How to Build Optimal Poker Ranges From Scratch (2026)

Why Your Poker Ranges Are Probably Costing You Money Right Now

If you cannot write out your standard opening range from every position without hesitating, you have already lost money at the table. This is not a drill. It is not an exaggeration. Your poker ranges are the foundation of every decision you make post-flop, and if that foundation is made of guesswork and gut feeling, your entire game is built on sand. I have watched countless players at every stake level from 2NL to 5/10 live struggle with this exact problem. They know that ranges matter. They have seen solver outputs. They have read forum posts about optimal frequencies. But when the chips are flying, they are making it up as they go. That stops today.

Building optimal poker ranges from scratch is not about memorizing what a solver spits out. It is about understanding why certain hands belong in certain ranges and why others do not. It is about internalizing the logic so deeply that you can adjust in real time when the game dynamics shift. A memorize-and-apply approach will fail you the moment someone adjusts their strategy or the table texture changes. A logic-based approach will serve you for your entire poker career. This article is going to walk you through the entire process, from the fundamental concepts to specific range construction for each position at a full ring table. You will understand not just what to play but why you are playing it.

The Core Logic You Must Understand Before Building Anything

Before we touch a single hand or write a single range, you need to understand the three forces that drive range construction. These are not suggestions. These are the laws of the universe as far as your range decisions are concerned. Violate them and you will bleed money. Master them and you will have a framework that works in any game, at any stake, against any opponent type.

The first force is positional advantage. In poker, position is the closest thing to a free lunch that exists. When you act last, you have information your opponents do not have. You see their decisions before you must make yours. This means you can play more hands profitably from late position because the information advantage compensates for the marginal strength of certain holdings. It also means your opponents must play defensively from early position, which opens up exploitation opportunities for you when you are in the blinds or on the button. Every range you build must account for position as its primary organizing principle.

The second force is dead money and initiative. When you open raise, you are often winning the pot immediately simply because players behind you fold. This is called taking down the dead money. The amount of dead money in the pot relative to the size of your raise determines how often your opponents must defend to prevent you from printing money with any two cards. A standard open raise size of around 3 to 3.5 big blinds at a 9-max table means you are typically risking 3 to win around 1.5 in immediate dead money. You need to win the pot immediately less than 67 percent of the time to profit from a blind steal, which means your opponents cannot simply call with everything and stop you. This is why your positional stealing ranges can be extremely wide. The math supports it.

The third force is post-flop playability. Some hands are easier to play than others after the flop. Pocket pairs have set-mining potential and can flop huge. Suited connectors can make straights and flushes and play well multiway. Offsuit broadway hands have high card value but are structurally weaker. When you construct ranges, you need to weight toward hands that allow you to continue comfortably across a wide range of flops rather than hands that require specific textures to be profitable. This is where many players go wrong. They include hands that look good pre-flop but become nightmare scenarios on most flops they encounter.

Constructing Your Pre-Flop Ranges Position by Position

Now we get into the actual construction. I am going to walk you through a standard full ring table setup assuming standard 100 big blind effective stacks. These ranges are not the be-all and end-all. They are a starting framework based on solid poker logic that you can then adjust based on your specific game dynamics. But if you have nothing right now, if you are truly building from scratch, this is where you start.

Under the gun is the most difficult position at the table. You have eight players left to act, any of whom could hold premium hands. You must play tight here. Your opening range from UTG in a 9-max game should look something like this. You open with pocket pairs 77 and above. You open with suited connectors down to 54 suited if you are more aggressive, but T8 suited and above is the conservative baseline. You open with all suited broadway hands, which means TJs, TQs, JQs, and AK. You open with AK offsuit. You open with AQ offsuit. You open with KQ offsuit. Everything else folds. This sounds tight and it is, because it should be. You are opening from the hardest position with hands that have the equity to survive against players who have position on you and are likely to have strong ranges themselves.

From middle position, which I define as seats three through five in a 9-max, you can start expanding. You add pocket pairs 66 and above. You add suited connectors down to 43 suited. You add suited one-gappers like 75 suited and 86 suited if you are on the aggressive side. You add more offsuit broadway hands like QJ offsuit and AJ offsuit. The goal is to have roughly 15 to 18 percent of hands from these positions, which is about 3 to 4 times the UTG range. The reason you expand is that you still have position on the players behind you and more dead money to steal, but you still need to be careful because early position players have already acted and could hold strong hands.

