New domain names for FICGS apps
Quite good news for FICGS !
As you may know, .app domains are available for a few days... I was not able to take the very best domain names (chess.app & ajedrez.app), but very good ones anyway. I hope more players will come from Google to the following:
playchess.app (english)
jugarajedrez.app (spanish)
xadrez.app (portuguese)
echecs.app (french)
These ones should be online with the Chess Trainer app within a few days... By the way I also bought:
pokerholdem.app
playgogames.app
It is really hard to find good keywords in english for the Go game... Maybe baduk.app & weiqi.app would have been better but not so sure.

Monte Carlo Analysis
I first came across Monte Carlo Analysis some years ago when i bought Fritz 12, which was rebranded as Rybka 4 and packaged with said engine. Back then the analysis mode was only usable with the Rybka engines, but more recently, now that Rybka author Vasik Rajlich is writing the engines for Fritz (since F15), those engines also work in MCA mode.
I don't know what's changed between Fritz 12 and Fritz 16, but i suspect only F16, F15 and older Rybka engines will work with MCA...

Rybka banned from ICGA
Clone or not clone, I'm not sure if this question is worth something in computer chess but ICGA did it: Rybka was banned and stripped of titles...
I just partly read RybkaInvestigation document, a few points are particularly ridiculous (like 2.2 "Sudden Strength Increase"), I have no idea on the other ones and I'm not sure if this is really important in the real world.
Finally, the punishment:
- to strip Rajlich of all ICGA Tournament Titles and,
- force the return of trophies and prize funds to the ICGA and,
- ban his programs from future competitions until he can satisfy the ICGA that they are no longer derivatives and that he has satisfied the conditions of any other penalties the ICGA imposes.
- encourage other tournaments (Leiden, Paderborn, CCT, TACCL, etc.) to disallow the entry of Rybka until it is proven “clean”.

WBCCC Round 3 links and more
Here are the links for Round 3. Plus I have a quick announcement. I have talked to Garvin and I'm in the running to consider adding a 2nd tournament to the WBCCC. Probably called the WBCCC Inv. -> Invitational. This will be more of the standard style of blitz tournament. Something like 14d+1d per move, I don't want to set exact time control yet, I will probably open this discussion up after WBCCC 1 is over. What details I will give is this. What over the prize is next year will split with the other tournament plus a plaque to the winner. My hope is to have another drawing card for the WBCCC and I know this will probably bring more top players in.
Anyway here are the links for you to follow the games you wish to watch this round.
As always we will start at the top boards and work are way down. This time I will just do both of each board at the same time.

