This is a dilemma. The thing is most players mix up their betting patterns. If your always betting particular hands one way, players pick up on this and react accordingly, usually having a negative effect on your bottom line.
There is a best way to play every hand, but it is not as simple of an equation as it seems. When you call, what you call with, when you raise, what you raise with etc. really cannot be boiled down to a formula dependent on the cards you play. Its really about the people you are playing, and all the variables of skill, moods and personalities interacting, that decides what you do at any particular point in the game with any particular hand or any particular play you may have in mind.
A simple answer to your question is well don't play that way. Mix up your play so that you are not so predictable as that and you will have better results. However to give you a good answer could involve a lot of broad examples. Your question just cannot be answered with any depth otherwise. Also your questioned is partially answered in a lot of posts throughout the site.
Dissecting some hands to see if your bluffs are good or bad would really help you with this particular question, and asking about hands you played makes for great questions and answers within the framework of what you are trying to learn.
