Interactive Deep Analysis (IDeA) With Rybka Aquarium 2010

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.
