Yeah I would call it off exactly what Patrick said... not really icm considerations when there is still 40 left and you are the ss. .. play for the win imo, like u say not very often you are going to be in that situation for that sort of buy In but huge amount to winner.
Roughly thought I was even money to be an even money shot.
5/4 to be a 5/1 shot.
10/1 to be a 1/5 chance.
