Do i get away from this?

[Knekk]

Looking back its quite clear to me that I was behind, but sometimes some villains will call on the flop hoping I was raising with a high pair, and they will represent an ace if I check on the turn. In that case i should have checked but i felt i wanted control in the hand.

What should i have done different to get more information?

He did infact turn over the stone cold nuts.
