How to Build Your Own 6-Max Preflop Charts

By Chris Hale · Updated 13 August 2026

Building your own 6-max preflop charts is a powerful way to systematize your early decisions on the poker felt, leading to more profitable and consistent play. Instead of guessing, you’ll have a defined range of hands to play from each position, significantly reducing costly mistakes. This guide will walk you through the process, helping you craft charts tailored to your specific strategies and opponent tendencies, ultimately enhancing your overall win rate.

Understanding preflop ranges is the bedrock of modern poker strategy. In six-max No-Limit Hold’em, a game known for its faster pace and wider starting hand ranges compared to full-ring, mastering these initial decisions is paramount. This is where preflop charts become indispensable tools, providing a structured framework for navigating the complexities of opening, calling, and three-betting before the flop hits.

The journey to creating effective preflop charts is one of continuous learning and adaptation. It requires a solid understanding of fundamental poker concepts such as pot odds, implied odds, and position. By investing the time to build and refine your own charts, you’re not just memorizing a list of hands; you’re developing a deeper intuition for optimal play, which is a hallmark of any successful poker player.

Understanding the Importance of Position

In six-max No-Limit Hold’em, position is king. Your positional advantage dictates the size of your opening range, your three-betting frequency, and your overall profitability. Playing in late position, like the button or cutoff, allows you to see how your opponents act before you must make a decision, giving you a significant informational edge.

When you open from early position (under the gun, for example), you have several players to act behind you. This means you must play a tighter, more premium range of hands, as any hand you open could face a three-bet or a call from players in later positions who have the advantage. Conversely, from the button, you can open a much wider array of hands because you are the last to act preflop, increasing your chances of winning the pot without a showdown or extracting more value when you are called.

The dynamic shifts dramatically as you move around the table. Middle position hands are generally stronger than early position hands but weaker than late position hands. Understanding these positional differences is the first crucial step in constructing a balanced and profitable preflop chart for every seat at the table.

Key Concepts for Chart Construction

Several core poker principles underpin the creation of effective preflop charts. Chief among them is understanding hand strength across different scenarios. Premium pairs like AA, KK, and QQ will always be strong plays, but the profitability of hands like suited connectors or offsuit broadways becomes highly dependent on position and the actions of your opponents.

Pot odds represent the ratio of the current size of the pot to the cost of a contemplated bet. This calculation is vital for determining whether calling an opponent’s raise is mathematically justifiable. For instance, if the pot is 100 chips and your opponent bets 20 chips, the pot becomes 120. If it costs you 10 chips to call, you are getting 120:10 odds, or 12-to-1, meaning you need to win at least 1 in 13 times to break even on a call. This direct calculation influences whether hands with good implied odds should be included in your opening or calling ranges.

Implied odds, while harder to quantify precisely, refer to the potential to win additional chips on later streets if you hit your hand. Hands that can make strong combinations, like flushes or straights, often have good implied odds. This is particularly relevant when considering calls from players who might have stack sizes significantly larger than the current pot, making them amenable to calling with speculative hands that could become very profitable.

Building Your First 6-Max Preflop Opening Ranges

When constructing your opening ranges, begin with the earliest positions. From Under the Gun (UTG) in a 6-max game, you’ll want to open a very tight range, typically focusing on premium pairs (77+), strong aces (AJ+, KQ), and perhaps some Broadway hands (KJ, QJ, etc.). This range might comprise around 15-17% of hands.

As you move to the next position, say Middle Position 1 (MP1), you can broaden this range slightly. You might add medium pairs (44-66), more suited aces (A9s, A8s), and some strong king-high hands. This range might expand to approximately 18-20% of hands. The principle is to open wider as you get closer to the button, as the number of players left to act decreases.

The true expansion occurs in late position. On the cutoff, you can open a significantly wider range, often around 40-45% of hands. This includes a broad spectrum of suited and unsuited connectors, weaker aces, and a host of speculative hands that can be profitable when you have position. The cutoff is a prime spot to apply pressure and steal blinds, making a wider opening range crucial. The button, being the last to act, allows for the widest opening range, often exceeding 50% of hands, as you have the best positional advantage.

