(I need to win financially. Lol)

I’m playing an underground free roll tournament for 3K first place. It’s very unconventional. We started with 10,000 in chips, the blinds go up every 15 minutes and the levels are (100/200), (200/400), (400, 800, (1K, 2K); etc. It should consist of about 30 players.

What leaps out to you in terms of strategy in this particular tournament. Anything jump out at you in how to attack this strategically?
