Re: New idea for a fair Human-Machine battle without handyca

We can resolve our dispute if a top GM will be allowed to take back on a >0.3 blunder and 3 times at any time against Rybka on any hardware. I can bet that the top GM will win in a 6 games match. Kai Losing becomes impossible. Do you know a reason why any elo 2000 player could lose against Rybka3 u...

Re: New idea for a fair Human-Machine battle without handyca

Larry kaufman never said that the latest rybka positionally is at 2400 level. Maybe he said that Rybka's evaluation is at that level but it is clearly a different claim. I am almost sure he said that, and anyway, it is more meaningful to say that than that eval is 2400, how do you quantize the Elo ...

Re: New idea for a fair Human-Machine battle without handyca

I can add that many drawn human-human games at the high level do not include tactical blunders and the reason that the same humans are more likely to blunder against chess engines is simply that the chess engines can get a positional advantage and it is easier to blunder when the opponent get a pos...

Re: New idea for a fair Human-Machine battle without handyca

tactical blunders is not the reason that humans lose against computers. You can even allow humans to take back every move when the evaluation of the computer improves by more than 0.3 pawns and I expect the computer to win the match because the computer play better positional moves. Uri Would you p...

not very interesting!
Just to avoid crass tactical blunders by humans. Might not be a strong engine helping the human, just an average tactical one. Otherwise you have to handicap the computer, which is again not very interesting.

Re: New idea for a fair Human-Machine battle without handyca

I think you fail to realize how much engines have improved since Kasparov beat Junior ... they have improved tremendously, by maybe 300+ ELO points on equivalent hardware alone. Add to that hardware advances and we are talking about maybe a 400 to 500 ELO swing, now that is a lot. Engines yes, by 3...

Re: New idea for a fair Human-Machine battle without handyca

I disagree that GM's are better than comps in the openings. .... Uri From what I saw in Kramnik and Kasparov matches, at least super GM's play evenly or even outplay comps in the opening. Opening books do not benefit from such advantages as hardware based engines, so I expect the current opening bo...

Re: New idea for a fair Human-Machine battle without handyca

The best way for humans to be able to compete with computers is to have different time handicaps. This ofcourse is increasing in the computer's favor linearly as hardware increases. I can still win tons of games on a slow P4 against R3 if it has 1 minute and I have 15 minutes. On an Octa things cha...

Re: New idea for a fair Human-Machine battle without handyca

What databases? GM's don't have problems with comps in openings, they are actually better there. And there are no middlegame databases, and hard to build in foreseeable future. That's the stage of the game where GM's are much weaker. So, a database is of small importance (I think Kramnik played Frit...
