And that is a place where bitmaps really shines brightly. IE I can generate captures _just_ as quickly as I can generate non-captures. I don't have to cull non-captures or anything, after the fact... I just never generate them in the first place... 0x88 does great at generating everything. It loses its advantage and then some when you take generating only captures. I also can generate legal-only moves without doing in-check tests...
