I have been told that even when you bluff you should have something. Your bluff is that you don't have the best possible hand that you want your opponent to think you have. Add that to the expectation that your bluff should be enough chips to commit your opponent and you should be able to steal the chips. I would also agree that the bluff shouldn't be a major change in your style of play. (So either be consistent with your play, or keep changing your play).

I don't see people bluff as much at ring tables vs. tournaments. Of course, I have not played many ring tables, so I can't speak from much experience there.

I couldn't figure out from the suggestions below if it related to the type of table you were at - ring, sng, mtt.
