I do not say it is the same

My point is that the result of List when it has no book against opponents that
have book is good in the infinite loop when the result of List when both use the
same book(nunn positions) are not better  and even worse.

I also do not know of tests when list used some external book and performed
clearly better than the results in the infinite loop when it is using no book
against books of the opponent.
