Monoplata from Guard | BJJ Submission | BJJ Graph

LLM Context: Submission Data Structure

Purpose: Advanced shoulder lock submission from guard. Terminal state with HIGH injury risk. Requires exceptional control and sensitivity. Safety is absolutely paramount.

Setup Requirements Checklist:

• Starting position: Closed Guard Bottom (S015) with strong control
• Position control quality: Dominant with arm trapped
• Required grips: Arm controlled across body, wrist grip
• Angle optimization: Perpendicular body position
• Opponent vulnerability: Arm trapped, shoulder rotated internally
• Space elimination: Leg over shoulder eliminating escape routes
• Timing recognition: Arm positioning error creates opportunity

Defense Awareness:

• Early defense (setup <70% complete): 55% escape success
• Mid defense (leg over shoulder): 40% escape success
• Technical escape (rotation beginning): 25% escape success
• Inevitable submission: 0% escape → TAP IMMEDIATELY

Safety Q&A Patterns: Q: “How fast should rotation be applied?” A: “EXTREMELY SLOW. Shoulder locks require 5-7 seconds minimum. Rotator cuff tears occur rapidly with fast rotation.”

Q: “What are the tap signals?” A: “Verbal ‘tap’ LOUDLY, physical tap with free hand. Shoulder locks can prevent hand reach - verbal is primary.”

Q: “What if partner doesn’t tap?” A: “STOP if shoulder makes sound, arm goes limp, partner shows extreme distress, ANY uncertainty.”

Q: “What are injury risks?” A: “Rotator cuff tear (4-12 weeks), labrum tear (surgery possible, 3-6 months), shoulder dislocation (8-16 weeks).”

Decision Tree for Execution:

IF guard_quality >= 80% AND arm_trapped_correctly:
    → Attempt submission (Success Rate: [skill_level]%)
ELIF opponent_defending AND rotation_started:
    → SLOW rotation, monitor tap signals
ELIF submission_locked AND tap_received:
    → RELEASE IMMEDIATELY per protocol
ELSE:
    → Maintain guard, seek safer attack

⚠️ SAFETY NOTICE

This submission can cause ROTATOR CUFF TEARS and SHOULDER DISLOCATION if applied improperly.

• Injury Risks:
  • Rotator cuff tear (4-12 weeks recovery, possible surgery)
  • Shoulder joint capsule damage (6-16 weeks recovery)
  • Labrum tear (surgery often required, 3-6 months recovery)
  • Shoulder dislocation (8-16 weeks recovery, chronic instability risk)
• Application Speed: EXTREMELY SLOW - 5-7 seconds minimum rotation
• Tap Signals: VERBAL “tap” is primary (shoulder position may prevent hand tap)
• Release Protocol: Stop rotation immediately, release arm, release leg, check shoulder
• Training Requirement: ADVANCED ONLY with mandatory instructor supervision
• Never: Apply rapid rotation or continue past resistance point

Remember: Shoulder injuries are career-ending and life-altering. This technique requires EXCEPTIONAL control and partner trust. When in doubt, release.

Overview

The Monoplata is an advanced shoulder lock executed from guard by trapping the opponent’s arm across their body and using leg pressure combined with body rotation to isolate and attack the shoulder joint. Unlike the traditional omoplata which attacks with both legs, the monoplata uses a single leg configuration, creating a unique angle of attack on the rotator cuff.

This submission requires exceptional technical precision and control sensitivity. The setup involves trapping the opponent’s arm similar to an omoplata entry, but instead of rolling forward, you maintain bottom position and use your body’s rotation and leg pressure to create internal rotation and hyperextension of the shoulder joint.

From Closed Guard Bottom (S015), the monoplata is typically attempted when the opponent makes arm positioning errors or when transitioning from failed omoplata or triangle attempts. The technique exemplifies advanced guard play and shoulder lock mechanics.

