What's your line here. Without a spade here I don't think I can afford to give my opponents a free card here, so I'm opening 1/2 pot here. I think if I have the Qs here I'm more inclined to call this but without any spades I'm likely against folks with flush draws or a flush already? Any ideas what to do here?