Incorporating Three-Betting and Calling Ranges

Beyond just opening hands, your preflop charts should also address how you respond to an opponent’s open-raise. This involves defining your calling range and your three-betting range. Your three-betting range should be a blend of value hands and bluffs. Value three-bets, such as with AA, KK, or QQ, are made with the intention of getting maximum value from a strong hand.

Your bluff three-bets are crucial for balance and for attacking opponents who might be opening too wide. These are often hands with good playability on the flop, such as suited aces (A5s-A2s) or suited connectors (e.g., 76s, 87s). The goal of a bluff three-bet is to get the opponent to fold and win the pot uncontested, or to build a pot when you have a hand that can improve significantly on the flop.

Your calling range is what remains after you’ve selected your opening and three-betting hands. This range is typically more speculative and is heavily reliant on position and pot odds. Hands that play well multi-way or have good implied odds, like suited connectors and smaller pairs, often find a place in your calling ranges, especially when you have favorable pot odds or are in position.

Worked Example: Three-Betting from the Cutoff

Let’s consider a practical scenario. You are on the Cutoff (CO) with a stack of 100 big blinds (BB). An opponent from Middle Position 1 (MP1) opens to 2.5 BB. The pot is now 5.5 BB (2.5 BB from MP1 + 0.5 BB SB + 1 BB BB). You know MP1 is a relatively tight player, opening about 18% of hands.

You are holding A♥ K♦. This is a strong hand that you would definitely open with from the CO. Against an MP1 open, A♥ K♦ is a prime candidate for a three-bet for value. You decide to three-bet to 7.5 BB (2.5 BB initial raise + 5 BB). The goal here is to isolate the MP1 player, gain initiative, and potentially extract more value with a strong hand.

If MP1 folds, you’ve won 8 BB (2.5 BB open + 0.5 BB SB + 1 BB BB + 4 BB from your 3-bet that didn’t get called). If MP1 calls your 7.5 BB three-bet, the pot will be 20.5 BB (2.5 BB open + 0.5 BB SB + 1 BB BB + 7.5 BB from MP1 + 7.5 BB from you). You’ll then be playing post-flop in position with initiative. This clear decision-making process, driven by hand strength, position, and the opponent’s tendencies, is what effective preflop charts enable.

Refining Your Charts with Data and Tools

While manual chart creation is beneficial for understanding, modern poker players often leverage software to refine their strategies. Tools like PioSOLVER, GTO+ (for solvers), or even simpler preflop chart builders can help you analyze hand ranges and simulate game scenarios. These tools use complex algorithms to calculate optimal frequencies for various actions based on different equity distributions and game trees.

Analyzing your own hand histories using tracking software like PokerTracker 4 or Holdem Manager 3 is another critical step. These programs provide detailed statistics on your play, highlighting areas where you might be losing money or making suboptimal decisions. You can identify if your opening ranges from certain positions are too wide, if you’re not three-betting enough as a bluff, or if your calling ranges are too loose.

Consistency is key. Once you’ve built your initial charts, stick to them. Over time, as you gather more experience and observe specific opponent tendencies, you can make educated adjustments. The most effective charts are dynamic; they evolve with your understanding and the ever-changing landscape of online and live poker. Building and refining these charts is an ongoing process that significantly contributes to long-term profitability.

Putting Your Charts into Practice

The ultimate test of your preflop charts is their application at the tables. It’s one thing to create a theoretically sound chart; it’s another to execute it consistently in real-time. Start by focusing on one position or one aspect of your play, perhaps your opening ranges from the cutoff. Try to adhere strictly to your chart for a significant number of hands, say 500 or 1000.

Pay close attention to how your play feels. Are you comfortable with the hands you are playing? Are you finding yourself in favorable situations more often? Observe your opponents’ reactions. If you notice a particular player folding too often to your three-bets, you might slightly increase your bluffing frequency with appropriately chosen hands. Conversely, if a player is consistently calling your opens lightly and you struggle post-flop, you might tighten up your opening ranges.

Remember that charts are guidelines, not rigid rules. There will be situations where deviating from your chart is the optimal play. This might happen if you have unusual reads on specific opponents, or if the table dynamics have shifted dramatically. However, the vast majority of the time, your charts will provide the most profitable and consistent course of action. Mastering them provides a significant edge.
