Perhaps that's one of the reasons why the people who submit their chess engines
for evaluation would not wish to use the opening repertoire which comes with the
published version.

It seems that such competitions for ratings are, to some extent, competitions in
selection of opening book lines.

What is the answer to this problem?  How can the "opening book competition"
factor be removed?  Is it sensible to do this?