Visual Finishing Sequence

From closed guard, you trap your opponent’s right arm across their body, controlling their wrist. You bring your left leg over their shoulder and back, while your right leg remains as a guard hook. Your body rotates perpendicular to theirs, creating a leverage angle. Your left leg presses down on their shoulder while you pull their wrist, creating internal rotation and extension of the shoulder joint.

The opponent experiences intense pressure in their shoulder, rotator cuff stretching beyond its range. Recognizing the shoulder lock is progressing toward injury, they tap repeatedly with their free hand or verbally. You immediately stop all rotation and pressure, releasing the arm and leg control.

Body Positioning:

• Your position: On back/side, perpendicular to opponent, left leg over their shoulder, right leg as hook, wrist controlled
• Opponent’s position: Posture broken, right arm trapped across body, left arm free to tap, limited mobility
• Key pressure points: Shoulder joint in internal rotation and extension
• Leverage creation: Leg pressure + body rotation + wrist control = shoulder lock

Execution Steps

SAFETY REMINDER: Apply rotation EXTREMELY SLOWLY over 5-7 seconds. Shoulder injuries occur rapidly. Watch for ANY discomfort signals.

1. Initial Setup (Arm Trap Phase)

   • From closed guard, trap opponent’s right arm across their centerline
   • Control wrist with your right hand
   • Begin breaking posture
   • Safety: Ensure partner’s left arm is free to tap

2. Leg Position (Triangle Formation)

   • Bring left leg over opponent’s right shoulder and behind their back
   • Maintain right leg as guard hook
   • Begin rotating body perpendicular
   • Partner check: Leg positioning comfortable, arm isolated

3. Body Rotation (Angle Creation)

   • Rotate your body perpendicular to opponent
   • Pull their wrist toward your chest
   • Position left leg pressing on shoulder
   • Speed: SLOW rotation over 2-3 seconds
   • Watch for: Partner’s shoulder position, early distress

4. Pressure Application (Lock Initiation)

   • Press down with left leg on their shoulder
   • Pull wrist creating internal rotation
   • Rotate body further if needed
   • Speed: EXTREMELY SLOW pressure increase over 3-4 seconds
   • Monitor: Verbal tap signals, shoulder position, partner’s face

5. Progressive Tightening (Submission Phase)

   • Incrementally increase leg pressure
   • Maintain wrist pull and rotation
   • Feel for resistance points
   • Critical: STOP at any shoulder resistance or discomfort
   • Time: 2-3 seconds maximum additional pressure

6. Tap Recognition & Release (Safety Phase)

   • LISTEN FOR VERBAL TAP (primary signal)
   • RELEASE IMMEDIATELY:
     • Stop all rotation and pressure instantly
     • Release wrist control
     • Remove leg from shoulder
     • Open guard completely
   • Post-submission: Ask “Shoulder okay?”, observe mobility, check for pain

Total Time: 5-7 seconds minimum from lock to tap in training. Drilling should be 10-15 seconds.

Anatomical Targeting & Injury Awareness

Primary Target

• Anatomical Structure: Shoulder joint (glenohumeral joint), rotator cuff muscles (supraspinatus, infraspinatus, teres minor, subscapularis)
• Pressure Direction: Internal rotation combined with extension and posterior pressure
• Physiological Response: Rotator cuff stretching, joint capsule stress, labrum strain

INJURY RISKS & PREVENTION

Potential Injuries:

• Rotator Cuff Tear: Most common. Muscles tear under rotation stress. Severity: Moderate to Severe (4-12 weeks, possible surgery). Prevention: SLOW application, stop at resistance.
• Labrum Tear: Cartilage ring tears. Severity: Severe (surgery often required, 3-6 months recovery). Prevention: Never force past resistance point.
• Shoulder Dislocation: Joint separates. Severity: Critical (8-16 weeks, chronic instability risk). Prevention: Stop immediately if joint feels loose.
• Joint Capsule Damage: Connective tissue tears. Severity: Severe (6-16 weeks, possible chronic issues). Prevention: Extremely slow application only.

