Preflop charts are one of the fastest ways to clean up your poker decision-making, but they only help if you understand what they are actually teaching. This guide explains how position-based preflop ranges work in no-limit Texas Hold'em cash games, with practical starting charts for UTG, cutoff, button, small blind, and big blind play. The goal is not to memorize every combo like a robot. It is to give you a clear structure you can use at the table, then adjust as stakes, rake, player pool tendencies, and table conditions change.
Overview
If you have ever felt lost deciding whether to open KJo from early position, defend A5o in the big blind, or raise a suited connector on the button, position is the missing framework. Strong players do not choose hands in isolation. They choose them based on where they sit, how many players are left to act, how often they expect to get called or 3-bet, and how well a hand performs after the flop.
That is why preflop charts by position matter. They turn a messy list of possible hands into a practical system. In most standard six-max cash games, your opening ranges should get wider as you move closer to the button. Early position requires discipline because several players can still wake up with stronger hands. Late position gives you more freedom because you act with more information and can win more pots uncontested.
This article uses a simple baseline model for typical online cash games. Think of it as a starting point rather than a universal law. Tournament stack depths, ante structures, rake, and blind levels can all shift ranges. So can player pool habits. Still, if you learn these baseline patterns, your overall online poker strategy becomes much more stable.
One more note before the charts: a range is not just a collection of "good hands." It is a balanced group of hands that can win in different ways. Some hands dominate weaker calling ranges. Some make strong top pair. Some realize equity well in position. Some function as semi-bluff candidates. Understanding those jobs is what makes a chart useful beyond memorization.
Core framework
Here is the simple positional rule that drives almost every solid preflop chart: the earlier your position, the tighter and stronger your range should be. The later your position, the more hands you can profitably open because fewer players remain to act and your postflop advantage improves.
Below is a practical baseline for six-max no-limit Hold'em cash games with 100 big blind stacks. This is a guide, not a solver printout. It is built to be readable, teachable, and easy to revisit.
UTG opening range
Your UTG opening range should be the most disciplined at the table outside of unusual game conditions. A strong baseline includes:
- All pairs: 22+
- Strong suited aces: A5s-AKs
- Strong offsuit aces: AJo+ and AQo+
- Broadway suited hands: KTs+, QTs+, JTs
- Broadway offsuit hands: KQo
- Strong suited kings: KJs+, sometimes KTs
This range works because it avoids too many dominated offsuit hands and keeps a good mix of value hands, board coverage, and hands that can continue versus a 3-bet. The big leak in early position is adding too many hands that look pretty but perform poorly, such as KJo, QJo, A9o, or weak suited kings.
Cutoff opening range
The cutoff is where many players begin to earn their edge. You have only the button and blinds behind you, so you can widen your opening range meaningfully. A practical cutoff range includes:
- All pairs
- Most suited aces: A2s+
- Offsuit aces: A9o+
- Suited broadways: K9s+, Q9s+, J9s+, T9s
- Offsuit broadways: KTo+, QTo+, JTo
- Suited connectors and one-gappers: 65s+, 75s+, 86s+, 97s+
- Some suited kings and queens with postflop playability
The cutoff rewards aggression, but not carelessness. You are stealing more often here, yet you still face a button who may defend or 3-bet actively. If that player is strong and aggressive, trim the weakest offsuit opens and keep more suited hands that realize equity better.
Button range chart
Your button range chart should be the widest opening range at the table in most cash-game setups. You have position on both blinds postflop, and many pots end before showdown. A standard baseline can include:
- All pairs
- All suited aces
- Most offsuit aces
- Most suited kings
- Many offsuit kings: K8o+ as a practical baseline in softer games
- Most suited queens and many offsuit queens
- Most suited connectors and many suited one-gappers
- Many suited jacks and tens
- Selected offsuit connectors and broadway-style hands that retain playability
The temptation on the button is to open any two cards. That can work in very soft games against overfolding blinds, but it is not a strong baseline. Good button opens still need some postflop utility. Weak offsuit trash hands often lose their advantage once called. A clean late-position strategy beats a reckless one.
Small blind opening range
The small blind range is tricky because you act first after the flop when called. Even though only the big blind remains preflop, the postflop disadvantage is real. That means your small blind opening strategy is not simply "button lite." In many games, a practical small blind opening or raise-first-in range includes:
- All pairs
- All suited aces
- Most offsuit aces down to around A8o or A9o as a baseline
- Many suited broadways
- A tighter set of offsuit broadways than the button opens
- Suited connectors and suited one-gappers that can semi-bluff well
- Fewer weak offsuit holdings that realize equity poorly out of position
Some players use a mixed strategy from the small blind, raising some hands and limping others. That can be effective, especially in softer live games or certain rake environments. But if you want a simple online baseline, use a raise-first-in strategy with a tighter construction than the button. Prioritize hands that can continue against a 3-bet or play well after the flop.
Big blind defense chart
The big blind defense chart is less about opening and more about deciding when to call, 3-bet, or fold against steals. Because you already have one blind invested, you can defend wider than many players expect. But wide does not mean automatic. You should defend based on opener position, sizing, stack depth, and your postflop edge.
As a baseline versus a button open, the big blind can continue with:
- All pairs
- Most suited aces
- Many offsuit aces
- A wide set of suited kings, queens, and jacks
- Broadway offsuit combinations with decent top-pair value
- Most suited connectors and many suited one-gappers
- Some weaker suited hands that can realize equity well against small opens
Against an early-position open, that defense should tighten sharply. Hands that are easy calls versus the button become folds versus UTG. Position and opener strength matter just as much as your hole cards.
