The thing is that Crafty is open source. I can see everything Robert does, but
Robert can't see everything I do. This is pretty much true for any other amateur
as well. Because of this, I *know* my program has at least the knowledge
of Crafty, and quite a bit more as well. I assume most top amateurs have at
least taken a peek at Crafties code as well.

But that is plain knowledge. At least (if not more) as important is tuning
and debugging. Here, Robert has some 20 years of experience. I have 2.
The tuning of Sjeng's knowledge isn't close to the level of what Crafties
is, and as a result, even though I have more knowledge and a better search,
I was (am?) weaker.

Wow, that is amazing.
