I am no pro but i think you betting 70 cents on the turn doesnt make much sense i mean what hands would you play like this for value you said it yourself you dont have any sets in your range also no two pair as you would not call a 3bet with K5 K8 85 pre also So when you bet 70 it almost screams you are bluffing and that you want him to fold. Since your KQ would not bet into an ace and you only have. The question is what aces you can represent and i dont think there is that many AQ maybe slowplayes AA but i dont think any other ace would bet that big even AQ you would fold in some cases on that flop so you really dont have that much value hands that make sense when going this big i would like you to go smaller since you are in position and by going smaller you can rep more strong hands in this spot. I dont know exactly how strong is 3 betting range is in this spot cause it depends on your game before against him how often you steal the blind etc. But him checking on the ace seems suspicious to me as he has a lot of those in his range. So honest checks would be KQ QQ JJ TT 99 but again he can have AA KK AK AQ Some AJ. Its very likely he has on of those hands with the Ace of diamonds so he is not scared of the flash. I would not really give him 55 88 unless you have a read on him 3 betting those hands pre cause i didint seem a lot of it in nl 2. I think a smaller bet than 70 wpuld get the job done in folding out 99-QQ maybs KQ but you are blocking those hands so he wont have them as often. But when he call the 70 i think his range is very strong and i would not fire again. As you wont really have a flash there almost never in a 3 bet pot when the ace and king are on the board and it was a backdoor so even less likely you got it. So when you bet like this you can only have AQ maybe? I dont really see you having any other hand for value And yeah. His most likely cards the he showed you would be AK AQ AJ with a Ace of diamonds imo. I do believe he could bluff catch you with hands like KQ cause your range really was not that strong

But he could also be trapping with AA KK or the AK- AJ cards without a diamond as your range seems so weak so he wants you to bluff by checking on the turn.

When he has AK AQ there or AA you wont have nothing most if the time as he blocks it hard so inducing blufffs makes a lot of sense even when you are in danger of the diamond flash draw

You should post your reasons for bluffing the river taking into account how much of your range doesn't get there and how wide you naturally want to value bet.

You should think about your defending range vs 3bets IP if you never have AK, KK or 88.

On the flop you say you don't have 55, 88 in your range, why don't you? Do you fold them pre to the 3bet?

You should never fold 55 or 88 pre, when you get rr in btn by small blind. You are way to far up in your range

FWIW, when you are trying to push someone off a hand like QQ-TT it is not advised to use QT to do it. 67s would be the ideal bluff hand here.

hman1992 when raising the BTN your opening x amount of hands, when you get 3 bet you have to fold call and 4B a % of that amount if you fold to many your will get exploited same for if you call too many hands so you have to balance your range accordingly,

what hands are too week to call
what hands are too week to call but i should 4B
what hands are good to call
what hands are strong enough to 4B

take your entire BTN open range and but it into one of them

Doug Polk would bluff this.

I think I would give up river with no real reasoning other than I think Ax is too much a part of his range and I think he is to likely too hero it.
