This is the backport of tuned piece values. We needed to change also the psqt tables so that their values, that are relative to piece values, remain the same. Amost no change after 999 games: Mod vs Orig 594-495 + 2 ELO points so well within error bar It was expected somehow given the very little change of the parameters values.
