Let's see, I'm sure I've lost and won about the same number of hands with AK vs. JJ since they're both equal in value, almost. JJ has a tiny, teeny edge, but not by much. AK suited switches that edge back, but again not by much.I would say AK
I prefer AK, because it has a chance against QQ. Except heads up where JJ has a slight edge but it is basically a coin flip.I would say AK
A made hand preflop always has an edge. But you always have to take into account many other factors, position, number of calls and raises, stack depth ... You can list for a long time, but everything will depend on the specific situation. My choice is 50/50.I would say AK
