I've played up the 5$ and 10$ level six max super turbos, very weak play at 5, and not much better at 10. The thing is, you can just get a bad run of games and completely destroy your BR.
Early: Wait, watch. People get out fast. Stay as tight as possible... you start with 300, try and stay above 200, fold equity is very important.
Bubble: It gets here quite fast with the blinds. By now you should have a rough sketch of your opponents tendencies... steal as much as you can, bully the player(s) with medium stacks. Be prepared for some really terrible play.
ITM, heads up: Only two people cash, try your best to win, but honestly its a crapshoot heads up, either you have similar stacks or you're an underdog. Very rarely are you the bigstack. Bigstack is the easiest to play, underdog is hardest...
