Tournament Theory question

[David Sklansky]

It is the first day of a long 10K no limit tournament. All the players are about equal except for me. I estimate my chances of getting to 20K by playing normally is 60%. On the first hand a player pushes all in in the SB and unwittingly exposes his cards to me in the big blind (no penalty). No other players

The following question assumes that I am not concerned about hourly rate or getting into a side game if I go broke. It also assumes that the size of the blinds is insignificant. In other words, assume I am getting exactly even money if I call.

I should call if I think my chances of winning are

A. Anything over 50%

B. A bit less than 60%

C. Anything over 60%. Exactly 60% is a push.

D. A bit more than 60%

E. Significantly more than 60%.
