It depends on the program.

Chessmaster6000 likes to create passed pawns in queen endgames and can evaluate
positions with one pawn down as a clear advantage because of the passed pawn.

Maybe it is too optimistic about passed pawn because it does not evaluate the
chances of the opponent to do perpetual check and there are cases when it
evaluates drawn position of KQP vs KQ as a big advantage for the side with the
pawn but I think that the evaluation of it is better than the evaluation of
other programs in most of the cases.

It is the only program(from the programs that I have) that evaluated the
position of kasparov against the world(KQP vs KQPP) as a clear advantage for
kasparov inspite of the fact that kasparov was a pawn down.
