CCT 10. January 26-27, 2008

Introduction

Official Website: http://www.cctchess.com
Site: The Internet Chess Club (ICC)
Tournament Director: Peter Skinner
Date: January 26-27, 2008.
Time controls: 50 + 3
Rounds: 7 Round Swiss.

With 39 participants, including many of the strongest engines, this tournament promises to be very interesting. And with only 7 rounds, a single mistake can be enough to eliminate an engine in the race for first place.

Participants

Some of the more notable participants are Rybka, Zappa, Hiarcs, Junior and Naum.

Rybka is the current CCT champion after winning CCT9 last year. With Rybka leading all rating lists it is the favourite to win the tournament.

Junior hasn't participated in recent computer chess events, but the team is always well prepared. Playing on the most powerful computer (16 CPU cores) shouldn't hurt its chances.

Zappa won against Rybka in a 10 game match last year. Anthony Cozzie has come out of retirement once more to produce a new version of Zappa. If he is less than 97.8% retired now anything can happen :)

Hiarcs is the winner of the latest Paderborn tournament. It's always an interesting opponent for Rybka.

Naum should not be underestimated. We can expect Naum 3 beta, which beta testers say has been doing very well against Rybka. Some think that Naum 3 beta may be Rybka's closest competitor.

Thanks for the information Dadi; it seems it will be a very good and interesting small tournament.   

By the way, do you know what Rybka version will play there?

I would expect Vas to use this tournament as a test for a recent development version. But I'm sure Vas or Nick will tell us later today.
Parent - By Vasik Rajlich (Silver) [hu] Date 2008-01-29 01:02
Actually, we used the Paderborn version - the newest version wasn't ready in time and we didn't feel like inviting Mr. Murphy over for tea :)

This should be an easy round for the top engines, but who know? Bugs, book errors, technical problems (especially in the first round) could affect the outcome. And of course unexpected wins by lower rated engines have been a deciding factor in many computer chess tournaments.

> 1 Rybka (1)          : Rascal (20)      


Assuming Left is White, this is already a notable advantage for Rybka - the chance of getting 4 Whites is quite significant now.
Parent - - By Dadi Jonsson (Silver) [is] Date 2008-01-26 09:57
Since there is such a big difference in strength between Rybka and Rascal, colors don't matter much in this game. Therefore I would have seen it as an advantage if Rybka had the black pieces. That would ensure at least 3 Whites in the remaining rounds against the stronger opponents. Even 4 Whites would have been possible.
Parent - - By Permanent Brain (*****) Date 2008-01-26 10:20
Although I am a big fan of Rybka too... Wanting Black rather than White for sophisticated pairing system reasons only, because we are so absolutely sure that Rascal will lose anyway, doesn't sound fair to me. What if the author of Rascal reads here, how would he feel reading this? I don't know this engine but I am sure it can play chess and efforts have been put into it. I think we need to be careful, because... Pride goes before a fall.

Maybe not Rascal, but Naum could be the Nemesis. I see dark clouds on the horizon.
Parent - By Dadi Jonsson (Silver) [is] Date 2008-01-26 10:41

> because we are so absolutely sure that Rascal will lose anyway


I am not absolutely sure about that and therefore I didn't state that in my post. I only think that having white or black cannot be viewed as a deciding factor for a game where there is a great difference in rating/strength between opponents. Rascal certainly can draw or win this game. Upsets happen both in human an engine chess.
Parent - By Permanent Brain (*****) Date 2008-01-27 19:09
Despite all false modesty, I need to say that I was (nearly) right about Naum! :-) But it wasn't difficult to guess.
Parent - - By BB (****) [gb] Date 2008-01-26 10:36
I expect there to be 2 rounds of wide strength disparity [to predict: 5 or 6 of the top 7 win in round 1, and 6 or 7 of the other 12 games are decisive, so Rybka plays the 9th seed or so in round 2], and from this I am led to think your idea of more Whites against strong opposition doesn't really apply. The advantage of getting White in game 1 is that some pairing systems will alternate colours, and so when Rybka faces Naum, Zappa, Fruit, Junior, Hiarcs [just to name the next 5 seeds] in rounds 3-7, it will be more likely to get 3 Whites in these 5 games than if it had started with Black.
Parent - - By Dadi Jonsson (Silver) [is] Date 2008-01-26 11:14
It seems that the ICC pairing system does indeed do a better job of alternating colors than I expected. I checked both CCT8 and CCT9 and in those tournaments Rybka never had the same color in two sequential rounds. Assuming that this will also be the case in this tournament, and if Rybka starts playing against the other top seeds in round 3, then it's better to have White in the first round as you suggested.
Parent - - By Somnus (**) [ca] Date 2008-01-27 07:16
As the TD for the tournament, I am doing pairing manually.

