I guess that general.ctg is the book that Fritz6 used in chessfun's tournament.

The results of this tournaments suggest that Fritz6 has a better book than
Junior6.
simple calculation gave the following:
Fritzbook+Fritz engines(Fritz6,Fritz65.32,Fritz5.16,Fritz4) 145.5 out of 280
Junior book+ Fritz engines(Fritz6,Fritz5.32,Fritz6old,Fritz4) 142.5 out of 180.

Fritz6old is probably better than Fritz5.16.

I have not Junior6's book but
I am not impressed by Junior's book.
I believe that people prefer the Junior's book only because of the fact that GM
is involved in the project.

I saw some of Junior's games and it seems to me that alterman did not work
seriously in the book

I saw a game when Junior had evaluation of mate against itself out of book.

Did you see something like that with the Fritz6 general book?
