Poker Strategy - Changing Pace

Poker Strategy - Changing Pace:
One thing that most people do wrong, including myself at times, is play consistently. You may play your AQ differently sometimes preflop or when you hit an A or Q. You may bet a different amount (in No-Limit) or choose to jam the pot at a different time (in Limit). However, most decent players will be able to identify you as a certain type of player: tight-aggressive, very tight-aggressive, etc.
A way to help your earnings is to simply switch up your play sometimes. This way, when they're expecting that you're going to bluff, you bluff rarely so they'll call you more. Likewise, if your bets are usually for value, you start to bluff at the pot a lot. People generally won't catch on if you do this discreetly, and it can add more mystery to your play. "
