At 5 BB I would take a lot of
hands to jam with but I will ignore the 5 BBs and answer based on which hand I like to jam more and the answer is AK suited. Reason is, If we are playing push fold we are really using fold
equity so we really are hoping no one calls and we pick up the blinds. In that scenario 72 off is just as good as any cards. However, we have to assume that sometimes we will get called and when we get called we are going to get called by the top range of hands. With these two hands, AK suited fares much better against the top of an opponent's range vs 99. Any 1010+ has a crushed with A9 plus broadways are flipping.
Take the range I just mentioned against AK suited and we have life and many times are good, we are only bad against Aces and Kings. The weird thing is 99 vs AK suited and 99 has more equity but against opponents all in calling ranges I would rather have the AK suited.
