Effective Stack calculation problem

[Mohinder]

This is a very common situation in Spin & Go tournament:

          BTN 12BB ---> Raise 2BB
            SB 17BB ---> Fold
(HERO) BB 15 BB

In this situation the Effective Stack when it is the bot's turn to act is 12BB.
I'm not able to define the correct value of the max opponent stacksize to compare with Hero StackSize because:

- if I use MaxOpponentStackSize this value is 17BB and Effective Stack is 15BB;
- if I use MaxStillToActStackSize this value is 0 because there are no more players behind Hero;
- if I use MaxCurrentOpponentStackSize this value is 10BB because it takes in account the raise preflop, and Effective Stack is also 10BB.

I'm almost sure that I'm missing something.

Thanks in advance for the help.

All you can really do is combine MaxCurrentOpponentStackSize with amounttocall and/or potsize to make your decision here.
