The Ultimate Guide to Poker Range Charts: Crush Preflop Play
Welcome to the definitive guide to understanding and mastering poker range charts in 2025. If you’ve learned the basic rules of No-Limit Hold’em and are ready to move beyond just playing your cards, you’ve come to the right place. Range charts are the single most powerful tool for transforming your preflop game from guesswork into a precise, winning strategy. This guide will teach you how to read them, use them by position, and gain an unbeatable edge over your opponents.
What is a Poker Range Chart?
A poker range chart is a 13×13 grid that visually represents all 169 possible starting hands in Texas Hold’em. It’s a strategic blueprint that tells you the optimal action—raise, call, 3-bet, or fold—to take with each hand from a specific position at the table. Instead of thinking “What should I do with my Ace-King?”, you learn to think in terms of “ranges.” A range is the entire collection of hands you would play in a particular way in a specific situation, which makes you far more difficult for opponents to read.
Quick Facts: Poker Range Charts Explained
Unlike standard casino games where you play against the house, poker is a contest of skill against other players. Concepts like “house edge” and “RTP” don’t apply. Your success is determined by the edge you can create over your opponents. Range charts are a primary tool for building that edge.

How to Play: Reading a Poker Range Chart Step-by-Step
At first glance, a range chart can look intimidating, but it’s simple once you understand its components. Here’s how to decode any preflop poker chart.
- Understand the Grid Layout: The 13×13 grid shows every possible two-card combination.
- The diagonal line from top-left to bottom-right represents pocket pairs (AA, KK, QQ, down to 22).
- Hands above the diagonal are suited hands (e.g., AKs, QJs, 76s), where both cards are of the same suit.
- Hands below the diagonal are offsuit hands (e.g., AKo, QJo, 76o), where the cards are of different suits.
- Learn the Notation: The “s” stands for suited and the “o” stands for offsuit. So, “KQs” means King-Queen of the same suit, while “KQo” means King-Queen of different suits.
- Decode the Colors: Each color on the chart corresponds to a specific action. While color schemes can vary, a common system is:
- Red/Orange: Raise (as the first player to enter the pot).
- Blue/Purple: 3-Bet (Re-raise against another player’s initial raise).
- Green: Call (Call an opponent’s raise).
- Grey/White: Fold.
- Match to Your Position: This is the most critical step. You must use the chart designed for your specific position at the table (e.g., the “Button” chart, the “UTG” chart). A hand that is a standard raise from the Button is an easy fold from an early position.
Betting Actions & Chart Notation
Your range chart will recommend several different actions. Understanding what they mean is key to executing your strategy correctly.
| Action | Meaning & Strategic Purpose |
|---|---|
| Raise (Open-Raise) | You are the first player to voluntarily put chips in the pot (besides the blinds). The goal is to build a pot with a strong hand and thin the field. |
| Call (Cold-Call) | Matching a bet made by a player in front of you. This is generally done with hands that play well post-flop but aren’t strong enough to re-raise. |
| 3-Bet (Re-raise) | Raising after another player has already raised. This is a power move done with your strongest hands (for value) or specific bluffs (to apply pressure). |
| Fold | Giving up your hand. The most frequent and often most profitable action in poker. Disciplined folding is the hallmark of a strong player. |
Strategy Guide: Poker Range Charts by Position
Position is everything in poker. The later your position, the more hands you can profitably play because you have more information about your opponents’ actions. Here is a breakdown of the general strategy for each position in a 6-max game.
UTG (Under the Gun): Playing Tight
As the first player to act preflop, you are in the worst position. You should play an extremely tight and strong range here, consisting of premium pocket pairs, strong broadway hands (like AK, AQ), and some strong suited connectors.
MP (Middle Position): Opening Up a Little
You can add a few more hands to your opening range here compared to UTG, but you still need to be cautious as there are several players left to act behind you.
CO (Cutoff): Applying Pressure
The Cutoff is a powerful position. You can start to open a much wider range of hands to attack the Button and the blinds. This is where you can start playing more speculative hands like suited connectors and suited gappers.
BTN (Button): The Power Position
The Button is the best seat at the table. You are guaranteed to act last on every post-flop street. From here, you should be raising with a very wide range of hands to steal the blinds and control the pot.
SB (Small Blind): A Tricky Spot
The Small Blind is a difficult position. You have to act first post-flop, but you already have half a big blind invested. Modern strategy often involves playing a “3-bet or fold” strategy from here, avoiding calling raises and putting yourself in tough spots.
BB (Big Blind): Defending Your Blinds
When facing a raise, you get to close the action from the Big Blind. Because you already have a full blind invested and are getting good pot odds, you can defend by calling or 3-betting with a much wider range than any other position.
