I have played a significant amount of microstakes stuff, normally 1c-2c NL at CD poker. I play extremely tight preflop and play almost exclusively from late position. Hands like AKs almost play better than a hand like KK so I try and raise significantly preflop anytime i enter a pot. For example, if the blinds are 1c-2c and there are 3 or 4 limpers and I am in a back position I will raise to ~16-18c. This gets most of the rabble out although i will still get 1 or 2 loose callers which is great when you have KK. If too many people call your raises with your big pocket pairs (like 6 or so) you have to be extremely careful if you do not make your set. Also, I don't like to bring the maximum to the table. It is much more profitable to bring half the maximum or even the minimum to reduce your variance when the bad players inevitably suck out on you. Also, it makes calling easier because they can't put you to the test for all of yur money.
