I think it is unimportant which machine wins this match. What is important is new things have been discovered and I hope to get the feedbacks from the people who spent countless hours making these machines better.
In game 5, it is coming to an end as Zappa announced mate in 40 or something like that. The score will be 3.5 – 1.5 in favor of Zappa.
More to come later.
Chess Daily News from Susan Polgar
Zappa has won 3 games in a row.
It is simple, but just to mention it: To win this match, Rybka would require 4.0/5 from the remaining games, and Zappa only 2.0/5.
3 draws in the upcoming 5 games would be enough for Zappa now, to draw the match. Rybka will have White 3 times, in the 2nd half of the match.
Wasn’t Rybka the best chess engine?
The operative word would appear to be “was”.
I should say, on such a big machine (8 CPUs?), Zappa is clearly better than Rybka. Or is it that Zappa the Mexico version has really improved? Since both are under chessbase, then perhaps we will see Zappa vs Junior after this 😉
Rybka has problem in ending techniques. That’s the weakest part and it has to be repaired.
Zappa is the best engine for sure now, but the war has not ended yet.
This makes engines’s war very interesting. This is part of history……
that one day Kasparov was beaten by Kramnik, ops sorry Rybka was beaten by Zappa….
How about an idea that maybe something wrong with Rybka’s Computer? Hijacked?
Or Zappa might get help from Junior of Fritz?
or Zappa has bluetooth or wifi or something that get helped from outside help?
Are they detect zappa or Rybka with flesh detector? 😉
Was Zappa cheating ?
Peace man. Haha.
Let the best engine win.
Turns out Rybka is a bad engine.
Excuse my wording, but some of the comments here are utterly stupid. Rybka suddenly a “bad engine” just because it has lost three games?? Come on… and wait for the final match result.
Soon, we will have reliable results from engine vs. engine, Zappa Mexico vs. Rybka 2.3.2.a and others, from the rating lists where no supertuned match openings are used. Hundreds of games are required.
Also, note that in that match, the 64 bit versions are used on 8 cpu cores, while I guess 90% of us still have dual core or even single core computers only, and 32 bit OS. The strength relations are not identical, because Zappa’s main advantage is that it gets the best speed up from multiprocessing.
Zappa Mexico can already be purchased, from http://www.shredderchess.com
520 blitz games on 4 cpu cores are much more reliable than 10 games on 8 cores, each. CCRL has already 520 blitz test games with Zappa Mexico on 4 CPU (4 cores):

The current public version of Rybka, 2.3.2a on 2 CPU is 71 Elo ahead of Zappa Mexico on 4 CPU. Of course, the picture may look a bit different on longer time controls. But in my opinion, this is a clear indication that Zappa Mexico will not overtake Rybka, in any rating list.
I said bad engine, because I felt there is an overblown publication that Rybka is the no 1 engine in the world, with over 3000 elo blah blah blah .. etc etc.
So how come it failed to beat zappa that I have never heard before ?
Did something go wrong here ?
If you got the best engine in the world, so what ?
The computer algorithm comes from human .. and there is always human who will improve the computer.
Not the other way around.
That you didn’t hear of Zappa before, makes Rybka a bad engine? What logic is that?
Zappa was computer chess world champion 2005 and second in the world championship 2007, and it is second strongest engine on multiprocessor for quite some time now. 3rd is Naum 2.2.
Also, a small number of 10 games is virtually irrelevant as a test. Rykba remains strongest engine, no matter what the result of this match will be.
Nevertheless, a 2 points lead by Zappa is unexpected and respectable.
