Hand

Hi.

Villain is unknown: I don't have any stats on him. Pre is standard, especially due to the open sizing.
My first question is: should I be raising the turn, to protect against some random draws? Or the flop is dry enough, so I don't have to worry about those things.
My second question: Is there any way I can get away from there on the turn? There are a bunch of hands, that he can have here that beat me, like 77, 65, A5. Would you do the same thing if you had this hand?

Regards.
