Preflop Opening Ranges by Position: 6-Max Guide

Nearly every winning online poker player shares one habit: they know, before the cards are dealt, which hands they will open from each seat. Preflop opening ranges are the foundation of a solid game, and they matter even more when you are grinding volume to clear a welcome offer. Whether you are playing at a top-rated poker bonus site or testing a new room with a fresh deposit, a clear opening plan keeps you out of expensive trouble and puts you in profitable spots more often.

This guide walks through sensible opening ranges for 6-max cash games at roughly 100 big blinds deep. These are simplified, solver-informed starting points rather than a rigid chart. Treat them as a baseline you can tighten against aggressive tables and loosen against passive ones.

Why position drives everything

Position is the single biggest edge in no-limit hold'em. Acting last means you see what your opponents do before you commit more chips, which lets you bluff more effectively, value bet more thinly and control the size of the pot. Because the button acts last on every postflop street, it is by far the most profitable seat, and your opening range there should be the widest of the table.

The flip side is that early positions are punished. When you open from under the gun, up to five players still have to act behind you, and any one of them can wake up with a strong hand. That is why a good opening strategy tightens as you move toward the front of the table and widens as you approach the button.

Under the gun: tight and disciplined

In a 6-max game, under the gun is the first seat to act and the toughest place to open. A reasonable range includes the strongest pairs, the best broadway hands and a few suited hands with good playability. Think of it as roughly 15 to 18 percent of hands.

• Pairs: 77 and higher, with some players adding 66 and 55 as pure set-mining plays against passive opponents.
• Suited aces: A2s through AKs. The low suited aces serve as bluff candidates because they block strong hands and can make nut flushes.
• Suited broadways: KQs, KJs, QJs, JTs and often KTs and QTs.
• Offsuit broadways: AKo, AQo, AJo and KQo, with ATo borderline.

Resist the temptation to open weak offsuit hands from this seat. A hand like K9o looks tempting but regularly runs into dominating holdings and leaves you out of position against a 3-bet.

Hijack and cutoff: widening the range

As the number of players left to act shrinks, your range should grow. The hijack, the seat two to the right of the button, can open around 22 to 25 percent of hands. Add smaller pairs like 44 and 33, more suited connectors such as T9s, 98s and 87s, and weaker suited broadways like Q9s and J9s.

The cutoff widens further to about 28 to 32 percent. Here you can include suited one-gappers like J8s and T8s, extra suited aces and kings such as K8s and K7s, and offsuit hands like KTo and QJo. The cutoff is also the seat where you begin applying real pressure on the button and blinds, so your opponents' tendencies matter. Against a button who 3-bets frequently, trim the marginal offsuit hands. Against a passive button, open wider and collect the blinds.

The button: your most profitable seat

The button can open somewhere between 45 and 55 percent of hands depending on the table. Only the two blinds remain to act, and you will have position on whoever calls. Almost any suited hand is an open, most connected hands are an open, and a large share of offsuit broadways and ace-x hands qualify too.

That does not mean you should open absolutely everything. Weak offsuit trash like 72o and 83o still belongs in the muck. The goal is to include hands that can make a decent pair, a flush draw or a straight draw, because those hands are what let you win pots when the blinds defend. Stealing the blinds is also where a lot of steady profit comes from. If you want to refine that part of your game, our guide to blind stealing from the button and cutoff goes deeper.

The small blind: a tricky spot

The small blind is the most awkward position because you will be out of position for the rest of the hand against the big blind. Many strong players use a raise-or-fold approach when the action folds to them, with a raise size of about 3 big blinds to discourage easy defending. Others mix in some limping with weaker hands. Whichever approach you choose, keep your range polarized and avoid building large pots with marginal holdings when you have no positional advantage.

How rake and bonuses affect your ranges

Rake is the quiet force that shapes marginal opens. At higher rake structures, thin opens from early position become less valuable because a portion of every pot is taken before it reaches the winner. That is one reason it pays to understand how poker rake works at the rooms you play.

Bonuses and rakeback soften that cost. If a room returns a meaningful share of your contributed rake through rakeback or a releasing welcome offer, the real price of playing a marginal hand drops. That does not turn a losing opening range into a winning one, and it should never be an excuse to play junk, but it can make borderline opens from the cutoff and button slightly more attractive. Before leaning on that logic, read how different bonus types work so you know what portion of rake actually counts toward your offer.

Adjusting to the table in front of you

Charts are a starting point. Real tables vary. If the players behind you 3-bet often, tighten your opens that cannot comfortably call a 3-bet. If the blinds fold too much, widen your steals. If a loose-passive player sits on your left, you can open slightly wider from every position because they will give you action with worse hands.

Keep notes and review your sessions. Mistakes in opening ranges, such as opening too loose from early position or too tight on the button, tend to show up clearly in your results over a few thousand hands.

Put it into practice

Start by memorizing a simple chart for each seat and playing it faithfully for a few sessions. Once the basics feel automatic, begin making small, deliberate adjustments based on your opponents. Pair that discipline with a smart deposit, and you give yourself the best chance of turning bonus clearing into real profit.
