Hier noch ein kleiner Nachtrag zu meiner Rezension über das Buch "Kotronias on the Kingsindian ".

Ich erhielt heute eine Mail vom Autor des Buches, GM Vassilios Kotronias. Darin schreibt er, dass er in dem Buch einen kleinen Fehler entdeckte, was er aber sogleich durch eine neue (und stärkere) Zugfolge entschärft hat. Er bat mich darum, diese Korrektur den Lesern darzulegen. Dieser Aufforderung komme ich natürlich gerne nach:

Dear mr Rieger

I want to thank you for your kind words on my work. To be honest, once I got a copy of my book I started reading it in search for mistakes. After turning the pages for several days, I noticed an error of analysis in Chapter 30, page 513, line B221) 15.Be3 ( Arising after the moves 1.d4 Nf6 2.c4 g6 3.g3 Bg7 4.Bg2 0-0 5.Nf3 d6 6.Nc3 Nbd7 7.0-0 e5 8.e4 c6 9.Qc2 exd4 10.Nxd4 Re8 11.Rd1 Qc7 12.Bf4!? Ne5 13.b3 a614.b3 Bd7 ) In spite of the fact that the continuation 11…Qc7 is not highly critical, but is rather included in the book for instructional reasons, I want to bring to the attention of the readers of this blog the right continuation: After 15. Be3 c5 16. Nde2 the right move is 16…Rad8! [ and not the suggested 16... b5? due to 17. cxb5! (I had only analysed 17.f4) Bxb5 (17... axb5 18. f4! is now bad for Black) 18. Nxb5 axb5 19. Nc3 planning a4 with a large plus for White due to the weakness of the b5 square] Play may proceed as follows: 17. Bg5 (17. f4 Nc6 is just unclear;17. Nf4 Bc6 18. a4 b6 is also ok for Black) 17… Bc6 18. Nf4 (18. Qd2 b5! 19. f4 Ned7 20. Qxd6 Qc8!21. Qd3 bxc4 is fine for Black who has ideas to press with …Qb7) 18… Qb8! 19. Nfd5 Bxd5 20. exd5 h6 21. Bd2 Nh7! (21…b5 22. cxb5 axb5 23. a4! is better for White) 22. Kh1 (22. a4 Ng5!?; 22. Re1 b5 is now unclear) 22… b5 This position is quite acceptable for the second player. Please, notify the readers of your blog for this correction, if possible. If I discover another error, which is not quite unlikely in such a large book, I will bring it to your attention.

Sincerely

Vassilios Kotronias
