I think I prefer the other one with fewer passes. While Gunnar's choice
makes sense to me (the position in the database is _not_ arbitrary, and
you could take that into account when fine-tuning pattern valuations),
the move comparison is clearly arbitrary. You would get it the other way
round in the same position just rotated around the center.

If we have such a situation, I'd rather prefer to have a FAIL in the
regression tests so that we can keep tuning for it, than silently
assuming we have solved the problem.
