I came across another ICM calculator a couple of weeks ago. It is called Sit And Go End Game Tools, or SNGEGT for short. You can perform the same post-game evaluations with this tool. In addition, the tool allows you to perform ICM calculations during a sit 'n go tournament.
The interface to the tool is a little funky. In order to get it to perform the calculations during play you must do one of two things: 1) select the table number and click compute, or 2) click on SNGEGT and then click with your ctrl key on the table. Once you get the hang of it, calculations are quick and painless. Basically, the tool will spit out a positive or negative EV difference number (the difference between EV for folding vs EV for pushing/calling). In theory, if the number is positive, you are "correct" in pushing or calling; if the number is negative, you are "incorrect" to do so.
So far I have only tested it with 9-player sit 'n go's. It does not work for multi-table tournaments, just sit 'n go's. And it will only perform calculations in all-in situations. On the last point, if someone before you limps or raises less than all-in, it will not perform the ICM calculations (which it shouldn't).
One more comment on the calculations. Just because the math says you are correct to push or call doesn't mean that you should. Likewise, just because the EV difference is negative doesn't mean that you shouldn't push or call. This is just a tool to help you with the math. Ultimately you should make your decisions on the specific situation at hand. I will cover this in detail in my Advanced Studies.
You can download the tool and evaluate it for free. However, the evaluation copy does not actually perform the EV calculations during play. It will just show you whether or not it can correctly read the table that you are playing at.
As to whether it is ethical to use a tool like this during actual sit 'n go poker tournament play... I will leave that discussion for another post!
