Go up one level in this thread



It sounds for me that Alterman created the book for Junior overnight. Of course
they simply used his name to advertise the program. But unfortunately he has
done his job very badly. At least he had to spend another 30 minutes to delete
girls under 10 games from the database. I think everybody who has a ChessBase
can do a better job. And I reckon a 120 Mb or something book is too small for
such a progran as Junior-6. I created a book for myself and it is bigger then 1
Gb. And of course there are no girls-boys games. And I can't imagine how could I
play without this book in the world level e-mail tournaments.
