Don't think I don't like "speculation". this is (I believe) one thing that
will always hurt me when playing against other computers. I am just very
suspicious of positional scores > 3.0 as they are _very_ dangerous. I have
a few that can get that big easily. But they are _highly_ constrained to not
kick in unless it is almost certain they are correct...

As I said before, I would be perfectly happy at playing like a 1970's Karpov.
