Hi guys, I'd like to discuss some marginal situations that I often face and I'm unsure how much impact making bad decisions in those situations lowers my winrate. I lack the analytical skills to find it out and I admit I'm also lazy to do so.

I get into these marginal situations usually because of emotions. In particular:
1. This hand is just too nice to fold here.
2. It would be just too "weaktight to fold here".

All scenarios are 100-130bb deep.

Situation one: coldcalling 3bets.

Typical scenario: 99-Jj and AQ at nl2/5/10. Tight reg raises from UTG/ Mp. Another reg 3bets him.
I have 99-JJ or AQ,what do I do?
Everyone tells me coldcalling a 3bet is stupid here because of getting sandwiched, in worst case even forced to fold to a 4bet.

So standard strategy would be either cold4bet/fold or just fold. I believe folding is the best option here. I will end up having to 4b/fold more often than taking down the pot by a cold4bet.

When we end up in a 3way 3bet pot I don't think I'm good enough postflop to profitably navigate im such situation when I don't hit a set. BUF it still "hurts" to give up on such pretty hands.
How much does coldcalling hurt my winrate there? 1-2Bb/100?

Hand type two: blind defend with offsuit brodways vs MP, CO and button raise. These hands are hit or miss. You miss 70% of the time. A large portion of the 3bet callers range is Ax, so even A high flops are not the best. Not to mention wet, coordinated boards, where the caller easily hits 2 pairs, sets and drass very often. And you play OOP.
Is coldcall the best option with these nonsuited broadways instead of 3bets? Or just simply fold?

Finally, 3betting from blinds with 88-Jj , AQ - obviously proditable, but what ro skfacing a 4bet. Just fold?

We are talking about tigt ABC regs.

TL, DR:
Coldcalling 3bets with nice but not monster hands ?(AQ, TT-JJ)

3betting OOP as blind def with trouble hands like KQo, KJo, QJo? Hard to play hands like 88-TT ( too many overcards)?

Better to just fold them instead of putting 10bb into a 3way pot. A way to a better winrate? Or coldcall. Which can still be troublesome, but c/c two streets with TPGK is decent play I think.

Cold calling can be good, but nowhere near at the frequency you’re talking about.

You can have dynamics where you have a whale open/calling 100%, and you know you can get the stack if your speculative hand holds up. More of a live thing.

Problem is that you’re so ungodly capped as a result of cold calling that anyone with a brain can print against you.

Basically would never do it. Cold 4bet or fold.

Don't do it.

SB or BB? Those are 2 very different positions.
From SB you are supposed to 3bet a linear range (only good hands), QJo is hardly ever there except maybe from time to time vs BTN.
From BB you are supposed to 3bet a polar range, with premiums and some "trash" like Q4s, 54s etc... Unsuited broadways are part of the "trash". When we 3bet the trash we really hope to see a fold, and when we are called I believe we expect to lose money on average. But if we never 3bet the trash our opponents will notice we have a very low 3bet% and we never get action with our premiums.[/QUOTE]

1: I recommend a 4b or fold strategy. By cold calling, you are often playing a 3-way pot and out of position. You aren't even guaranteed to see a flop. You will be dominated often and you won't get to realise your equity because of multiway and oop (often at least).

Much better strategy would be a very tight 4-bet only range. Against regs with decent 3-b stats, widening this range to incldue some bluffs with blockers can become lucrative, especially in position (eg. mp open, co 3-bet, hero 4-bet on btn). However, make sure you know the 3-bettor is not a nit and preferably a somewhat 3-bet happy reg. When you do open up your range, just choose the second best (non premium) hands like AQs, AJs, KQs.

2: When we are on BB facing an open and several calls, our pot odds get better but our equity, and more importantly, our ability to realise equity, becomes much worse. THis means that we need to tighten up, not loosen up. Think about folding the weakest offsuit broadways and think about squeezing the stronger ones. You can still call all suited connectors and small pairs.

3: You can assume tight 4-bet ranges from your pool. There is nothing wrong with folding the 88 and AQo especially as you are OOP. My advice would be to follow their 3-bet%: if they are 3-bet happy, they are also more likely to have 4-bet bluffs in their range. If your opponent has like 3% 3-bet, just fold all non premiums vs. a 4-bet. Of course you can also follow people's 4-bet stats, but usually those take a larger sample of hands to show anything significant.

Pairs are overrated generally. 99 or TT look like nice hands but when someone 3bets JJ-AA and AJ AQ AK KQs KJs etc then what do you beat? You're either dominated or facing 2 suited overcards. You will save money folding in that spot.
Calling offsuit broadways from bb, well thats poker. You need to make more than -1bb on average by calling pre. Not every spot is a "nice" one. If you are 3betting them and struggling then stop 3betting them or study more about when you are supposed to barrel postflop etc

What is this 2005 lol? Download some preflop charts from Zenith Poker/GTO Wizard/whatever and stick to them as a baseline.
Use a RNG for mixing.
