When people ask me what is the secret to success at the micros I often give them a simple answer. Bust the fish faster.
And it is pretty easy to see why this is the case. In today's poker games, even at the lower stakes, you often have a table full of regs and one bad player who everyone is keying on.
While you can and should be developing methods to beat the regs you are never going to turn a big profit against them. They just don't make enough mistakes for this to be possible.
So the best way to get ahead in poker is to get the fish's money faster than all of the other regs do. And luckily this is still pretty easy to do at the micros.
