Hmmm... this is without any preliminary move scoring, which runs at
approximately 2M/sec, but it _is_ a slow scoring routine and would be a bit
faster if I put some of it in the move generation routine instead.  I guess that
would take it down to about the same speed as yours and everyone else's.

I don't do any hash updating either in the move gen as I do this in a kind of
strange way later on.  It _does_ include updating material counters however.  I
could include a little score calculation in the move gen which would make it
quicker overall I suppose....

Cheers,
