The Key Hand Poker Application creates a graphical layout which makes it easier to follow and review the player's betting actions than by using hand replay animations.
The example below shows a simple hand where the cutoff and button both fold, the small blind raises all-in. The short stacked big blind calls and the program confirms it is a profitable call over the long run with an ICM profit of $0.7. It shows that a win percentage of 41.5% is the breakeven point for the call to be profitable.
However, even though the aggressive big stack won the hand by hitting his low card on the flop, the big blind call is the correct play.
