Hero calls...I'm guessing your two pair is good here 1 in 5 times to justify the call.

I cannot see raising and folding to a reraise. If you raise, you risk two bets to win the 5.5 in the pot. If you raise and he's some numnuts who thinks his aces and threes are a great hand and reraises you fold without seeing a showdown? I don't think this is the best play.

Yes, sometimes the villian will have a ten, other times he will have hit the runner runner flush, and sometimes you'll call and win the pot wondering what on earth caused this person to bet. Remember we are not playing against rocket scientists at this level (well, if they are, they can't be good ones). You have two pair which will win a certain percentage of the time. My personal guess is that it will win 1 in 5 times to make it worth a call.
