/* Adjust knight and rook material values by number of pawns, using
* Larry Kaufmann's formulas: */
misc[side] += rooks[side]*(5-pawns[side])*32;
e_misc[side] += rooks[side]*(5-pawns[side])*32;
misc[side] += knights[side]*(pawns[side]-6)*16;
e_misc[side] += knights[side]*(pawns[side]-6)*16;
Kaufmann's stats are right if you have no mobility detection. Fewer pawns are
better for Rooks and Bishops because of mobility, something that is not a
problem with knights. You have already calculated mobility so you are giving
the bonus/penalty twice for the same thing in a different way. I think a
smaller bonus/penalty for pawn count could give greater benefit in your case.
