Buying a stack.

[SkippingGoat]

What is the appropriate amount (in terms of the percentage of the prize pool) to pay for a stack in a freezout tournament? Assume the following:

There are 5 players and you will be buying the stack of a player that is leaving.

The stack is 10% of the total chips in play and is the smallest stack.

The payout structure is 1st: 2/3 , 2nd: 1/3.

The skill level of all players is approximately the same.
