We tried to keep all the major qualities of the previous ECO Volumes intact, but to make the book easier to read and browse through, especially when used as a source of reference. The material we gathered was so rich in details and nuances, so ultimately we decided to publish the ECO B Volume in two parts. We are positive that omitting any of the lines would be a terrible shame, so you will have the pleasure of reading and digesting the material in its completeness.

Finally, we are sure that the human touch should remain crucial, so all the members of the editorial crew gave their absolute best in researching, analysing, evaluating and suggesting lines of the greatest value and strength, thus allowing you to read the book and apply the lines in your own games with complete confidence.
