Need help with game theory and bluffing.

[sharkscopeaholic]

Just read the ToP chapter of game theory and had some questions. Is this mainly for bluffing once all the cards are out? If not can someone give an example in nl hold em on a turn bet for example. This would be a considered semi bluff though right and not have much to do with game theory? Finally is game theory mainly just for draw games and not so much for hold em or omaha, stud? It seems like it would be most effective in limit games than nl.
