EP opens 5x MP 3bets 300bb deep:

Christian soto mentions in his most recent LATB video (the 20k pot);

'With this stack depth (300bb deep) HJ can 3bet a merged range for a small sizing (around 2.5x) and 65s can fall into that category, If I was him I would 3bet A2-A5s 65s-78s and a plethora of suited broadways like JTs-AQs AKo. '

soto calls this a merged 3bet but he didn’t include 89s-9Ts 22-TT. I am curious about this because I lost a big pot in these positions when HJ 3bet my EP open with 9Thh and I thought he would never have this hand, he seemed like he was a good players so I don’t know if he made a mistake or this is a legitimate strategy.

He could of just been randomly clicking buttons. I doubt most players at this level have a set range they 3-bet with. I don't.

When you’re really deep and you 3bet say AA and the board is really crappy, say 567 - the thought might occur to you, “my range here is mostly JJ+, AQ+, and this villain could really exploit me knowing that I never have very strong hands”.... It’s this thought that will make you want to start adding hands like 56s or 89s into your range. On the flip side, suited connectors can play really well as flats compelling us to not 3bet them. But 56s gains more from additional preflop FE than 89s (as 89s will tend to have more hot cold equity), so you may want to 3bet that more than 89s.

Regardless, none of this is set in stone - the point is make sure you have some very strong hands on various board textures in addition to overpairs, but also try to be somewhat polarized (raising the lower and upper parts of your range), and don’t overdo it because if you 3bet too much, that’s going to get exploited in various ways.

Yeah definitely don't overdo it; you want at least 60% of your 3betting range to be high cards and high pairs. But do include a few suited Aces and suited connectors in your range. Potentially some low pairs and suited gappers too. But try not to put hands like ATs and 88 in your 3betting range, as these hands have SDV and are better played as flats.

hell yeah im 3betting 9Ts IP. I dont even have to be deep to do this, although the 5x open raise kinda hinders it.

I'm much less likely to 3b if fish are in the blinds, and more likely if good players are in the blinds.

It should be situational and opponent dependent. Im less likely to do it against an EP raise than an LP raise because the EP range is much stronger and you get called and 4bet much more often. Against an EP raise Im more likely to just call and try to stack an overpair.

You want your opponent to have a wide range and a fold button if you ate going to 3bet polarized. Otherwise just stick to value hands.

I think OP is asking about deep stacks, where presumably people don't stack off with overpairs as easily. He wants to 3b lighter and take advantage of players having to play tighter. 300BB deep I don't think many players are thrilled 4betting anything besides AA and KK (very narrow part of a standard 88+, AJs+ range), so the likelihood of that goes down too. We get to play perfect vs the 4b if the villain isn't 4betting non-premiums.

Me too but situational and V dependent.

The guiding principle behind these statements, which is what you seem to be asking about, is that you don't 3bet when a hand is worth more as a call. So if a hand is being left out of that range it's because he'd rather call with it than 3bet.

Maybe the problem is that he's using the term "merged". A merged range would include basically everything. The range he's laying out is still technically polarized, albeit much larger than your typical polarized range.

This

Does Christian mention the early villain's 5x range at all, and whether he's folding an over pair to pressure or stacking off with it? If not, he's just clicking buttons. Every villain and situation is different, it's not based solely on being 300 big blinds deep.

I know the only spot that I would 3bet 9Ts is if a bad lag opened and I was in position and the blinds were competent and I wanted to 'iso' him, other than that at 100bb poker and above I would never 3bet this hand because its a profitable call, if I wanted suited connectors I can go for the 1 and 2 gappers. I am sure the solver would 3bet a small frequency because of board coverage but there is no real need for that in most games when you are only playing a few thousand hands against people that don't take any notice anyway.

The 5x open made by the UTG was Christian himself (you can open large in live games because everyone is deep and terrible), I am very familiar with 3betting merged ranges IP deep and do it all the time but they aren't this merged, I usually go any suited broadway any suited ace, no-one folds live deep so theres not much point in 3 betting wider, I can see the case for 3betting suited connectors online because people fold more.

The only times 99 is in my 3Bet range is when I’m in the blinds and RFI is coming from the button or cutoff.

With 99 versus RFI, is call or fold for me, with a weighted towards call in aggregate but will lean towards a fold in LJ and before and lean toward call after.

Yeah, when I first started out in NL was really used to the small caps and didn't really understand the old timer who told me you aren't really playing NL if you cant call the 4 bet in position. I kind of get it now, even though the opportunities don't really come up that much in the current cap structure.
