You know a thing or two about a thing or two, as the saying goes, and most of what you know is poker. You know how to raise from the button holding a monster because you know the experienced players in the blinds will assume you are making a standard button bluff. You know how to re-raise just enough on the turn to get your opponent pot committed so that they will pay you off on the river. You know how to bet at the board with nothing on the flop to buy a free card on the river. But do you know enough to not do all of this in a single game?
Using all your strategies in one game is a mistake, in most cases. You may approach fancy play like this: "I'll only do this once, maybe twice a game" refereeing to a fancy, risky technique, and then you keep careful track of when and how you do the tactic. There is nothing wrong with this idea generally, but it becomes a problem when you decide to do all of your "reserved tricks" at one time.
Say, you have been playing tight, sensible poker but still losing some chips. You are about mid way through the game and facing some upcoming blind raises that are going to kill you in short order. You have not tried any of your fancy moves yet, so you go for a preflop raise and fire three shells at a pot on a stone cold bluff. It doesn't work. Okay, well, you haven't tried representing a big hand when the board pairs, so do that next. That didn't work - before you know it you are going all in on ten five off suit because you fancied yourself out of your mid level chip stack.
Fancy tricks are fine, and they can come in handy - just use them sparingly, and don't try them all at once.
