Preflop Opening Ranges
14 Apr, 2011
This is a guest post by Kyle "SHIPIT2KG" Garner. He was a coach at Jack Wilcox's old HigherLevelPoker.com training site. I decided to transfer Jack's articles to this website in August 2020, and thought I'd include the articles by other coaches whilst I was at it.
In NLHE there are 1,326 different starting hands.
That's a lot of hands, and we must arrange these hands in some sort of order to give us an idea of each one's strength, or in some cases, lack of strength.
Different combinations of cards produce different types of hands, and some are more likely to be dealt than others:
- Pocket Pair:
- Suited Hand:
- Off-Suit Hand:
AKs = 16 combos in total.
To figure out the number of combos for an off-suit hand, you would be multiplying the (4 various suits)(3 other suits) = 12 combos. For a suited hand, there's only 1 of each suit, equaling 4 combos. To figure out a pair you would use (3x1)+(2x1)+(1x1) = 6 combos.
Now you have an idea of where all those combinations come from.
See this combinations article for more on the mathematics.
The next step is to determine which hands hold the most value and why.
The most obvious answers are
For instance, why is
A9o such a horrible hand to open the raise with UTG?
You may think, "I have an Ace, that’s a good card, I should raise!", but when you open
A9o UTG, there is an extremely high likelihood that a player calling you not only has position on you postflop, but also has a hand that has you crushed in terms of equity (for example if they have a better Ace like
AQ). Both of these things will lead to you leaking money, which is something we want to avoid.
"Ok, so we know we don’t want to open
A9oUTG, then what do we open?”
The answer to this is elastic and will vary from player to player depending on a combination of things:
With all that in mind, we have to start somewhere. And that somewhere for a beginning player, in my opinion, is something around the top
12.5% of hands in No Limit Hold'em.
12.5% of hands can also be expressed as the
166 strongest combos in the game. Those combos are
This is a solid opening range that will help keep you out of tons of difficult spots OOP postflop. The tool I am using to figure out these percentages is a program called PokerStove — it's freeware you can download, and is a must have for anyone looking to improve, or take the game even semi-seriously.
So we have an UTG opening range, now we need an opening range for the remaining positions, MP/CO/BTN/SB. Once again these will vary from player to player and change as you improve, but I have created a list of opening ranges that should work fairly well for players just beginning.
The list is as follows:
Opening Ranges. (6max cash games)
Obviously these numbers aren't the "answer", but they should be a solid starting point for your online poker endeavors.
Over time you will learn that some hands are so close in equity preflop that they are interchangeable. Basically, this means that nobody (theoretically) can quantify whether it is better to open
98s in Middle Position. Some people prefer one hand over the other, some will open both. What works best for you is what should dictate decisions like this.
If you notice in the charts, our opening ranges become wider as we move into later positions.
This is because we can play a wider range more effectively in position as opposed to OOP, so naturally we open more hands as we get closer to the button. At the end of your poker "career" you will make the most money from the latest position, which is the button.
The button also has the most dynamic range of all positions because it is so drastically affected by players in the blinds in un-opened pots. If the players in the blinds are playing too tight, then it's profitable to open almost any hand, because they are not defending their blinds with a high enough frequency to prevent you from showing an immediate profit.
As a result, we should be widening our button opening range dramatically.
I hope this article has given you a better understanding of what hands are suitable to play from varying positions, and how those positions affect our hand selection.
Question everything when learning; don’t take someone's word for it, that’s how you improve. See what works for you, and know why it works for you.
GL everyone! See you at the tables.
