Hi Steffen
Thanks for posting this. PostModernist is a bit clueless about here.
It thinks it is +3.8 :-(
Oddly enough, I do have some code to say that if we've got opposite-
coloured bishops AND < 3 pawns advantage to reduce the score somewhat.
(I think 3/4 of the score for 2 pawns advantage, 1/2 of the score for
1 pawn advantage). But it is switched off if the stronger side has passers
(can't remember why I did that now). Perhaps I should generalize for more
pawns (including passers) to see if they're all on the same side of the
board or damaged in some way, or something. One more thing to consider!
