  REFINE SEARCH:   White wins (1-0) | Black wins (0-1) | Draws (1/2-1/2)  

Kibitzer's Corner
May-07-06  Dionyseus: Keep in mind Rybka still doesn't support multi-processors, which makes Rybka's wins even more impressive.
May-08-06  cheski: What an impressive win by Rybka.
What was the <time format> of these games? Like a human tournament, 40/40/20?
May-08-06  Dr. Funkenstein: Hmm I don't forsee strong sales for the Usurpator computer system in the future.
May-08-06  panigma: Does anyone know:

Who decides to resign in these games? Does the computer resign when its own eval hits some certain value (in the other computer's favor?)

May-08-06  notyetagm: <panigma> Usually the operator resigns when he see that the game is lost and his engine agrees with his assessment.

If the engine's operator evaluates the board position as lost and the engine sees -4.00 , there is not much point in playing on. Computers do not make the tactical mistakes that allow miracle saves in the endgame.

May-08-06  notyetagm: A tremendous tournament for Rybka, again. Only deep Deep Shredder was able to take 1/2 a point from Rybka.

When it becomes available later this year Deep Rybka will be like a chess-playing god.

May-09-06  doremi: Fritz did not play, but considering that it is about as strong as Scredder, we could expect Fritz to score around 6.5/9 as well, 2 points behind Rybka.

Kramnik will be playing the second best computer, i.e. Fritz, later this year, and the promotional slogan 'last chance for humankind to beat the computer' loses credibility if he does not play against the best computer.

I don't believe that Chessbase is going to go with the Rybka engine though, rather they want promotion for Fritz!

May-09-06  chessmoron: Where's Zappa or Fruit?
May-09-06  chessmoron: <doremi> Have you heard of Zappa?--much better than Fritz
May-10-06  doremi: Yes, but Zappa is considered second tier by most, though. Fruit was the wave before Rybka, but was itself drowned by the Rybka wave.
May-10-06  MrSpock: Please don't forget Hiarcs 10, the number two of the swedish list.
Premium Chessgames Member
  norami: How come on that swedish list it's always 256MB 1200MHz? Can't they do better than that?
May-11-06  Sith: Zappa is the best? But zappa is single core isnĀ“t? Can zappa beat shredder dual core? Well Shredder was using atlhon 64 x2 dual core and is not ease to say: Zappa can beat him!
May-12-06  notyetagm: <doremi: Yes, but Zappa is considered second tier by most, though. Fruit was the wave before Rybka, but was itself drowned by the Rybka wave.>

Yes, <Rybka> is the strongest chess engine currently available by an unbelievable margin.

May-12-06  chessmoron: We will wait see who is the best: Rybka or Zappa in the Chess Olympiad in Turin.
May-12-06  notyetagm: <chessmoron: We will wait see who is the best: Rybka or Zappa in the Chess Olympiad in Turin.>

Rybka has already defeated Zappa; see Zappa vs Rybka, 2005.

May-12-06  chessmoron: <notyetagm> I know. But it is still one game. Besides, there aren't enough tests between the new Zappa version.
May-12-06  notyetagm: <chessmoron> Can you tell me more about this "new Zappa version"?

Hopefully the Rybka versus Zappa rivalry will be as good as Anand versus Topalov.

It would be good for computer chess if Zappa beats Rybka at the Olympiad but we will see.

May-14-06  Dionyseus: <Notyetagm> Basically he's talking about the multiprocessor version of Zappa. A quad (4 cpu) Zap!Chess Paderborn 64-bit beat Rybka 1.2 64-bit (still single cpu) 25.5-24.5. You can read more about this extremely close match here:

It is currently 1 elo point higher than Rybka 1.1 in the all-versions list, but note that it has not been assigned a ranking yet because it only has played 79 games so far and it requires at least 150 games. You can see the list here:

May-14-06  notyetagm: <Dionyseus> So Zappa on 4 cpus is approximately equal to Rybka on 1 cpu. Damn! That is some advertisement for Rybka.

No engine will have a chance when Rybka is finally available in a multi-threaded version.

May-16-06  jaime gallegos: why Rybka played only 3 games with Whites ?
May-18-06  cotdt: engine vs. engine strength is different from engine vs. human. some of these top engines are pretty average against GM's positional play.
May-23-06  ryanpd: <cotdt> Can you give me an example of a top engine that performs "average" against the typical GM?
Aug-08-06  sharpnova: <doremi>
fritz is not the second strongest engine, nor was it at the time of your post. for a long time before, fruit was significantly stronger than fritz. hiarcs 10 is as well.
Aug-22-06  DANIEL SO: rybka is a great chess computer going undefeated
