Tight early, only play high pocket pairs and see flops with like AJ+.
When you get down to 4-5 people or 100/200 blinds open up your range to almost anything from position. If you folded to get to this point your stack is probably still pretty healthy, go after people with up to a 3000 stack size with 1500ish stack, and only from position like the button or cutoff.
When there are only three people left there will still be very tight play, if you still only have around 1500 you're going to have to take a chance and double up somewhere, stealing is less effective but still possible if you have the stack for it. If you're around 3000 you should still definitely be stealing, people will fold away if you threaten their SnG life.
