lol... 22...
Really? All-In?
OK... When you have 6 BB left in a tourney and the small blind plays a min raise...
If you think about taking 22 rather than AK then you are playing bingo not poker.
BEcause what kind of hand would have shoved before you or will call your shove?
With 22 you are a very slight favorite against 2overcards...
But against suited connectors you are already the slight underdog.
And you are in very bad shape against any pocket pair...
22 is a slight favorite against AK so in the long term, you should win more money with 22. However, in a single hand, I actually prefer AKo because even though it is a slight underdog, there are many ways that it can improve to beat 22 when you add in the straights 4 card flushes and counterfeit hands that AK can win with.
Have you considered that these ways to improve have already been added into the calculation that showed that 22 is the slight favorite? Why do you prefer losing 2% in the long run over winning 2% ?