Strategy Guide: GTO vs. Exploitative Play
A poker chart provides a Game Theory Optimal (GTO) baseline strategy. A GTO strategy is perfectly balanced and theoretically un-exploitable. However, most of your opponents don’t play perfectly. Exploitative play means deviating from the chart to take advantage of their specific mistakes.
- Against a “Nit” (Overly Tight Player): If a player in the blinds folds to steals 90% of the time, you should raise with nearly any two cards from the Button, which is much wider than the chart suggests.
- Against a “Maniac” (Overly Aggressive Player): If a player 3-bets constantly, you should tighten the range of hands you call with and be prepared to 4-bet with your premium holdings.
- Against a “Calling Station” (Passive Player): You should avoid bluffing this player. Widen your value betting range and narrow your bluffing range because they are likely to call you down.
Remember: Start with the GTO chart as your foundation. Once you identify a clear weakness in an opponent, you can make a profitable exploitative adjustment.
Poker Range Chart Variations
Not all charts are created equal. You must use a chart that is designed for your specific game format and conditions.
| Game Type | Key Differences & Chart Adjustments |
|---|---|
| 6-Max Cash | This is the most common format online. Ranges are generally wider (you play more hands) because there are fewer players at the table. |
| Full Ring (9-Handed) Cash | With more players, ranges are much tighter, especially from the early positions (UTG, UTG+1, UTG+2). Your opening requirements must be much stricter. |
| Tournaments (MTT) | Charts change dramatically based on stack size. A 40 big blind strategy is very different from a 15 big blind “push/fold” strategy. ICM pressure near money bubbles also heavily influences decisions. |
7 Common Mistakes to Avoid When Using Range Charts
- Using the Wrong Chart for the Game: Applying a 6-max chart in a full-ring game will cause you to bleed chips by playing too loosely.
- Following Charts Too Rigidly (The “Robot” Mistake): Failing to adjust your strategy to take advantage of obvious opponent weaknesses.
- Ignoring Player Tendencies: If the player to your left is a 3-bet maniac, you can’t open the same range as the chart recommends; you must adjust.
- Memorizing Without Understanding the “Why”: Don’t just memorize the grid. Understand *why* A5s is a better open from UTG than KJo. It’s about equity, playability, and blocker effects.
- Not Adjusting for Different Stack Sizes: Especially in tournaments, your preflop strategy must change as your stack size (measured in big blinds) changes.
- Getting Discouraged by Short-Term Results: Poker has variance. You can play a hand perfectly according to the chart and still lose. Trust the process and the long-term profitability.
- Using Charts as a Crutch, Not a Study Tool: The goal is to internalize the concepts so you can make these decisions automatically. Use charts to study away from the table, not just to copy during play.
Choosing the Right Online Poker Room: Key Factors for 2025
When applying your new skills, selecting the right environment is crucial. Instead of recommending specific sites, here are the factors you should consider when choosing where to play.
| Factor | What to Look For |
|---|---|
| Player Traffic | Look for rooms with a high volume of players at your preferred stakes and game types, ensuring you can always find a game. |
| Software & Interface | A clean, stable, and intuitive platform is essential. The software should be reliable and easy to use, especially if multi-tabling. |
| Rake & Rewards | Compare the “rake” (the fee the house takes from each pot). A lower rake and a good rakeback or loyalty program significantly impact your long-term win rate. |
| Game Variety | Ensure the site offers the specific formats you want to play, whether it’s 6-Max NLHE, MTTs, or other poker variants. |
Frequently Asked Questions (FAQ)
Are poker range charts free?
Yes, many high-quality, fundamental starting hand charts are available for free online from reputable poker training sources and community forums. More advanced, solver-generated charts for very specific situations are often part of paid training subscriptions.
How do you memorize poker range charts?
Pure memorization is inefficient. Instead, focus on understanding the structure of the ranges. Start with one position, like the Button, and understand why certain hands are included. Use poker software to quiz yourself. The goal is comprehension, not just rote memorization.
What are the best poker range charts for 6-max?
The “best” charts are those derived from modern GTO solvers. Look for charts from established poker training companies and coaches, as these are considered the industry standard for accuracy and are constantly updated as strategies evolve.
Should I use a poker range chart creator or calculator?
These are two different tools. A chart viewer lets you see pre-solved GTO charts. A range “calculator” or equity calculator is a tool that lets you analyze scenarios by pitting one range of hands against another to see who has the equity advantage. Learning to use charts comes first; equity calculators are the next step in your development.
How do preflop range charts help my post-flop game?
By using a solid preflop chart, you ensure that you arrive at the flop with a stronger, more defined range of hands. This makes your post-flop decisions infinitely easier. You will have fewer difficult spots and be able to connect with boards more effectively, leading to more profitable outcomes.
Responsible Gambling Reminder: Poker is a game of skill, but it’s essential to play within your limits. Always manage your bankroll responsibly and never bet more than you can afford to lose. If you feel you may have a gambling problem, please seek help from a professional organization.
