First Multi Table Tourney

[Cashcow]

I'm playing in my first multi table No Limit Live Tourney in ywo weeks. I have played many single table tourney, live and online. Just wanted to get some advice on any difference I should make in my playing (general play).
It's an $80 buy in, unlimited $50 re-buy for the first 90 minutes. Guarenteed $25,000 payout (1st place $15,000)
Any advice would be appreciated, thanks in advance.

Take advantage of the rebuy.

Ultra Aggressive, sure -- but tight, nonetheless.

In my multi-table experience, I find that people see "all-in" as a bluff, and will call it... and usually be right. If you're attempting to buy the pot, don't go all in -- just overbet a bit. Over the series of betting rounds, if you don't provoke them to fold, you'll at least have an idea where they stand. Anyone with a big pocket pair, who's normally not a bluffer, will re-raise. All-in, in that instance, would be overkill... and cost you a lot more chips than necessary.

Thus, play Ultra-aggressive... in a sensible way -- as well as fairly tight -- and you should be alright. Keep to the good (or mostly good) hands, and bet the hell outta 'em.
