Without a read I call the flop - a bet out of position into a preflop raiser regularly means at least top pair - if you knew he was a maniac or something you could raise, without that information you have the odds to call for your five outs to trips or two pair.

Turn is close but with the likelihood that you can raise and he'll call on the river if you hit the Ace or Jack you can still call.

Are you good one in ten times on the river? Probably not. I might call just to see what he had and take notes but you're almost certainly beat here.
