3 Concepts That Should Shape Your Postflop Strategy
Are you familiar with positional, range, and nut advantages in poker?
These concepts will help you shape your postflop strategy to make more money in good spots and lose less in bad ones.
In this article, you will learn about each of these concepts and how exactly they should impact your strategy. Let’s start with what you probably already know:
What is Positional Advantage?
Positional advantage refers to the strategic advantage of acting last on each street.
Why is positional advantage important?
Information is power (and profit) in poker. Acting last on a street is advantageous because it gives you more information when making decisions. More specifically, he will have a clearer picture of his opponent’s range. This will in turn will allow him to create more accurate, higher expected value (EV) strategies.
Using your positional advantage correctly will allow you to bluff-catch, value bet, and bluff more effectively.
What is Range Advantage?
A player is said to have the range advantage if he has the largest share of the equity in the pot.
Why is range advantage important?
Range advantage is a cornerstone concept in poker theory. It dictates the general shape of the strategy a player should employ. All else being equal, the greater a player’s range advantage, the more aggressive his strategy should be.
That is because, fundamentally, he has more high equity hands than his opponent. The higher your equity is, the more incentivized you are to increase the size of the pot, as you are the favorite to win it.
Let’s say I raise on the Button and you call in the Big Blind. I start with a range advantage because my preflop range is stronger than yours, and this range advantage almost always carries over to the flop.
My Button raising range will have around 54% equity against your Big Blind calling range before the flop in this spot. Here are the ranges I estimated for each of us:
- Red = Raise
- Green = Call
- Blue = Not in Range
On some boards, my range advantage will increase, such as:
- Ac Kd Qs >56%
- Qh Jc Td >56%
- Kd Qs Tc >56%
- Kc Jd 4h >55%
- Qh Tc 3d >55%
On other boards, your range will pick up some equity, though it will rarely be enough to take the lead. The reason for that stems from two forces that act against you: playing without positional advantage and having a nut disadvantage (or only a small nut advantage). Here are a few such boards:
- 9c 7s 5h <54%
- 7d 5s 5h <54%
- 8s 7d 6c <54%
- 7h 6c 4d <52%
- 6s 4s 3d <51%
The pattern is pretty clear: Higher boards favor the Button’s range while lower boards favor the Big Blind’s range.
Pop quiz: Whose range would gain equity if the flop came Js 3d 2d? My range on the Button or your range in the Big Blind?
Your range in the Big Blind.
Going into the flop, you had 45.33% equity. Once the flop falls Js 3d 2d, your equity increases to 46.49%.
This 1.16 percentage point difference is not enough to give you a range advantage (that still belongs to me on the Button) but it is a relatively good flop for you in terms of equity.
Significant range advantages are also common when the Small Blind or Big Blind 3-bets and the initial raiser calls. In those situations, the 3-bettor will usually be right to use an aggressive, high-frequency c-betting strategy.
The preflop aggressor doesn’t always have the range advantage though.
When a player raises preflop and gets cold-called by a player that has position on him, the cold-caller will usually have the range advantage. This is because the cold-caller’s range should be pretty tight and strong given that he called with players behind him that can squeeze him out of the pot.
The preflop raiser will have more super strong hands (JJ+, AK), but these will often be outweighed by the many missed hands in his range.
What is Nut Advantage?
A player has a nut advantage when he has more combinations of very high equity hands (85%+) (usually two-pair or better) than his opponent.
Why is nut advantage important?
Nut advantage matters because it strongly influences how often and how large a player can bet or raise. The player with a nut advantage should usually use larger sizes in order to try to stack his opponent when value betting, and to apply maximum pressure when bluffing.
Let’s say you raise on the Button and I call in the Big Blind. The flop is dealt As Kd 5s.
In this situation, you have every combination of AK, KK, and AA, while I have none. So, you should bet very large to give yourself the best chance to stack me by the river. My hands are tied as a result; I can either call you down with a sensible range or over-fold, which allows you to bluff me super-profitably. In other words, I have to choose between getting stacked often or getting bluffed often.
The preflop aggressor doesn’t always have a nut advantage. If the board was low and connected in the example above, the Big Blind will often have a small nut advantage. Unsurprisingly, these are the same boards that favored the Big Blind in the range advantage section:
- 9c 7s 5h
- 7d 5s 5h
- 8s 7d 6c
- 7h 6c 4d
- 6s 4s 3d
There is overlap because nut advantage influences range advantage. When your range has more nutted hands with 85%+ equity, your total equity is increased because of those outliers.
On these low, connected boards, the Button should use a less aggressive c-betting strategy. Otherwise, he runs the risk of getting exploited by frequent check-raises from the Big Blind, who will often have a strong hand.
When both players have close to the same number of nut combinations, neither player’s strategy should be altered.
Note: At lower stakes, due to much higher rake, the Big Blind is forced to defend with fewer off-suit combinations. This means that, unless the Button opened for a min-raise, the Big Blind will not have such a big nut advantage on those low boards. (All of this assumes that the player in the Big Blind is attempting to play a solid strategy preflop.)
Conclusion
These concepts are at the root of all poker decisions. Be sure to take them into account and build your strategies accordingly.
