Not sure if this is good advice, but at 2NL 6max on stars I find the players to be really really passive. With aggressive bet sizing I was able to get a lot of players to fold when I had very weak hands. Often they wont fold to a pot size cbet on the flop but by potting again on the turn I was getting enough folds for it to be profitable.

I also found that often you think you might just be stealing too much from the CO and the buttton, and cbetting too much, but the players are so passive that its worth doing non stop.
