Recently made an update of the Bookbuilder program (4.2)
Now more than 900 thousand position in the default book.
It now gives a reasonable accurate overview of the 'best'
opening variations or defenses , after 1.d4! 1.e4 or 1.Nf3.
Add variation name possible again (it had disappeared
in the previous version).
The 'demo' version on shareit.com is a fully functional
version, working for 14 days.
