Live games at 1/2 are always soft. The game is so slow that people get impatient.
First thing is narrow down what a "premium" hand is. Some people think AQ is a premium hand, I do not.
Personally, I would take my time and watch what the betting pattern is. Are people always raising 10x the bb? Do they call 25bb? This will let you know what to bet and not win 3.00, but narrow down the field.
Then I would wait for a premium hand. AA, KK, AKs, QQ, JJ, 1010 is about what my range would be. Get some good music.
Once I won a pot or two and got a feel for the table I would start expanding my range using "their" money, not mine, to include things like AQ, AJ, A10, KQs, KJs, ect...
