Preflop I play 3bet/fold from the SB with a linear range and standardly 3bet ATs here.

On the flop my first thought is that is that the board connects rather well with quite some of Villain's holdings but that I have a severe range advantage (I have AA, KK, QQ, AK, KQs, 88 whereas Villain should only have KQs and 88 here) and that I want to bet this flop a lot for value. When thinking about which possible bluffs I want to back my value hands up with I quickly thought that ATs with an overcard, a straight draw and backdoor flush draw might quite possibly be the best bluff I will find here (maybe together with JTs) and decided for a bet.

On the turn I clearly don't have a value hand and also don't want to turn my weak top pair into a bluff. I don't think I am ahead once Villain bets and I am mainly calling because of the price as I can still hit 5 outs to two pair or better, 4 outs to nut straight and since maybe there is a small chance he was floating with smaller suited aces.

I somehow feel uncomfortable with any street here apart from preflop but I also cannot convince myself of any alternative line... Greatful about any comment!
