When I built my deck, I used pressure treated deck boards. They were quite wet when I purchased them. I clamped the hell out of them when I attached them to the joists, to get them as tight together as possible. I now have gaps as much as a quarter inch along most of the planks. If using pressure treated lumber that isn't kiln dried, I would not leave any gaps when laying down the boards.
