Yes I was also thinking it was odd...
I expected also a bigger difference ... Am not sure why this is ...
my eval starts with:
int generatePositionScore(int alpha, int beta)
{
evalCounter++;
if (isDraw()) return 0;
}
scoreType score = p.materialWhite - p.materialBlack;
//lazy eval
if (score - 150 > beta) return score;
if (score + 150 < alpha) return score;
...
}
It can be that the first part which I call lazy eval catches a lot of positions
.... or there is a much bigger hotspot as the evaluation currently.
I will run a profile to see if I can find more out ....
