ChessOK Playing Zone Screenshot (click to enlarge) Let’s come back to the past for a moment, when there were no Internet, no post services, no telephones and no other ways of long distance communication. That was a really hard time for the chess players who wanted to find good opponents. People had to play with the same players all the time and that was boring and even annoying.
The appearance of the modern post service exerted a great influence upon the chess players. It created an opportunity to play against the opponents who were hundred and thousand miles away! But this was an absolutely different type of playing chess, when a player had a day, a week or even a month to think over the next move, so that one game could last for many years.

Introduction to Tree Configurations

Rybka 3 Aquarium logotype Many chess software users are familiar with electronic opening books.
Chess players use them to study openings and build their repertoire, freestyle players use them for a similar purpose, and engine testers use them to ensure balanced positions out of the opening, etc.
Opening books are one application of chess trees, but Aquarium uses trees for many other purposes and takes this concept to a new level with its tree configurations.

Game analysis with Chess Assistant 10

Buy Chess Assistant 10 In the two previous columns we examined infinite analysis with Chess Assistant 10. Infinite analysis is a very useful tool, but it is best suited for analysis of a limited number of positions. One of the drawbacks of infinite analysis is that as soon as you want to examine more than one position it turns into a manual process where you have to make the decision when a position has been analyzed deeply enough and then manually move on to the next position and so on. For the improving player it is more efficient and useful to have all phases and every move of the game analyzed automatically. Each tournament game you play should be subjected to such analysis and stored for future reference after trying to learn as much as possible from the game and its analysis. Just remember that engine analysis is not a replacement for your own analysis. Always start by entering your own thoughts about the game and only then analyze it with Chess Assistant.

Rybka Aquarium FAQ

Rybka 3 Aquarium logotype Rybka 3 Aquarium is now available.
The June and July columns give a glimpse into some of the capabilities of this new software, and in April and May I interviewed the developers of both Rybka 3 and Rybka Aquarium.
