But it´s obviously dangerous enough. Vas, look out! :)

DF11, will be close to 232a
Ok at that time R3 shoult be out but we currently know nothing about R3

Fritz11 is weaker than Rybka even when the 32 bit version of rybka is used.

That's nice, those guys who bought Rybka 1 about 1 3/4 year ago still have a better engine than the latest Fritz :)
A very, very strong engine, plus the GUI and the playchess membership will make Fritz 11 a very attractive buy.
The changes in the GUI are limited, so it's indeed attractive for those who don't have Fritz 7 ,8 , 9 or 10 but if you have one of those versions and Rybka, I'm not sure why you should buy it.
I like to use multiple engines to analyze positions and such. Rybka is definitely one of them. I also like DS11 and H11 and F10. They may not be stronger than Rybka, but they are still very, very strong.
After all, Magnus Carlsen may be 71 Elo behind Vladimir Kramnik, but he is still a very, very strong GM, right? ;-)
> After all, Magnus Carlsen may be 71 Elo behind Vladimir Kramnik, but he is still a very, very strong GM, right? ;-)
Most people don't have enough money to buy them both. This could lead to piracy. :-(
If you can't afford it, don't buy it. Or, if you know something is coming in the future, save up for it if possible. DF11 is not being released until March. That's 3+ months. Try socking away $20-40 USD to help pay for the program in March.
>The idea that "Since I can't afford both, I'll pay for one and steal the other" is sad.
I'm tempted to start a poll to find out whether people think stealing both of them is morally better than doing that. :)

It is mentioned on the Tal Memorial website too, but no details are given.
Rybka versus Rybka? :-D

And what do you think about the so-called “advanced chess” match with Anand, where you can use the computer’s help?
This is purely a show. In this form of play, the computer’s role is 80% and yours only 20%. But this 20% is decisive. You have to know how to use the computer well, when to turn it on and when to switch it off. I hope I manage to do so.
After reading this, my money will be on Anand! :-)

> You have to know how to use the computer well, when to turn it on and when to switch it off.
LOL, I sure hope he knows he should only switch it off if it crashes due to too much overclocking. :)
1) Ripping open their computers,
2) Installing better cooling,
3) Going into the BIOS to overclock, and
4) Installing a 64-bit OS to get a 60% speedup with Rybka
before starting up their engines.
Actually, I'm wondering which engine they will end up playing with. I'm assuming that this will be chosen by which engine distributer is willing to pony up the most sponsorship money rather than by the contestants, but I haven't heard anyone publicizing the advanced chess match, so maybe this isn't the case. I guess we'll see in a few days.

>Indeed, if compared with Fritz 10, the engine seems to have improved quite a bit, but if compared to Rybka I wouldn't call it "very very strong" since >it's still clearly behind Rybka.
It is not clearly behind Rybka but we just have an indication that is behind in the current setting of course.....
Also except from engine-engine games there is the analysis field where Fritz 11 may be better than Rybka there. Or may not of course.....
MAybe there are some positions where Fritz's evaluation is better than Rybka's, but since Rybka is the stronger engine (and the best positional engine at the moment for sure), the quality of her analysis is simply higher than Fritz's.
I know, Chessbase is trying to tell you that playing strength and quality of analysis is sth. different, but playing strength is proportional to quality of analysis, so no wonder that the top players (Anand, Morozevich, Shirov, Grischuk, Short, ...) use Rybka! (And who else could judge better on the quality of analysis?)
If you have a list of a positional test suite AND a tactical test suite AND an endgame test suite, for different time periods(10 minutes per move, 1 hour per move, etc) that shows after all these 3 tests that Rybka is better than Fritz 11, then you can convince me, but until then i just know that Rybka 1CPU seems to be better from Fritz 11 1CPU in eng-eng matches only and not for analyzing purposes too.
As for the GM's you mentioned the use of Rybka does not mean Rybka is the best since perhaps all these GM's haven't compared all other existing engines for analyzing purposes.....
And also where did you see that these GM's use Rybka only and not Fritz for their analysis? And only is important since if they use Fritz too then your argument is not valid....
Test suites only tell you sth. about the quality of the engine in extreme situation which are not as frequent as the type of positions which occure in engine-engine games. So I doubt if they can really tell you more, anyway, Rybka is pretty good in those tests, only in solving tactics some engines are faster, but Rybka winfinder is the strongest engine there, so you have got the strongest engine and the strongest tactical engine with Rybka :) . For endgames I know only this test: http://glareanverlag.wordpress.com/2007/09/07/hundert-schach-endspiele/#more-116 , Rybka wins there too.
Two examples where WinFinder 2.2 is relatively slow:
1...Bxe6 is the toughest defense.
Avoid 1.Nxe4 which is a blunder.
As for the topic Fritz 11 vs. Rybka, I think George WANTS to believe that Fritz 11 is better, and will defend this desire against any facts, as long as possible. Maybe it's like in love, where facts are almost nothing and emotions rule. :-D

