2/4 i have AK scary board oop against passive player

[overAchiever]

How would you guys have played this? I was not too sure how to play it but I did not want to make the pot too big ... comments on all streets appreciated

villian was 27/2/1.5/1333


I think this is much tougher agaisnt an agro guy oop becuase I can count on this guy letting me get to showdown cheaper oop much more often ... (how would you play it if it was against someone with same state but that is aggro postflop?)
