Rybka 3 UCI is the world champion of chess engines with a rating 3150 points ELO. The main developer of the program, international master Vasik Rajlich (Hungary), has inserted the algorithms of positional estimation into it which are as close to the chess-player's style of thinking as possible.

Here are some of the main features of Rybka 3 UCI:

* Takes full advantage of all Rybka features

* Leads all independent computer chess rating lists

* Rybka 3 UCI includes versions for 32 Bit and 64 Bit processors

Rybka 3 UCI is not a standalone program and works only in other popular interfaces e.g. Fritz, ChessBase 9, Shredder, Junior, Hiarcs, Chess Assistant, etc.

You can find a database with 460,000 games (2005 - 2007 years) in PGN format (for ChessBase, Fritz) and a demo version of Rybka 3 Aquarium on this disk.

"Why is Rybka so much stronger than all the others? My personal opinion is that Rybka's evaluation is better than that of her main competitors (and very different), while her search is of comparable quality (and somewhat different)." -Vasik Rajlich, Rybka developer. Opening book for Fritz interface - RybkaII.ctg
