17:Nd5 looks like the loosing move. Fritz (and also it seems H7) misjudge
how weak the white pawns on d5 and b5 becomes. The point is that these
pawn weaknesses (as it turns out) are more important than the weakening
of blacks king position.
Why does strong programs not do the following: If a "unbalanced" position arises
where weak pawns have to be judged against say dynamic chances, then compute
(besides the usual search) a few very long "test" variations to check whether
the weak pawns compensate the weakening of blacks king position. It seems to me
that strong programs should have no problems in relizing (within seconds) that
the weak pawns eventually will get lost with no compensation.
I have found the same problem in other strong programes. The programs score
begin to drop, but far to late. A few trail games (playing out say 20 plies)
will reveal that the weak pawns are for taking.