WBCCC-New stuff and Round 2 Update
B1-CumnorChessClub (Kevin E.Plant) vs Moz
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21180
Kevin makes an interesting choice here with 2.a4!? vs the Silicon Defense. Not exactly sure what he wanted out of the opening. I can only guess he wanted to mix it up here. Anyway, black equalizes fairly quickly and is better. But after 18.a5! He finds the best way to equalize and both agree to a draw.
B2-jitan vs Loboestepario (Gino Figilo)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21181-
The somewhat unknown Jitan has had a good tournament. And is given his ICCF SM opponent all he can handle. In a game that is still going. Gino is down a pawn, but it appears to be a draw and I would guess the game is about to finish. This was an interesting approach by Gino who gets in b5 and h5 very early in this game. And Jitan plays the most naturally looking sac. 13.Nbxd5! it looked like for a long time Gino was in trouble, but he has found enough resources IMO. A well played game by both players.
B3-Fulcrum2000 vs Mark Eldridge
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21182
This was a nice French game to watch. The novelty move was ..11.Na5, OTB I would like white in this game and I had a feeling that white possibly could have risked an attack, but this game came down to endgame play and White was able to outplay black in the end.
B4-Kamesh vs Stephanie
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21183-
In my opinion this is the most important game the round and it is reaching its fianlly stages. I believe Stephanie to be one of the top players in this event. She has been doing well, but Kam has played the near perfect opening and got her in trouble. If you remember my previous post you remember I talk about Stephanie was in time trouble. Which has not help the cause. The one move I enjoyed the most so far in this game was 36.Ra5!, this was a nice exchange sac. And its given Kam nice pass pawns on the Queen-side. I would guess this game will be over soon. It has been a nice game to watch.
B5-David Evans vs National12
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21184
A battle of the English Countryman here. :) This was the Open Defense of the Ruy. Form the comments I got, it seems that the opening was played about as perfectly as you can get. David posed some problems to Paul(National12), but it ends in a fairly easy draw. One finally note ..10.d4 IMO is a very difficult move to beat.
B6-ppipper vs jitan
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21168-
This is one of the finally 4 games still playing. What looks like to be a draw here. The white black has been dancing for a few moves now, but blacks back rank is weak. That equals a drawish game. :)
This game started out form B90 and so has a ton of theory.
B7-indrajit_sg vs Wayne Lowrance
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21186
I fairly quiet B90 game. I don't think white got much out of the opening. Well played by Wayne here.
B8-tomski1981 vs Uly
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21187
A battle of good friends here. IMO I thought white played the this Queens pawn opening passively. And so we had an early draw at move 26.
B9-Sebastian Boehme vs Schachmatt (Matt O'Brein)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21188-
This is one of the 4 last games. And I have to say its been a good game. We had an interesting Sicilian position. I had thought black was in trouble. But after he tripled up on the d-file. Then got massive exchanges. He looks like its headed toward a draw.
B10-Weirwindle vs donkasand
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21189-
This was a nice positional Sicilian game. Although it ends in a draw. Its a must see game! Watching the drawing combo at the end is very beautiful. It starts with ..27.e4! and you can watch it form there.
B11-Ruben Comes vs Balabachi(William Fuller)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21190
Ruben opened up this rep with 3.h3!? and we ended up with a closed type of Sicilian. But his opponent stayed strong. Though out the game. Even if it looked like Ruben had some pressure. In the finally position.
B12-ralunger (Ramil Germanes) vs keoki010 (George Clement)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21191-
This game saw the Exchange variation in the Queen's gambit. It has a high rate rate. But to Ramil credit he manage to give George a couple of weak pawns in the endgame, but not enough for any real advantage.
B13-Omparakash vs natmaku
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21193-
I would have hoped for more in this game. As I'm a lover of the 6.Bc4 (Sozin) Sicilian. After 14.e5!? this forces unneeded exchanges. After which, the game looked like a draw. And that is how it ended.
B14-deka vs Scott Nichols
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21194
Usually the Exchange Slav is pretty drawish. And this game was no different. But both players did try to mount some kind of advance. Both had good posts on each others side of the board. But a drawish opening is a drawish opening.
B15-TheHug (Jimmy Huggins) vs parmentd
(Daniel Parmet)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21195
I tried my luck in an opening that was not something with e4. And it didn't go as well I had hoped, Daniel was able to get a equal position fairly quickly. In my try at making new theory in a very uncommon line vs the King's Indian Defense.
And finally we have this last game.
B16-SpiderG (Peter Marriott) vs Banned for Life
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21196
This would have promised to be a nice Larson Attack game. By alas Peter timed out in this game as well. I would have loved to seen this attacking game with both sides castled on opposite sides.
Well that would do it for my reports for this round. This was a great round, and the next promises to be great as well. I will post info for the next round after the last game is over with.
Any feedback is welcome!
Jimmy Huggins (2011-04-29 14:45:26)
WBCCC-New stuff and Round 2 Update
The last round was very exciting! And this round has had some great games as well. To speak of there is just 4 games left. Here is the report of the most important games this round.
Starting at the top boards. We have have...
B1-Loboestepario (Gino Figilo) vs CumnorChessClub (Kevin E.Plant)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21163-
