How do you play HU on PP?

[legendary loser]

I just started up playing SnGs on Party ($10 and $20 NL) again. When the blinds are 200-400 or 300-600 do you always go all in with any Ace, King or two pictures cards? In addition, what about hands like Q10, Q9, etc. I play about 10-20 SnGs a day and I'm not sure if I should approach this like a cash game where I should push my small edges because over the long term it wil be +ev. Or, If I should treat this like a tournament where the goal is to survive and wait til you are in a dominating position to put your chips in.

Thanks.
