You keep comparing Genius 6 to PCG 1.5 - that is not a very fair comparision
IMO.

Michael,
You have rasied some good points - 1. I forgot that I had Shredder 6 book
loaded. 2. I did not realize (or I forgot) that there was a better setting
than tournament. Things like that happen as you get older. In many programs
"tournament" is the best. My short test of the Shredder 6 book indicates that
Nc6 would never be played in response to 1.e4
On the other hand, the "wider" book may be more interesting to see how well an
engine plays out side the best book.
So for a serious match, I agree it must be played with "best" and the original
PF2 book.
Thanks,
Michael
