Interesting.
I limp all hands but JJ-AA from utg whereas here im raising AK in mp. If he comes over the top with JJ (all in) ill fold no problem, if he reraises ill call to see the flop and on that flop im commiting my chips hoping im not up against KK or AA.
As for pushing AK, iwouldnt do it, especially here when i'd guess a higher pp . I'll take the JJ most days against your AK push.
The play isnt foolish/fishy but you need to rely on a post flop read and to understand that if you miss here post flop you inevitably have to put it down to his post flop aggression with the made hand.
AT least give yourself the chane to put the hand down post flop rather than commiting preflop with an unmade hand.
