Chessbase Deep Rybka 3

Chessbase, who distributes the best chess engines (Fritz, Shredder, Junior, Hiarcs, Zappa...) now also distributes the little fish : Rybka 3 and Deep Rybka 3 are available.

Rybka 3 (by Vasik Rajlich) is the reigning computer world champion and should be at least 80 points stronger than the previous version Rybka 2.3.2

Did anyone test it already ? What about the improvements (particularly Monte Carlo Analysis in endgames) ?

Rybka 3 book with 3,387,966 positions (260 MB) is also available.

I think 80 points is conservative. Big disapointment is you must buy the New Rybka 3.ctg book separetly, Wayne

available? - not quite

Rybka 3 is not quite available yet. You could pre-order at Chessbase (if their website wasn't down) or at Convekta. But delivery willl begin on August 1 or August 4 depending on where you buy.

Rybka opening book

Wayne, Do you really mean MUST? or is it that if you want the super duper Rybka opening book, that is will cost extra, but if you dont, then you can just use any of the older opening books?

Rybka Opening book

Howdy Garvin, My bad I should not have said "must" meant to say " if you wanted Rybka3.ctg you must buy it seperately. Wayne

Rybka Opening Book

In fact I will share an opinion that I have become to trust. That is, even the best books offered have a very short life expectancy. Certainly less than six months with active chess players such that play on "play chess" and even here. Book lines soon become refuted by these centaurs and a new private book of theirs emerges. I will admit that such is the case with me here on Ficgs. I have/use recognized good books that are available, but have my own small book that I consult. Just an opinion and hope this shared info is taken in the helpful way I intended. So this would indicate that R3.ctg probobly is a great book, but against active centaurs will soon reduce its effectivity. Thanks Wayne

Rybka 3 "Human"

ChessBase just published a new article about new features in Rybka 3 that seems particularly dedicated to analysis with Rybka "Human". Among features : Shared analysis, Handicap book, Multiple variations, Monte Carlo Analysis and so on...

Now what can be reasonably expected in Rybka 4 ? :)

Rybka 3 encrypted

It seems that Rybka 3 would be actually even stronger that the commercial version of Rybka 3, Rybka team (V. Rajlich, L. Kaufman) explains that the compiled code was encrypted, as a consequence the engine would lose about 60 ELO points in that process.

A smart move by Vasik Rajlich to prevent his engine to be cracked by using simple decompiling tools. (ICE may help the most motivated though)
