I like Dann Corbit's answer.  If the analyses are VERY important to you then use
several different engines and compare the results.  Also, note that the purpose
of the analyses does have an impact on what you should do.  Analyses of casual
blitz games should probably be limited to very fast blunderchecking.  Any engine
would do just fine for that.  Analyses used to support correspondence chess
should be much more thorough.  One might conceive other situations where even
more detailed analyses might be needed.

There is no way anyone can say with absolute certainty which chess-playing
program is best for "analysis" since such a statement would have to be based on
extensive testing and that has not been done, insofar as I know.

Dann said he preferred Shredder and understandably so since Shredder is
currently at the top of the SSDF rating list.  I prefer Fritz because Fritz's
PVs are more useful to me than Shredder's PVs.

If you are doing endgame analyses you will want to use tablebases [i.e. your
chess-playing program should be able to use tablebases.]

What else can I say?  Until you pin down the types and purposes of your
analyses, I can only give you generalities.  For me to be specific you must be
specific.  You still have not said what kind of computer you are using.
