This excellent program for learning chess openings includes theoretical material on every opening, a user-friendly and detailed classification of variations, a quick search option and an option for analyzing games and positions.

 

There are two ways of studying an opening: by looking through encyclopedic tables for chosen openings or variations and by moving along a Chess Tree displaying expert evaluations of a current position.

The material on openings is based upon about 500,000 of expert evaluations, 8,000 annotations to key moves by Grandmaster Kalinin, about 40 million of evaluations obtained in the course of analysis of key positions by Rybka program, and a base of 4.35 million games as of March 1, 2011.

A Rybka 2.3 program is integrated into the Chess Openings Encyclopedia with a possibility of simple connection to Rybka 4 or other UCI and Winboard engines. A powerful system of search according to player’s name, position, positional element, motif and material correlation is supported.

A test of opening mode will allow you to test your knowledge and your skill of playing in your chosen opening against the program and to obtain recommendations automatically.

 

Extensive Opening Databases
Openings Encyclopedia 2011 has all the data needed to support your opening studies right at your fingertips:

• A game database with 4.35 million games.
• Over 8,000 text annotations from GM Kalinin
• Over 500,000 expert evaluations of key opening positions.
• Over 40 million opening positions analyzed by Rybka.

Opening Tables
Opening tables are a powerful tool, which complements the move tree and present the theory in a familiar format. As the opening tables are dynamically generated, you can create a table for any position. You can add your own moves, variations and annotations to opening tables.

Opening Classifiers: Overview of Openings and Variations
Classifiers allow you to view the variations covered by Openings Encyclopedia 2011 through a Windows Explorer style interface. If you want to study a particular variation, just double click on its folder in the classifier.

Tree Display
Openings Encyclopedia 2011 also uses position databases, which has several advantages over traditional game databases. A tree representation gives you an overview of the current positions, which moves have been played or analyzed in the position and performance statistics. The tree catches all transpositions.
