Re: [Bug-gnubg] GNU multi-ply analysis

[Øystein O Johansen]

Short answer: It all written in the function ClassifyPosition in eval.c

Race and contact should be obvious. Crashed position net is used when one
of the players has 6 or less loose chequers with the remaining 9 chequers
born off or crashed on the ace or deuce point. (And you may have the
3-point as well) Read the code.

ClassifyPosition is called before each evaluation, so when it's looking
ahead to deeper plies, it will classify each future position through this
function. As a 1-ply evaluation is the average of all the 36 1-ply
positions it may be a average of evaluations from different evaluators.
