The Ac did not help your hand, it weakened it. It's very unlikely that villain would hold off on two streets from raising with a set on such a draw heavy board. I don't think you have fold equity against KT or a baby flush in most situations so I like a check in this spot. If he bets you have a tough decision: He's probably aware that he is betting into a probable 2 pair/set, making this a suboptimal spot to bluff unless he puts you on exactly KK. Honestly the way he played it looks a lot like some combo st/flush draw and I would cautiously check and reevaluate if he bets. I like your PF, flop and turn bets, although I might consider a C/R all in on the turn against a tricky opponent.
