Submission Systems

A submission system exists because a single unifying mechanic can be expressed from many different positions. The armbar's hyperextension works from guard, mount, side, back, and standing. The triangle's figure-four leg geometry works from every position the legs can reach the opponent's upper body. The kimura's rotational shoulder lock applies across guard, side, north-south, and back. When a finish is position-agnostic, the finishes it enables become a system rather than a list.

Each system below is one of the six canonical hubs. The heel hook system is treated separately because of its safety profile, and the anaconda / d'arce pair is extracted from the guillotine family because those two finishes form a coherent sub-system. Every page lists the techniques in the system, the invariables it expresses, the dilemmas it creates with other systems, and a progression from foundational to competition-ready.