This game followed a Catalan. Gino makes ambitious choice to go with 5.Nbd2! I gave this move a ! Not because of its theoretical standing. But because it will lead to a position were white will give up a whole pawn for rapid development. Never the less, black is equal to the task and managers to hold on to the pawn for most of the game and keep the game balanced. With my human eyes, I thought for sure white had an advantage! After move 20.Be4, It looks like white has 2 racking bishops. While black has one black locked in! But in depth analysis shows, that black can hold on. And shows great defensive technique. Down the stretch. Well played by Gino and Kevin. On of my favorite games to follow.
B3-Mark Eldridge vs David Evans
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21165-
David has gotten tested in both his black games in this tournament. And this game was no different. We had another B90 line in this game. And ...8.h5 was used. This is becoming a common line in this tournament. Mark's treatment on the white side was great! I think his future opponents will think twice before trying this line again. At move 22, the game reaches the sharpest point. After move 22.fxe5! I thought that Mark had a chance vs David. But David founds some good moves to exchanges pieces and hold for a draw. The best of which was the combo of ...33.Rf3 and ...36.Rxg3! This was a nice find by him. Great job to David and Mark! I look forward to seeing both these players again.
B4-Stephanie vs Fulcrum2000
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21166-
I would normally just post FICGS member games here. But this maybe one of the top 2 or 3 most important games of this round. In what turns out to be the most exciting game of the round IMO. White has shown that they are quite good in the opening phase. At move 18 they choose 18.b3 which was suggested as being the novelty move. White gets a very strong game and after a king tour to capture the pawn. It looked like a win for sure!, but it seems a mistake was made at move 38. Instead of 38.Qc1!? the move 38.Qe8! seems to be a near winner. I thoughts on why this move was missed is because, White was in time trouble in both games. I have to believe this was a favor. As we speak Stephanie is close to defeat in the other game that I will talk about shortly. I would watch her for the reminded of the tournament. I think they will learn form this experience and be even stronger going future. Well done by both players.
B5-NATIONAL12 vs Kamesh
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21167
Two of my good friends battling here. This was a B90 battle. The novelty move was the straight forward looking 27.h4, but after some exchanges. White has to settled for equality. A good match to follow, the one other note made was this was a line pioneered by Eros Riccio.
B7-Wayne Lowrance vs tomski1981
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21169-
Wayne plays a good line vs the french vs tomski. In fact by the database expert, it was in a 100% win line!! But after the queens come off the board. It burns out to a quiet draw. Wayne has had good opening results, but has yet to get in the winners column. I have faith that Wayne will win a game very soon. Good game to both in this one.
B8-Uly vs indrajit_sg
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21170-
This was a nice game to follow. A french defense was chosen. The point in which it gets interest is the choice to play 19.bxc3!? Which leads to 21.Nh6+!? I loves this sires of moves! 27.Rh3! was also a good move here. But its seems black has just enough resources to hold the balance. ..54.Bxg6! was a good finally touch. Well played by both players.
B9-Balabachi(William Fuller) vs Sebastian Boehme
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21171
What was talked about as a drawish Ruy position. I found to be quite a game with all the early fireworks. I also liked the material imbalance in this game. Sebi has a rep of being very difficult to beat with the black pieces. This helps when you have the Ruy and the Posion pawn line of the Sicilian. As two of your best weapons. ;)
B10-Schachmatt (Matt O'Brein) vs Weirwindle
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21172-
This was an interesting Richter-Rauzer game. 15.Qf4 was the novelty move, Form there it got crazy. 21.Nb3 seems to invite a pawn race. Which in the end white loses. This was a tough game for white. I think he should have been able to hold it. But it was still a good game to follow.
B11-donkasand vs Ruben Comes
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21173
This was a nice positional game by Mike (Donkasand), This was a 6.h3 Sicilian. And we get the usually good defense here. ..7.h5 White gets great positional pressure for the whole game and even gets a pawn, but Ruben wholes for a draw.
B12-natmaku vs ralunger (Ramil Germanes)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21174
This game was a Petroff with 5.Nc3. This kind of move gives white rapid development. Its seems black equalize pretty quickly. And on move 21 a draw was agreed on.
B13-Scott Nichols vs Omprakash
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21175
This was an interesting King's Gambit game. I think Scott didn't study his opponents rep. :) The King's Gambit is Om's specialty. So this was an easy draw for black.
B14-Keoki010 (George Clement) vs deka
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21176-
In this game black returns to his pet line of the Sicilian with 2.a6(Which he played in the last round) I believe this is called the O'Kelly variation. This time around he goes for ..7.Qb6 which looks a little better than ..7.Bb5!? A draw probably should have been possible, but George was able to grid out a win. Well played by both players.
B15-parmetd (Daniel Parmet)vs SpiderG (Peter Marriott)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21177
This was a King Indian by black. And white does a good job of out playing his opponent in this game. Unfortunately it seems Peter has gotten busy in his life. This game was decide by time.
B16-Banned for Life vs TheHug(Jimmy Huggins)
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=21178
I face off against Alan who has the white pieces. And is consider to be one of the best players when playing 1.b3. It was a difficult game for me as I decide before hand to play a dangerous line. Needless to say I lose this game after a few small mistakes on my part. I am founding that all the players in the WBCCC are good, I maybe better off being a commentator lol, but no one would have that.
This was the first set of games.
Here is the 2nd game of the 2nd round in the next post.

