Also, given the pot odds you would need to win about 70% of the time
Its 2,14$ for Hero to call off, and if BB fold, then pot is going to be 4,82$. 2,14/4,82=0,444, so Hero need 44,4% equity. In reality he need a bit more in a cash game because of the rake. And in a tournament he need more because of ICM.
We can use Equilab to calculate, when this call is profitable. We start with the worst case scenario, which is KK+. AKo has 18,48% equity against that range, so calling is obviously terrible. Against JJ+, AK AKo has 39,78%, so still not profitable but a lot closer. If we add TT and AQs, then AKo has 42,87% equity. Getting closer but still not there. If we add AQo, then AKo has 49,18% equity, so now a call is profitable but not massively so.
So its one of those, where unless the opponent has a funny hat on or something, there is nothing wrong with just folding. A lot of players might not be willing to fold hands like AQ, AJ, KQ to a 3-bet, when they have position, but usually they are just going to call rather than 4-bet jam it all in for 100 blinds or more.
