I agree with you Uri 100%,even more when we don't know what are the latest improvements of Hydra regarding the playing strength....Uri Blass wrote:I am not interested in rybka vs hydra match.Leto wrote:I'm more interested in a Rybka vs Hydra match, I already know that the best human chess players are inferior to chess engines.
I see no reason to care about playing strength of hydra that is something that nobody can get.
It is more interesting to know the
playing strength of commercial engines or free engines

If you're not 2500+, you shouldn't make such statements. No wonder GM's detest this forum

Your statement is illogical. One does not have to be a car to know that cars can outrun humans. Logically one does not have to be 2500+ to know that the best human chess players are inferior to top chess engines.Terry McCracken wrote:What's your chess level?

The conditions are of the Rybka teams making, so they should have no right to grizzle afterwards if things go badly.nuff wrote:Larry stated that a strong human GM has expressed interest so it would be interesting if the match takes off. Isn't a 3 move opening book too much of a concession? If Rybka suffers a reverse you can bet that will be one of the sticking points.

Programs are calculators, humans create, machines don't, and the best human chess positionally and tactically are still beyond computers.
Computers have only one thing that humans don't, stamina.
They can't create, they can't multi-stage plan, and positionally are not in the same class.
You haven't the ability to see this. In fact I doubt you know the game very well.
Do you play chess?
What computer can reproduce the brilliant play of Anand?
None!!!

Re: Rybka vs top human match?? Hydra vs Rybka would be bette
This is simply not correct.
Humans have something that they call experience.
They may know that some type of move never works based on their experience so they wll not find it because they will not analyze it when computers who analyze every possibility may find it.
There is book that is called creative chess and people found that computer found most of the moves in this book so you can say that they are creative.
I believe that top humans are relatively not creative in 120/40 games because being creative mean finding moves that seem to be illogical based on your experience(if you suspect that they are good based on your experience you are not creative and you simply use the experience that you know).
Humans have no time for analyzing lines that they consider as illogical in 120/40 games and they can spend their time better by looking only at candidate moves that they consider as logical.
I also suspect that you will find programs that find Nc7 at tournament time control.
Here is some analysis by a free program:

Utter nonsense! I've played thousands of both human and computer chess games. I've analized both, and humans win hands down for creativity and ingenious play!!
Programs are calculators, humans create, machines don't, and the best human chess positionally and tactically are still beyond computers.
Computers have only one thing that humans don't, stamina.
They can't create, they can't multi-stage plan, and positionally are not in the same class.
You haven't the ability to see this. In fact I doubt you know the game very well.
Do you play chess?
What computer can reproduce the brilliant play of Anand?
None!!!

Whose superior? Not the computers!!! Anand shows his mastery and depth of play, the superiorty of humans over machines!
A computer can't reproduce this play in 40/2 TC's
Computers are not in the same class!
This is Chess!!!

24...Nc7!!
Although I fully agree with your preference for human creativity, your example is not adequate although the game is a real gem.
Here is Chessbase comment after the game :
(http://www.chessbase.com/newsdetail.asp?newsid=2864):
"23.Qc3N. Karjakin deviates from Leko-Vallejo in Monte Carlo 2005, where 23.Qe2 was played and the game ended in a draw after 67 moves. But Anand is prepared: 23...Qa8 24.Bg2.
24...Nc7! An amazing move by Anand, played á tempo and obviously coming from home preparation."
Anand himself said that 24..Nc7 was home preparation...
... and he just declared that his home prep is largely computer-based.
So this wonderful game is probably not the best example for showing human superiority over the comp ...

Re: Rybka vs top human match?? Hydra vs Rybka would be bette
Uri, there are positions that only the human mind can solve, the most creative chess is still produced by humans.Uri Blass wrote:This is simply not correct.
Humans have something that they call experience.
They may know that some type of move never works based on their experience so they wll not find it because they will not analyze it when computers who analyze every possibility may find it.
There is book that is called creative chess and people found that computer found most of the moves in this book so you can say that they are creative.
I believe that top humans are relatively not creative in 120/40 games because being creative mean finding moves that seem to be illogical based on your experience(if you suspect that they are good based on your experience you are not creative and you simply use the experience that you know).
Humans have no time for analyzing lines that they consider as illogical in 120/40 games and they can spend their time better by looking only at candidate moves that they consider as logical.
I also suspect that you will find programs that find Nc7 at tournament time control.
Here is some analysis by a free program:
My hardware is not the best(only A3000 2ghz) and Galurung2-epsilon/2 does not use parallel search.

There are tougher examples than this one and computers can't solve them.
That is a fact. You know this has to be true or corr. is dead!
There have been positions posted here that computers can't solve.
That's a fact. The best humans still can find the hardest tactics in very long sequences.
Computers can't create, they can only calculate, and some have better selective searches to find most but not all GM combinations.
That is a fact.
There are endgame positions that computers can't solve but humans can, that is a fact.
The best humans are still superior to the best programs in some amazingly complex positions.
That is a fact!
The machine can do only one thing better, not tire, hence they win more matches against humans.
But Junior and Fritz were lucky to draw Kasparov, and that too is a fact!
We both know Kasparov outplayed them both, but finally made human errors and didn't bring the victory home.
Computers simulate chess play well but still fall short of the mark to show they are in every way better, that is a fact!