You are wrong to think that.....
And can you quote any statement of mine that i say that i believe Fritz 11 is better?
You can only collect some facts to show that Rybka ist most likely the best program for analysis at the moment.

I'm not sure I agree with this because I think that playing style is also important. For instance, suppose you could have your games annotated by Tal, or a GM that is 100 Elo below Tal but plays in a more conventional manner? I'm not sure that Tal's analysis would be more helpful (at least to me :-)).
The second aspect is that engine analysis can (and in my opinion should) be done going backward through the game. Rybka is certainly the strongest engine going forward through a game, but because of the way things are maintained (or not maintained) in hash, I'm not sure that Rybka is strongest going backwards (i.e. it definitely has a harder time keeping multiple lines in hash than, for instance, Zappa does). Permanent hash sometimes helps, but doesn't really resolve this issue (I'm hoping Vas improves this aspect in version 3).
Feel free to rebut these comments. I certainly wouldn't analyze without Rybka, but its relative strength in analysis is not nearly as clear to me as its relative strength in engine-engine play.
Regards,
Alan
I don't agree on this. I'm also a more positional player but Tal's analysis would aim more fore attack, that's true, but would also show a good understanding of the position. This would mean that I could choose other lines but Tal would have explained the main strategical ideas and maybe also some quiet lines he personally wouldn't play. Reducing Tal on a "attacking only" player seems a bit too simple to me. (The same for Morphy, he was also not that bad at positional chess!)
Anyway, since all the top players use Rybka (and they have different styles for sure, also active, attacking players like Topalov and Shirov use her... which type of analysis should Fritz offer that Rybka doesn't give?) so why do you still think like this? It's somehow a very strange way of thinking.
Putting this a different way, if I had exactly the same clubs as Tiger Woods, I'd still be a crappy golfer.
Alan
Alan
yes but Deep Fritz 11 would have been much more attractive. Now Deep Fritz 11 will be competing against Rybka 3...bad strategy by chessbase.
IMHO, it's a big jump, with respect to the other engines, isn't it?
>Fritz11 is weaker than Rybka even when the 32 bit version of rybka is used.
And how do you know for sure? These are just indications that it is not stronger. But error bars and level of confidence show that we are not sure to speak with 100% confidence that Fritz 11 is not stronger.....
Also even if it is not stronger from Rybka in Fritz-Rybka games, even with 99% level of confidence and huge amount of games where range of errors does not concur, perhaps it will be stronger if we play against many other engines and get an ELO for Fritz....
http://www.husvankempen.de/nunn/40_4_Ratinglist/40_4_AllVersion/27.html
You can decide to believe that the truth is somewhere outside of the 95% confidence, as the error margins don't overlap, but how realistic is it? I can accept such figures easily. What is the problem? I also don't think that longer time controls will close that gap.
Btw. I noticed something strange on that list... Rybka 2.3.2a/2 CPU is rated lower than on 1 CPU, 2950 and 2973?! Error margins are small for both (600 games have been played with the 2 cpu version). Seems strange to me.
