I would consider the God/no-God choice to be one of those things, since the choice presumably affects your life (and your forever, according to most religions).
Keep in mind, it's not just a "God/no-God" question. If you conclude in the affirmative, you are then faced with the follow up question, which one?
Sticking with your poker allusion, it seems to me that the best choice would be to go with religions that don't claim to be the only right one. Christianity means putting all your eggs in one basket, it seems to me. No, the logical choice would be several of the pan-theistic religions. Keep your options open I say. That way, if only one of them is right, at least you shouldn't get bad marks for having chosen the wrong one since they don't really tie you down to one anyway.
