No it isn't.  Again, have you _ever_ seen a serious human tournament were
players were forced to play a specific opening, regardless of whether GM
consensus says the positions are equal or not?

Of course not...

And you can't expect the programs to be put in the same predicament either.  A
program _might_ play all positions well.  It _might_ play some better.  I'd say
the author has a feel for that and assists via reasonable book line preparation
to avoid the positions where the program plays poorly, and vice-versa.  Najdorf
lines come to mind as very dangerous and many avoid them completely for that
reason...

Hiarcs might do well in _any_ position.  But then I know human players that play
any opening as well.  But not _all_ humans do that.  neither do all programs...
