strategy advice for today!!

Ok I need strategy advice. I'm playing in a LIVE freeroll today that has a total prize pool of 7400.00 and pays the top 20 and first pays 1700.00. you earn your starting chip count by the amount of hours played the month before.

I believe there will be about 35 to 45 players. so here is my question and would like to hear what you would do.
I'm starting with 1400 chips and the chip leader will have 5600.
there will be about 10 folks with less starting chips then me.

Do I play super tight and only play premium hands and play for 20th.
Or do I play Very aggressive early and try to accumulate allot of chips.

What would you do ?

The blinds start at 25 - 25 and go up every 15 min? What are the thoughts of the great Poker minds here at Weston!
I will be leaving at 1 as the freeroll starts at 2pm today
