It seems that Artuto did specific preperation against specific strong opponents
to play lines that they do not like.

Note that I never claimed that this kind of preperation cannot help but I
thought that nobody takes the tournament so seriously to do it(I remember claims
that Crafty has 0 chances to win the WCCC because unlike CCT people will prepare
so I thought that this type of preperation are only for WCCC).

It is possible but I still think that book is unimportant for movei.

The knowledge of movei may change in the future and tuning a book to avoid lines
that movei play well is simply unimportant because it is possible that it will
play well some lines that it does not play well today and all the work to avoid
some lines is simply useless for the future.

If I have a strong engine then it may be important mainly not to avoid losing
games but to win games like the example that you gave for Zappa-Pharaon.
