The user interface on this program is identical to the one used in the French Defense CD that I reviewed previously. Of course, the primary difference is that this latest opening CD deals with the Sicilian defense. So I won't spend much time discussing the user interface for accessing the material on the CD, and will instead concentrate on the contents.
First, let's tackle the easy part, and look at some important statistics. This CD contains:
This CD is quite comprehensive in terms of its coverage. Not only will you find the most popular variations, like the Najdorf, Dragon, and Scheveningen, but you will find some of the not-so-mainstream, but popular variations as well, including the Closed, c3, and Sozin attack. The latter seemed to be a fairly popular choice way back in the days when I was playing this opening. Here is the total list of variations covered:
Each of the above classifier entries also contains a number of subvariations. What you won't find in the Theory and Practice database are some of the permutations of the above (for example, you won't find a specific text article on the accelerated dragon, but there are some accelerated games in the larger games database). So rather than list every single variation on the CD, I've put them in a couple of CSV files showing the ECO codes covered in the two game databases. You can download these here.
In addition to the above variations, there is also a "Rare" category, and I've taken a screen shot showing the variations that it covers, along with the corresponding number of games. As I mentioned in my French CD review, the material is very easy to access, because of the classifier shown above. And it goes without saying that you always have a browser pane available to help navigate among the open games, theoretical articles and quiz positions.
One thing I neglected to mention in my review of the French CD, is a fairly minor thing, but it is helpful to those not familiar with Informant-style notation. There is a summary page within the main classifier for the Theory and Practice database that contains a nice key to all the informant symbols that are used for annotating the games. This helps make the CD a bit more friendly for beginners.
My impression is that this CD has a little bit more material than the French CD, which is what I would expect, due to the greater number of variations that need to be covered. Both have about the same level of detail, and represent very good references for players of the black and white pieces

The program must be installed from the original CD, but you will not be prompted again for the CD (no invasive copy protection schemes). English, German, French, Spanish, Italian are all supported.
