Of course there is some strategy involved, since you need to decide, when to push and when to fold. But even so its most likely not possible to beat the rake, as others have already said. The reason for that is, its kind of limited, how big mistakes other players can make in a format like this. So as an alternative to slot machines, its ok, but not if you are trying to make money from poker, or for that matter get better. Even a hyperturbo SnG is more complicated than a 10BB push/fold cash game.
