I think this is a very important test suite.  It seems that many programs have
gone backwards on positional knowlege.  Or is it also possible that they have
now seen some hidden flaw?

I don't speak Swedish, but I would like very much to see the reasonings behind
each one of the choices.  Is there any translation of that magazine into
English?

Anyway, here are the CAP records for that test set (very few with optimal
answers):
