I think an article about playing a "range" of limits to maximise winnings and decrease losses when playing optimal/non optimal. I first came across the concept in this video http://www.cardrunners.com/poker-videos/13-scariest-small-stakes-leaks-of-all-time-przytula/ and I think it's something many micro stake players don't even think of.
My new approach is to start playing at 1 limit below my normal and then move up once I ease into the session and am playing well. If i'm continuing to play well consider moving up a limit above what I normally play while I am playing my A game, but if I feel like I'm starting to play sub optimal then move back down to a limit below my normal limit.
