Betting for value?

[denouement]

A hypothetical scenario:

You are heads up, in last position, against a very tight player. The tight player bets, and you feel there is a 60 percent chance you have the best hand at this point. Considering that your opponent is tight, you know that if you re-raise him here, he will fold when you have him beat and call only when he has a better hand than yours. So would it then follow that it is incorrect to raise him? Would it be correct to raise him only if you suspect you're an underdog, in the hopes of getting him to fold a better hand? Or should you always raise when you think you are a favorite, but not enough of a favorite to slowlplay, regardless of how tight your opponent is? Thanks to anyone who can answer this ahead of time.

Raise when
1) You think you have the best hand but not enough to slowplay
2) You think you have the best hand but his hand is good enough to call
3) You think you have the worst hand, but your raise will make him fold

If you're Rippy, just raise no matter what and only fold if there is no possible way that you can make him lay down his hand.

It is always correct to raise unless you have nothing and are facing multiple opponents, or your hand is so marginal that you can't stand to call a re-raise.

If you are talking pre-flop and you think you have a better hand see the cheaper flop. If you have great read on your opponent and he puts up a big fight on the flop it's easy to get away from the hand later.

I was reading a starting hand chart, and it mentioned that in early position, without any raises before you, it's a good idea (in limit hold em at least) to put in a raise against tight players with premium hands like KK and AA. What I'm not getting is, if you're up against tight players and you're in early position, wouldn't you be more likely to get no action by putting in a raise with such a good hand? Wouldn't it be smarter to put in a raise against loose players who are going to call with their marginal hands? Against tight players, it seems more logical to slowplay from early position by just calling the BB. Is my thinking flawed here?
