My main goal when playing micro stakes cash games online has always been to beat them for the highest possible win rate — to crush these stakes. I am not interested in just squeaking by and relying heavily on rakeback in order to turn a profit like many regs these days. I want most of my profits to come directly from the tables instead.
The great thing about having a massive win rate is that you will have many more winning days than losing ones. In fact when I used to mass multi-table the lowest stakes I would very rarely have a losing day because my win rates were so ridiculously high.
