Well ok, but I think you've misunderstood the idea behind the op, or perhaps I didn't explain it clearly enough. I'm not advocating a strategy where a beginner starts playing at levels way beyond their abilities or bankroll just because they found a higher-limit table with one bad player on it. Nor am I saying they should skip limits. Rather, what I am saying is that you should be focusing on finding good tables within a range of limits that you can comfortably play at (emphasis on comfortably) instead of just at the one limit that is the limit you're bankroll tells you to play at.

For a relatively inexperienced player that might mean playing between $.01/.02 and $.25/.50 LHE, even though they have only $150 in their bankroll and haven't played at $.25/.50 before. If they're careful enough to only join in soft games at $.25/.50 they're not only going to maximize their chances of making a profit at the new level, but they will learn how the $.25/.50 game differs from $.10/.20 in a much more gradual way.

That to me is a lot easier and risk-minimizing approach to learning a new limit than just waiting until you have the standard 300BB and then going up and joining five tables at the new limit one night. The range-of-limits approach is how I've learned $5/10 and am learning $10/20 LHE and it seems to be working for me, though to be fair I've only played about 100k and 20k hands at each of these limits, respectively.

I appreciate this idea may be a bit advanced for beginners but I understand that other, more experienced players read this forum as well. Also I think it is good advice for anyone, beginner or otherwise, for the reasons I've mentioned here and in the op.

If you are a complete beginner and have no clue about how to play, by all means stick to $.01/.02 or the play money tables until you get some experience and have read up on the subject. But I assume that even beginners have been doing some reading and are taking the game seriously if they are going to the trouble of looking at posts on FTR. That alone should make someone competitive at the lower limits of LHE imo.
