just my opinion, but i would think you should play more than power hands, especially in ep, to insure your premiums receive action.

if you run 15/6, or even less, i will not play with you unless i have a pp, maybe AK. when i hit my baby set, then i float on you until you give me your stack, as you most likely cannot detect a floater until its too late...and even then you hold overpairs in too high a regard.

however, if you open up a bit, to say 20/9, i will payoff your premiums more often out of disbelief, knowing you can raise it up with KTs from ep. i will inevitably think my KQ is good to your AK/AQ, and then its MY stack that goes bye-bye.

dont take this too literally, as this is a general answer to a question that we can all overanalyze to death with specifics.
