Rybka 3 Aquarium (DVD) By Mark Donlan

The beta version of the computer chess engine Rybka (which means “little fish” in Russian) was released in 2005 and it was quickly apparent that it would be a contender as the strongest chess engine in the world. By 2006 it had a rating of 3000, surpassing other engines by as many as 200 points, and in 2007 it became the 15th ICGA World Computer Chess Champion.

Since then Rybka has had high-profile odds matches against a number of noted players. It won 4½-1½ against GM Jaan Ehlvest in 2007 and 6-2 against GM Joel Benjamin in a 2008 match in which Benjamin had white in every game and draws were counted as wins for him. Most recently, Rybka, ceding pawn and move in each game, scored 4-4 against GM Roman Dzindzichashvili.

Rybka 3 now has an estimated rating of 3150. All that Rybka lacked was an interface to call its own, but now a graphical user interface (GUI) has been designed for Rybka by developers Victor Zakharov and Pete Lupherenko. Rybka Aquarium is designed to take advantage of the full power of Rybka 3.

The interface is based on the Fluent design, which was first introduced by Microsoft in Office 2007. The first thing you will notice is that all menus and toolbars have been replaced with a single container that organizes Aquarium’s full feature set into a series of tabs. This container is known as the “Ribbon”. Read the rest of this entry »
