Turn 3Bet Fundamentals - Heurisitic and Implementable Strategies

Turn 3Bet Fundamentals - Heurisitic and Implementable Strategies

Hello to everyone,

I am pretty lost with how to bet and play on the Turn in 3Bet Pots.

The solver bets massive on some broadway cards, checks some broadway cards, overbets some bricks, checks som bricks, on GTO Wizard as the aggressor and I cannot work out why or what it is doing.

Does anybody have simple easy content which can best explain the theory of 3bet Turn play?

If you're not utilizing block sizings OOP in 3bp, then generally speaking the ranges for betting will be roughly polarized and trend towards a geometric sizing (~100bb eff).

I am using GTO wizard and I find it checks a lot of bricks on the turn when I thought OOP 3Bettor would be betting bigger and more frequent but GTO Wizard wants to check.

Do you have any good source material to study Turn on 3Bet Pots?

Thanks for your last reply.

In any nodes where the OOP 3bettor is primarily utilizing a small sizing with a high frequency on the flop, then turns will check pretty often and again primarily shift towards a geometric sizing and a polarized strategy if a small bet is not allowed again on the turn. Any equity shifting turns such as when a flush completes or when a lot of straights are possible--the OOP player will usually check at a much higher frequency compared to a blank card.

No.

Without knowing the specific PF action, effective stacks or the board cards, it's difficult to give specific advice, but unless you're opponent is a fish, he's going to have a pretty strong range after calling on the flop, especially if the board cards favor his range.

In a nutshell, you really don't want to be blasting the turn for fold equity unless you're deep and his range his capped.

Good summary.

@op

When you bet near range on flop and villain calls, you show up to the turn with your entire 3b range including all air, while opponent has folded a lot of their trash hands. So while you do usually still have some advantage cause of hands like QQ KK AA AK, after those hands you usually aren't doing super amazing.

So, it's natural that you have to check a lot.

Like Brokensrars said, typically when ranges are like this you use geometric size as it's the best way in theory for your value to get money in. So, you usually play lowish frequency geometric size on bricks.

On more wet/connected cards, typically your betsize will shrink and you also can't go crazy with how often you bet
