This is interesting. Of course, this is different from the Leiden game today in that black actually has chances in C97/99--it's just that Rybka doesn't play the closed Ruy Lopez very well (the win in Mexico was due to simply having a better position out of book, I think). In Leiden today, Rybka had a position out of the opening as black that not only does the engine not play very well, but also simply gives a struggle for a draw, a struggle in which Rybka did not succeed.
In Mexico, Rybka had +1 in the Ruy Lopez. Two wins and one loss.
EDIT Actually, Rybka had two losses also in the Ruy Lopez. I try hard to forget Mexico, and I seem to be succeeding, finally! :-)
EDIT Actually, Rybka had two losses also in the Ruy Lopez. I try hard to forget Mexico, and I seem to be succeeding, finally! :-)
In being critical, I have primarily referred to Rybka playing the Ruy Lopez with black--it has not gotten anything in any of those games, and I seriously wonder if this opening is even playable at the >3000 level. If it is, Rybka doesn't know how to create good positions with it for black. Also, I really don't think that you can call Mexico game 4 a "win"--we had the case where Rybka did not know how to convert the winning position. I know that's not the book's fault, but if the program isn't able to win won positions in a particular opening, it's probably better to go for openings that result in middlegames with different won positions (for Rybka this means "nearly all openings" :-)); we know that Rybka has very low chances of getting a middlegame or endgame with a won position on the black side of C90-99, and we also know that many programs are able to play the white side of this extremely well. Of course, if Rybka is white and black so blesses her with playing the closed Ruy Lopez, then so be it--this seems to give white a lasting advantage through the middlegame, and Rybka should be taught to convert this advantage.
Rybka did win both game 2 and game 8 in the Ruy Lopez. It would have been more logical if she had won game 4 instead of game 8, of course.
Yes, I'm sorry--you're quite right on that--I had forgotten that game 8 was a Ruy Lopez. But this still leads to the same point: given the fact that Rybka and Zappa are about the same strength, and that it is impossible for black to get a decent advantage in C90-99 without noticeably bad moves by white, shouldn't black scrap that defense against opponents around 3000 elo or more? As much as we like to discount Junior, it still must be true that Junior on a 16-way plays with 3000 strength.

" it still must be true that Junior on a 16-way plays with 3000 strength."
I wouldn't be sure about that. In the CCRL Deep Junior 10 with 4 CPU has 2913, so doubling the number of processors twice has to bring 87 points, or 43,5 elo per doubling. bur deep junior 10 2 CPU has 2900, which means 13 elo going from 2 to 4 processors. so why should it be much better for 4 to 8 or 8 to 16 CPU?

I strongly disagree that Deep Junior 10 2 CPU has 2900 elo, in spite of the CCRL list. 2913 for 4 CPU is about correct.
I should not comment too concretely, but I can make one general comment: One part of our job as book-makers is to challenge the usual wisdom and prove it wrong :-)
Amen.
Rybka beats Naum with the black pieces.

She certainly showed her class there.
Two more rounds to go tomorrow, we're currently in 2nd place, but hopefully Rybka will beat LearningLemming - who Bob managed to let beat crafty :) Anything can happen in a 6 round tournament though!

Two more rounds to go tomorrow, we're currently in 2nd place, but hopefully Rybka will beat LearningLemming - who Bob managed to let beat crafty :) Anything can happen in a 6 round tournament though!

Congratulations on winning the Minnows and The Sharks tournaments today!
Congratulations on winning two tournaments over 1 weekend!!!! By the way what was Crafty running on?
Bob said crafty was on "8 x 2.33 ghz" - I am not sure if that is AMD or Intel though. Probably I could have chosen a little deeper book in that game, 15. Nb3 was Rybka's first move out of book, perhaps instead 15. d5! locking the center followed by the Knight going to g3 via f1 would have been a better plan, maybe then Rybka would have 6/6 as she deserved. For the first three games I was running with a 0.5mb book but after game 3 I beefed it up a bit to a whopping 1.9mb. I forgot that Bob has terabytes of book! (Like Nelson :)
christ you are realy into it, i did not know when i posted you saying thanks,please forgive my ignorance when i posted earlier.
What a nice game vs. Naum! It doesn't seem quite right that black wins from such a symmetrical position, and probably white made some inaccuracies, but that Nd7-f8-g6-h4 sequence is beautiful! Them horsies are strong...
It doesn't seem quite right that black wins from such a symmetrical positionI agree Dagh .. if this was a freestyle I would have expected 1/2-1/2. A friend of mine who does a lot of engine-engine testing (I don't own Naum myself) told me that he had good black stats for Naum-Rybka in the French so I thought it was worth a try. I didn't actually watch the whole game due to other commitments, but it looks from the log that Rybka saw she could win the white f-pawn with her Knight aeons back by pushing her black h-pawn to restrict Naum on the K-side. Awesome searching? The nice thing about Rybka is that she is so strong if you can get her to a playable middlegame she'll often "do the business" (unless you underbook by one move as I did in the crafty game :))
I felt a little sorry for Alex in this tournament, in Round 1 he had some technical difficulties, he said he had a old version of Naum (perhaps a "Loser's Chess" variant?) in his winboard path and this was the result:

