GNU Chess version 1 is long dead (I hope).

Is this an Apple application claiming to be version 1, as they
seem to have put a gui wrapper around GNU Chess, and confused a
lot of people on version numbers.

GNU Chess (the engine not the GUI) shows it's evaluation in
"centipawns". So "-17" in GNU Chess typically means the player
who is to move (the computer?) has a positional disadvantage
estimated to be worth 17% of a pawn.

Thus pieces are assigned values thus;

#define ValueP   100  // (by definition of value system)
#define ValueN   350 // N for Knight, K for King, obviously?
#define ValueB   350
#define ValueR   550
#define ValueQ   1100
#define ValueK   2000
