First of all I would like to thank everybody who has commented on the book, both positively and negatively, though most of all objectively.

I would like to run a quick comparison and add a few facts that may have escaped notice. First of all, all the material, that was found in the original edition is in the second edition as well (with the exception of one main game for which the analysis was so flawed and that the actual relevance of the entire game disappeared, but part of it has been preserved in a note to another game), except more analysis, more annotations and more game references have been added to all of the games. In addition, all analytical errors (that I found) and erroneous comments have been corrected.

The number of pages in the first edition was 142, in the second edition it is 272, and the pages in the new edition are larger, thus more text per page. The number of main games in the original edition was 121, in the second edition it is 168. On a chapter by chapter basis, it goes as follows:

Ch 1: 1st ed 8 pages 9 games; 2nd ed 15 pages 10 games

Ch 2: 1st ed - 11 pages 10 games; 2nd ed 15 pages 10 games

Ch 3: 1st ed - 7 pages 8 games; 2nd ed 15 pages 11 games

Ch 4: 1st ed - 6 pages 6 games; 2nd ed 14 pages 8 games

Ch 5: 1st ed - 9 pages 10 games; 2nd ed 20 pages 14 games

Ch 6: 1st ed - 6 pages 6 games; 2nd ed 17 pages 11 games

Ch 7: 1st ed - 14 pages 11 games; 2nd ed 15 pages 12 games

Ch 8: 1st ed - 7 pages 7 games; 2nd ed 16 pages 12 games

Ch 9: 1st ed - 16 pages 15 games; 2nd ed 35 pages 21 games

Ch 10: 1st ed - 4 pages 4 games; 2nd ed 20 pages 13 games

Ch 11: 1st ed - 13 pages 10 games; 2nd ed 22 pages 14 games

Ch 12: 1st ed - 8 pages 6 games; 2nd ed 14 pages 8 games

Ch 13: 1st ed - 11 pages 9 games; 2nd ed 25 pages 14 games

For those who are counting the games, the remainder to each total can be found in the introduction.

Are there things that could have been better? Sure, some have mentioned the issues in the first edition regarding the Reti with 1 Nf3 d5 2 c4 dxc4 or for that matter 2...d4, both should probably have been covered in better detail, but in general I feel I have added the majority of the new material where it was needed and where the developments in the theory and understanding of the particular information were more significant, such as for example the chapter on the Hedgehog, which grew from 16 to 35 pages.

There is a bunch of original analysis, some improvements and refutations of existing theory that hasn't been presented elsewhere.

I am open to all criticism, but as mentioned above, please let it be objective and relevant, and if you feel something could be done better, please be specific so that it can be corrected for future editions.

Thanks in advance for your input.
