Houdini 2 Aquarium
In an announcement earlier this month, ChessOK introduced a new member of the Aquarium family: Houdini 2 Aquarium. It’s actually a group of products comprising Houdini and Aquarium, available both in a single package and as separate products. As chess players know by now, Houdini is currently the highest rated chess engine and the new Aquarium version is an even better analysis tool than previous versions. Best of all, the new Aquarium version will be available as a free update for current Aquarium 2011 users. Read the rest of this entry »

Sending Games and Position to IDeA
In this column I describe various methods of sending games and positions to IDeA. In addition to (or instead of) letting IDeA choose positions to analyze, you let it analyze the positions that interest you. I assume that you are using Aquarium 2011, which has greatly improved support for sending positions to IDeA. Furthermore, I expect that your IDeA project is linked to a database game, as it allows you to send infinite analysis variations automatically to IDeA. For information on linking a game to an IDeA project, see IDeA Master Trees and IDeA Game Links. In general, I recommend linking games to IDeA projects instead of running the analysis from IDeA mode, as was necessary in previous Aquarium versions. Read the rest of this entry »

Introduction to the Aquarium Directory Structure

This month I take a brief look at the Aquarium 2011 directory structure. A general understanding of where Aquarium files are stored is useful for performing various tasks, such as backing up important data, and transferring databases and trees from one computer to another, etc. It also helps you to find the most appropriate place to store your personal databases, analysis trees, etc. within the Aquarium directory structure.

Aquarium Engine Matches and Tournaments, Part Two

After being preempted by the release of Aquarium 2011 for the past two months, we now continue our coverage of engine matches and tournaments in Aquarium.

Observing Games

We finished Part One by having a quick look at the following screen-shot of a chess engine game in progress:


We’ll have a closer look at this window now, starting in the upper-left corner.

There are two tabs at the top of the image. Observe Game is currently active, but Board allows you to set various options related to board display and move input. There are two buttons on the Observe Game tab.

Aquarium Engine Matches and Tournaments, Part One

Engine matches and tournaments got a very noticeable update in Aquarium 4.0.6. The “Match properties” and “Engine properties” dialog boxes were redesigned to increase consistency in naming and options. Several useful options were also added: ● Unified and improved dialogs for creating matches and tournaments ● Openings can be played from a PGN file ● Prevent unloading of engines from memory between games ● Display game count and duration estimate for a new match/tournament ● Tournament/match settings can be saved and play started later ● Engines can be added to an ongoing tournament ● The board can be automatically inverted to follow the stronger side ● Elo difference is displayed in engine matches ● The time used for individual moves can be displayed in the notation ● Number of endgame tablebase hits can be displayed in the notation ● The games are now stored in CDP (Chess Assistant) database format ● Asymmetric time controls in engine matches are tied to engine instead of color Read the rest of this entry »

Aquarium 2011. Part two

Last month I described several features in the new version of Rybka Aquarium of interest to the serious analyst. This month I’ll continue my coverage of improvements and look a little deeper into how users who prefer infinite analysis can take advantage of IDeA with minimal effort and without the need to study all the options available for automatic IDeA analysis.

HTML Export of iBooks and Games

The first free update of Aquarium 2011 has already been released and it comes with improved HTML export of both iBooks and games. There is a choice of standalone HTML pages that can be uploaded to a Web site or output suitable for inclusion in blog posts. Here is a screen shot of a web page generated from an iBook page with the new version.

You can play through the game by first clicking a move with the mouse and then using the arrow keys on the keyboard. Read the rest of this entry »
