flopped straight OOP

I don't like the turn check, he isn't going to believe the 4 helped you if you fire another half at the pot and will probably call with overcards anyway. The risk with checking the turn is that if he is on overcards he will fold to your river bet if he missed.

On the river as you played it I would pot it, if he has a queen he will at least look you up or may think you are bluffing and raise you.
