villain was 27/12/1. the only read I had was that he calls TPTK on Fflop and min raises 2pairs on turn (if hits on turn).
Is this standard?

How many Tx hands does he have here?
His line doesn't look like a bluff.

Bet more on the flop next time.

FLOP: I bet only 3/5 pot as I was not worried about the flush with my Kc.
My line looks like 99, TT or KK with 1 club or QQ/JJ.
His line up to RIVER was Nutflush or bluff (counting the T high flush).
Against nits I sometimes took this line to put them off a T/9/8 clubs or maybe a set. Once they check river OOP they are saying I will fold to your RIVER bet.
Is my reasoning way off?

I probs fold river although that's ridic exploitable I just think this is Ac so much.

Just thinking about it, with villain's AF of 1, I have to fold this RIVER! With a bit more aggression that a case can be made for the bluff.
