If you've already read about which hands are worth playing preflop and checked out how starting hand win rates work, you're ready for the next step: building a position-based preflop range. Knowing which hands to play is only half the equation — knowing when to play them based on where you're sitting is what separates break-even players from consistent winners.

Why Position Changes Everything Preflop

In Texas Hold'em, position is permanent information. Once the cards are dealt, the player on the Button always acts last postflop — in every single betting round. That positional advantage is so powerful that you can profitably play a significantly wider range of hands from late position than you ever could from early position.

Think of it this way: when you act first, you have no idea what the players behind you will do. When you act last, you've seen everyone else's decision before you have to commit a single chip beyond the flop. That extra information is worth real money over thousands of hands.

Key principle: The later your position, the wider your opening range can be. Early position demands tight, strong hands. Late position rewards aggression and hand variety.

Positions at a 6-Max Table

nlh.poker uses 6-max tables only (up to six players). Before we talk ranges, lock in the seat names. From the first player to act preflop clockwise to the Button:

With fewer seats than full-ring, UTG is still the tightest opening seat — but it is wider than UTG at a 9-handed table because only five players act after you, not eight. The same rule holds: the later your position, the wider your range can be.

Understanding "Range" vs. "Hand"

A hand range is the full set of hole-card combinations a player might hold in a given situation. Instead of thinking "I have Ace-King," a range-aware player thinks: "From UTG, I raise with AA, KK, QQ, JJ, TT, AKs, AQs, AKo — and nothing else." That collection of hands is your UTG range.

Ranges are often described by what percentage of all possible starting hands they include. A 162-combo rangecovers roughly 10% of all 1,326 possible starting hand combinations. Here's a quick reference:

Opening Ranges by Position (6-Max)

The following ranges are solid starting points for 6-max with a 2.5–3bb open raise. Treat them as a foundation to build on, not rigid rules.

Early Position: UTG (~18–20%)

From UTG you still have five players behind you, so open tighter than at MP or later — but not as rock-tight as UTG at a 9-handed table. A typical 6-max UTG open includes:

Those suited wheel aces are also natural 3-bet bluff candidates later — same blocker logic applies when you re-raise. That is why charts pair them with UTG opens even though they look weak in isolation.

What to fold from UTG: Small pairs (22–66), weak suited connectors, most weak Ax (A9o, A7o), and offsuit broadways like KJo or QJo. These hands play poorly when you're first to act with five players left.

Middle Position: MP (~22–25%)

With one fewer player behind you than UTG, you can add more pairs, suited broadways, and suited connectors.

• Add pairs: 66+ (opens down to 66 from MP)
• Add suited aces: ATs+
• Add suited broadways: KJs+, QJs, JTs
• Offsuit broadways: AQo+, KQo

Opening only TT+, AJs, and KQs from MP is usually too tight for 6-max — you will miss profitable spots. Use the percentages above as a sanity check, not a ceiling.

Late Position: Cutoff (~38–42%)

The Cutoff is the first truly wide-range opening seat. You're only behind the Button and Blinds. Modern solver charts open far wider from the CO than older “~30%” teaching charts — in practice, a standard CO open is closer to 40% of hands. A representative GTO-style CO range looks like this:

• Pairs: AA–33 (22 is typically a fold)
• Suited aces: A2s–AKs — almost all of them
• Suited kings: K2s–KQs — nearly all (K2s is marginal)
• Suited queens: Q2s–QJs — Q4s and below are sometimes mixed/folded
• Suited jacks: J4s–JTs (J3s and below fold)
• Other suited: T5s–T9s, 95s–98s, 87s, 86s, 76s, 75s, 65s, 54s
• Offsuit: AJo+, KQo, KJo, KTo, QJo, QTo, JTo, K9o, Q9o, and some A9o–A5o (mixed)

If your CO range still stops at 44+ and A7s, you are opening too tight for 6-max. The CO is already stealing territory — suited wheel aces, low pairs, and broad suited hands all belong in the mix.

Late Position: Button (~52–55%)

The Button is the most profitable seat at the table. You are always last to act postflop. The BTN opens wider than the CO, but the gap is smaller than many beginners expect — you are mostly adding a thin layer of marginal hands on top of an already-wide ~40% CO baseline, not doubling your range overnight. Solver charts land around 52–55% from the BTN in standard 6-max spots — wider than CO, but not the ~60%+ some old charts implied.

