AK again - anyone play it different?

Good evening. Can anyone see a fold on the turn? Any other way to play it?

I would 3-bet the flop and lead the turn if he doesn't cap. Your out of position and he could be going for a free card here. After he 3-bets the turn I have doubts on being ahead, but I don't think I could fold. I don't understand why he wouldn't raise hands like A5, A6, 55, 66 pre-flop from that position. It's almost like he limped AA or AK to try and get action.