WBCCC Round 1 Update
This is the first update for the WBCCC, I guess some of you have been following some of the games there. There have been a lot of interesting games and some surprises a lot the way. As I'm reporting on the FICGS forum I will make most of this about the FICGS side. Here are some results so far and starting at the top boards.
B2 Uly(Vytron) vs Gino Figlio- Gino does a good job of defending a ..2.e6 line of the Sicilian. And both players agree to a draw after 34 moves.
B4 Daniel Parmet vs Sebastian Boehme- This was a Poison Pawn line of the Sicilian. The game ended before it even got out of book. A short draw, I think both people agreed that it was a good result for each player.
B6- Matt O'Brein vs Omprakash- A surprise if only for how short the game was. Matt shows his tactual muscles when his higher rated opponent much of had and oversight in this defense. As 23.g6! h6 24.Bxh6! and it looks like black has burned his bridges in this game.
B8-Stephanie vs Ruben Comes- This maybe the biggest surprise in round at least in terms of the bigger name on the FICGS side. Stephanie what looks to be a prefect opening all of the B90 lines and everyone agrees 32.Bc3! to be a new novelty and a very good one at that. Stephanie went on to grind Ruben down to a lost endgame. I very interesting game that has be to be seen to believe, I guess this going to show, that not all B90 lines lend to draws.
B13-Scott Nichols vs indrajit_sg- This was a long fought draw. When looking at the game early I thought white may have some chance to take advantage of his open g-file. But not a lot materialize later in the endgame(form the engines point of view).
B14-donkasand vs David Evans- David enter into dangerous territory with this B90 line. At move 19 he played ..Rb8 which looks to be a move to get out of book, because the other moves didn't look so good. Credit to David for finding a draw line in this game. Its another game with a look.
Kamesh Nookala vs Jimmy Huggins- What can I say I played an experimental opening and it backfired :) A well played game by Kamesh. Thanks for the chance to have a good fight with you.
Now on the 2nd set of games(Each player has 2 games in each round)
B3 Ramil Germanes vs Moz- Ramil here played a safe line in the B90 form the white side. So this looked like and easy draw.
B4 Sebastian Boehme vs Uly(Vytron)- Vytron plays and interesting side line of the Crao-Kann and play was very shape, but I got the feeling black played to ambitiously and had the worse of the position. He found a good defensive sacrifice and the good was hold to a draw. I think Sebi had winning chances, but I will have to look over the game to come up with an idea on that one. Anyway a great game to look over.
Ruben Comes vs Matthew O'Berin- Maybe the sharpest and most ambitious game in round 1. This goes in the the B97 lines, but Ruben goes for the Qf3 side line and produces a complex position after Rd3. I love this game so much I want to post the link again for everyone to please watch this game and post a comment about it.
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=20213
B13 Fulcrum2000 vs Scott Nichols- Scott tries his luck to be ambitious and backfires with his Bh4 idea. Even when looking at the game. I was thinking it to be a good idea, but as it turns out. It goes as just losing a tempo. I thought this was one of the more instructive games of the round. I liked the way white played the endgame.
And the last result I have for the round for the FICGS players is
B17-indrajit_sg vs Kamesh Nookala- This was an interesting draw were white plays and early sideline in the Sicilian that tends to be drawish unless black forces the play. Another well played game by both sides.
I just want to say there are a lot of games one should look at. As more results come in on the FICGS side I will posted. In my opinion one should follow Wayne's games I have enjoyed his play so far. He had to comeback some in his wild game with black vs deka, but I get the feeling this game will ended in a draw. I would also follow the underrated Matt O'Berin in games to come. He has proven to be a great player so far.

