who are you? 
Do you pay for bugfixes?

Great, i d like to get you as my customer  ;D

most of the authors i know do provide an errata page and don't try to make money with their bugs. Ok, it's a old book. And ok, it seems not to be a clever idea to buy old chess books about openings. I've learned my lessons. I hope, the other lines with ! - moves are still playable. This !-Line is simply lost.

ups, so i 've to pay for the bug fix  I work as a programmer, I've to try this with my customers 

Hi Tony,

thanks for your reply. Hmh, i'm too stupid to find the old post. Are you back to Rfd1? The whole setup seems to have a very bad score. I can't find any win in my database (players > 2300 ELO), but quite a lot of nice losts  . After e3 there seems to be no exit from the road to a bad pos.

Hi,

i own the nice Kosten english book, but it seems to be a little outdated now. I'm preparing for a local tournament and my opp always plays the e5 line. I've checked the line (book p.48/49 and Tony gives 13. e3 a !. But it seems, that the pos after Rfd8, 14.d4 exd 15. Nxd4 Nxd4 16.Bxd4 c5 17. Bxc5 Rac8 18.b4 Nd5 19.Nb3 b6 20.e4 Nxb4! is totally bad for white. So the ! should be a ??

For those without the book (are there any   ):

c4 e5
g3 Nf6
Bg2 d5
cxd Nxd5
Nf3 Nc6
0-0 Nb6
d3 Be7
Nbd2 0-0
a3 a5
b3 Be6
Bb2 f6
Qc2 Qd7
e3 (!)(?)

are there any improvements for white?

thanks!
