The check raise implies a strong hand. I don't think he has a weak Q. You don't c/r with a weak queen here. The line he takes is what a good strong player with 2 pair (big blind special)would take (Probably bottom 2 pair). I don't fold to the C/R because I don't want to appear THAT tight. I do fold to the turn bet though. He either has Queens up or a boat. If he pulls a lone 7 out of his bag, God Bless him as I will be stacking his chips before the night is over.
