a.. No underpromotions
b.. Improper handling of mating sequences
c.. Issues in variation display
d.. Various quirks in analysis display
e.. No EGTB access code
f.. 50 move repetition problem
g.. Will frequently lose on time under Arena
h.. No endgame knowledge
i.. Limited user options
j.. Not completely stable
k.. Not thoroughly tested

You would think that it could do these things as part of the first release,
especially for $40. Sheesh.

If you read closely you will see that the $40 gets you upgrades to
1.1 and 1.2 as well. Still, it would be nice if the web page made
it clear how 1.0 preview differs from 1.0 beta. I think the only
difference is that there are some more UCI options (e.g. hash table
size). Perhaps some bugs have been fixed as well.

As someone else mentioned, if you are just getting into chess,
Chessmaster 9k, 10k or Fritz would be a better purchase. Lately
I've become quite fond of the Shredder 9 interface but it's probably
suitable to more serious enthusiasts.

...and it will demolish the chess world as we know it. It is not only the
strongest chess engine in the world, it will be released without copy
protection. Everyone who wants a copy will probably be able to get one for
free, if they wish, if they're a little bit patient. Only those who want it
quickly, at the first, will have to pay for a copy. So it will be quickly
distributed worldwide to all chess players who own a computer. Nobody will
buy other chess engines anymore. Established chess companies will go out of
business. It is a revolution!

Now, let me speculate a bit further, into the darker side... It is a large
engine package, about 2.5 MB. Most chess engines are small, less then 0.5
MB. Who can say exactly what is built into the 2.5 MB "engine". We therefore
are trusting our computers to this software, and must hope that the
originator is not intending to use our computers for ulterior motives. I
don't think this is paranoid. There are many different kinds of people in
the world, and it is certainly possible to build some hidden code into a 2.5
MB executable. Your guess is as good as mine, but somebody will technical
expertise should take a very good look at it for a trojan. Of course most
people won't even consider such a possibility, so there will be no way to
stop it even if it contains a trojan. It has already gone too far. However I
expect it will be clean software, and this is only speculation.

There are only two games done on my computer (AMD64@2Ghz 32-bit OS(Win2k))
against Ruffian (there once was a hype too, as Ruffian has been new) result:
Rybka 0.5-1.5:
(sorry for the %xyz comments but I thought some of you are interested in these

Don't be absurd. Rybka is, at best, marginally stronger than the other
engines out there. Paying for Fritz gets you a GUI, a reasonable
database, various training and analysis features and an engine that's only
fractionally weaker than Rybka and stronger than practically every human
on the planet. Sounds like much better value for money than Rybka.

Just like every other piece of software you run, even open source. See,
for example, Ken Thompson's ``Reflections on Trusting Trust'',

http://www.acm.org/classics/sep95/

It's much more likely to be inefficient coding. Who would bother to write
a world-class chess engine as a vector for a Trojan when they could use
one of hundreds of exploits in Windows to propagate their program further,
faster and more easily?

Besides, your argument doesn't hold water. You're saying that 2.5Mb is
too big for a chess engine because most are around 0.5Mb. Well, the
remaining 2Mb is too big for a trojan. What on earth would you put in 2Mb
worth of trojan?

Perhaps for newbies, but I already have all of those things, so I'm only
interested in engine strength. It also relates to how you use chess
software. I only use it for long analysis in infinite mode like most
correspondence chess players.

Tests at the links above say that Rybka 1.0 32-bit is about 30-40 Elo points
stronger than Fritz 9 at 40 moves in 40 minutes time control. For those who
have 64-bit operating systems, the Rybka 64-bit version runs 60% faster than
the 32-bit version, so is considerably stronger. Clearly Rybka 1.0 also
beats Fruit 2.2.1 and Shredder 9.1, so it appears to be the top dog at
present.

Still waiting in the wings is Zappa which could trump all of them, and
perhaps very soon, within a month, maybe less. It depends on when or whether
the Zappa author decides to release his latest version and perhaps go
commercial. Like I said, a chess software revolution is upon us. No more
status quo. The old heads have already fallen, and the new ones are
competing fast & furious!

Yes but the same tests indicate that Deep Shredder 8 is about 20 points
stronger than Fritz 9. Like I said, Rybka is marginally stronger than the
other engines out there. Claims that it's some kind of amazing revolution
are way over the mark.

http://kd.lab.nig.ac.jp/chess/cegt/rating-table-all-300-shifted.shtml

As you imply, though, it's very interesting to see a crop of amateur
engines (Fruit, Zappa, Rybka) suddenly appear at the same sort of strength
as the top commercial engines.

This kind of "black box" evaluation can
hardly support serious claims regarding a
revolution in the making... Unless the
authors and developers of these programs
are willing to talk about the _specific_
nuts and bolts comprising the _stuff_ of
the "revolution", this poster, at least,
will remain highly sceptical! Evolution,
instead? 8 >)

1) Newcomer Rybka is very good, okay.
But after 50 slow games (40 moves in 40 min)
against TOGA II 1.1 that "demolish-the-chess-world-program" Rybka
is just up a half point: 25,5 : 24,5.

And TOGA II is freeware!!
[ www.uciengines.de ]

2) Your conspiracy theory - "the darker side" of that 2,5MB program:
Doesn't any shareware or freeware or any other program have
that option of a "darker side"?

Thanks for the link. Wish I could read German better! They give:

Rybka 1.0 Beta 32-bit gegen

28,0-22,0 (56 %) vs Fritz 9
25,5-24,5 (51 %) vs Toga II 1.1
34,0-16,0 (68 %) vs Shredder 9 UCI !!
36,0-14,0 (72 %) vs Hiarcs 9

Yes, Toga II 1.1 is an excellent free engine, and an improvement on its
mentor, the free engine Fruit 2.1. The commercial Fruit 2.2.1 may be
slightly better.

Also note what Rybka 1.0 Beta does to poor Shredder 9 UCI which was #1 on
the last SSDF list, and it also beats the recently released Fritz 9.

Here's the same information in English on the original website:

which includes several relevant links.

These tests above use 40 moves in 40 minutes time control, intermediate
between blitz and the traditional slow time control of 40 moves in 2 hours
(or 2 1/2 hours). SSDF does that one, and would expect they'll start testing
Rybka 1.0 after its December 11 release.