Prevention Measures:

• Apply ALL pressure extremely slowly (5-7 seconds minimum)
• Never rotate explosively or jerk the shoulder
• Stop immediately at ANY resistance or discomfort
• Verbal check-ins: “Shoulder okay?” “Pressure level?”
• Partner must understand this is high-risk technique
• Release immediately upon tap
• After release, check shoulder range of motion

Warning Signs to STOP:

• Partner taps (primary)
• Shoulder makes popping/cracking sound
• Arm shows unusual positioning
• Partner’s face shows extreme distress
• Verbal distress signals
• Shoulder feels loose or unstable
• ANY uncertainty - RELEASE IMMEDIATELY

Training Progressions & Safety Protocols

Phase 1: Technical Understanding (Week 1-3)

• Study shoulder anatomy extensively
• Understand injury mechanisms completely
• Watch multiple instructional videos
• Practice positioning without partner
• Learn tap signals and release protocol
• NO LIVE APPLICATION
• Instructor explains injury risks in detail

Phase 2: Controlled Introduction (Week 4-6)

• ZERO resistance from partner
• Focus ONLY on positioning and angle
• NO pressure application
• Speed: 15-20 seconds per rep
• Partner taps at 10% pressure
• Mandatory instructor supervision
• Goal: Understand positioning without risk

Phase 3: Minimal Pressure (Week 7-10)

• Partner provides minimal resistance
• Apply 20-30% pressure maximum
• Speed: 10-12 seconds per rep
• Partner taps immediately when feeling position
• Continue instructor supervision
• Develop sensitivity to shoulder position
• Goal: Feel the position without finishing

Phase 4: Progressive Application (Week 11-16)

• Partner provides light resistance
• Apply 40-50% pressure maximum
• Speed: 7-10 seconds per rep
• Partner taps at first significant pressure
• Emphasis on control over completion
• Goal: Recognize effective position

Phase 5: Advanced Integration (Week 17-24)

• Light rolling integration
• Apply 50-60% pressure maximum
• Speed: 5-7 seconds minimum
• Partner taps early
• Never apply in hard rolling
• Goal: Safe application under light resistance

Phase 6: Expert Application (6+ months experience)

• Sparring integration with extreme caution
• NEVER apply at competition speed in training
• Always prioritize partner safety
• Mentor others on safety
• Goal: Mastery = never injuring partners

CRITICAL: This technique requires MONTHS of practice before live application. Most academies restrict it to brown/black belts only. Rushing progression causes serious injuries.

Expert Insights

John Danaher Perspective

“The monoplata represents one of the most technically complex and dangerous submissions in jiu-jitsu. The shoulder joint’s vulnerability to rotational stress makes this technique particularly risky. The key detail is maintaining precise angle control - your body must be perfectly perpendicular to create the correct leverage vector. In training, your goal should be to achieve the locked position and recognize inevitability, then release. The actual shoulder rotation to completion has no training value and carries significant injury risk. Release immediately upon tap - shoulder damage occurs within 1-2 seconds of resistance.”

Gordon Ryan Perspective

“I rarely use monoplata in competition because the setup is complex and escapes exist. When I do use it, the finish is controlled and progressive. In training, I almost never finish this technique - I achieve the position, hold it until partner taps to position, then release. The injury risk is too high for training. Your partners’ shoulders need to last their entire careers. If you’re finishing monoplatas fully in training, you’re going to run out of partners who trust you.”

Eddie Bravo Perspective

“The monoplata fits into the 10th Planet system as an advanced option from rubber guard and other positions. But it’s one technique where I tell students: in training, treat this like a position, not a finish. Get the lock, feel the control, let partner tap to position, release. Competition is different - if you’re an advanced competitor and the moment calls for it, you know how to finish. But day-to-day training? Control and safety over completion every single time.”