Couple that to the fact that for some reason the colonials didn't put their clocks back in synch with their masters in Europe over the weekend meant that Alex almost missed round 5 as he is currently in Serbia and didn't get the message.
Perhaps the whole world should adopt the approach of the Canadian province of Saskatchewan and stay on central time all year around :)
Thanks Nick for running everything and keeping us updated. :)

Great job Nick. I wouldn't worry about Nick not having Jeroen's book ... he has his own very good creation and knows what Rybka plays well ;). Two wins in one week ... not bad at all.
Hehe thanks again Majd. Really though, a good book shouldn't lose easily, a GREAT book is that PLUS some new killer variations that blow away the competition. Mine is in the former category and Jeroen/Dagh's in the latter.

Hi Vas
If your GUI has both ctg and polyglot books import/export (with preservation of the "weights" of the moves), it will be a real kind of heaven's gift for anyone liking to experiment with openings.
I preorder it at any price (well almost :-) )

I think there's "only" a import option for .ctg books planned.
Convekta is handling this and I'm not sure what exactly is going to make it into the GUI.
Clearly, import + export with all data preserved is the best solution. You'll lose a lot of guys who might potentially switch over if any of these three properties are missing.

Hi Steinar,
From Vas' response it looks like the Rybka gui will be able to connect to ICC, in which case I would go that route, but until then I'd be interested to know if it was possible to turn a *.ctg format book into a polyglot http://wbec-ridderkerk.nl/html/details/PolyGlot.html book. This would be useful as *.ctg has one (and only one) nice feature that polyglot books do not have (and polyglot books have many nice features not present in *.ctg).
Best regards.

I'm not sure the Rybka GUI (at least 1.0) will be able to connect to ICC, but it will be able to convert CTG books into its own native (and CA-native) format.
Also I think we'll allow to 'decompose' the book into several games in a PGN file. As far as I understood from the link, Polyglot can compile its book from PGN, so there is a possibility of getting a CTG book converted into Polyglot format.

Thanks, I keep all my stuff in pgn files anyway so it's not an issue to me personally if I use them to build *.ctg or polyglot, or any other format books. But for those who have locked themselves into the *.ctg format ... this translator will be very valuable indeed :)
Best regards.

What feature? :-)
/* Steinar */
/* Steinar */
Steinar, the feature is "Add Priority Analysis" .. but in a "special" way. This special way is described by Marc Lacrosse here ->
http://users.skynet.be/mlcc/chessbazaar/tips002.html
In summary, if you code a PGN file in the following way:
1. e4! c5 2. Nf3! d6 3. d4! ... etc
and then use chessbase "Add Priority Analysis" to add this game to your book, the probabilities of every possible move OTHER than the ones with the ! will go to zero. Chessbase folks quaintly call this "turning the moves red", where red indicates "don't play this move".
The possibilities of this feature are many, for example:
1. Someone beats you on a chess server with a particular game and you don't know how to fix it. Well, you can take that game and automagically code the winning moves with a ! , add the game to an existing well rounded book and hey presto you can play that game on the server to see if anyone can refute it. This is how the 24 ... Rxa3 game was found that momentarily refutes the Rh3 that Rybka beat Hiarcs with at Leiden (see this thread: http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=2509#fp .
2. Others :)
Of course all lines are able to be fixed eventually, I think. But you can have a lot of fun with this feature :) If I could do this with Polyglot books my computer chess life would be complete!
For about a week anyway :)

But this is not a feature of the format, right? It's a feature of ChessBase itself?
/* Steinar */
/* Steinar */
That's correct. It's not instrinsically built into the format of the book. CB provide a way to automatically change the probability to zero of all lines in a book that clash with the line that you want it to play. There is no utility to do this with Polyglot books. You can hand tune them with scid of course, but this takes a long time to do.
I take back the statement that "add priority analysis" cannot be done with a single game with polyglot books.
It seems that the polyglot merge-book function is asymmetrical. So if one builds a one-game book called priority.bin and merges this with one's normal book like this:
polyglot merge-book -in1 priority.bin -in2 normal-book.bin -out test-this-line-book.bin
Then this achieves what I want (I just looked inside the test-this-line-book.bin book with scid and indeed there are no other moves in the line in question).
This has been a good discussion for me at least - so thanks :)

Indeed this works nicely.
This was coded by Fabien after dozens of mail exchanges we had at summer/autumn 2005.
This feature is also extremely useful for complementing the fact that PG-scid allows to modify the weight of existing moves in a PG book but does not offer to add new moves to an already existing one.
IMHO Polyglot is the most stunning contribution by F. Letouzey to our CC community.
... no, I do not ommit Fruit when I say that...
At least Polyglot publication had no negative side effect ...

