What is Craig Jones Triangle to Leg Lock System?
The Craig Jones Triangle to Leg Lock System is a BJJGraph study guide for connecting upper-body submission threats with controlled leg-entanglement opportunities.
Systematic Submission Dilemmas is a focused instructional companion for studying triangles alongside leg attacks. Craig Jones’s published syllabus includes transitions between these families and commentary on grappling exchanges. This guide concentrates on choosing a branch rather than treating every defended triangle as an automatic leg entry.
The practice sequence is BJJGraph’s own study plan, not an official course syllabus. It assumes familiarity with the starting positions and access to coaching for the actual techniques. Begin with one triangle situation and one leg-control destination. If the required connection disappears, retaining guard or resetting may be the more useful decision. The goal is a better explanation of the exchange, not a promise that either submission must succeed.

Systematic Submission Dilemmas: High Level Triangle and Leg Lock Combos
with Craig Jones
Who it suits: Experienced no-gi students who already practise triangles and leg control with a coach; the course includes advanced leg attacks.
Connects triangle attacks with lower-body entanglements rather than treating each submission as an isolated finish.

Core Principles
- Identify the defensive reaction before deciding whether to change attacks.
- Keep a positional fallback when neither submission branch is supported.
- Treat reaching an entanglement and finishing a submission as separate skills.
- Use a small set of familiar positions before adding more variations.
- Agree permitted submissions and reset signals before the round.
- Evaluate the quality of a decision independently from whether it produced a tap.
Key Components
Starting triangle situation (Give the decision exercise a familiar upper-body starting point.) Select a triangle entry or control that both partners already understand and can practise without rushing the finish.
Reaction identification (Make the reason for switching visible to both partners.) Ask the defender to show an agreed response and have the attacker describe what remains controlled.
Leg-control destination (Separate an entry decision from submission finishing pressure.) Choose a single leg entanglement with a coach and identify the requirements for reaching it without an uncontrolled scramble.
Fallback position (Keep an unsuccessful branch from becoming a forced attack.) Name a guard or other position to recover when the intended entry no longer has adequate control.
Exchange review (Build a usable decision map from observed rounds.) Record the reaction, selected branch and resulting position after each short practice sequence.
Implementation Sequence
-
Set the boundaries: Agree which leg attacks are permitted in this session, a comfortable starting position and an immediate reset signal.
-
Rehearse the starting control: Practise the triangle situation cooperatively. Use a coach’s feedback to resolve uncertainty before adding a transition.
-
Identify one response: Let the defender give one agreed reaction. Pause and describe whether the original control remains useful.
-
Select the branch: Choose between maintaining the current position, moving toward the selected leg control, or recovering guard. Avoid forcing a preset chain.
-
Confirm the destination: End the repetition at a stable position, with no finishing pressure needed to count the entry. Reset if either partner is unsure.
-
Vary and review: Add a second reaction, then compare the resulting decisions. Review the relevant course demonstration when the same control problem repeats.

How to Measure Your Progress
Reaction recognition: Check whether the attacker can explain the response that prompted a change. Proficiency indicators:
- Names an observed reaction
- Distinguishes a reaction from a lost grip
- Can explain why staying put was also an option
Destination clarity: Evaluate whether both partners recognise the end of the entry drill. Proficiency indicators:
- Names the intended position
- Stops at stable control without finishing pressure
- Resets when the destination is not achieved
Fallback selection: Review what happens when neither attacking branch remains available. Proficiency indicators:
- Can identify a guard-recovery option
- Does not chase a loose limb through a scramble
- Can describe the next study problem
Practice consistency: Assess whether the drill stays within the pair’s agreed scope. Proficiency indicators:
- Uses agreed submissions only
- Responds immediately to stop signals
- Separates technical uncertainty from resistance
Take one idea into your next session
BJJGraph suggestion: pause after a defensive reaction, name the available control position, then reset if neither branch is secure. Agree allowed leg attacks beforehand.
