One of the biggest changes in Rybka Aquarium 2010 is the greatly improved Interactive Deep Analysis (IDeA). Many players were happy with the possibilities offered by IDeA in Rybka 3 Aquarium, but I’m afraid that it will look like a dinosaur compared to the new version. It provides better automatic analysis and much more effective ways to control the analysis process and the shape of the analysis tree. I’m sure that many serious players will find that the new and improved IDeA is an essential tool to stay competitive.

Rybka Aquarium 3.2 has been released with several interesting enhancements. Some of them have been described in my recent ChessOK Cafe columns and, as usual, the Aquarium FAQ describes many of the new features. In this column I will show a few examples that should help iBook authors better understand some of the commands available to them. I assume that the reader is familiar with my two previous iBook columns: “Interactive Chess Books in Rybka Aquarium” and “Writing Aquarium iBooks – Introduction”.

In February 2009 I described a new feature of Rybka 3 Aquarium, Interactive Chess Books or iBooks. At that time the tools for creating iBooks were rather primitive, but a new version of Aquarium is expected soon and improved iBook writing tools are among the enhancements. In this column I will show you the basics of creating iBooks – enough to get you started writing your own. Just keep in mind that there are a many features that I only mention briefly, or skip completely, including some that are quite useful for larger writing tasks.

Based on the experience so far, we can see that iBooks are suitable for both small and large projects. You may prefer to use iBooks for your own personal annotations, for presenting tactical exercises and other training material, for web publishing, for preparing forum posts, etc. It has also been used successfully for jobs such as converting a 200 page chess book to iBook format.

This means that the whole ChessOK training catalog will be available for Peshk@ upon its release.
