The idea that the score should match the final position of the PV is clearly
incorrect, IMHO.

My interpretation of the score has been that it is either an evaluation of the
position being analyzed or it represents an evaluation of the position that
would occur immediately after the recommended move is played.  If the engine
"thinks" that the move is best, then the evaluation before and after the
recommended move is played would be the same, it seems to me.

I agree that Shredder's "PV" is flawed and that is irritating.  However, it
would be a bad mistake to assume that the moves of Fritz's PV are "good."
