This is what I was talking about, you only get action when you are behind, and thus kill your implied odds.

Against an observant and thinking opp like him (not the maniac that some have understood my original post to mean -- aggressive in the sense that he wasn't a loose passive fish like most people at these places), wouldn't a smooth call basically define my hand as some kind of draw seeing that an overpair woulnd't want the two players behind to come? Opp told me that he put me on an overpair btw. Would I still have implied odds then?
It might, but if he has a big hand, it doesn't matter. You are getting odds to draw. If you raise, you are putting your money in bad if called/raised.

If he has the same draw, you have great implied odds.

And you bring up another good point, by calling you let the other 2 players in the pot as well. This is good for you, you are drawing to the nuts.
