Why would you use bitboards for generating moves?  i.e. at some point you have
to get a move list from your bitboard patterns?  If so that involves some
sort of looping?  If so then I can generate chess moves with a simple loop
i.e. move the rook right one square I just add one to its position.

I can understand using bitboards for evaluation instead.
