I could not do my eval incrementally.  It would cost a fortune.  Because
every piece influences the score of every other piece, pieces influence pawns,
pawns influence pieces, etc...  So I wouldn't have an _exact_ score at each
ply either, since I could not possibly afford to do all the things I do and
keep them incrementally current.