#1 seed in the tournament always gets white in the first round if you look at past events.
Parent - By Dadi Jonsson (Silver) [is] Date 2008-01-27 08:51
Thanks for this information.

> I am doing pairing manually.


I noticed that the pairings seemed much better than I had experienced in ICC tournaments (at least a few years ago), so this explains the difference.

> #1 seed in the tournament always gets white in the first round


OK, so no luck involved here, except being "lucky" enough to be #1, of course :) I had assumed that the color on board 1 was determined by lot, as is common in international tournaments.
Parent - By Harvey Williamson (*****) Date 2008-01-27 08:57
Hiarcs also started with White in round 1 but has 2 blacks in a row rounds 4 and 5 - but I am not complaining.
Parent - By turbojuice1122 (Gold) [us] Date 2008-01-28 02:52
But which would be better?  A win over Zappa (more likely with the white pieces), or not having lost to Hiarcs (which would have been more likely with the white pieces)?  With the way things came out, now Harvey is going to be displaying "ugly pictures of dead fish" all of the web site from here until Rybka finally gets a few good, convincing wins over Hiarcs. :-)

Rybka’s last book move was 10. d5 with evaluation +0.37 for white.   Rascal’s first move out of book was the interesting 9 … b6.  In fact there was a good 0-1 in this line in 2004 between two shredder’s on Playchess but I didn’t think that game was relevant here.

Some info:

Software: Rybka 232m14-rmp.  2GB hash table
Hardware: QX9650 @ 4.2 (water cooled).  Crucial PC8500 ram 4-4-4-12@508
Books and interface: Various.  In round one we used a small CTG book.  The new Chess Assistant can directly read CTG now!  It respects red and green moves etc, round 1 was a test of this technology, and it performed admirably.

Jeroen’s own book is not being used for this tournament, Jeroen is at Corus this weekend and is also working on RybkaIII.ctg, book duties have been left to me for this CCT (gulp!)

Later on when we play some of the big boys I will be using Winboard + Polyglot + a Polyglot book. 

Hiarcs had a nice book win in round one using one of my own lines () and Zappa as black has played a dubious move ( 4 … cxd4) against Tinker but will no doubt come good!

Junior won with the black pieces, possibly with a novelty on move 7, I need to check the game.

Naum is having ADSL connection problems and is not playing, he will try to show up for round three, if that happens he'll miss two rounds.

Funny, I noticed that last 5 moves before mate were dificult for Rybka to find.
73. Qg2 took a few tens seconds.
Parent - By Dadi Jonsson (Silver) [is] Date 2008-01-26 13:38

Parent - By Uri Blass (*****) [il] Date 2008-01-26 14:41
No

The fact that rybka used her time does not mean that the moves were difficult for her to find.
Rybka simply used her time and
I am sure that rybka could play them faster in case that the game was bullet game.

Rybka with the black pieces beats Crash Test Dummy (CTD) in round 2.  CTD is written by the author of The Baron (Richard Pijl) and I’m informed that it’s an entirely different engine to said previous work.

The good news is, we can see the pairings before the games start and adjust the opening book accordingly.

After some sub-optimal opening moves from black a drawish position was reached.  Rybka’s last book move was 10 … Na6 with a score of +0.00, CTD’s last book move was 9. 0-0.   Rybka then went to work on her usual middlegame crush, with moves like 20 … c3! creating a white isolani followed by the inaccurate rook exchange from CTD.   Maybe the game could have been drawn, but in any case Rybka demolished her opponent in short order.  

