The pgn-source for the bin-file is only at home. But if someone is interested, i can place it also on the ftp machine. But everyone should build their own book, therefore the new rock.pgn is there. With an extractor u can easily extract the games from the best 50 players of the world. For me it works well, maybe someone can post experinceces with the top50.bin. So I know, that my work is on the right way. peter
