assuming you're behind and you need a boat to win, you're 8.75:1 against making one of your four outs. You're getting 8.5:1 pot odds. So regardless you're basically correct to see the river card.

Now the real question is, do you call the river bet. Personally, I still call because he could be betting two pair (or some kind of low flush/straight draw [img]/images/graemlins/confused.gif[/img]) in hopes you either didn't improve beyond just queens or that you were bluffing.
