Interesting hand , overbet river

This hand is a gem

1st. 3bet him preflop. I could understand if you flat AK in position vs UTG open, however, flatting this one from the SB is losing you money. Just 3bet him to 10 bb and go from there.

As played on the Flop - i guess its fine to check raise the flop. Sometimes he will have weaker King, sometimes he will not believe and will call with Tx or random pair. I guess he always calls AJ/AQ/QJ.

Turn - Why exactly do you check? Why? Oh god your play tilts me. The only hands you are behind are TT and KT... ok and 77 which falls in the above "random pair that calls your flop raise". Bet man, just bet big. Make him pay. He has all KQ/KJ/AJ/AQ/JJ/QQ/Tx type of hands that would call a bet. After your check - why are you not raising ?! Why do you check/call ? Please share your though process so we can evaluate your hand in the best possible way. May be you have some info on the player that we are not aware of?

River: I guess its ok to fold it. He would check behind all hands with showdown value like Tx/JJ/QQ and the population would not bluff this board, like ever. This is a push for value. He has a lot of combos with the diamonds, especially when you do not hold a diamond. He has many T♦:x:diamond: that he continues the flop with as well. You beat his KQ and KJ though and split with AK.

Assign him with a river range of 9♦:T♦:/ A♦:J♦:/A♦:Q♦:/A♦:T♦:/Q♦:J♦:/T♦:J♦:/T♦:Q♦: KQ KJ TT and AK and calculate your equty.

Edit: I refuse to see the spolier so i didnt

Preflop definitely 3b, I don´t see any merit in calling AKo in this spot. OTF I think x/r is fine given we have AK in our range. OTT why don´t we continue going for value? OTR really stupid, unusual situation, but I believe it´s a snap fold. Paired boards don´t get bluffed often enough + FD got there + overbet is gonna be very valueheavy. What bothers me is that we capped our range OTT and he might attack that, but on the other hand I don´t expect ppl to do that on NL5, so just fold.

3bet pre-flop. You'll be OOP for the rest of the hand and you can't represent a lot from that position.
His cbet is standard on a paired flop after your check.

What do you check-raise him for? He'll fold a lot of the hands on such a dry board. I doubt his continuing here without a K or a T. Even a OESD (QJ) is likely to fold.
By check-raising you're giving away to much information about your hand and cutting the value you may get from him on later streets.
I'll just call his cbet.

Turn and river is just trying to get all of his stack in the middle. He called your check-raise, so just continue betting OTT and OTR.
You can't be afraid of the flush because it doesn't match the flop action.

To be clear I didnt bet turn because i wanted to represent hands like Tx, so I wanted to mask my Kx hand. Overbet river is something i didnt expect.

very bad line that makes no sense for the most part

you either c/r flop to 3barrel him, or you play it passively. I would only consider taking this c/r F c/c T line at higher levels of play, to balance my c/r Flop c/c Turn range (which could be ok with weaker KX hands).

As played, hand is underrepped so easy calldown.
