200NL; chasing K flush paired flop

[Halv]

BB is 30/2.6/0.5 and has been seen making weak bets with AA on draw-heavy boards multiway before. He has also been seen check-calling flop and c/r turn with a set of queens on an AQxx board. Based on this I think he has AA/KK here.

Button is an unknown and could have anything.

Can I make this play?

like it on the turn because, AAc has to call and i think it's less obvious than raising to $80.

lead the turn for $80ish

lead the turn for $80ish

Why do you like leading an obvious flush? Deny drawing odds to someone with the Ac?
