After close to 20k hands of marginal winning at Stars full ring, I decided, largely on a whim, to try 6max. Honestly I'm glad I made the switch; for reasons I can't really explain I find the smaller tables more comfortable. Also I find the relationships between positions more directly logical. The stats above are my first 10k hands of 2NL 6max - clearly, the first 4k were far more fun than the next 6k, though I had no illusions that it was anything but a good run.
Like kousen, I would really like to move up - not for money, but to get away from mandatory fast tables. Playing at micro stakes is obviously to learn and improve, but it's very hard to try to start thinking about people's actions in terms of hand ranges when you have no experience doing so and very little time per decision. Between winnings and clearing bonus I'm reasonably rolled for 5NL now, and if my graph showed a steady winrate, rather than an obvious heater followed by a very frustrating breakeven spell, or maybe even if the order were reversed, I'd be happy going up - but as it stands I can't say if, after taking a shot and losing money, I could move back down and recoup. At the same time, the short time limit is really making me feel that I'm not learning much here. I've decided I will just try 5NL and see what happens, but before I do, is there anything here that suggests I will or won't fail horribly?
PS - I have no idea what is happening when I'm in the big blind, and while I'd love it to continue, I strongly suspect that it won't.
