Rebuy Strategy

[HoldemCrew]

What is the best way to play in Rebuy tourneys? I normally play very tight, patient poker and do very well in normal tourneys. I don't seem to do as well in Rebuy tourneys, because when all the crazy players go all in against each other, one of them doubles up, and the other one just buys back in. Should I be more aggressive?

Example Hand:
I had AK with about 1500 chips. I raised it from MP. A 800 stack goes all in. A 4000 stack goes all in, a 1500 stack goes all in. It comes back to me.. and I figure I'm of course against pairs and have far less than 50% chance of winning. In a normal tourney, of course no way do I play this hand. I laid it down, and the players flipped over AQ, AJ, and 99. Surprisingly the AJ won with 4 to a flush. (I would have won with the A of the suit...)

Is that a call I should concider in a rebuy tourney?
