I agree. When I test versions and parameters, I am testing the engine, thus I
use an opening suite to annul the effect the openings might have on the result.
However, if my intention were to test the better program, I'd have to use the
book included, since presumably that is what will bring the greatest results. I
don't think one should eliminate the investment made to have a custom-made
top-notch book such as yours. A strong well-tuned opening repertoire is a
significant part of any master's or grandmaster's playing performance.
Possibly worse, is to use a book that is fine-tuned for an engine with a very
specific style (such as Junior 9), and impose it on an engine with a completely
different playing style. The book may give great results for the engine it was
designed for, but can easily give much worse results for an engine that is not
addapted for it.
