3! preflop for one thing.

Very strange hand. Like deuce said definitely 3! pre. Then probably just bet 1/3 on flop, 1/2 on turn & something smallish on river. Over shoving for 2x pot on river seems horrible. You are never getting called by worse & you are making it easy for V to play perfect vs you. On the other hand if we bet something smallish we might get called light or V might decide to get creative and check raise. The way to get value is to create a bigger pot pre & play less face up post.

Agree about the river sizing, particularly since your hand is not all that strong on the double paired board, although the mid position raiser probably doesn't have a 3 or 5.

You should almost never flat call with a big pair from late position or the SB. From ep, it is possible, as a 3! looks strong and someone may squeeze. Here you are on the button, so a 3! could look like you are making a play with position and there are not many players to act and squeeze. In general, you are OK never flat calling preflop with QQ+ and you should balance with some light 3!s.

Always 3b pre in small stakes. Before flop AA is big favourite, and in theory flatting should be done sometimes but compared to theory following things happen in small stakes:

a) It is less likely that SB or BB will 3-bet squeeze many hands they are not playing against 3 bet.
b) It is less likely opener folds too much, or even enough against 3 bet
c) more likely one of the blinds cold calls 3 bet with insufficient hand

By 3 betting AA here you get to play big pot in position, with hand that can almost always bet 3 barrels postflop in order to get all in.

As played your hand is still extremely good after flop so you can reraise there with the intention of barreling all in. Your opponent is likely to call with QQ-KK and some Jx.
As played you can bet turn bigger, 10-12bb in order to make river push less than pot. Additionally you would price out turned flushdraws.

As played river push is around 1.25 pot effective and its not that hard to change sizings in order to keep it under pot sized push. I would prefer going for stacks in this spot given opponents position and the relatively high amount of Jx-KK compared to 5x or 3x hands.

I don't know what's the buy-in here, but in the games I play, they can call with many worse hands than that
Villain dependent, but still...

So yeah, you need to value as soon as you can (pre and flop), this is where villains make the biggest mistakes.

Yeh, at low stakes, probably just always 3! and generally cbet AA and usually JJ+/AK. People are not folding much to the 3!, so that is the easiest way to get value.

At low stakes you generally should just go for value and not get fancy. If you flat call AA, it is unlikely someone will squeeze. Some people don't 3! much, and may only 3! JJ+/AK or KK+ or whatever. So you should almost always 3! big hands. Unless the action is really wild, 3!ing light is also a good idea.

Perhaps OP never 3!s anything, including AA. If so, that is a major leak.

Hey I usually 3bet wide since I think people in low stake MTTS on ACR actually overfold. That is why I flat my AA. I have actually found that I get more value playing them like this preflop because villian basically is incapable of putting you on AA when they are this weak
