Overbetting in texas holdem?

There are some spots where over-betting is a great way to get action, but for the most-part i just don't like doing it all that much. It has to be a very specific situation to do. The one place i like to over-bet the pot is where i flop a good hand like a set, and i know that the other player has top pair with a good kicker. This is a great spot to make a nice over-bet, since most times you will get re-raised by the other player. Oddly enough i don't ever over-bet when I'm on a bluff, i will even sometime value bluff, this is where a scare card hits on the turn or river and you make almost a value bet. But i only do this when i know the other player is weak with 2nd or bottom pair, when scare cards hit, i just love to just value bluff at the pot, the other player knows he can't beat anything but a bluff. But the over-bet can get you some calls since it looks like a steal, but the 2 things i hate about over-betting a good hand is that one, you may loss your fish, and number two, you may get called or even worse you may get re-raised. So you have to be careful in how you use this weapon.