Houdini 1.5 leads TCEC comp. chess tourn
Advanced chess "centaur" players should be interested by the following:
A "super" tournament for computers, named TCEC, just started. Premier Division finals started with the participation of the world's top engines.
Tournament format: double round robin
The participants:
1 Houdini 1.5
2 Rybka 4.0
3 Shredder 12.0
4 Stockfish 2.0.1
5 Naum 4.2
6 Ivanhoe B47cB
7 Hiarcs 13.2
8 Critter 0.9
I don't know much on this tournament, actually it may be a CCRL/SSDF system-like but as a tournament (and without rating list?), anyway thus it was able to reach the chess news in Chessdom & Susan Polgar blogspot.
The point is that the supposed "possible" Rybka-clones Ivanhoe & Houdini (both based on Ippolit, just like Firebird) entered the race... and Houdini is leading already, ahead of Rybka.
It is announced that Rybka 4 is playing, does anyone know who's behind this version of Rybka and what is the hardware? Does Vasik Rajlich know about that?

Rybka 4 wins ICT10
Rybka 4 just won the latest edition of the International Computer Chess Tournament (ICT10, 10th edition) ahead of Deep Sjeng (surprise!?) and far from the other Chessbase engines: Hiarcs, Deep Shredder and Deep Junior...
Interesting to see that Rybka (by Vasik Rajlich) only lost to Deep Sjeng (by Gian-Carlo Pascutto) and won all the other games, including against the well known Hiarcs (by Mark Uniacke) and Shredder (by Stefan Meyer-Kahlen).
Rybka 8/9
Deep Sjeng 7/9
Hiarcs 6/9
Deep Shredder 6/9
Deep Junior 5.5/9
Komodo 5/9
The other participants were Pandix, The Baron, Spark, The King, Kallisto, Almond, RedQueen and Joker.

Rybka
I understand, I assume & hope that Vasik Rajlich has good reasons to think that RobboLito is a clone, that would be a reason enough to forbid to mention it in the forums dedicated to Rybka IMO... But it is true that if noone can prove it is not a clone & if there is no real reason to think that it actually is a clone, it would be not very "fairplay".
That's why I said I have no opinion on this.
The most surprising thing in all that is that RobboLito is open source. That makes me think that it is not a clone, but who can say it...
Thibault de Vassal (2009-06-22 16:41:00)
Discussion at Rybkachess
That's an interesting discussion... Once more, the confusion reigns between Freestyle chess (commonly played at classical & blitz time controls) and Correspondence Chess, particularly for centaur players who did not experience correspondence chess at a 2500+ level.
IMO (in brief) on several points :
1) All these made-for-engines books have no other interest than to "manipulate" chess engines & other made-for-engines books, actually this has almost nothing to do with correspondence chess (where they are completely useless at a high level, let's say 2300+) or even chess.
2) Many players do not realize the multitude of factors that appear to be more important that the basic strength of centaurs once the correspondence chess 2400 mark is reached and that still increases at 2500 and 2600... The higher the level, the more "opening books" depend on the recent games played by the opponent (and his level), the number of current games played, the score to reach in 8 games matches, the importance of rating, the goal in life, even the month/season for a few players and many other things according to the persons... Actually these "openings books" just live the time to use it one time, so a better term is preparation, actually opening books do not exist anymore in correspondence chess at a very high level, at most it may be useful against weaker players.
3) The previous point is enough to explain the rating changes of most 2400+ players ! In example...
- GM Farit Balabaev is a very experienced player who constantly has(had) more than 100 running correspondence chess games at several places for years, he's also a fast player, it is quite logical to me that he looks for quiet games and fast draws (or lose sometimes to very strong players who want to win more)
- Wolfgang Utesch, FICGS WCH finalist, like many players at one time in their life, decided that other things were more important and that correspondence chess was too time consuming, particularly once the 2500 mark has been reached...
- Eros Riccio obviously decided to win every correspondence chess competition at FICGS while playing a high number of games at several places AFTER having topped the FICGS rating list with the highest rating so far (which he did), so it is natural to look for a few quick draws in matches if 8 draws mean a victory for him (and a few rating points lost, that is quite inhuman anyway :))
- Michael Aigner tops most FICGS rating lists by playing only games at 40 days + 40 days / 10 moves time control, which is an enormous performance as obviously the longer the time control, the higher the rate of draws. I do not know how many current games he's playing at ICCF or IECG and other organisations but I suspect he plays a quite reasonable number of games.
- Xavier Pichelin may top the FICGS rating list this year as he's an incredibly dangerous player with White and Black and with a reasonable number of running games.
Many strong players also choose to play some tournaments for "fun" or to experiment openings and may lose some points while their real strength is over 2500 or more... so it is quite hard to make the difference between the real strength and correspondence chess ratings. So many parameters... It is likely that we'll see one day a 12 games match between Eros and Xavier (Michael do not play fast correspondence chess time control, yet I hope), we all wonder what rating could achieve Vasik Rajlich (Rybka's creator) and other very strong freestyle players but it is very hard to predict only by knowing their results in freestyle tournaments. Correspondence chess is a mirror of real life.

