Is it at all possible to set up the engine (I tested at fritz elo 1620) so
it should play more evenly?
When set at 1620, it plays many moves at level 2000 and eventually to reach
the average 1620 fritz 9 makes some stupid move losing its pown in a very
visible way.

His Fritz beats my Ivan as black and white .
So he dummied down his Fritz to see about what ELO my Ivan is...The box
says I,800 ELO well we figure it out to be I,700 ELO .....At that ELO
Ivan can win and sometimes it loses but it is always seems like a close
game .....

Playing "poorly" is very very difficult to do "well". There has been
some speculation how to do this, and there was likely to be work done on
this soon. But, I suspect that there has been massive work to catch up
with Rybka by all of the leading engine teams recently, so that "poor"
play is currently taking a back seat.

I didn't have that problem with Fritz 8 (or perhaps I'm too weak to
notice it). Were you using handicap mode?

I never used handicap mode. I used Friend mode a few times and now I play
only rated games. Fritz shows my elo now is about 1700.

That doesn't sound right. In Fritz 8, at least, `rated games' means
that Fritz plays at full strength and the rating just measures your
performance. But you were talking about getting Fritz to play at
lower levels. Is this something that has changed between versions 8
and 9 or are you mistaken about which mode you're in?

You can set the ELO strength down to 1600 in Fritz 8 and play a
rated game.

That's still a whopping 270 elo stronger than you Lohner!
Maybe if you set it at the minimum, drop it a few times, and put batteries
that are almost dead, you can get it's strength down.

My friend played his Fritz 9 vs Rybka in I7 , 5 minute blitz games and
Fritz went one and sixteen ......ouch....
But on longer time controls 25 min game they drew and a 90 min game
Fritz won.....
Why can Fritz draw and win a longer thinking game and get dominated at
the short game ?

My guess is that Rybka makes more shortcuts in its analysis. This
means that, if there is a good move, Rybka will be more likely to
find it more quickly. On the other hand, if the move has a subtle
refutation, Fritz is more likely to find it, given enough time.
But that's just a guess.
Dave.

Obviously it's making more "shortcuts" (called pruning) idiot. That's like
saying the car is going faster because the wheels are making more rotations
per minute. You're not actually saying anything.
And a guess from a know-nothing patzer like Richerboy here has about as much
value as the psychotic ramblings of a schizophreniac drunk.

I noticed that Rybka tends to come up with the correct move much quicker
than Fritz, even though it's crunching less n/s. In my bench testing, Rybka
even amazingly utilized gamesmanship to eek out wins in drawish positions
against Fritz. It would jockey with the position for awhile and make it's
lever move when Fritz was dangerously low on time.
I've always said that a chess program should be designed by a strong chess
player. Vasik Rajlich is just that, he's an IM. Even his wife is a 2450 FIDE
rated player and also works on the Rybka project.

Um. I seem to have missed that by selecting `Blitz game' when I
thought I was selecting `Rated game'. My mind boggles.
Thanks.
