You might try reversing your strategy. Play ultra-tight for 30-40 hands and then loosen up and bluff at a big pot or 2. Unfortunately, this almost certainly won't work at a penny table, and even at higher limits only works against people that pay attention. At the microlimits, I really think you will do better by playing loose/passive preflop in late position. You can limp about half your hands CO and Button because the chances of a raise are lower and if someone does raise after you, you will know how many callers there will be before you decide to call that raise. Just make sure you only continue if you flop a great hand when you play crappy cards in LP.