Rybka 4
Vasik Rajlich wrote a few comments on what can be expected from the Rybka engine/team in 2009 :
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=9199
Three engine releases are planned in 2009:
* Rybka 3+ - Rybka 3 playing strength, with bugfixes and cosmetic improvements, for Rybka 3 customers
* Pocket Rybka 3 - published by Convekta/ChessOK, packaged with their Pocket Champion interface, conforms to S. Tsukrov's Pocket-UCI protocol
* Rybka 4 - better search, better eval, new analysis features
"Our tournament goal for 2009 is to win a top freestyle event in 100% automated mode. (...)"
Very interesting, a new challenge for Eros :)

Rybka 3 encrypted
It seems that Rybka 3 would be actually even stronger that the commercial version of Rybka 3, Rybka team (V. Rajlich, L. Kaufman) explains that the compiled code was encrypted, as a consequence the engine would lose about 60 ELO points in that process.
A smart move by Vasik Rajlich to prevent his engine to be cracked by using simple decompiling tools. (ICE may help the most motivated though)

Chessbase Deep Rybka 3
Chessbase, who distributes the best chess engines (Fritz, Shredder, Junior, Hiarcs, Zappa...) now also distributes the little fish : Rybka 3 and Deep Rybka 3 are available.
http://www.chessbase.com/newsdetail.asp?newsid=4772
Rybka 3 (by Vasik Rajlich) is the reigning computer world champion and should be at least 80 points stronger than the previous version Rybka 2.3.2
Did anyone test it already ? What about the improvements (particularly Monte Carlo Analysis in endgames) ?
Rybka 3 book with 3,387,966 positions (260 MB) is also available.

chess engines
First of all, every chess engines is a choice, ie. about selectivity, and has consequences & weaknesses in particular positions. Fruit/Toga algorithm is really good but it has probably still much less chess knowledge than Rybka. I think Rybka's algorithm is really better also, Vasik Rajlich added some "human features" while other programs still think about chess like mathematics.
Rybka changed correspondence chess because Fritz or Junior (very strong chess machines) added to a good chess player makes a good centaur while Rybka is "almost" a centaur itself... Consequently a weak chess player can reach quite easily a 2100/2200 rating. That's the main reason...
Of course Rybka will always make some bad moves, but it/she builds an advantage move after move against other engines in most cases in 'calm' positions. HIARCS, that was told during a long time to think most like a human, was not a strong 'chess machine'. I don't know much about Hiarcs 11/12, but Rybka is a major improvement in this way IMO.

World Computer Chess Championship (WCCC)
All: JUNIOR has won over Fritz in Elista.RYBKA wins Olympiade Amsterdam. It got me thinking: instead of being an 'engine-to-engine contest can it be that the whole thing is a book-to-book contest? The program that has the best opening book with novelties will come out on top, invariant from the engine. Is that why RYBKA is so good? IM V.Rajlich? The future WC will be the program with the best book. The future WC tournament chess will be the one who knows this book. Maybe they will be one and the same person? Great news for the sport I think.

Rybka 2.3.2
Just after President's cup "Ultimate computer challenge" finished, Vasik Rajlich threw a new Rybka 2.3.2 in the chess engines arena... (partly explains the $100,000 challenge to Ilyumzhinov a few weeks ago)
Once more, Rybka 2.3.2 seems stronger than her predecessors with indcredible results (blitz time control) against Hiarcs 11.1, Zap chess Zanzibar, Shredder and so on... Maybe +35 elo points compared to Rybka 2.3.1 !

Rybka: $100,000 challenge to FIDE
The author of Rybka - undoubtly the strongest chess engine (Rybka 2.3.1), Vasik Rajlich challenges FIDE for a $100,000 match between Rybka and the winner of the "Ultimate Computer Chess Challenge 2007" between Deep Junior and Deep Fritz, that just started (first game drawn) :
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=1126
Also the match offer to grandmasters is more and more interesting :
http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=794;pg=1
I doubt Chessbase or FIDE would accept to organize & play such a match, even if Fritz 11 or 12 can beat the next Rybka... The war of engines is not on the chessboard nowadays but that's quite interesting to follow anyway :)

Cas particuliers
Je rajoute quand même qu'il y a effectivement déjà quelques cas un peu complexes pour lesquels je ne saurais pas si je dois ou non appliquer une pénalité... Il y aura de toutes façons toujours des perturbations de temps à autre. Une chose est sûre, dans ton tournoi il n'y a pas que des "serial droppers" ;)

