Ive played in a few home tourneys where the play/structure is similar.
C-betting with decent hands is key and just outplaying weaker players. If they think your tight you can get respect later on, or earlier. Or you just have to make a couple hands early on to survive later levels. Probably best to make moves earlier as people generally dont want to risk their stack early on and will give hands up easier, these small pots are great for your stack. Other people may not even notice the blinds creeping up on them and all the sudden they have 6BB left and just about crippled.
IMO- You know how big the blinds will get so theres no point in floating your way, the structure is designed to create action and get players eliminated. So I think your range has to open up to accommodate this style. OH I forgot to mention how position is everything too.
Maybe my advice is not the best since there have been people that disagree with me on certain things here. Everyone sees poker differently. Im just trying to give you an idea of how other players think.
