Go up one level in this thread
Thanks for providing some light on this subject, Jeroen. Up to now,
I was under the impression that a computer program's opening book
essentially contained moves taken from games actually played. It's
interesting
to see that on the contrary, there is a certain amount of "home
preparation"
involved... :-)
In Rebel 9, the book is rather shallow in the Center Counter Defense
6...Bf5 variation. Are there new developments intended for that line
in Rebel 10?
My best regards,
FB
