Sounds like World Tavern Poker, which is what I play.
I lower my starting hand requirements some, but generally play tight for the first couple of levels. If I'm going well, I keep playing the same way, otherwise, I'm pushing hard with hands like A 9, KQ, medium pocket pair. But, you have to push hard before you get below an M of 3, after that, you're going to get called no matter what you have.
I use my position and fairly tight table image to steal when I can, and if I have the pot odds to call, I go for it. If I have a strong hand, I push it for all it's worth. If I bust out, so be it. It's free poker, so you have to be a little reckless.
Since I picked up HOH 1 and 2, my win rate has skyrocketed. People are starting to hate to see me sit down with them.
