Hello Ed,

that is somehow similar to my webpage on that, were only average exchange values
have been established. In Smirf the real evaluation will be overlayed by detail
evaluations, where espacially weaker pieces will gain some profit (but only if
well developped).

>Here is a martix you should compose and test your weights:

>Knight + Rook vs. Chancellor
Smirf --> equal, +0.00

>Knight + Bishop vs. Chancellor
Smirf --> good,  +0.54

>Chancellor + Pawn vs. Queen
Smirf --> good,  +0.46

>Archibishop + Pawn vs. Chancellor
Smirf --> bad,   -1.38

>Queen vs. Archibishop + Knight
Smirf --> bad,   -0.68

>Queen vs. Archbishop + Bishop
Smirf --> bad,   -1.22

>Chancellor + Bishop vs. Archbishop + Rook
Smirf --> equal, +0.01

>Rook vs. Knight + Knight
Smirf --> bad,   -0.69

>Rook + Pawn vs. Archbishop
Smirf --> bad,   -0.22

>I have many more of these in the evaluation function that STATISTICALLY

[...]

It will be up to some matches to see the correctness of those average exchange
values.

Regards, Reinhard.
