PLO2 - Again somewhere I shouldn't be involved?

Max. call preflop if will be there only open rise, fold to 3B. You have no nutty single suited hand with 2 gaps vs multiway.
You can see you had luck on the flop but still you loose on the end.
(pot 0,96 USD = 48 bb, you have approx SPR2, after his rise you have less than 1 - you had to go in the pot)
If you had on the beggining no gap like KQJTds or AKQTds would be better for you in 3B pot.

Very easy fold.

Personally I am always never cold calling 3bets. Though some connected ds double pairs or best sort of rundowns are reasonable to do it though. But even then you should ask if cold 4betting is better option. There are just so many downsides in call that it's tough to beat those and also rake to show profit.

Plus easy fold in this one. Even double suited version I would fold as hand is disconnected and also these K high rundowns tend to suffer from proximity with AA and KK holdings. So basically hand like JT97 type would do better.

As a rule of thumb, never cold call 3bets. There are some very rare situations where it's +EV, but for starters just don't do it.

For call 3B I quess really some DS hand like AK+low pp, KK+low pp.
You are OOP and you can be squeezed by MP if he shove 4B.

Those who like to cold call 3bets, I would suggest to open a tracker and see the results on those cold called pots.

In short, we have 3 ways to gain edge (=to make money) over an opponent in a single hand.

Skill = our strategy and skills are better postflop
Hand = our hand/range is stronger
Position = we are in position

In normal 100bb 3bet pots (especially multiway, that cold calling often creates) SPR is so low, that postflop skill doesn't really matter. It's about who hits the flop. Our cold calling range is never stronger than the 3betting range (if it was, we probably should 4bet ourselves). And we are usually on the blinds, out of position.

That leads to a situation, where cold calling 3bets isn't a strategical advantage, but it's more about gambling and wishing for a good flop.

As said, there are some situations where we want to cold call 3bets, but as a default strategy my advice is a big NO-NO!

Ok, we´ll assume this your advice.
