Re: WCCC - Rybka v Hiarcs Round 8
I am thinking that Hiarcs may be the winner of this one. I am wondering what it can do on equal hardware. I would like to see a match between these two on equal hardware.

According to Lukas, the miracle man of the 40 clusters,
the win over Hiarcs is mainly due to Jeroen, the
book author.

Re: WCCC - Rybka v Hiarcs Round 8
Jeroen's book (Chessbase Rybka Book) for Rykba gives 8. Nd5 and 8. Bd3, so what is the story on this.
Thanks
Thanks

there are two moves, 8. Nd5 and 8 Bd3. Why Jeroen did not use
8. Nd5, considered the best? The war of openings, at this level,
it´s complex, maybe Jeroen knew that 8. Nc4 would be played by Rybka,
and the opening was very good for Rybka.
I already saw this strategy being used on Playchess

Re: WCCC - Rybka v Hiarcs Round 8
I guess 7...Rb8?! is a playchess machine room invention. There is not a single human game in the databases. After 8.Nc4?! Black has a chance to get back into known theory by transposition with 8...Be6.PauloSoare wrote:I don´t know, because in the Rybka 3 book , by Jeroen,Dr.Ex wrote:Isn't that Nonsense?PauloSoare wrote:According to Lukas, the miracle man of the 40 clusters,

The move 8...Nf6? was refuted convincingly in the game, I think.

You must be rigth about 7....Rb8 in the game Rybka x Hiarcs, never used in your
database by humans. But the openings in matches between engines are prepared
differently. For example, to an engine with a good hardware, sometimes it is
better not follow the human opening theory. Difficult for me to know if 8. Nc4 it´s
a questionable move, I would have much time to analyze the position with computer help.
Several programs play 8...Nf6, including Rybka.
In the game Junior x Rybka, Junior played 6. dxc5, This move is used by humans?
Junior made an excellent opening.

Re: WCCC - Rybka v Hiarcs Round 8
This seems like a Playchess cultivated move which is not really a very wise decision due to several factors. One is that on Playchess games are usually not more than 16 0 and another is that the Rybka playing probably has a different evaluation than the one that plays on Playchess and thus predicting its moves in inferior positions are difficult.
Having said that, it seems to have worked with Junior. They found a chink in Rybka's preparation and got it in a positionally lost position very quickly. Junior was not strong enough to get the point though and that is why Rybka is such an extraordinary engine.
