Conceptual layer
Concepts
Concepts pages sit above the technique library. They explain how techniques relate to each other strategically — how grips escalate, what objectives each range serves, and how individual techniques become systems through dilemmas. Every claim here is grounded in and linked to at least one technique page.
Technique pages describe positions and submissions — what they are, how they work mechanically, and which invariables they express. Concepts pages describe how to think about techniques together: as sequences, as strategic objectives, as dilemmas where defending one threat opens another. They are the layer that connects individual technical knowledge into a functional game.
A practitioner can know every technique on this site and still not understand why certain grip choices lead to certain entries, or why a given position forces a choice between two bad options. Concepts pages address that gap directly.
How grips escalate
A gripping sequence is a chain of grip upgrades where each step either achieves the goal or forces a defensive reaction that opens the next step. These pages express universal invariables INV-01 and INV-07 — connection and connection before attack — applied at standing and seated ranges.
What each range is for
At every range, each player has a primary objective. Objectives are not technique-specific — they are the strategic goals that techniques serve. Understanding objectives allows a practitioner to evaluate whether a technique choice is appropriate for the situation, not just whether it is executed correctly.
Why individual techniques become systems
A dilemma is a structural relationship where the defence of each threat is the setup for the other. It is not two techniques that happen to be available from the same position. It is the mechanism that turns a position into a system — where the opponent cannot be correct on both threats at the same time.
How guard positions become attack platforms
The seven guard families in no-gi grappling — closed, half, butterfly, X-guard, De La Riva, shin-shield, and seated. Each is a system of related sweeps, submissions, and back takes tied together by a shared positional condition and resolved through dilemmas.
How passes become systems
The five passing families in no-gi grappling — knee slice, half guard passing, leg drag, torreando, and smash pass. Each is a system of related passes tied together by a shared mechanic and resolved through dilemmas with the bottom player's guards.
How scrambles resolve
The five central scrambles in no-gi grappling — dog fight, turtle, late leg-entanglement entries, referee's position dynamics, and back-take scrambles. Every scramble resolves through the same dominate-neutralise-capitalise hierarchy; these pages name each scramble so it can be drilled rather than improvised.
How finishes become systems
The six submission hubs in the Danaher framework — kimura, triangle, armbar, leg locks, guillotine, and RNC. Each is a family of finishes that share a unifying mechanic and can be expressed from many positions, not a single technique.
How to use these pages
Concepts pages are most useful after you have some working knowledge of the positions they reference. A practitioner who has never trained ashi garami can read the dilemma page, but the implications will be abstract. Return to the dilemma pages after drilling the positions they describe — the concepts will become concrete immediately.
Every claim on a Concepts page is linked to a specific technique page. Follow the links. The invariable statements on Concepts pages point to their source in the Invariables Index, which contains the full definitions.
