May-29-06  dehanne: No Fruit?
May-29-06  hitman84: <No Fruit?>Only commercial engines are taking part.

round 6

Deep Junior - Rybka 1/2

May-29-06  borisbadenoff: <<No Fruit?>Only commercial engines are taking part.> Fruit is also a commercial engine by now.

And I don't think this statement is true. For example Crafty(?) is no commercial engine

May-29-06  hitman84: <borisbadenoff><Fruit is also a commercial engine by now.>Yes but is not competing for commercial success.

Zappa,Rybka are half clones of fruit.

Crafty is an opensource.Its gradually being upgraded that is why you can find so many versions of crafty.I feel some sort of research is bieng made.

May-29-06  hitman84: <Crafty is a direct descendent of Cray Blitz, the World Computer Champion from 1983 to 1989. >From Crafty's bio. has a long history.

May-29-06  cotdt: OMFG BYW is even worse than ETABETA!
May-30-06  borisbadenoff: <cotdt: OMFG BYW is even worse than ETABETA!> I would say that BYE is the disqualified LION program. Which means that probably they decided that every program which still should have played against it gets an automatic win. Or something like that. Even if doesn't seem very fair to me regarding the other programs.
May-30-06  borisbadenoff: <> BTW could somebody please correct the program names. Because now there are 21 programs listed with only 18 taking part.

Above are 2 different writing forms used for:

Chaturanga 2126 / Chaturanga
Uragano_3D / Uragano3D
Deep Juniou / Junior

May-30-06  borisbadenoff: And for those interested.

Ikarus is the new Computer Speed Chess World Champion

May-30-06  spirit: what's FRITZ's ELO
May-30-06  chessmoron: What's the best free chess software out there?
May-30-06  cotdt: the best free chess software in my opinion is the free version of Shredder, I think it is called Shredder Classic. If you mean the strongest free engine for analysis, then it'll be Fruit or Rybka. however, these engines don't provide alternative variations like the commercial engines do.
May-31-06  mandar: Is Rybka or Fruit free to download?If yes then from where can i download?
Premium Chessgames Member
  WannaBe: <mandar> Fruit is free, earlier version of Rybka is free, (commercial version costs money) you can find them via search engines.
May-31-06  jhoro: <What's the best free chess software out there?> you need GUI interface and one or more engines. The best free interfaces are <Winboard> and <Arena>. The latter has a lot more options, including separate variation board, support for UCI and Winboard engines, is well threaded, provides copy/paste of FEN positions and PGN games and has a nice engine management. It is available for free from here they have a new beta, but I'm still using V1.1. It comes with free engines including Spike 1.0a

Now to the best free engines, my favorites are <Toga II> and <Spike 1.1>. Toga is continuation of Fruit 2.1 which was free, but went commercial since Fruit 2.2. <Toga II 1.2 Beta 2a> is the strongest Toga in my experience. It is stronger than Spike which is doing very well at the WCCC. From the Rybka's only <Rybka 1.0 beta> was free. It is very strong, but a bit unstable in my opinion. The initial <Zappa 1.1> version is also free, but not as strong. <Crafty> is the original open source engine and is a good match for Winboard (doing well at WCCC too). Go to and follow the links for each of the engines. Unzip and in Arena press "New Engine" and select the exe to install. Arena has help in multiple languages... Then if one day you want to beat other people's engines you'll have to get opening books and tablebases...

(btw i think Shredder Classic is a trial version - 30 days)

May-31-06  Marvol: From the front page of

"The world's strongest CPUs duke it out."

"Strongest CPUs"!?!? Is that some kind of metaphor, poetic liberty or plain stupid? I can't decide between these options...

9 Uragano3d, [3] =:= BYE

May-31-06  jhoro: Shredder went for draw by move repetition at move 20 against ParSOS. Those engines should get some conditioning from Topalov. They are so young, but so afraid not to lose.
May-31-06  Dionyseus: Standings after round 10:
1. Junior 8/10
2-3 Shredder 7.5/10
Rybka 7.5/10
4. Zappa 7.0/10

One more round remaining, it will be played tomorrow, tiebreaks afterwards if necessary.

May-31-06  chessmoron: Any one has Zap! Chess (the commercial Zappa engine from chessbase)? Is it any good?
May-31-06  CapablancaFan: Shredder is a very hard program to defeat. It's record even against otherrograms is impressive.
Jun-01-06  borisbadenoff: As Junior has won his game against IsiChess.
Junior is the new WCC-Champion with 9/11.
Shredder being just half a point behind with 8.5/11. Rybka will probably also make the full point. Sharing the second place with Shredder
