There was a typo in my response.  "not quite easy" should be "now quite easy"
as searching over 1M nps will wrap the counter inside an hour.

Castling and EP really shouldn't slow you down, as you will skip that code
most of the time.  Just make the "should I do this?" test as efficient as
possible so that it doesn't impact you when you can't castle, which is most of
the game...