Cutoff and button are where the real money is made in modern poker. These positions have such massive positional advantage that you can open extremely wide. From the cutoff, you are looking at roughly 30 to 35 percent of hands. You open almost all pocket pairs. You open most suited hands down to 32 suited and everything with a flush draw potential. You open suited connectors and one-gappers. You open most suited broadway hands. You open a significant portion of your offsuit broadway holdings. You are still not opening garbage like 32 offsuit, but you are in a range that looks very different from early position. From the button specifically, you can push toward 50 percent of hands or even higher depending on the players in the blinds. The button has position on everyone and will act last post-flop in almost every multiway pot that develops. This is the most profitable seat at the table, and your range should reflect that.

The small blind and big blind are special positions because they are already invested in the pot. This changes the math considerably. When you defend your blind, you are usually getting a better price than the mathematical fair price because of the dead money already in the pot. However, you are out of position post-flop, which has real value. Your defending ranges should be wider than your opening ranges from the same position but not so wide that you are calling with hands that cannot realize their equity properly. A common mistake is calling too wide from the big blind against steals, which puts you in difficult spots post-flop with hands that are hard to play out of position.

How to Adjust Your Ranges Against Specific Opponent Types

The ranges I described above are a baseline. They are what you do when you have no information on your opponents. But poker is not played in a vacuum. You are playing against humans, and humans have tendencies. The best players in the world adjust their ranges in real time based on who they are playing against. If you are not doing this, you are leaving money on the table.

Against tight players who open only premium hands, you should defend your blinds much more conservatively. The tighter their range, the more often they have a real hand when they bet, and the less profitable it is to call with marginal holdings that need to hit the board to win. You also 3-bet more often with your premium hands because tight players are more likely to fold marginal holdings, and you can sometimes take down the pot immediately. Against a 10 percent opening range from early position, for instance, their value range is extremely narrow, and you can 3-bet aggressively with your best hands because they will fold too often.

Against loose players who open too many hands, the adjustment is different. You 3-bet more selectively because their calling ranges are wide and your premium hands will get action. You defend your blinds more selectively because they will continuation bet too often and you will be playing out of position with hands that cannot continue. You also tighten your opening ranges from early position because loose players behind you are more likely to call with dominated hands that could crack your premium holdings. The key is that every adjustment you make is a reaction to a real tendency you have observed, not a hypothetical one.

Stack sizes also change your ranges dramatically. When stacks get shallower, around 50 big blinds or less, pocket pairs and suited connectors decrease in value because set mining and multi-card draws become less viable. High card hands like AK and AQ increase in value because they play well as short stacks and can often get all-in pre-flop or flop top pair against worse hands. When stacks get deeper, above 150 big blinds, you can play more speculative hands because the implied odds are enormous. A suited connector that makes a flush or straight can win a massive pot. The depth of play also means that position becomes even more valuable, so your late position ranges should expand further.

Balancing Your Ranges and Avoiding the exploitation trap

There is a temptation when you first learn about range construction to go too far in one direction. Either you play like a robot and never deviate from your baseline ranges, or you adjust so aggressively to every opponent that your own strategy becomes chaotic and exploitable. The truth is somewhere in between, and finding that middle ground is what separates winning players from the rest.

Balance matters most when you are playing against opponents who are skilled enough to notice imbalances and punish them. If you never bluff from early position but always value bet your strong hands, good players will stop calling your value bets because they know you only bet with nuts. If you always check your medium strength hands from the big blind but bet your strong and weak hands, good players will exploit your check by betting with anything that has a chance to win. The solution is to maintain roughly similar betting frequencies across your entire range, which means betting some medium strength hands sometimes and checking some strong hands sometimes.

But balance is not the goal. Winning is the goal. Against weak players who are not paying attention to your range composition, pure exploitation is always better than balance. If a recreational player never folds top pair, you should value bet thinner and bluff less. If they fold too much, you should bluff more and use smaller bet sizes to induce calls from worse hands. The moment you sit down at a table full of thinking players who are taking notes, that is when you tighten up and maintain proper frequencies. Your poker ranges are a tool for extracting money, not a philosophical exercise in game theory perfection.

The final truth about building ranges is that it is never finished. The game evolves. Players get better. Tendencies shift. What works at 2NL in 2026 will not work exactly the same way at 50NL. Your ranges must evolve with the game and with your skill level. Start with a solid baseline. Learn why each hand is in each range. Test it at the table. Adjust based on results. The players who treat poker as a craft, who are never satisfied with their current understanding, are the ones who keep improving. Your ranges are a living document, not a fixed law. Treat them accordingly and you will never stop getting better at this game.
