Villian is 31/24 on a small sample. No other info.
Preflop and C-bet seem standard. Folding the flop seems nitty after the small raise.
Turn call I don't love but in-game my hand seemed to strong to fold with only 67s type hands getting there with the gut shot.
The river overbet jam surprised me. I was planning on calling all reasonable size bets on safe cards thinking he had enough missed draws to justify calling.
His preflop range is fairly capped with just the call. I discounted overpairs except maybe 10s. The only strong hands it seems he can have are 98ss that backed into a full house, maybe sets of 33 and 55. The only top pair that beats me is A9 but I don't see top pair taking that line.
I really wanted to call but chickened out and folded.
67 is double gutted and the only real draw, so the 4 hitting is actually a v bad card.
I don't understand when people get this sticky vs me in this spot. I think most good lags don't take these lines with their air because people get too stubborn with tpgk to make it profitable to bet turn/bet river, and honestly going that ballistic to get you to fold your K9 just isn't worth it.
For him check/call flop and bet river if you check through turn is a lot more appealing as a bluff.
So I like flop because I think some %age he would check raise air but turn is def a fold for me.
