Flopped straight, no redraws

[Aisthesis]

While my initial reaction was call the flop, raise the turn, I think I really like raising the flop much better.

First, if he 3-bets, indicating freeroll, you can get away without losing an unacceptable amount. You can also still get away on the turn if a flush card hits and he bets into you.

Second, you force him to really have nuts with redraw rather than the other way around.

I really think raising the flop here is the best way both to use your positional advantage and to get away from the hand in case of doubt. If you wait to raise until the turn, then he puts you in, you almost have to call. If you raise on the flop, you put the pressure on him if he doesn't have either nut straight with freeroll or set with flush draw and you can still get away from your own dead-end nut hand.

Also, if I raise the flop and he checks to me on the turn, I'm betting again. If he bets pot into me on a safe turn, I'm then laying down.
