I envisiioned that one would have to generate all the moves first to determine
which moves are captures.  You say to look at captures and killers first.  How
do you know which ones are killers?  (What is a killer anyway?)  Doesn't this
require that you generate a complete move list first?

I figure that bitboards are probably used to generate captures somehow, but then
later when you are looking at the remaining legal moves, how do you check to see
that you haven't looked at a move already?  At some point you have to sort the
moves?  If so then what method do you us to sort the moves?
