[MICRO] Ok, now I folded with overpair, was this correct?

Opponent had pretty standart reg stats.

Way too tight in my opinion.

Villain could have pair queens in raising range on flop and loads of drawing bluffs which miss turn.

Looking at the GTO it says it should be a call or ALLIN.

Stop including results dude. And start including your thought process. What hands do you think he has and plays this way? If you dont know, think as if you played this hand.

So, sb doesnt usually have a flatting range vs button. I think he might have 99 or 55 here, although 99 should be 3bet and 5 are less likely as there are two on the board. Definitely no QQ. Could have Q9 if he plays that, maybe even Q5; dont think he should have 95 (well, he shouldnt have anything, but those would be even wider than what i think it could be). There is also Qx that you beat, and a whole lot of flush and straight draws - Kdxd, JT, 87, 76, J8 etc.

You could think about 3betting on the flop and getting called by Qx or draws. As played, when we see a second 5 i think its even less likely villain has a good made hand. I think i would call on this turn and see if the draws complete and if he keeps blasting and go from there.

This is NL2, he could have QQ and not tribet, or even Q5o. Althought now I see its way more likely he has AQ, KQ or KK than those hands. My thought process was "sometimes we have to fold overpair and opponent tribeting flop and keeping the agression on the turn may be one of those situations", I was wrong tho, I was too shook by some previous hands where the opponent hitted a monster vs my top pair.

I play NL2 too. I would say 95%+ of opponents know to 3b QQ OOP. We can't be afraid of monsters under the bed - he should 3b it, and if he doesnt, he will lose more in the long run than if you pay him off this time. If that happens, take note and know that you're against that kind of player and take his money in the future.

The long answer is no.

GTO assumes your opponent is balanced. Which means that they will have many bluffs and semibluffs here.
This is not the case at nl2.

"although 99 should be 3bet preflop"
If I have a calling range in SB, 99 would be it. The only combos I call from SB is 77-JJ and with nothing else.
"Stop including results dude"
That only applies to hands which went to showdown or to actions that happened AFTER hero's last action.
"You could think about 3betting on the flop and getting called by Qx or draws"
Terrible idea.

OP:
he may have standard reg stats, but the fact he called from SB suggests he isn't too good. It is plausible he called with 5x, 99 preflop.
The fact you have the ace of diamonds here makes it less likely he has a flushdraw here as suited Adxd combos are not in his range which makes his range even stronger. What you have here is a bluffcatcher.
So I think the fold is good. In general I believe it is better to overfold in the micros against raise then big bet on the turn line. In fact, folding big but not big enough hands is the second most important part of making (saving) money at the micros righ behind value betting properly.

Finally, does he do this with KQ and AQ? Some villains do, but looking at the general population, you won't see those hands frequently enough here to justify calling just to see the river where you will likely face a jam.

Honestly we are not loving it because many microstakes players have next to 0 bluff when they CR the flop. But folding on the flop is not an option with such a strong hand, we even have Ad for the backdoor nut flush draw.
When the 5 hits the turn it reduces the number of sets in villain range and now we beat Q9. Check/raising a 5 on the flop is a thing in theory, but again, not something I expect to see very often at those stakes.
Call turn.

TLDR; c

Folding isn't the worst really to remove high variance spots which you don't need to deal with at 2nl.. but I do think you really should call the turn for the price. Ad isn't great but still enough value that we beat like QJd,KQd.. Q9 bit less likely but some fish dont care about the board pairing on turn.

Way too tight of a fold imo. I get it if the turn is an 8 or something, completing a bunch of draws and so on. However the 5 turn is really good for you as it now reduces his value combos - much less likely for him to have 55 and you now beat Q9 that he can still be betting for value.

It is true that "overpairs don't want to get the stack in (at high SPRs at least) when opponents show a lot of strength. However you need to interpret runouts. The first thing you should ask yourself when facing a bet is "What's his worst value hand here". Well, it can be Q9 (which we beat). How many better combos than that are there? Well... he has 1 combo of 55 and maybe 1 combo of 99 (some will 3b preflop). Maybe some weird trips that he decided to xr flop. And how many draws? Well.... loads. JT, KT, 67, 78 and all the flushdraws. So you beat some value, he has a really low amount of combos that beat you, and a lot of bluffs available. Don't wanna be mean or anything but for these reasons this is a terrible fold.
