Hello Jonas,
it is great that you try new settings. But i think you changed your settings to
conservative. To raise the value to 102 changes nearly nothing. Of course i only
know how these settings are calculated in fruit 2.1 but i thing this hadn´t
changed in fruit 2.2. in fruit 2.1 the calculations are as follows:
PawnStructureWeight = (option_get_int("Pawn Structure") * 256 + 50) / 100;
pawn_eval=((opening[White] - opening[Black]) * PawnStructureWeight) / 256;
for example:
PawnStructureWeight = (102 * 256 + 50) / 100;
=> PawnStructureWeight = 261
opening[White] is the evaluation for the white pawn structure.
opening[Black] is the evaluation for the black pawn structure.
say opening[White] = 60 and opening[Black] = 10
then pawn_eval = ((60 - 10) * 261) / 256 = 50.97 => pawn_eval = 50
thats the same score as the default value Pawn Structure 100
so my suggestion would be to raise the value much higher than only by 2.
regards
thomas
