no real reads or stats, initial raiser raises perhaps a slightly wider-than-average range. PF 3bet is standard for me. i want to take it down and avoid playing AK multiway OOP. i understand BU probably calls/raises with anything that beats me and folds out anything i beat (i'll assume his range is 99+,AK,AQ and that he knows not to setmine with such a high % of effectives in the pot pf) . i just cant justify 3betting and taking the initiative pre then c/f'ing over 3 streets. if my assumption is correct, that he calls flop bets with with TT,JJ,QQ in this hand (or any picture overpair on a flop in any other hand) despite the majority of my range being AA,KK,QQ, should i bite my tongue and c/f AK here, making sure to exploit villian when i do have AA/KK?

if i do have to bet, on the flop or turn?