Common Errors

Technical Errors

Error 1: Poor Arm Isolation

• Mistake: Attempting monoplata without arm fully trapped
• Why it fails: Opponent can pull arm free or rotate out
• Correction: Ensure arm is across centerline and controlled before leg positioning

Error 2: Incorrect Body Angle

• Mistake: Not rotating perpendicular to opponent
• Why it fails: Wrong angle reduces leverage, ineffective shoulder pressure
• Correction: Body must be 90 degrees to opponent’s torso

Error 3: Leg Position Too High or Low

• Mistake: Leg over shoulder but wrong position on arm
• Why it fails: Cannot control shoulder properly
• Correction: Leg must be across shoulder blade and upper arm

SAFETY ERRORS (CRITICAL)

DANGER: Rapid Rotation

• Mistake: Rotating body quickly to finish
• Why dangerous: Rotator cuff tears in under 1 second with rapid rotation
• Injury risk: IMMEDIATE rotator cuff tear, possible labrum damage
• Correction: 5-7 seconds minimum rotation speed
• This causes the most shoulder injuries in BJJ

DANGER: Ignoring Tap Signals

• Mistake: Not hearing verbal tap or continuing after tap
• Why dangerous: Shoulder damage occurs extremely rapidly
• Injury risk: Permanent shoulder damage, possible surgery required
• Correction: LISTEN for verbal tap, release immediately
• Shoulder locks can prevent physical taps - verbal is primary

DANGER: Training at Competition Speed

• Mistake: Applying full pressure/speed in drilling
• Why dangerous: Partner cannot protect shoulder adequately
• Correction: Always train slowly, competition speed only in competition
• Save full application for competition or never

Knowledge Assessment

Question 1: Setup Recognition (Safety Critical)

Q: What position and controls must be established before attempting this submission safely?

A: Closed Guard Bottom (S015) with arm trapped across opponent’s body, wrist controlled, leg over shoulder and back, body perpendicular, partner’s free arm able to tap, verbal tap signal established. Most importantly: partner must be advanced enough to recognize shoulder danger and tap early.

Why It Matters: Monoplata has highest injury risk of common submissions. Proper setup and partner awareness are essential.

Question 2: Safety Understanding (CRITICAL)

Q: Why is this submission more dangerous than other locks, and how should it be trained?

A: Shoulder joint extremely vulnerable to rotational stress. Rotator cuff tears occur in 1-2 seconds with improper application. Training protocol: 5-7 seconds minimum application, stop at 50-60% maximum pressure, verbal tap as primary signal, never in hard rolling, advanced practitioners only, mandatory instructor supervision initially, focus on position achievement rather than completion.

Why It Matters: More BJJ practitioners have ended training careers from shoulder lock injuries than any other submission type. Understanding danger prevents injuries.

Question 3: Release Protocol (Safety Critical)

Q: What is immediate action when partner taps, and what must you check after release?

A: Immediate: Stop all rotation/pressure instantly, release wrist, remove leg from shoulder, open guard. After Release: Ask “Shoulder okay?”, observe shoulder mobility, check for pain/limited motion, watch for distress signals, allow partner to test shoulder gently, stop training if any concerns. Time: 3-4 seconds from tap to complete release.

Why It Matters: Proper release prevents injury during disengagement. Post-release check ensures no damage occurred. Shoulder injuries can worsen with continued training.

Question 4: Injury Awareness

Q: What are the primary injuries from this technique and their recovery times?

A:

• Rotator cuff tear: 4-12 weeks, possible surgery
• Labrum tear: Surgery often required, 3-6 months recovery
• Shoulder dislocation: 8-16 weeks, chronic instability risk
• Joint capsule damage: 6-16 weeks, possible permanent limitations

All injuries can be career-ending for grapplers. Prevention requires slow application and early tapping.

Why It Matters: Understanding injury severity creates appropriate respect and caution. These aren’t minor injuries.

Question 5: Training Restrictions

Q: Who should learn this technique and under what conditions?

A: Advanced practitioners only (typically brown/black belt), mandatory instructor supervision for initial 50+ repetitions, experienced training partners who understand shoulder locks, never in beginner classes, restricted use in rolling (light only), never at full speed in training, many academies restrict or ban entirely.

Why It Matters: This technique’s injury risk requires restrictions. Not appropriate for all practitioners or all training contexts.
