20M nodes per second on a single CPU seems _way_ hard to believe.  The problem
is that in most cases, the move generator is far from being the dominant part of
the calculation.  In crafty, it is in the 10-15% range.  If you take that to
zero, you only run 10-15% faster.  Which leads me to believe that this is a very
optimistic estimate on overall speed.