Yes Polyglot is seriously underrated by the engine v. engine community, hardly surprising though as most public engine v. engine games are played on the playchess server, and being a chessbase server naturally folks will use *.ctg. The other thing I like about Polyglot is the size of the books it produces, they seem to be in the order of 1/10th to 1/20th the size of their chessbase counterparts, but made from the same games to the same game length .. I'm not sure how this is achieved .. better compression?
I've been using your technique of running Polyglot books on the playchess server to good effect, book learning with this setup can also be achieved by front ending the Polyglot book with a small *.ctg made solely with "add priority analysis" lines from some very good games. That way if your unattended engine gets drawn (or forbid) beaten (usually by an h3 or b3 merchant) then the book can switch to an alternate line.
One question if I may, is there a list somewhere of the Polyglot parameters? (Some might call these parameters "heuristics" I guess). I mean I know of:
-only_white
-only_black
-min_games
-min_score
but are there any other good ones to experiment with?
Hmm - this looks like a loaded comment.
PS. Thanks for collaborating with Fabien on the asymmetry in the merge-book function!
PPS. Vas - I gave Charles all my Polyglot secrets so I am expecting some good openings from the engine "Telepath" now :)

PS. Thanks for collaborating with Fabien on the asymmetry in the merge-book function!
PPS. Vas - I gave Charles all my Polyglot secrets so I am expecting some good openings from the engine "Telepath" now :)
Being grouped with the unwashed, knuckle dragging h3 clan is really harsh...
I've heard that there are some folks who even believe b3 to be a valid opening :) IIRC (too lazy to check) for some unknown reason Jeroen did not mark 1. b3 with zero probability in rybkaii.ctg? Your b3 seems to be catching on though, I have seen a few other accounts playing openings based on your games and doing very well indeed. There does seem to be an over-preponderance of ex-Soviet people playing 1. h3 on Playchess, I'm not sure what that says - if anything. However I was reliably informed by one of them that "Russians never pay for software" .. so maybe knuckle dragging is a behaviour we could see exhibited by such rationalists? I cannot believe that such a claim could be true. The interesting thing is they don't seem to mind spending some serious wedge on top flight hardware and vapo coolers!
There are some very wealthy people in the former Warsaw Pact countries now. As we've seen, many of them haven't really come to terms with intellectual property rights, so seeing a bootlegged copy of Rybka running on a seriously expensive rig would not be too surprising.
When I was in Prague a few years ago, I noticed that the Hilton I was staying at was running Chinese bootlegged versions of all the Microsoft favorites (Windows and Office). When I mentioned this to the manager, he couldn't understand why he should even consider paying thousands of dollars for the real thing when the bootlegged copies worked just as well. Of course Hilton Corporate saw things a little differently (I owned a fair amount of their stock at the time).
As far as 1. b3 is concerned, I'm still waiting for your new line. As I recall, it looked like a handicap game by the time my engine came out of book. :-)
Regards,
Alan

> One question if I may, is there a list somewhere of the Polyglot parameters? (Some might call these parameters "heuristics" I guess). I mean I know of:

The "readme" file has all flags for book making described (as far as I know there is no undocumented feature for book-making).
Two flags you did not mention are :
- max-ply : this is important because default value is infinite and you do not always wish to follow known games for too long
- uniform : a simple way to enforce equal frequency for different candidate moves you wish to test in a forced-lines book
For what regards myself I most often merge at least six elementary books for building a global book.

Ok thanks Marc .. I was wondering whether I had missed anything in a previous version of a Polyglot readme, the reason I thought that is highlighted by the first occurrence of the string "-min-score" in the current 1.4 readme, I quote:
""-min-game 1" is characteristic for user books. All moves are supposed
to be safe so there is no reason to filter them with other heuristics.
This shows how min-score can actually be different for white and black
(as with multiple books). I don't use "max-ply" because "min-game"
default value of 3 will limit depth somewhat. You are of course free
to use it."
I come from the school of documentation writers that says "first list out the parameters explicity defining what each one does and only then show usage of them in examples". What we see above is an example introducing a parameter, so my natural mindset was to think that there must be a list of these parameters somewhere, perhaps in a previous readme. But Fabien, being his ever efficient self, has dispensed with such duplication!

Hi Nick
Do type "best C" on ICC and you will see that my bot (Tweetie) made some progress.
By the way its book is a not-that-small Polyglot one :170 MB.

Very nice indeed. I can see that BigMomma will need to worry about you! Here is something for you to aim for:
