Your observation that you don't think "the book is engineered as well as the top
contenders" sounds like an interesting concept.  I get the impression that
playing Genius with the Fritz book would not completely null out the Fritz
advantage because, I assume, the Fritz book is "engineered" for Fritz.  I
presume that this means that the Fritz book lines are selected to optimize Fritz
performance by covering up specific weaknesses of Fritz and capitalizing on
specific strengths of Fritz.  If this were so, then forcing Genius to use the
Fritz book would not be optimum for Genius because Genius's specific weaknesses
and strengths might be different from those of Fritz.

If the above is an accurate portraial of what you meant by the book being
"engineered," then forcing Fritz to play with the Genius book would be equally
non-ideal.

I wonder if a match between Genius and Fritz, with Fritz being forced to use the
Genius book would result in more equality in the win/loss/draw results of such a
match.  In other words, if the problem were primarily one of book engineering,
such a match would point this out.

Am I anywhere near close to what you were thinking?
