I'm having trouble mid-game. I can easily open, I have some good openers, but I'm really struggling when it comes to carrying on the conversation. Obviously, I can't ask "when was your first period?" or "how do you feel about the Spanish Inquisition?". I know I can always ask "what do you do for a living?" etc. But how can I advance from that point? What are some good topics to keep the conversation going?
