I can't see the value... A or K or Q high flops every villain just folds and here every time something like this happens. Only profitable against nits. Am I leveling myself or what?

Are you asking why you should 3-bet AK? Or why you should c-bet this flop? Or why you should check this turn?

Lets leave preflop as it is. Is this good way to play flop and turn? Because I'm starting to doubt it...

Preflop I raise bigger.

Since he is unknown I give him credit for a pair here most of the time and note it down that he is likely calling 3bets wide if he connects with this board, or that he is trying to play tricky. Either way I adjust my 3bet % and let him value town himself when we do hit, the way he donks turn shows you how easy it will be to stack him when you have it, you could just as easily have JJ+ here and he would never know

Also with pf raise sizing i bet like 160 flop but idk

shifty

Preflop is fine @ 120 (why make it 160?)

Shift - you are giving some guy a note because he called 3bets wide when you didn't even see his hand...

Does this seem weird to anybody else?

All the cards on the board are low. Unless he had overpair or he is a total fish, he had 2 low cards.

"Why it's correct to play AK like this OOP against unknown?"

Well, preflop is an easy 3bet for value, u put money in the pot with a hand that dominates his calling range and plays quite well postflop, u dont need any explaining there do you.

This is a good flop to cbet, since its semi-dry (so u have very decent fold equity) + u have two overs when called, so a lot of good turn cards (either those who improve your hand or those you can barrel profitably).

Once you get called, that turn card only improves his perceived range, so hes not folding much that he called the flop with + our equity dropped significally, so its an easy c/f (at these limits especially).

Now, i dont know why you think that this line isnt profitable, you made the most ev+ decision on every street. Maybe its because you arent barreling enough good turn cards, so you feel like you always lose when you dont hit a pair. In that case, you should work on recognizing which spots are good for a double barrel and which arent and then you shouldnt have any dilemma why it is profitable to play AK oop this way.

Just think about it:

1) opponent folds pre
2) you hit a pair or better and get a lot of value from his dominated hands, since the pot is already quite big
3) you cbet w/o a pair and he folds
4) you cbet w/o a pair and he calls and you spike on the turn
5) you cbet w/o a pair and he calls and you barrel a good turn card and he folds

So many ways to win and so much value in playing AK like this, its ridicilous.

umm there are combos of 10x that are standard defend hands against a 3 bet. He could also be floating the flop with different types of equity

Why not make it bigger?
w QQ+ i like this size,but AK we have the best hand most of the time pre,when A or K hit the flop good % of his range will fold to cbet so we want to charge more pre and if he have Kx Ax the pot is bigger.

Why bet the flop if you don't intend to second barrel the turn? This doesn't exactly hit your 3betting range very much.

I check behind on this flop, sure it's dry but a lot of calling ranges has this hit more than you. I think c/c is ok and if you feel the need to bet the flop, I bet slightly more and lead out the turn and fold to shove.

actually checking is fine vs fish that will call u a ton and fold to a bet, i know its exploitable but fishes aren't really gonna exploit u and its the most ev+ line, u have showdown value and ure keeping the pot small.. i like raising bigger pre if u dont balance ure reraising range vs fish, so u can read his range better, something like 150 is gonna make u have some fold equity, if he knows u bet and give up the turn when u have air he can float wide flop and steal turns or fold double barrels so basically in 3bp when u check the turn u have air and when u follow up u have something.. pretty solid read in 3b pots

You can't check behind, we're oop. And 'c/c the is ok if you feel the need to bet the flop'? How is check/calling betting out the flop? If you meant c/c the turn, I think you should rethink your strategy.
