Dadi Jonsson’s article on CT-ART: Mating Combinations

CT-ART: Mating Combinations is a new training course. The “CT-ART” label indicates that it is a tactics training course, but more importantly that it is of the same quality class as the original and popular CT-ART. The author of this new training course is Victor Khenkin, an experienced and respected chess coach.

As all new training courses, Mating Combinations runs in the Peshka interface as shown in the following graphic.

Aquarium 4.0.6 Released

The long-awaited Aquarium 4.0.6 patch was finally released at the end of December. This is a huge update, involving more than one thousand changes, some of them major.

There is plenty of information available on the Internet about the new version, including several of my columns from last year. I think it’s time to give a high-level overview of this new version based on what has been written about it since the first hints of expected improvements appeared more than six months ago. The changes in the new version fall into these major categories:

  • New features, many of which have been described in previous ChessOK Cafe columns. I know that many users appreciated seeing their suggestions being implemented in this version.
  • Usability improvements, including a more responsive user interface and a more streamlined implementation of several features. Again, these changes were often based on user feedback.
  • Major redesign of the internal structure of important components of the program. These changes are not immediately obvious, but affect the ability of Aquarium to handle large amounts of data, improve performance of some time consuming operations, reduce resource requirements, decrease start up time when there are many open databases, games, IDeA projects, etc. Language support was also redesigned making, it easier to translate Aquarium to different languages.
  • And last but not least, bug fixes.

Rybka Aquarium: Using IDeA in correspondence chess

I recently completed an informal experiment that lasted eleven months. During that time I participated in three correspondence chess tournaments. My goal was to evaluate IDeA as an analysis tool for correspondence play and see how it performed in a variety of positions that arise in real games, especially middlegame and endgame positions. I made limited use of various resources normally used by correspondence players, since I wanted the results to depend as much as possible on IDeA itself. Those self-imposed restrictions affected the results, but I think they made the experiment more interesting for users who are considering IDeA for correspondence chess analysis.

Rybka Aquarium: A Guide to Basic IDeA Usage

This column is geared towards the average user who wants to start using
IDeA (Interactive Deep Analysis) in Aquarium 4.0.6 (the official release will be at 30th of December - ChessOK Development Team). I will explain the basic
steps to begin the analysis of a selected position and how to guide the analysis
into variations of interest.

If you are new to Aquarium, I strongly recommend that you familiarize
yourself with other Aquarium analysis features, such as infinite analysis,
before diving into IDeA. In the following I assume that you already know
how to use a game database in Aquarium, so that you can create or search for
games and positions that you want to analyze. I also assume that you know
how to install and configure chess engines in Aquarium.
