Way ahead or way behind?

[pokerjo22]

So normally I'd have check-raised the flop, but after a moments consideration I decided to play the hand more passively. With no draws on the flop I decided I would get more value from the hand if I was ahead by allowing him to bluff at me, and save bets if I was behind. Was this the correct play? Villain in this piece was 18/3 but I only had 40 hands on him.
