Indeed! if we can see much more of this, then maybe that would indicate that
DB was really not necesarily superior to todays software.
  But we should also test if other programs would know how to avoid things such
as blocked positions etc. in the way as did DB in same positions, and if not,
then the very next upgrades of software might solve them, and, somehow, overtake
what Deeper Blue WAS.
