PF raise is fine. Be more aggresive post flop with over pairs. Bet the pot on the Flop (.40cents) and again on the turn (.60cents)....if there is still someone in the hand by the river then chances are he has you beat. So either check and call if he bets a reasonable bet (he bet .40 cents thats only half the pot, i would have called or raised that in a second.) or fold if he bets the pot or higher.

OR even better make a blocking bet on the river by betting 3/4 of the pot or so (.60 cents again) and hope he only calls u...if he raises then u can fold.
