Rybka 4, news, tests & results

It looks like Rybka 4 is to be released, this discussion could gather the news, tests & results in matches of this new version against Rybka 3 and other engines (thinking about Stockfish 1.7.1, Naum 4.2, Fritz 12, Shredder 12, Hiarcs & engines that are "possible" clones of Rybka: Firebird 1.2, Ivanhoe, RobboLito, Ippolit & so on)...

Well, as it is possible to pre-order it at Chessbase & Chessok (Aquarium), I guess it should be released soon!?

The author of Rybka (Vasik Rajlich) said the first part of may...

Bad assumption, he has not kept a date in 2 years

...and he probably has much more to do this time to protect his source code & make an engine stronger than its possible clones... so we'll see :)

but its not actually being released either right? Its just they send you some online server login password bs. Its not a real engine this time around.

I was under the impression it was being released as normal, but there may be a stronger version held in reserve for the online thing.

By the way it is stated here http://www.chessbase.com/espanola/newsdetail2.asp?id=8300 (article is in spanish) by Cheparinov that Topalov's team had access to Rybka 4 during preparation. Also new Rybka opening book author, Jiri Dufek, was on Topalov's team.

This was posted in the Hiarcs forum by Harvey Williamson:" Now it is all over it is time to share a little secret. The day before the World Championship final in Sofia started I had a conversation with Vishy's team. For the duration of the match they have had access to my fast 8/16 core machine as well as all my databases and Hiarcs opening books. Also, of course, all the engines on my machine. I Hope this managed to negate slightly the fact that Topalov had access to the latest Rybka on its Cluster for a few months leading up leading up to the final."

you know an interesting thing i've noticed by listening to these post match interviews with Anand...

He is saying he expected Topalov to switch openings alot and not be so persistent. I wonder if Topalov was so persistent because he had Rybka 4 and he knew Anand did not.

This is for the single processer version I think. So will wait for the multi-processer version.

Topalov used Rybka 4 before the match

"(...) the team of Veselin Topalov would have spent 100,000 Euros to secure a 112 core computer cluster, with the latest Rybka 4 program exclusively reserved for their use until the end of the match."
