rate: 35%, Conditions: strong base)
  • Arm Extraction: Pulling trapped arm out before choke sets → Neutral Position (Success Rate: 30%, Conditions: quick reaction)
  • Hand Fighting: Breaking grip before pressure application → Defensive Position (Success Rate: 25%, Conditions: grip awareness)
  • Hip Escape: Shrimping to recover half guard → Half Guard Recovery (Success Rate: 20%, Conditions: space creation)

Format: [[Counter Technique]] → [[Result State]] (Success Rate: X%, Conditions: [when applicable])

Decision Logic for Opponent Behavior

If [arm triangle setup] is recognized early:
- Execute [[Create Space Defense]] (Probability: 40%)

Else if [pressure] is not yet applied:
- Execute [[Arm Extraction]] (Probability: 30%)

Else if [base] is strong:
- Execute [[Bridge and Roll]] (Probability: 35%)

Else if [grip] can be broken:
- Execute [[Hand Fighting]] (Probability: 25%)

Else [optimal submission execution]:
- Accept submission (Probability: Success Rate - Modifiers)

Defensive Considerations

Common Threats During Attempt

Primary risks while attempting this submission:

  • Position Loss: Opponent bridges or rolls → Guard Recovery (Threat Level: Medium)
  • Counter Submission: Opponent attacks with leg locks if hips exposed → Leg Lock Control (Threat Level: Low)
  • Escape: Opponent extracts arm and creates space → Neutral Position (Threat Level: Medium)
  • Stalemate: Opponent tucks chin and stalls → Defensive Position (Threat Level: Low)

Format: [[Threat Type]] → [[Resulting Position]] (Threat Level: X)

Defensive Strategies

Methods to mitigate threats:

  • Arm Control: Maintain tight isolation of opponent’s arm to prevent extraction
  • Pressure Maintenance: Keep chest-to-shoulder connection to limit space
  • Hip Awareness: Position hips to avoid leg lock entries
  • Angle Adjustment: Slide to side early to prevent bridging escapes
  • Grip Security: Use strong grip to resist hand fighting attempts

Educational Content

Expert Insights

Commentary as if from recognized authorities:

  • John Danaher: “The arm triangle is a fundamental submission that succeeds through precise shoulder alignment rather than brute strength. The key is understanding that the pressure must be applied to the carotid artery using the opponent’s own shoulder as a lever. This technique teaches critical principles of mechanical advantage that apply to all chokes.”
  • Gordon Ryan: “In competition, the arm triangle is a high-percentage finish from mount because it exploits defensive framing. I use strategic weight distribution to maintain shoulder connection to their jaw, preventing escapes. The submission demonstrates how to turn an opponent’s defense into a vulnerability.”
  • Eddie Bravo: “The arm triangle integrates well with unorthodox positions like the Truck, creating dual threats of choke and positional advancement. It often forces opponents to expose other submissions when defended. This technique shows how traditional chokes can be adapted for modern grappling dynamics.”

Each insight should focus on one key technical or strategic element.

Common Errors

For knowledge test generation:

  • Error: Squeezing with arms only instead of using shoulder pressure

  • Why It Fails: Ineffective pressure leads to fatigue without submission

  • Correction: Focus on aligning shoulder to carotid artery and expanding chest

  • Recognition: Opponent does not show signs of distress despite grip

  • Error: Poor alignment of shoulder pressure

  • Why It Fails: Insufficient compression on carotid artery for blood choke

  • Correction: Ensure shoulder is directly over opponent’s shoulder and neck

  • Recognition: Choke feels weak despite tight grip

  • Error: Rushing the finish without eliminating space

  • Why It Fails: Allows opponent to create defensive space and escape

  • Correction: Maintain chest-to-shoulder connection before sliding to side

  • Recognition: Opponent easily frames or extracts arm during attempt

Timing Considerations

When to attempt this submission:

  • Optimal Conditions: When opponent’s arm is framed or exposed during escape attempt
  • Avoid When: Opponent maintains strong defensive posture with chin tucked
  • Setup Sequences: After failed mount escapes or other submission threats
  • Follow-up Windows: Must complete within 5-10 seconds to prevent counter or fatigue
