Again another post where I'm trying to find out why we do stuff. I think about 3beting a lot as it's something I encounter a ton and I'm trying to figure out how to beat it.

So I'll divide it into hand categories and see why people 3bet certain hands and if my reasoning as to why is correct.

Premium pairs: QQ+
I thought about these hands and the only justifiable reasoning I could come up with as too why it is a smart idea too 3bet these hands is too isolate, playing big pairs multi-way is stress. Because let's think about it, say we are in the BB, and everyone folds to SB, who makes it 4bb to go. He's a TAG and folds too 3bets 90%~ of the time. Ignoring the BvB dynamic and the fact that people constantly level themselves and stack off way too light there, why should we ever 3bet in this spot? Isn't calling going to net us more money long run than 3beting? Even if it is just so we snap off a cbet.

AK:
This hand has always troubled me. A ton of people consider it the nuts and I think that's because it's a flip with QQ w/e. If I was to ask myself how big of a pot I would want to play every time I look down at a starting hand with AA I would think "for stacks unless given a reason not too" with 22 I'd think "probably a small pot unless I hit a monster" and with AK I'd think "probably a medium pot unless I hit a monster". So again why do we 3bet this hand? And again all I can think of is too isolate, this is definitely not a hand we want to play multi-way (and at uNL multi-way is common). By 3 betting this hand HU what do we achieve except folding out the hands we have in bad shape AJ KQ KJ etc?

SC's and small PP's: 56s-9Ts 22-55 or w/e aka 3betting light
These are the hands that too me actually make most sense. 3 betting with these is never to isolate unless we are picking on a specific villain because we understand how they play and are able to exploit it, as these hands benefit multi-way, and really require more implied odds than generally exist to CC profitably. Technically it's a bluff that when called are easy to play.

88-JJ:
These I'm lost with, these are hands that are hard to play in 3bet pots, but also hard to play multi-way. HU I can see little reason too 3betting them, and multi-way it's a coin toss as I see benefits for both arguments.

how about taking initiative (thats a common thing you should be thinking about ) in hand.. i think its one of the most important "whys"... second thing we want bigger pots when we have premium hands.... i guess its betting for value ... anyway we 3bet to get more money from opponent in pot perflop... and we want to isolate people because its lot more easier to play a HU pot... all these good hands really aint that good all of a sudden if we are in 3way 4way pot....

permium pairs are ****ed when A high flops comes.... so there is no need for us to just call with those and let all those weak aces hit their hand... and the more we let other to see cheap flops againt our big hands the bigger the chances they ll hit big on us... they still will hit time to time.. but we charge them for every time they miss or make a second best hand.... well in BB its a differant story you might sometimes just call there... its not like you always have to reraise with AA... and AA is safe againt A high flops... so you can call there and play tricky time to time...depends on your opponent....

AK .. we all know its a strong raising hand weak calling hand.... so we raise it... same reasons ... we 3bet we can take pot right there right now.... if he calls great... we can flop a big hand.... if i dont... no biggie we can take pot with c-bet... he calls we can still hit an A or K against big pairs who are worried about overpair (this might not be a standart thinking..i dunno really its just my opinion) so yeah.... why not to raise? of course we can again sometimes play tricky depending on situation to win a big pot against KQ AQ when K or A hits...

SCs and small pps... well here we wanna mix up our play and not be so predicitable in our 3betting range... throw these in time to time because most of the time nobody will think we have any of these hands... same patter.. we can win a pot preflop ... which is a good thing... a lot of people raising with so bad hands that they just dont wanna call with them a 3bet... which is not bad for use... we just take that free money...

88-JJ is tough to play... we basicly 3bet to isolate thats a priority i think... still pairs are best hand pre flop a lot of times... so you should be raising them for value.. its just tougher to play them because of overcards... but that doesn mean you have to fold TT every time there is a Q on flop.... calling is not a bad play with these either... if you flop a good flop with hands like JJ TT 99 you can win a lot from smaller pairs... i agree that 88 - JJ is somewhat toughest to play.... still like i said most of the time its best hand preflop...

so anyway.... thats how i see these things from what i have red and learned... feel free to correct or add anything i missed....

i find 3 betting out of the blinds with aj+ is profitable because depending on the player they will call u with easily a weaker hand and u just gave easy value from this play

IDK if it was mentioned, but denying set odds to smaller pocket pairs is a huge part of it. I prefer to 3bet pairs only vs. very aggressive opponents and will usually just flat TT and JJ.

For the most part I 3-bet premium pairs for value. Unless I have good reads on a villain, I usually call anything else such as pp's, sc's and some non-AK broadways.

I think 3-betting to take the initiative is wasting a TON of value.

Well maybe it's easy for you but I have a pretty damn hard time playing guessing games out of position, which is what I'm always doing when I flat from the blinds. I feel like I spend about half my time folding the best hand and the other half calling with the worst.
