If you want to be completely scientifically about, it is best to run two control
tests. One with a prepare opening book with brilliant moves, and another one
without it. Control test 1 will use the brilliant modified book, and play
against engines without this new modified book. Control test 2 will use the same
opening books without brilliant moves used by all the engines. This will tell
you if such brilliant moves are harmful or not.
