Hold em? What limit?
If you are talking NLHE, which I'm pretty sure you are, its best to sit back and wait for monsters until the blinds hit 25/50. Some people I know will not play any hand other than AA,KK,QQ in the early rounds. By playing this way, you build a very tight image that you can try to exploit once the blinds start to escalate and it becomes easier to steal with a 3xBB raise.
