Include pawns in NNUE scaling We now include the total pawn count in the scaling factor for the output of the NNUE evaluation network. This should have the effect of trying to keep more pawns when SF has the advantage, but exchange them when she is defending. Thanks to Alexander Pagel (Lolligerhans) for the idea of using the value of pawns to ease the comparison with the rest of the material estimation.
