When I put the same situation into three different ICM calulators, I get three different results (ICM Trainer, sng Wizard, and HoldemResources.net).
Situation:
CO: 2000 chips
BU: 2000 chips
SB: 2000 chips
BB: 12000 chips
Since they have this feature, the sng wizard and holdemresources.net tools were told that the payout structure was .5, .3, .2
ICM trainer CO push: 17.9% 22+, A7s+, A4s, A5s, ATo+, K9s+...
sng wizrd CO push: 19.0% 33+, A2s+, A7o+, KJs+...
holdemresources.net CO push: 15.2% 88+, A2s+, ATo+, K9s+...
Which of these three, if any, follows the optimal strategy? These differences are significant enough to make a difference in ROI. How am I to make the correct play?
