Subject: Best engine for analysis?
|
I am hesitating between buying Fritz 10 or Rybka for my 4-processor
computer. I use chess programs mostly for analysis, and most of the time
for short times (say less than a minute). Which engine will give the
most accurate analysis in such cases? I know Rybka is stronger at normal
time limits, but is it more likely to find the best move?
Also can I use Rybka as an engine with the Fritz 9 interface? If so
would it use the multiple processors although my version of Fritz 9 is
not multiprocessor?
If not, is the Rybka interface (almost) as good as the Fritz interface?

The last engines i had bought were shredder 7 and chess tiger 15.
Shredder 7.04 according to many is the last really aggressive engine
while CT in suicidal mode produces games anything else but boring. I
was thinking about hiarcs 10/11 due to its fame of being closer to
humans/positional but rybka seemed to had surpassed it in that field
and so i went on and got myself rybka. I may also consider CT2007 in
the future if it still has an interesting style.
I haven't let rybka run overnight yet, but i'd like to know if anybody
knows how deep is the accuracy of the variation it examines? There are
engines that they can give pretty good moves for the first couple of
them but then deep down the variation they mess up the output.

Fritz 10 has special features for training and analysis that are only
available through it's UI.
Rybka is said to make stronger moves from move 1, and has a generally
different style from Fritz.
Generally, you have to have a UI to go with Rybka and it works perfectly
fine in the Fritz UI. I have, and I suspect many use both programs, and
focus on areas where there is a significant difference of opinion
between the two programs.
Rybka tends to have the best results at short time intervals. But if
you are truly doing analysis, that is only really good for quick blunder
checking, and you can generally use any modern engine for that,
including very good free ones like fruit. The real benefit of using
any one specific program comes from depth.
That said, if you use engines, you have fritz, Rybka is really too
cheap, not to put into your arsenal.

One minute is not enough time for analysis of a game, you are just wasting
your time, you should know better than that Henri !

I would not hesitate - Rybka is the best by quite a gin.

I think Rybka is better than the rest at any time control.

Yes.

Rybka does not come with any interface at all. It is a command line
program supporting the UCI protocol. As such is must be used in an
interface.
Rybka does directly use an opening book - the interface must make the
opening moves from the opening book. The best opening book is designed
for the Fritz interface, so you would have an ideal combination.
Rybka is pretty cheap and I have found the support far better than I
found with Chessbase when I had problems with Pocket Fritz 2 following
their changes to server/database they host to look up games. I don't
have a great opinion of Chessbase.

Well, at least he was only second to Shredder (a full point behind) in
Blitz Chess at the last World Computer Chess Championship.

As far as engines goes, Rybka is pretty cheap and it is the best, bar none.
Further, it will work fine with Fritz 9. It works plenty well at short time
control; especially if you have a dual-core, quad-core or mutliple CPU machine
as you indicated. Rybka is all I use until Chessbase puts out something that
beats it [and then I probably still won't use anything else as I am not that
good!].

Henri:
I would be tempted to say that Rybka is the strongest practical engine but
maybe not the best one for analysis.
It has some known bugs (limits in underpromotion, does not always recognise
zugszwang ...)
See the Rybka forum for more on that.
Myself I prefer "balanced engines such as (Deep)Fritz (9 or 10) or (Deep)
Shredder (9 or 10) for analyzing games, studies...

Thanks everyone for useful rfeplies.
I guess I will get Rybka to use with Fritz 9 on my Quad computer, and
maybe gt fritz 10 multi-processor later.
