No, the games are broadcasted at Playchess.com, but the games themselves are played in Pamplona. |

| May-13-09 | | timhortons: <Dionyseus> i think i posted a live relay last 2 day at kibitzer caffe. I lost the link for the live relay of world computer championship. Do you have any idea if this 52 core computer has a complete end game database?I am not very well informed on this thing. |

No, if it had a complete end game database the game of chess would be solved. The six piece endgame database has been available for some years, unfortunately the seven piece endgame database has not yet been completed and has been progressing very slowly. |
|
| May-15-09 | | Dionyseus: Today is a rest day at the WCCC, tomorrow rounds 6 and 7 will be played. Rybka is currently in the lead with a perfect 5/5 score. Second place is Junior with 4.5/5. Rybka will be black against Jonny in round 6, and in round 7 will have the white pieces against Shredder. |
|
| May-17-09 | | Dionyseus: The development version of Rybka 4 has won the 17th World Computer Chess Championship, scoring a win today in the final round against Junior to finish with an 8/9 score, a full point and a half ahead of the three engines that finished tied for second place, Deep Sjeng, Junior, and Shredder. http://www.grappa.univ-lille3.fr/ic...

It is the Rybka 4 (development version) cluster that was used to win the WCCC Open (no hardware limits) category. It contains 52 cores. You can read more about it here:

 | | HeMateMe: Gorgeous game, Rybka vs. Shredder. A long combination, trapping a queen in the middle of the board. I hope they continue to occassionally throw one of these things into a gm tournament, or have a match, just to see how strong the programs are, relative to top level GMs. No fun for a player, getting punched out by one of these, but it's the only way we can guage relative strength, by seeing how bad they beat the best human players. That display of Rybka's 52 core processor kind of reminds me of the cover of the Pink Floyd album 'Umaguma', when the Floyd's equipment is all stacked up in a pyramid shape. |

| May-19-09 | | whatthefat: <HeMateMe: Gorgeous game, Rybka vs. Shredder. A long combination, trapping a queen in the middle of the board.> Really? For me, that game was a crystal clear illustration of just how stupid engines can still be. Remember that this game was in the Open section of the tournament. I don't know what Shredder was running on, but Rybka was on 52 cores and Deep Sjeng on 56 cores, so that gives some indication of the type of hardware being used. Looking at the game, after 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Nxe4 5.Qe2 Ng5 6.Nxg5 Qxg5 7.d4 Qe7 8.dxe5 Nd4 9.Qd3 
click for larger viewShredder plays the obviously risky 9...Qxe5?! when 9...Nxb5 looks like a much safer option. After 10.Nc3 Bc5 11.Qd1 Ne6 12.Re1 Qd4 13.Qf3 0-0 14.Re4 Qd6 15.Rh4 Qe5?! it's clear that Black's opening play has been rather farcical and White has excellent compensation for the pawn. What human would have devised such a strategy as Black, moving the queen to and fro? I'm not sure at which point exactly Shredder's book ended, but I imagine it wasn't any later than Rybka's at 10...Bc5. |

| | HeMateMe: But most PEOPLE would have thought they could eat the pawn and still get normal development. Sort of like the poison pawn in the Sicilian, but not so obvioulsy risky. Most human players would not have found the detailed tactical plan to build up a winning positon while attacking the Queen. Ask one of the grandmasters who have lost to Shredder or Rybka. There are a few. Thanks for the Floyd visual! Those folding, double albums had many purposes, back in the day............ |

| May-24-09 | | Dionyseus: As some of you may have heard the author of Naum 4, Alex Naumov, has decided to end major development of Naum, claiming Rybka's author is too good as his reason. This is very bad news because Naum 4 is the only engine that really seemed poised to challenge Rybka's supremacy. Naum 4 is according to the major rating lists CEGT and CCRL the only non-Rybka engine that is stronger than Rybka 2.3.2a. So consider that for a second, if Alex Naumov had the ability to time travel and went back one year, his engine would have been number 1, at least briefly. http://rybkaforum.net/cgi-bin/rybka... |

Fritz will give Rybka good fight in the market. |

I'd be surprised if Fritz isn't beating Rybka 3 in sales. Rybka 3 only recently joined the Chessbase team so they are only catching up at the moment. Chessmaster has them both beat in sales however, and it has been that way for a long time. With editions of Chessmaster available even for video game consoles it is hard to compete with that. |

I do have chessmaster 10th edition and honestly , some of its aspect i was never happy of it, it cant help me analyze the position by giving a plus score and minus score, while my rybka 3 analyze the game as i observed it at play chess.com. One thing is that chessmaater chess software could be bought in computer store like future shop in montreal while fritz and rybka could only be bought in special chess store. |
|
| Jun-14-09 | | SugarDom: Chessmaster has excellent tutorials and a chess academy. Its tops for creating tournaments and modifying computer personalities. While Fritz and Rybka are for serious players. |
|
| Jun-14-09 | | SugarDom: Timhortons, i dont know what you are talking about Chessmaster does not give plus or minus score, coz it does just like Fritz. Only thing is Chessmaster is not as strong. |
|
| Jun-14-09 | | timhortons: <sugardom>
<i dont know what you are talking about Chessmaster does not give plus or minus score> ok sugardom, can you give me the evaluation of chessmaster on the endgame position of this game? Post the evaluation here of chessmaster.

| Jun-15-09 | | SugarDom: I'll download chessmaster challenge, the free edition first... i dont have it in this computer |
