It is not a smart way to compete at poker. If you play every hand the same way, you will become too predictable.
At random intervals, it is best for you to mix up your play. If you are playing conservatively then loosen up every once and a while and play differently.
Note that this poker strategy is not best used for limit games with 7 or more players but rather for no limit games or shorthanded limit games (where bluffing and poker table appearance become more significant to the strategy).
You also don't need to change your style of poker game against weak opponents; they don't pay attention to how your style of play.
