I normally play 2/4 limit ring games, and i like to once and a while play some tournaments. However i'm very confused as to how profitable they are. It seems like you have to make the final two tables to really recieve a good pay out. I've played in a couple of the $11 PS rebuys and it just seems that so many players are just playing like its craps since its unlimited rebuys and there becomes so many chips in play. I guess I'm just lost as how to approach these tournys and looking for any beginner advice. Do many people here like to play in rebuys, add ons, regular tournies, etc.
