Only pointing at Eduard Gufeld And most of these games are a) not standing in your openingsbook b)not in your database While they are of theoretical importance. Ok I once made an openingsbook of 2550 and above players which was not to bad But far from perfect. the nice part of his games is that you have to put his games near Leonid Steins game to get a better Idea why they changed their mind by move ordering Then again a 1-0 or 0-1 doesn't say a thing neither. A player could have a good position make a blunder in time trouble and the position is in favour of the oponent. The only way to make a good openings book is with good anelyzes But I am sure chessbase did use some anelyzes to make the book folow a right path in most circumstances. Regards Marc
