villain is fairly uknown but he has 3bet like 8-9 times in 30 hands so i decided calling with KJ IP is ok . This is standard right ? i check the turn because if he had an ace he would barrel most of the time and i give him a chance to bluff the river or make a crying call with something like TT when i valuebet the river.

so if you played 30 hands, he was on the BB and had a chance to 3bet only 15 times. He 3bet you 9 out of 15 opportunities?

yes.

this just makes no sense. he can't barrel because he already checked, DUCY? you should bet the turn.

he not bluffing much on this kinda board with this kinda action. betting the turn >> bluffcatching on the river.

no he 3bet me about 9 out of 30 opportunites, i didn t express it right. so we played like 60 hands but not a lot of action postflop since he was folding to all my 3bets and i was folding to his.

It does make sense. He cbet OOP but he didn't follow through on the turn . If he has an ace he is betting the turn for value most of the time. I checked because i can't find worse hands that he could have (except maybe a weak A which he doesn't seem he would 3bet) that would call. so i prefer to underep my hand and valuebet a river that is not a Q.

All in all i am definitely not saying that betting turn is bad , it's definitely good , i am just explaining my thought process and why i thought my line was more +ev at the time.

I agree with betting the turn. He can definitely have weak aces if he's 3betting ~30%, he can also call w/Kx or a turned diamond draw. Basically there's some value and people rarely take bet check bet as a bluff line as it's not too credible. The river looks good though, you're getting about 6-1 there's no folding 2pair with those odds.

in short, you have a vulnerable hand (what do you do if a T, Q, or A hits on the river?) and you can get value from worse if you bet the turn.

def bet turn, poss fold if shoved on. as played call river. he could easily be min raise bluffing if he is putting you on a bluff and doesnt have the hand to just call.
