HU with Huge Stack: How to Play?

[burgi]

Hi,
ok, this situation came up several times lately in my 30+3 SNG's at Party.
I was the big stack on the bubble and just destroyed my opponents on it, pushing any 2 because the other 3 were all kind of low on chips and nobody wanted to bust out in 4th.
Anyway, at one point on the bubble, the chips were distributed so that my 3 opponents all had about 400, and I had 6800 with 300 big blinds.
Ok, so then, the next person busts, and we're down to top 3. Then the next person busts and it's HU.
In HU, I have about 7400 chips and my opponent the additional 600.
How do you play in these situations with blinds at 150/300? Push any 2? become more passive and wait for a decent hand? Or how do you play?
I found myself having difficulty with that and even lost on several occasions eventhough I had such a huge chiplead.
Help appreciated!
