KK easy fold after flop x/r. But flop bet (size) was a mistake?

3bets ok i usually do 3x ip and 4x oop and add on for any callers in this case 4x4+4=20bb. Postflop you could go smaller something between 1/4p to 1/3p so around 10bb to 12bb on such a dry A high board given your the aggressor in a 3bet pot on that flop. I wouldn't think 15bb is a big mistake or anything i just think the sizing is likely a tad to big here. Otherwise it looks ok i cant see worse raising on this flop given it hits your 3bet range. This is full ring though so it likely changes things slightly from what i play which is 6 max.

I'd check back flop here, your equity is robust, you can only get value from bluffs, and you will probably not be able to get any better hand to fold. Or let's put it that way, you need to bluff sometimes, and you can better use low SD value hands with backdoor equity.

Hi!

I am not used facing 4bb opens pre and FR ranges but imo your sizing is okay preflop.

This is the best sample of flops what you can range cbet for sure. If you do so it is fine to cbet sg between 5-10bb.

On the other hand if you want to build a check behind range this sould be your 1st candidate for that besides some weak Ax suited hands (if you had those bluffs pre).

The reason for it is you are way ahead or way behind. If he had Ax u r pretty much fckd but if he had high cards or pps you don't need protection and can't get value on multiple streets anyway.

PF is fine

F: Could go either way
Cbet most of your range 1/4-1/3 pot bet OR Check back Flop. Betting 1/2 pot or more would be a terrible choice with your range and with your specific hand.

It really depends on what strategy you would like to use.

a) vs a brain-dead fish whose default thinking is "he checks the flop, he doesn't have anything so I should bluff"
check Flop and snap his turn + river bets
b) vs a thinking guy who thinks "this is a nice board to bluff, if he doesn't bet he has weak AX or KK-JJ"
his counter is to start blasting you off on Turn and overbet River OR to immediately give up and never make any moves.

You either check some air combos to delay bluff the Turn (to let him reveal his true hand strength on the Turn - he leads with AJ/AQ and checks most of his air OR you might get 88-TT to fold to a delayed bet that would otherwise have called once on the Flop if he thinks you would delay cbet only AX/KK-JJ and never air) WHILE checking back some AX hands that can snap Turn + River

OR you can use a simplified strategy of betting whole range with 30% pot size bet and then playing Turn (probably folding vs River probe bets unless you think he's capable of floating OOP with a hand like QcKc and bluffing River)

Preflop: I would not expect from him AA, QQ he would 4B this hand vs BB. You are blocking KK. When UTG call 3B I would expect hands like AK, TT-JJ more AK hands.
F: After flop bring A he has 95% Eq with AK vs 4 % for your KK. You have to call 15bb to pot 81bb - cca 15%.
If he rerising with + TT, JJ to bluf you, you have 62% Eq - 15bb is low price.

Preflop is fine. It's a small sample size but given stats I'd guess UTG has a pretty tight range like AQs and 99-JJ. Maybe some more pairs, maybe some more AJs or AK types of hands. I'd also assume you have a pretty tight range here yourself.

Flop as others have mentioned there's two ways to play. Cbet your whole range small or have a check behind range. You don't likely have a lot of draws in your range so splitting your range gets tough. Villain is also pretty polarized between 1) hands that beat you and likely aren't folding and 2) hand that you beat but probably aren't calling more than one street. I think I'd tend toward checking behind here.

Once you are raised I wouldn't ever give a 14/8 credit for bluffing here without a read so easy fold imo. I don't see players turning TT into a bluff here and he doesn't have a lot of worse combos to put into a bluffing range.
