Can someone explain that? Set up a 40 game match before bed last night, both
with 512Mbyte Hash Tables running on Pentium IV 3.2GHz. I woke up expecting
a closer match than the 38-2 thrashing Fritz 8 dealt out to Shredder 8. No
draws, and the 2 games Shredder 8 won were when it was playing white.

Game format was the default Fritz Blitz 4' 2". Perhaps I'll try the long
game, as the engines probably aren't making full use of the hash tables with
the Blitz game.

This is poor by any standard, can anyone tell me what Shredder 8 is good for
again?

A more logical conclusion is user error.

You did something wrong.

That's too much hash for blitz. Try less.

It has been shown that Shredder 8 is variable depending on hash size, so you
might have to run the tournament at several different hash sizes to find the
optimum. One test I saw indicated that 256MB hash was optimum for Shredder
8, but that could depend on the machine.

One thing is for sure - it is almost impossible to reproduce any results
with Shredder 8! It is obviously optimized to win the SSDF matches, and
nothing else...

Problem is located between your computer and your seat.

that is not a valid result, something must have set up wrong...

K, thanks for all your great input!

I tried again with 256MB Hash tables, but again 10-0 to Fritz8.

To make sure I wasn't being dumb as many of you hinted at, I set up a
Fritz8-Fritz7 match. The result was 26.5-23.5 to Fritz8. ?!?

Going back to Shredder8, it was newly installed so I tried a reinstall but
it still couldn't live with Fritz8. So before pointing out that the problem
is the user, or is located between the computer and the seat try explaining
the Fritz8 - Fritz7 result.

IIf I may speculate, playing two engines on the same computer may be
misleading if one of them is running the game. I donŒt know if this is
true, but for example, Fritz may be keeping its hash table between moves
and erasing ShredderŒs, or not be optimized to run the Shredder software
under Fritz, or the two programs may not be equivalent when sharing the
resources, or if one wants to be paranoiac, maybe the Fritz programmers
put in a routine to screw up shredder...

On the other hand, maybe you forgot and left Shredder in one of the easier
settings where it intentionally makes mistakes.

Another posibility. Is your copy of Shredder 8 engine legit? The
programmer has the engine play poorly after the 16th or 25th move,(I
forget which) if you are using a warezed copy.

It looks like a book problem, that it plays the same losing/winning lines
again and again. I think one should use the Nunn's tables, though they are
not perfect, while one engine might already have learning.
