Is there anything I did wrong?

I think everything was played correctly until the river. Every time you commit money to a pot you need to seriously consider what you are trying to accomplish. By shoving on the river, what range of hands are you trying to get called by? I think the best case scenario is like pocket 10s or Js, but that only makes up a miniscule portion of his range. If he is calling flop and turn, you need to give him credit for more than TPTK for sure, especially on this board. I think QQ+ puts in a 3bet flop or turn so you are gonna be beat here alot of the time. If he has TPTK or overpair, he will check call the river so you have no reason to commit anymore to the pot. If he decides to raise the river, you will likely only the size of the pot at most. If he shoves or raises big river, you need to trust your read on this guys post flop aggression and preflop limping range. 76 definitely falls into that range.

Stats?

I'd be betting slightly smaller on each street so that you can bet/fold that river and bet an amount that would be called by a second best hand that makes sense for the sizing. Potting it on every street leaves you in a lot of odd river spots now, and shoving for 3 full pot streets is the sure proof way of getting felted w/ only one pair in your hand.

I'd only be potting it on each street with an overpair if I knew that villain was a big calling station. As played the river shove is not ideal as it allows villain to play perfectly (ie fold all his busted draws / one pair combo hands) and call with whatever is beating you. Even if he has 1010 or JJ it's asking a lot to get a call here.

This hand seems like a great example of over playing KK. The flop texture is definitely one where you want to be considering checking a good portion of the time, or bet flop (1/3 to 1/2 pot) and check call down to the river. You should be very worried when an opponent calls two pot sized bets, so the river should be a c/f. Sets, two pair and BOTH straight combos are in both opponents ranges pre-flop and are extremely conceivable in this situation.

This is exactly how I would play a set, but not an overpair. I'm likely only betting twice here.

By betting all three streets you are likely folding out a lot of the hands you are beating. As stated above, maybe 99, TT, possibly JJ stick around and pay you off. A8 folds turn to that size bet. 55, 98 all fold river. all sets and straights snap call river.

I think, maybe.

1) If you bet huge on the flop, there's no way to avoid getting it in.

2) If you get it in 150BBs on this flop 3 way and you're UTG, you're always going to lose.

3) This is a very clear flop check except against the most passive and loose opponents.

OOP multi-way on a wet board like this is a spot to check flop with everything.
You are suffering from range/nut disadvantage, and betting is very exploitable by floating or raising putting you in a tough spot OOP with a range that contains a lot of medium hands (yes KK is a medium hand here).
Good hands like KK should be played as a check-call, sets+ and best draws as a check-raise, air as check-fold.
If you do play this aggressively you should size down on all streets. Why bet so big? You are making it very hard for villain to call with worse and isolating yourself vs strong hands like in this case.

I believe villain will 3bet preflop with JJ+ and AKs. Since he did not and called both flop and turn pot sized bets he is representing a stronger hand than your KK. Limping with small PPs and suited connectors is totally within his range. Even with a hand like TP open-ended he will most likely give up on turn without improvement. After calling your turn pot size bet, he is representing two pair plus.

In this situation, without having any info on your opponent, I would err on side of caution and just check-fold river.

Without any stats on MP2 we are just guessing here.

Im not sure why some think its a auto 3bet with JJ+ and AK vrs a UTG open, how many do that at $10nl FR ?

Bet sizing seems off and i think id be check / calling the river here but its dependant on the size of the river bet

If this is vs a reg its terrible. If its vs a drooler its a little more acceptable either way though sizing is really bad.

I like check/call on this flop better. If they are loose then maybe betting is better. If I was to be it'd be betting much smaller though.

You can probably check/call one, maybe two, streets without improving before having to fold.

You have to laugh at everyone saying 'check this flop'. no reads on villain.

I would probably bet less on flop and turn. Check river and evaluate.

I'd say this hand was played out pretty bad.

1: Preflop is fine
2: On the flop I'd probably check, the range of button is really wide as of right now. If he has something like AQ, AJ, KQ, anything of that sort he is very likely going to take a stab at the pot. Furthermore, if he has an overpair (which you crush) he is also likely going to take a stab at the pot. There is no need for you to bet here as I'd assume most hands even if just 2 overcards are going to do this for you. You may scare away some trash with your bet
3: He calls, that means he likely has SOMETHING. Villain's range is not just broadway hands and a lot of people especially in position will call with suited connectors, they love it. 78, 89, J10 etc are all strongly in villain's range as of right now. Admittedly 76 is seriously pushing it but hey ho. 2 pair could easily be likely.
4: On the turn it bricks and you for some reason bet the whole pot (more or less). I don't really know why. Trashy hands that have missed are definitely gonna run, and likely only have 3 outs (if they have an ace), if any. Kings and also queens are worthless at this point. You do fold out 8 9 which is an open ended straight draw which is good, but I feel you can do this by simply betting half the pot and if they do call more often than not you'll get value from them anyway as their card likely won't hit. I can't see any hands that beat you comfortably i.e. 2 pairs and sets being afraid by this as there are no completed straights out on the board except for 9 10 and 54 (we can ignore 54 given you're UTG so it's just 910 which is in your range slightly but not enough combinations), so right now they are likely gonna bank on them being safe. The only reason I can think of to endorse this bet size is because it may get huge value from overpairs that are below yours, like JJ, however a: this is a small part of the range, these hands are likely 3 betting you on the flop, and and may fold anyway. But that is one reason. Beyond that I think it's simply too much.
5: Makes sense, at least it's consistent. If you're assuming your action on the turn is good may as well just follow through with a river bet. Hands that are better than yours are gonna bet 90-100% of the time anyway and I can't see you folding so may as well just fire to get value from the weaker ones. If they're not folding to a pot sized turn bet they shouldn't fold to a pot sized river bet given the blank. River play is fine considering.

Overall I don't think you took into account that there are genuinely a lot of hands that beat you, and furthermore bet too much and too loosely despite few weaker hands being likely to continue to that kind of pressure, meaning more often than not you're gonna end up with monsters beating you.
