I don't like the idea of getting used to playing different stack sizes at cash games. I would recommend studying and improving at 100bb or 40bb only. Preferably 100bb to maximise value, as it's going to be near impossible to churn out a winrate at the micros with 8bb/100 rake and fuck all rakeback on Stars.

I take Keith's point about people slow bleeding money with loose calls from the BB, but this is never a fold preflop at any stack size. If we only continue with flopped 2pr+ and flush draws on the flop, we easily have the odds we need. I recommend Flopzilla for looking at this type of thing.

As played, jam seems like the only (marginally profitable) option with this stack size.
