Probably being the operative word. :-) That is what I would do as well. You do
need a large amount of games to get a really meaningful guide. The problem is
that it is a lengthy way to find out. If you try the same opening with different
engines it can become quite an interesting pastime. Here is an ancient example.
My main thought was that non commital, somewhat universal openings as books
might be very useful.

The Nimzowitsch is not one of those, this much is certain.
