Unlike other book makers I manually edit my books and check lines with Rybka engine and apply my own knowledge and chess ideas on which is the best move. Although I don't have it, in my opinion the book is also better than commercial Rybka3/Jeroen Book. When it was released it only lead 20 elo against nearest competitor (source) and I suppose the author has access to private rybka versions prior to releasing it. Mine leads by 50 elo using no private rybka engine in making it and best of all it is free! :-)

Although it is a hobby making the book does take some time and efforts of mine. And I think it is of a higher quality than some commercial books offer (powerbook, rybka3 etc.) and I am sharing it for free. If you think I deserved it you are free to donate some credits to me. Just click that donate link on the upper part of the site and you are free to put any amount you wish to donate. If you do, I can't promise but I might reward you. :-)

Thank you,
