[Closed] SH 0,5/1 K9 in CO

I like the way you played it.
I think C/C on river is suitable because we are inducing a bluff from hands like JT,QT or QJ (he coldcalled pf so he is probably a bad player therefore i think we can add those gutshots into his range).

I would bet the river. He coldcalled preflop and seems to be one of these SD-bound fishes. I don't think you will get bluffraised on the river, so it's b/f for me.

But c/c for bluff induction seems also nice to induce bluffs from gutshots. I have a feeling I'm too aggressive in these spots. Maybe checking is better?

I wouldn't B/F because there is not much hands we can extract value from. What worse hands could he call with? like 89, T8s, maybe he can have 99 but on the other hands he has better kings, aces + hopefully some draws.
So i think the thing you said in thread with my hand with the B/F question applies here:
if he has more worse hands than better ones that will call us, we B/F.
In this case 89, T8s,99 >> Ax, KT+, 77. We could add some hands (97s, 87s, K8s...) to his range but i think they are approx equally divided into the ones we beat and ones that beat us so it would not make much difference.

i don't like bet/folding on the river against unknown. your kicker is not that good and you have to pay off a raise on the river against unknown although its quite likely to be behind but i don't like my self being left with some uncertainty whether I've been bluffed off the hand or not. he might bluffbet a gutshot that he had chased down to the river. i like c/c as well.