A useful rule for big blind play: defend more versus smaller opens and later positions, defend less versus larger opens and earlier positions. If an opponent opens too large or the rake is high, marginal calls lose value quickly.
Why suited hands appear so often
If you compare these ranges, you will notice that suited hands survive the cut more often than similar offsuit hands. That is because suited hands make stronger draws, can semi-bluff on more boards, and usually realize equity better. A hand like A5s can open from early position not because it is a powerhouse preflop, but because it has wheel potential, nut-flush potential, and useful blocker effects. A hand like A5o has far fewer paths to profit.
How to use charts without becoming rigid
The best use of a chart is to build instincts. If you regularly study why a hand belongs in a range, you begin to make strong decisions even when the exact spot changes. That matters in real games, where stack sizes, opens, and player tendencies are never perfectly standard. If you want to deepen this kind of structured study, it helps to compare your baseline approach with modern tools and training platforms. Our guide to best poker training sites and tools is a useful next step.
Practical examples
Charts become much more useful when you apply them to common hands. Here are simple examples of how position changes a decision.
Example 1: KJo
UTG: Usually fold. KJo is often dominated when called and performs poorly against stronger ranges.
Cutoff: Often open. Fewer strong hands remain behind, and it can win preflop often enough.
Button: Clear open in most games.
Small blind: More marginal than on the button because you will be out of position postflop.
Example 2: A5s
UTG: Often open as part of a disciplined suited-ace mix.
Cutoff and button: Easy open.
Versus a late open from the big blind: Often a defend, and sometimes a 3-bet candidate depending on tendencies and sizing.
Example 3: 76s
UTG: Usually fold in standard rake-heavy online games.
Cutoff: Often open.
Button: Standard open.
Small blind: Playable, but less attractive than on the button because of positional disadvantage.
Big blind versus button min-open: Common defend.
Example 4: QTo
UTG: Fold.
Cutoff: Mix depending on game quality and players behind.
Button: Often open.
Big blind versus cutoff: Borderline defend depending on sizing and skill edge.
Notice the pattern. The hand itself matters, but the table location often matters more. This is the core lesson behind preflop ranges.
You can also think in terms of player type. Against tight blinds, widen your button steals. Against loose callers, prefer hands with stronger top-pair value and better postflop clarity. Against aggressive 3-bettors, tighten weak opens and continue with hands that can withstand pressure. Good charts are not frozen; they are anchored.
That flexibility should also connect to bankroll discipline. If you are playing stakes where every preflop mistake feels expensive, your decisions will become emotional and inconsistent. A stable strategy works best when paired with sensible limits, so it is worth reviewing bankroll basics in our guide on how to set a gambling budget and bankroll rules.
Common mistakes
The most common preflop leaks are not exotic. They are simple range errors repeated hundreds of times.
Opening too wide from early position
Many players treat UTG like the cutoff. That creates difficult postflop spots with hands that are too easily dominated. If your early-position range contains lots of offsuit broadways and weak aces, tighten up first before trying anything advanced.
Playing the button too passively
Some players understand that position matters, then still fail to attack enough from the button. If the blinds fold too much, you should be opening aggressively with a coherent late-position range. Leaving those steals on the table is a direct loss.
Defending the big blind without a plan
Calling because you are "priced in" is not enough. The big blind can defend widely, but your range should still reflect opener position and sizing. If you regularly call with weak offsuit hands versus early opens, you are likely donating chips.
Ignoring postflop realization
Not all hands with similar raw equity are equal. Suited hands, connected hands, and blocker-heavy hands often realize equity better than weak offsuit hands. That is why charts favor them so often.
Memorizing combos without understanding purpose
If you only memorize charts, you may freeze when stack sizes change or table dynamics shift. Ask what job each hand performs. Is it a value open, a steal, a defend, a 3-bet bluff candidate, or a hand that benefits from position? That question turns charts into durable skill.
Using one chart for every format
Cash games, short-stacked tournaments, ante formats, and live games with different rake all require adjustments. Even among real money poker sites, structures and player pools vary enough that a single static chart can become misleading.
When to revisit
Preflop charts are worth bookmarking because they should be revisited whenever the underlying conditions change. That is the evergreen value of this topic: the framework stays useful, but the exact edges move.
Review your ranges when:
- You switch from full ring to six-max, or from cash games to tournaments
- You move up or down in stakes and the player pool becomes more aggressive or more passive
- Rake, ante structure, or effective stack depth changes the profitability of marginal opens and calls
- You start facing frequent 3-bets from the blinds or unusually tight blind defense
- You begin using new study tools, charts, or solver-based training methods
A practical way to keep this useful is to build your own range notes. Start with five headings: UTG, cutoff, button, small blind, big blind. Under each, list hands you are confident opening, hands you are unsure about, and hands that consistently lose money in your database or session review. Then compare those notes to a structured baseline and make one small adjustment at a time.
If you want a simple action plan, use this one:
- Memorize a tight, clean UTG range first.
- Add a wider cutoff range once early-position errors drop.
- Practice aggressive but disciplined button opens.
- Treat the small blind as its own category, not a copy of the button.
- Study big blind defense by opener position and sizing.
- Recheck your ranges every time the format or pool changes.
That process is far more valuable than chasing a perfect static chart. Strong preflop play is built through repetition, review, and adjustment. Use these ranges as a dependable baseline, then refine them as your games evolve.
