This is an easy and obvious shove, and you dont even need a program like ICMizer to figure it out. AK is only a bad shape, if someone have AA or KK, and you block both those
hands. Sometimes you will get called by a lower pair, as happened here, but even then its not the end of the world, since you have lots of
equity, and there is an overlay from the blinds and antes. Just to give you an idea, who wide you are actually supposed to shove, I plugged the following scenario into ICMizer:
Tournament: 18-man on
pokerstars (40% for 1. 30% for 2. 20% for 3. 10% for 4.)
UTG (Hero): 9BB
HJ: 13BB
CO: 8BB
BTN: 15BB
SB: 20BB
BB: 11BB
Hero jamming range: Any pair, A9+, QT+, A2s+, K7s+, T9s+
You are supposed to be jamming with hands as bad as K7s or QTo, yet you question yourself, because you jammed AK, ran into JJ and lost. This is simply way to results oriented my friend
