No, it is not possible for today's programs to provide optimal analysis for
*any* type of position.  And the program authors cannot possibly account for
every possible nuance of position ahead of time with their software.  Fritz 7
happens to be pretty darn good at a wide range of positions, but the problem is,
without extensive time (months certainly, possibly years) spent with the program
and a solid background in chess, you will not know apriori that Fritz 7 stinks
at analyzing positions of type X, where X might be only very slightly different
from position Y where Fritz 7 is very good at analyzing things and that Fritz 7
is superb at positions of type Z -- say, an open tactical fight with no serious
issues of compensation [a piece and pawn down, but with chances for a strong
attack].

It is even more difficult to recognize such situations and then propose to
tinker with engine settings to produce a better quality analysis in those
positions where the program is not particularly good (using its default
settings).  Better add another year to your studies for those situations....
