Engine experiment wanted

Archived from groups: rec.games.chess.computer (More info?)

I've had an engine match on my computer with Fritz 8 and Shredder 9.
My computer : ca.630 Mhz, 128 Mb.
Hashtables: 28 Mb
Time: 1 min. p.engine

RESULT: Fritz8-Shredder9: +20=1-1 (20,5-1,5)

I'm very surprised, allthough the search depth of Shredder falls to 1 or 2
ply after about 20 moves. I've original software.
So, can anyone with the same kind of computer( an oldy) and with these
engines try this match out for me, so I can understand if my shredder is any
good?
Also, if you want , I would like to know the results on faster
computers.(same hash tables).

Thanks in advance,
RB

The Shredder book wás loaded! (Allthough I don't see why that should make a
difference . No book on either side could also be o.k)

I had heard Fritz was better at blitz (1 min) also, so I was curious. I
thought it could have something to do with processor-speed, because : In
long matches Shredder does hold it's ground! When time is short, less than 1
or 2 sec. per move , in the endgame or in bullet matches, it starts to
blunder (for instance giving away mate in 1!!!)

I've heard of this saying also,but
The CD was bought in the store, sealed off and with a serial number on the
booklet, as with my Fritz CD.
That's why I'm surprised. I contacted the store and Chessbase, but I haven't
heard anything yet....

I wonder if this is because you are short of RAM and Shredder is getting
swapped out to disk? If it was thinking for a couple of minutes, a second
or so to pull Shredder back into memory wouldn't be significant but, if it
only has a couple of seconds to think, most of its time would be gone
before it had chance to analyze.

I would guess that the reason it's hitting Shredder rather than Fritz is
that you're running Fritz and using Shredder as a secondary engine; if you
do it the other way round, you'll probably find that Shredder wins all the
games.

I use the regular shredder 9, but when I installed it on my PC it seemes to
have taken over the Fritz8 I installed before (when I select Fr8 now I get
the Shr9 intro page).
When I install Shr9 first and then Fr8 and play a game, it shows the same
results with Fr8 being so much better.
On the internet Shredder9 is also awfull with little time per move against
other computers, even when I uninstall Fr8.