Playchess Freestyle Tournament
Thanks for info, Samy...
What a crosstable, no less than 17 players finishing with 5,5 / 8
Petr, I understand your frustration, anyway that's why I play correspondence chess only over the internet. Losing a game thanks to a connection lost or strange rules is not interesting much :/
Several remarks while looking at the final crosstable :
The winner uses Rybka 2.3 mp, the others too :) .. Rybka's author (Rajlich) scores 5 out of 8 (pos. 18)
With Rybka getting stronger and stronger at fast time controls, Advanced Chess will probably become Computer Chess and finally Rybka Chess very soon. 1 hour + 15 sec is no more interesting.
I recognize some famous 'names' used on the defunct KasparovChess.com, King Crusher (5 / 8), Deep Thunder (3,5 / 8)... Correspondence Chess GM Mikhail Umansky scores 2,5 / 8... and last but not least, french forums superstar Olivier Evan scores 2,5 / 7 :)

Rybka 2.3.1
Rybka 2.3.1 beta is available, Rybka 2.3.2 is announced, quite hard to follow Vasik Rajlich's work day after day :) .. Rybka forum is very active and it seems Rybka 2.3.1 is the strongest Rybka and the strongest chess engine today !
I hope Fritz, Junior, Shredder and Hiarcs authors are working hard...

Rybka 2.3
More info about Rybka 2.3
www.rybkachess.com/index.php?auswahl=Rybka+2.3+readme
The new engine should be a bit stronger than the previous version, Vasik Rajlich ran a blitz match (1' + 1") between Rybka 2.3 and Rybka 2.2n2 and got a result of: +245 =607 -193 (52.5%, +17 Elo).

Rybka, Fritz and future...
Computerchess is definitely an exciting challenge... The community is fast-growing, new versions of chess engines appear every day, many dream to be the next Vasik Rajlich and to produce an engine that would beat the well-known Chessbase engines and the famous Rybka.
These days, I had a look at Fruit 2.1, TogaII and Crafty source code that are available to download, and started to implement new search & evaluation functions. It's quite easy to understand why chess programming is so addictive, so much done and so much to do... finally I did not enter this mad race without an ending, probably for the same reasons Anthony Cozzie (the author of Zap! Chess Zanzibar) and many others retired.
However here are my feelings about future of chess engines, and the fight that just started between most probably Chessbase engines (Fritz, Shredder, Junior and Hiarcs) and a new era of chess engines that started with Rybka...
First, it's quite obvious to me that Rybka (now Rybka 2.3) is only another one of a long series of chess engines always stronger than each others ! .. I expect the next ones to reach 50, 100 then 200 points more (and maybe more) on the next chess engines elo rating lists, a scale that definitely can't be compared to human elo rating list ! .. Several reasons to this : (1) Chess engines are human killers at standard time controls, but chess engines are far to play perfect chess yet. (2) The way ratings are calculated.
Rybka taught us several things IMO :
- Algorithms and evaluation functions are no more enough. Now chess engines have to play chess, not only search a tree of chess positions... That's probably what Rybka brought to computerchess. Since Fruit 2.1 & Toga II source code is available, and computerchess community is constantly discussing improvements in algorithms, evaluations of positions and new ideas, to implement a chess engine becomes easier so I have no doubt that new very strong chess engines like Rybka will come.
- To become famous, a chess engine must 'also' beat his rivals. I first thought that Rybka was designed to be an engines killer only (at least before to be an analysis tool) with some tricks exploiting most engines weaknesses. No, Rybka is also a great UCI engine, simply stronger and with many options & features. Like Vasik Rajlich, who is engineer and international chess master, you'll have not only to think like an engineer to create such an engine. However I still don't think it is the best analysis tool for correspondence chess, it doesn't play really better chess and in all cases it is not enough. More, Rybka 3, 4, 5 shouldn't influence correspondence chess (maybe even human vs. machine) much... Computerchess influences computerchess first.
It's written sometimes that the strongest chess engines could reach a IM, even GM level at correspondence chess. I definitely disagree with that, at least for the moment (it will take a long time yet), but as chess engines results tend to approach correspondence chess ones (means more and more draws), I do think chess engines have much to learn from correspondence chess players way of thinking, meaning : A more psychological approach, bonus for traps detection. Evaluate moves, not only positions. A more complex search, not 'only' iterative (brute force is definitely useless). No more anti-human style, speculative moves (=weakness, ie. Deep Junior) for speculative results against strongest chess engines, draws are prefered. To avoid positions not understood by the engine. Longer games, closed games (if supported)... Opening books should look like correspondence chess GMs ones (of course according to the engine's style of play) and no more been made of FIDE GM games. A better time management... Future of computerGo may teach to computerchess about some evaluations.
A chess engine must play good moves AND try to win (which is not always the same). It seems Fruit & Rybka play solid and are waiting to exploit their opponent's weaknesses thanks to a better "chess" algorithm/knowledge. As far as I have seen, Shredder & Fritz still have the best 'eye', they see far but fuzzy. Quite the same about Fruit & Toga developped by a great engineer, Fabien Letouzey : Less chess knowledge but an improved algorithm. As for Rybka, a great chess knowledge and probably a smarter algorithm (not better, smarter !) were probably enough already. The future best chess engines will be made by good chess players...
An interesting point is it could be not so easy, maybe even nonsense, to create the best analysis tool that would also obtain the best results against other chess engines. My first prediction is Rybka won't be the top rated chess engine ever, hundreds of new ideas will appear in all parts of chess programming, slowly breaking Rybka secrets, then speed will be a factor again. Deep Fritz, Junior, Fruit or Hydra are most probably the core of the next generations of chess engines... but there's a lot of work yet :)
My two cents.

