I dont like to play this kind of tourney, with the blinds growing up so quickly u dont have time to make a read against anyone. In my opinion the best thing to do in the beggining of the tourney is just play super tight before the flop and agreessive after the flop when u have at least top pair with a good kicker, another strategy that i try to employ when i play this kind of tourneys is going all-in with hand like AJs,99,TT,AQs; cause im sure that the pressure is so huge with the blinds growing up so quickly that some lunatic will call your bet with hands like A9off,A8off,KQoff...and against them u are a big favorite.
