Villain was a 15/11/1.4 over a large sample. So when a more passive type of tight reg takes this line, should I be ditching this? If yes, when?

i'm not folding.. i would call down..
does he have a history of donking sets? or sml pp's that miss- donk stat?
it's not your normal .50c into $2.50 bet lol...
does he ever bluff?/ call broadways oop?
is he aware of how you react to db's / your ATS?
play QQ/ JJ like ****? meh.. top top for less than a psb..
hero calls and mucks

looks like a fold to me, can't decide on which street yet though. Most likely on the turn.

history of earlier donk bets would indeed be pretty helpful because there are some players against which I'd laugh and just fold the flop and others where I'm happily calling down 3 streets against...

i can def see a case for folding - via 1AF over large sample size, (triple barreling nonetheless) but wouldn't you think it would be more of a fold on the river given that he picks up a great card to dub barrel - i.e. with AQ/ AJ's / fd's... idk.. i'm a pow / show me the one time you decided to triple bar. 44 / KQs lolz

I think I would fold the river but should have folded the turn.

We need to define the range he is calling a preflop raise with.

PREFLOP:

Vpip 15 (55+, A5s+, K9s+, QJs, A9o+, KJo+)
PFR 11 (66+, A8s+, KTs+, ATo+, KQo)

In my Oppinion he would call preflop with:
99-22, AQs-ATs, KJs+, QJs, JTs, T9s, AQo-AJo, KQo

FLOP:

Villain (99-22, AQs-ATs, KJs+, QJs, JTs, T9s, AQo-AJo, KQo)
Hero (AKo)

Against this range we have following percentages on flop:

Flop: Kd 6h 8s

Hero 84,961%
Villain 15,039%

Against a cbet on flop he will probably fold everything in his range except of:
VillainT(99-66, KJs+, T9s, KQo)

TURN:

VillainT (99-66, KJs+, T9s, KQo)
Hero (Ako)

Turn: Kd 6h 8s Th

Hero: 69,868%
Villain: 30,132%

If we assume that he would donk with this range we should call or raise (Hero 69,868%).
Depending on his stats I quess he'll never donk with that range.
I see him donking with: 88, 66, KhJh,KhQh, Th9h

In this case the percentages change a lil bit:

VillainT (88, 66, KhJh,KhQh, Th9h)
Hero (Ako)

Turn: Kd 6h 8s Th

Hero: 18,182%
Villain: 81,818%

Not that good .

Now we have to count the pot odds to decide whether to call or to fold and its evidently that we dont have the pot odds to justify a call. Since there is no possibility to redraw against his range we are not able to consider implied odds.

CONCLUSION:
All in all its obv that we have to fold on turn. Nevertheless I am not sure whether I could fold that hand.

"Villain has a set and enjoys bestiality"

set man, wiiiiiiii

i think it depends what thinking level villians is, if you think he's good fold it
