Technical Grappling introduces a lot of potential detail to fights that involve locks, throws, ground fighting, and wrestling - with or without weapons. The new mechanics provide a lot of great detail, but require a slight reset in how one thinks about grappling in GURPS.
I game out an
example match between two low-point-value characters (52 points) to show how the system is supposed to work.
The choices might not be the most optimal for all fighters, but the fight shows some of the emergent detail of the system.
