Subject: Re: More Ruminations on Fritz 5 SSDF strength

Go up one level in this thread


But looking at some of the games, I noticed that the games where
Fritz 5 doesn't play up to its supposed strength are generally in
openings that are fairly passive in general, like the black side
of the closed Ruy Lopez.  I think anyone will be able to show Fritz
5 getting crushed in closed or semi-closed positions it doesn't
understand (or any other program for that matter).  However, its
lack of positional understanding in some positions in no way
indicates that it is a weak program, as a few have charged (with
somewhat emotional rhetoric stemming from disagreements about
the fairness of how SSDF possibly gave favorable conditions to Fritz
5 in their testing).  Small samples of 10, 20, 30, 40 games mean
nothing.  The only statistically relevant information comes from
samples of hundreds of games, which only SSDF is in the position to
provide.  If you disagree with their data, look to the chess servers
for confirmation of how strong your favorite programs are.  Other
than that, these reports of "CSTAL beats Fritz 3.5 - .5, blah, blah"
are just a waste of time.