Rybka 2.3
An interesting thread about Rybka 2.3 (should be available on february 12) and his new features, described by Vasik Rajlich. In a few words : stronger, new chess knowledge, better search algorithm, better positional play, bug fixes and an interesting feature called "randomizer" :
Quote : "You can put Rybka into a mode where she will play against herself over and over from the same position without repeating variations - she will systematically explore the space of possibilities in the variation, branching from the previous games at later and later points. It's an effective way to get a Monte-Carlo-based evaluation of a position."

Deep Fritz, Rybka & future
The Chess Challenge 2006 in Bonn between classical world champion Vladimir Kramnik and chess engine Deep Fritz 10 confirms (who ignored ?) the best chess programs can rivalize with the world champion in a match, but it first shows us these calculating monsters still have weaknesses.
Question is : What are the real improvements in Fritz 10 compared to Fritz 9 (engine speaking only) ?
Here is what I think about chess engines nowadays (Fritz 10, Shredder, 10, Junior 10, Hiarcs 10 and particularly Rybka 2.2) :
The way of think to play correspondence chess is (or should be) mostly human one combined with a chess engine algorithm. We follow the tree of moves like a program with our selective algorithm (much better than chess engines), applying our judgement of the position when necessary only. The point is we evaluate moves and we almost never evaluate a position twice.
Chess engines are very good analysis tools but are surprisingly not designed to be very good chess players. I think a major improvement in chess engines should be recognition of 'sufficient moves' : ie. it is no worth to always find the best move at a particular point of the tree, this reflection time could be used later... It depends on the evaluation of the position, on the clocks... Iterative model is quite basic (in a game at least !).
Another point is recognition of traps. This is the start of psychology in chess engines, and basics of the art of war. It first depends on who your opponent is, and on the clocks too. Finally, at the end of the tree, chess engines evaluate positions, but how many evaluate moves ? .. Speculative moves were a step, but it first shew chess engines were not able yet to see what move is worth to be analysed really deeper, consequently creating a 'human' weakness, particularly against some other chess engines.
I don't know how Rybka works, but as far as I read about this one that calculates much less positions (about 10 times) than Fritz, I wouldn't be surprised that Vasik Rajlich had implemented a better approach of human way of think, which is undoubtly the future of chess engines.
A good 'centaur' in ie. Playchess rapid tournaments is first a good choice between Chessbase engines according to the position and clocks. Fritz qualities probably apply best in standard games, where clocks are really designed for him. Among Chessbase engines, Hiarcs is probably the best Blitz player and could be the best correspondence chess player (even if it isn't the best CC tool for humans). Rybka is probably a kind of centaur itself (sorry, herself ;)), knowing when to use (in the tree !) brute force and more selective approachs - not to be compared to Hydra or Deep Blue which, on contrary, use most brute force.
My conclusion is chess engines have much to learn from humans yet, we'll see a Rybka 5 and Fritz 13, with much better results against other chess engines, but their results shouldn't increase a lot against the best humans in future. Finally, it will never be a good correspondence chess player :)
My two cents.
If I find time, I'll continue to implement my own chess engine..... but it's a lot of work :/
