This isn't a hypothetical; it is the situation I will be in first hand of an upcoming SnG I'm playing. Let's assume I am BB, so I close the action. Assume only top 3 in the tournament pay out (with a typical payout structure) and we all start with 200 BB. Assume I have equal skill as other players. I have no information about how he will play after the first hand.

What range should I call with?

Edit: I believe I remembered how to do these ICM calculations. Assuming the payouts are 1st - $1600, 2nd - $1100, and 3rd - $800, I calculated that I should call with all hands that have at least a 54.7% of winning versus a random hand.
