ChessOK Aquarium

ChessOK Aquarium is revolutionary analysis and database tool, combined with the strong chess playing engine, Rybka 2.3.2a (World Champion 2007). ChessOK Aquarium supports both UCI & WinBoard protocols, which are used by most modern chess engines (including World Champion 2008 Rybka 3). Interactive Deep Analysis mode (IDeA) is a new, unique and powerful analysis method. IDeA examines a position and then follows the most important moves automatically to create a tree of variations. It just keeps on crawling the variations in an intelligent way, adding more analysis, and never stops until you tell it to.

ChessOK Aquarium allows you to play chess both vs computer (chess engine) and real players:

- Huge database (3,700,000 games)
- Huge trees (30,000,000 positions)
- Three handicap modes, including predefined material and elo rating lists
- Support for Chess960/Fischerandom games.
- Blindfold and semi-blindfold games.
- Free online play at the ChessOK Playing Zone.

Aquarium offers advanced analysis functions, game commenting, searching, powerful chess trees, playing, databases and much more.

- Use Chess Informant style symbols, apply board graphics etc.
- Insert reference games from a huge database and endgame information from tablebases.
- Annotate a move or a position just once in a tree and you will see your annotations everywhere the same position comes up.