This game was again played with the Chess Assistant Interface with a CTG book.   Things will probably start getting a little tougher now, it looks like Zappa with the white pieces is being given a hard time by crafty as well, it's an interesting game :)

Seems like Junior will lose first half-point.
The first loss among big four: Rybka, Zappa, Hiarcs, Junior.

Next round will be the last one where the big four can meet not strong opponent.
After this all games will be tough.

Rybka with the white pieces gets a draw with Ikarus in round 3.  This 1 … e5 response to 1. e4 continues to cause problems.  Ikarus’ last book move was 10 … dxe4 and Rybkas was 13. Bf4, where she came out with a +0.49 score.   Despite being +2 eval up at one stage, the position turned out not to be a won endgame after all, Ikarus played all the correct defensive moves for the ½ point. 

Hiarcs (convincingly) and Zappa (Anthony admitted luckily) won their games and will meet in round 4, that promises to be a great game.   We will play LearningLemming.

I can not understand how a program as Ikarus, with 2500 of elo, can make a game draw to Rybka.
The round 4, it took much win. Not Rybka demonstrates its potential for 3100 elo.
Parent - - By turbojuice1122 (Gold) [us] Date 2008-01-26 21:03
Ikarus is far, far higher than 2500 elo.  It's at least 2700 elo, and if it was to be released for testing by, say, CEGT, I would guess it would be somewhere in the 2700-2750 range.
Parent - - By miguel angel (*) Date 2008-01-26 23:58
yes, but Rybka, is far, far higher than 2700 elo. Would have to win all chess programs with scores below those of 3000 elo. And draw or have trouble with chess programs above 3000 elo.
Parent - By turbojuice1122 (Gold) [us] Date 2008-01-27 04:30
Well, it just doesn't work that way, especially at this level of competition.  Chess players do occasionally lose to people rated 400 points below them.  They even more often get draws with players 400 points below them.  In one of these tournaments, it should not be surprising when it happens occasionally, as it does.

I wonder if a more aggressive Rybka could have crushed Ikarus.
Parent - - By garyf919 (**) [us] Date 2008-01-27 01:19
I have often wondered this same thing. I think that Rybka seems to try to play perfect chess, but
there seems to be a factor of being aggesive and taking some risks that Rybka lacks. I've noticed
that by just looking at the number of moves Rybka takes to beat her opponents that she always takes
many moves than say Zappa or Hiarcs. This to me, smacks of trying to be "too perfect" or taking no
risks whatever to win a game. Or maybe the code of Winfinder should somehow be incorperated
into the search (as I stated much earlier).

Yes, I have noticed this too. Engines like Loop or Toga seem to have a great success beating weaker opponents, and they do it in fewer moves than Rybka. My theory is that these engines are more aggressive, while Rybka is more solid. Rybka plays expecting the moves from another Rybka, so she doesn't enter into positions that another Rybka would take advantage. This strategy doesn't seem to work that well against weaker non-Rybka opposition.
Parent - By JhorAVi (***) [ph] Date 2008-01-27 10:44
Rybkas 3100 rating is not based on just a single game. Rybkas 3100 rating will show when you try say a ten game match between it and Ikaurus. Probably Ikaurus will draw a single game then loose the rest of nine.

Material is enough to win for either side. For example:

You mention that the new CA can access CTG now is this CA 9.1 or something to be release soon? (and if so do we know a date)...

thanks

I don't have dates, you'll have to ask Victor about that.   It's not 100% yet, for instance I don't believe that the CA support respects weights in the ctg book yet.  Still, it looks very promising.

Thanks for the reply... I'll message Victor

I think the next Convekta program that will be able to access ctg books will be the new GUI for Rybka. At the moment it doesn't work 100% perfectly since the weights aren't always right, but anything else works quite good.

Thanks for the info.

Round 3:  Rybka - Ikarus : 1/2 - 1/2
Parent - By Nick (*****) [gb] Date 2008-01-26 19:36
Rybka with the black pieces beats LearningLemming.  I didn’t consider Qa4 playable so was out of book after that.  Zappa beat Hiarcs and I do so hope we get to play Zappa with the white pieces tomorrow, Zappa is running on the machine of Clemens Keck, the Cluster Toga bookmaker, so if we can win, it will be (as Vas says) a double victory (in a way).
