I'm the the one to apologize. Som facts: If you "compile" the source files, the Lunsen database, from: http://www.uib.no/people/pfvaf/chesslib/Lunsen.htm you get the real Lunsen opening book. The ready build CB-tree that I publised _is not_ the Lunsen opening book; the plain truth is that this files are from ChessBase, sold a few years back as ChessBase PowerBook 2000. No, doubt, a comparison of the book files from Lunsen and the PowerBook 2000 files from ChessBase show a 100% match. I am compering the files uploaded from the Netherlands by Lunsen to my FTP-server in Norway, with the (original)files from ChessBase. (Don't confuse the ChessBase 2000- with the Chessbase2002 opening book). I have informed ChessBase about our mistake. The Lunsen database is still available at Chesslib; the the openg tree that I published by a mistake as The Lunsen Opening Book is removed from the web- and FTP-servers. (I aborted all ongoing DL and made the files inaccessible last Sunday, 15 minuts after Harald informed be about his suspicion). So, my thanks's to Harald. Here are extenuating circumstances, but I am responsible the contents on Chesslib regardless of the source. To all of you that have DL'ed the book files, please accept our sincere apologies for the inconvenience caused by my mistake. Of the total DL of the Lunsen files, 68% have downloaded the database - these are OK, the rest have downloaded the opening book, please delete these files. I'm compiling a new set of files from the database; they are probably online later to day.