What the BTN adds on top of a typical CO range (solver diff):

• 22 — the main pocket pair the CO folds
• Suited: Q2s; J3s–J2s; T4s and below (T3s, T2s — often mixed)
• Offsuit (mostly mixed opens): Q8o, J8o, T8o; A3o; occasional K7o

Do not list J9o, T9o, or 98o as BTN-only adds — in modern solver ranges they are already CO opens. The BTN increment is smaller and more specific than “every weak connected hand.”

What still folds at the BTN (same as CO): T2s–T3s are often still out; most very low offsuit hands (72o, 83o, K5o, etc.) remain folds. The BTN is wide, not random.

The Blinds: A Special Case

The Small Blind and Big Blind are unique: you've already invested chips, but you'll act first on every postflop street. That's a brutal combination.

Small Blind (~35–45%, depends on BB)

The SB is the worst position in poker — you act first on every postflop street. When everyone folds to you, you can open wider than UTG but usually not as wide as the BTN. How wide you open from the SB depends heavily on how the BB defends. Against an over-folding BB, opening near 50% can be fine; against a strong defender, tighten toward ~35%. When facing raises, play tight from the SB and lean toward 3-betting or folding rather than calling.

Big Blind: Defense and 3-Betting

The BB is the only position that gets a "discount" — you've already posted one big blind, so your pot odds to call a single raise are better than anyone else's. This means the BB should defend wider than any other position against single raises.

A good rule of thumb: against a BTN open of 3bb, you're getting roughly 2:1 pot odds, which means you only need ~33% equity to break even. That justifies calling with many suited hands, small pairs, and connected hands you'd never play from UTG.

However, "defending wide" from the BB does not mean calling every raise. Against an UTG open (very strong range), your BB calling range should be tight — something like TT+, AQs+, AKo, KQs. Against a BTN steal, your defending range explodes to include hands like 54s, 75o, and K5s.

3-Betting Ranges: When to Re-Raise Preflop

A 3-bet is a re-raise over an open raise. Your 3-betting range should have two components:

A balanced 3-bet range should include both value hands and bluffs — roughly 2:1 or 3:1 value-to-bluff ratio depending on position and opponent tendencies. Flat-calling with KK or AA (the "slowplay trap") and 3-betting hands like A5s as bluffs are both important tools.

Calling vs. 3-Betting vs. Folding: A Simple Decision Tree

When facing an open raise, most decisions boil down to three choices. Here's a framework:

1. 3-Bet: Your hand is in your value range (AA–JJ, AK, etc.) OR it's a strong bluff 3-bet candidate (A5s, A4s from the BTN/CO). Raising protects your range and wins the pot with fold equity.
2. Call (Flat): You have a speculative hand with good implied odds (small pairs, suited connectors) and position on the raiser. Flatting with TT or AQs in position against a CO open is also reasonable.
3. Fold: Your hand doesn't meet the equity threshold for calling given the pot odds, OR you're out of position with a marginal hand that will be hard to play well postflop.

A common beginner mistake is calling too often with medium-strength hands out of position. When in doubt and out of position, fold or 3-bet — don't just call.

Common Mistakes to Avoid

• Playing the same range from every position. This is the single biggest leak for beginners. UTG and BTN ranges look completely different — and they should.
• Limping (just calling the big blind) from any position. Open raise or fold — never limp. Limping surrenders initiative and allows the BB to see a cheap flop with any two cards.
• Over-defending the BB. Yes, you have good pot odds, but calling with 83o or J4o still loses money because those hands can't make strong enough hands often enough.
• Cold-calling 3-bets too wide. When someone 3-bets you, the pot odds shift dramatically. Tighten your continuing range substantially, especially out of position.
• Not adjusting to opponents. These ranges are baselines. Against a tight nit who only 3-bets QQ+/AKs, you can fold JJ preflop. Against a maniac, widen your 3-bet value range.

Next Steps: Deepening Your Range Knowledge

Position-based ranges are the skeleton of a solid preflop strategy. Once you're comfortable with opening frequencies, explore these related concepts:

• Preflop Win Rates Explained — how equity translates into long-run profit for each starting hand

As you gain experience, you'll start to internalize these ranges and adjust them in real time based on stack depth, opponent tendencies, and table dynamics. On nlh.poker's 6-max tables, use the position-based open frequencies in this article as your baseline. The foundation never changes: position is the single most important factor in deciding which hands to play preflop. Master that principle and everything else becomes much easier.
