Question 1. 3bet preflop. What should I do?

If Vilain calls a lot of 3bet preflop, I should depolarise my 3bet range that is, I should not 3bet poor hands, but instead, 3bet medium-to-strong hands according to Vilain's open range.

Conversely, If Vilain doesnt call preflop 3bets much, I should polarised my range that is, I should 3bets poor hands and very strong hands.

Am I correct?

(other questions coming)

Yes

Question 2.

Generally speaking, Hero/Villain wants to bet/raise

1) with a polarised range when Villain/Hero is willing to fold a fair part of his range.

2) with a depolarised range when Villain/Hero is gonna pay with wide(r) range.

Correct?

Question 3.

Hero wants to cbet when... Mmmh... cbet, donk-bet, all the same as question 2. So this is all there is to (exploitative) poker. Now, I guess is the hard part: what is villain's range and intention with it.

Ok Ill try that.

Made a session micro-stake, decisions seemed a *lot* easier. Ive used a semi-aggro "polarised range" image against a table full of "depolarised" tight players (tailored for fishing). Ive checked strong hands against them post flop and they paid me a lot subsequently. Also made a successful 4bet preflop against the only "polarised" tight aggro. It was easy decisions and seems profitable.

If a guy has a polarised range, it doesnt make sense that he gonna want to call you down to hell and at the opposite, a depolarised range is tailored for calling down. So Im not sure Im telling the following the right way but it clearly seemed to me that you wanna use polarised against polarised and depolarised against depolarised. And you want them to think your range is of the opposite type.

...playing actually depolarised you've understood.

.... very often.

Mate, you wont get exploitative advice from the regular posters on this site, but let me help you out...

If the opponent calls a lot of your 3bets preflop, you dont necessarily need to bet more strength than GTO dictates. The only time the strength of your cards matter is at the end of the hand when the cards are turned over, and so, you need to consider how this hand will end before you can select your adjustment. The villain might well fold every flop unless he hits TP or better, and so against this kind of player we want to be filling our range with the 9Ts hands, low PP's, etc etc. When he misses his TP we bet and he folds. When he hits his TP we bet and then fold unless we have 2P, a set, some flush or straight.
As standard, if he calls the 3bets more often than GTO, we should add both bluffs and strength to our 3betting range, not just strength. To determine how many of each, we need to consider how the hand will end.

Conversely, if the villain is folding to lots of our 3bets, don't waste all your strong hands by 3betting them! Call them instead. You do want to 3bet lots of hands that we cannot play profitably postflop because this hand will end as soon as the villain make the inevitable fold, and so you do want to add weak hands to your 3betting range, but dont waste all your nuts.

In general, if the villain is folding often, we do want to bluff him often. But again, we dont want to waste all our nuts if he is just going to fold! We want to check our nuts often, make ourselves look weak, and then raise him on later streets and make it look like a bluff. I'm not saying you want to check all your nuts, but in general, you defo dont want to be betting with all of them when the opponent is bound to fold!

We do want to bet for value if the opponent is going to call. We bet our nuts, we bet all our strength. We want to make the most money we can off the weaker hands in his range. And if he is calling with all sorts of weaker hands, there is no reason to slow play our strength. But, if he is calling this street, we need to consider the next street before we can tell how many bluff we are going to need.

You seem to grasp Level Two exploitative Poker. To play at Level Two it is ALL about the opponents range. If you can put the opponent on an accurate range you will find it easy to rinse him. To do this you look to the past, you watch the game like a hawk, you watch to see whether he is playing certain spots with a polarised or depolarised range, and then once you have this information it's easy to choose the play to make with your cards. The best advice I can give you, to improve your Level Two game, is to consider the future. This game is not just about what we can do at any given moment to maximise our profits, in Poker, we aim to maximise our profits when the hand reaches conclusion.
