Cash Game Preflop Strategy: GTO Ranges for 6-Max
Quick answer: In 6-max cash games, GTO opens 14–16% from UTG expanding to 40–45% on the button, with 2.2–2.5bb sizing. The core discipline is playing tight in early position and wide in late position — and knowing exactly which hands belong where. Here is the complete framework.
How cash game preflop strategy differs from tournaments
In a tournament, the blinds increase, your stack shrinks relative to the pot, and ICM pressure forces you to tighten up near the money. Cash games have none of that. The blinds stay constant, you can top up to 100bb anytime, and the only thing that matters is making the highest expected value decision on every hand.
That difference changes preflop strategy in two key ways. First, implied odds are much higher in cash games — your opponent has deep chips to pay you off when you hit a set or a flush. This makes speculative hands like small pocket pairs and suited connectors more profitable to open and call with from the right positions. Second, without ICM, you never need to tighten up just to survive. If you have an edge, play it.
The result: cash game preflop is about positional aggression. The button opens nearly half its hands. UTG folds anything that does not clear a strict quality threshold. The range gap between early and late position is the widest in cash.
GTO open ranges by position in 6-max cash
These are GTO-baseline opening ranges for 100bb effective stacks at a 6-max table. They will need minor adjustments for specific game dynamics (very passive tables loosen slightly, very aggressive tables tighten), but this is the correct starting point.
You act first preflop and worst postflop on every street. Play tight.
AA–77, AKs–AJs, KQs–KJs, QJs, JTs, AKo–AQo, KQo
Small pairs below 77, weak suited aces (A2s–A8s), any offsuit hand below KQo
Two players have folded, but you still face the CO, BTN, and both blinds.
AA–55, AKs–ATs, KQs–KTs, QJs–QTs, JTs, T9s, 98s, AKo–AJo, KQo–KJo
Weak offsuit aces (A2o–A8o), suited gappers below J9s
Only the BTN and blinds remain. One of the most profitable seats at the table.
AA–44, AKs–A7s, KQs–K9s, QJs–Q9s, JTs–J8s, T9s–T8s, 98s–97s, 87s, AKo–ATo, KQo–KTo, QJo
Dominated offsuit hands: A2o–A6o, most two-gappers, 22–33
Last to act on every postflop street. The most profitable seat in cash games.
All pocket pairs, all suited aces, all suited broadway, suited connectors down to 54s, A2o+, most offsuit broadway combos
The true trash: 72o, 83o, 94o — offsuit hands with no equity and no playability
Last preflop, first postflop. Open wide but expect a strong BB defense.
All pocket pairs, suited aces down to A2s, suited connectors to 65s, A2o+, KJo+, QJo
Weak offsuit hands with poor playability OOP: Q4o, J5o, T6o and below
Already invested one big blind. Defend wide — the pot odds demand it.
vs BTN: all pairs, all suited hands, most offsuit broadways, A2o+; tighten vs UTG
Hands that lose money vs. the specific raiser even with the discount — low offsuit trash vs early positions

Preflop open sizing for 6-max cash
Modern 6-max cash games have settled on smaller open sizes than old-school poker. The reasoning: if you size up to 4x, you accomplish two things — you narrow your own range (only premium hands justify the larger risk) and you give opponents a clear signal to fold everything marginal. That hurts you. Small sizing keeps your range wide, applies pressure with less risk, and builds smaller pots when you miss.
UTG / HJ
2.5bb
Standard early position open
CO / BTN
2.2–2.5bb
Slightly smaller as the field shrinks
SB
2.5–3bb
Open larger heads-up vs. one opponent
One important exception: if the table is full of recreational players who call raises without regard to size, size up to 3–4x and build bigger pots with your value hands. GTO sizing assumes opponents play reasonably well. Against bad players, punish them for calling with a larger raise.
3-bet ranges in 6-max cash games
Cash game 3-betting is more linear than tournament play. In a tournament, you often 3-bet polarised — only premium hands and pure bluffs, because your stack is at risk. In cash, you can also 3-bet hands like TT, JJ, AQs, and KQs for value. Your opponents have 100bb to pay you off with worse.
The backbone of a GTO 3-bet range in position (CO or BTN vs. a CO or UTG open):
| Category | Hands | Sizing |
|---|---|---|
| Value (always 3-bet) | AA, KK, QQ, AKs, AKo | 3x in position, 4x out of position |
| Strong value | JJ, TT, AQs, KQs | 3-bet or call depending on position and opener |
| 3-bet bluffs (in position) | A5s, A4s, A3s, KJs, KTs | Same size as value — never smaller |
| Flat calls (in position) | 99–66, AJs, ATs, KQo, QJs–JTs | Call the open, play postflop |
| Fold | Weak suited aces A2s–A3s from OOP, offsuit dominated hands | — |
Out of position from the blinds, GTO leans toward a 3-bet-or-fold strategy vs. positional openers (CO, BTN). Calling out of position is profitable with hands that play well multiway or have strong implied odds, but against aggressive regulars, widening your 3-bet range and folding the rest protects you from being exploited in 3-bet pots while OOP.
Big blind defense in cash games
The big blind is the most misplayed position in cash games. Most players fold too much, throwing away money they have already committed. The math is simple: if the BTN opens to 2.5bb and you are in the BB with 1bb already in, you need 1.5bb to call for a pot of 5.5bb — that is 27% pot odds. You need to win roughly 27% of the time just to break even, and you close the action with position on the SB.
GTO defense frequency vs. common openers at 100bb:
Button (2.2bb)
Call wide — you have the best price and close the action
Cutoff (2.5bb)
Still defend most playable hands
HJ (2.5bb)
Tighten slightly — more hands behind when raised originally
UTG (2.5bb)
Fold more — UTG has a very strong range; you need strong hands too
When you do 3-bet from the BB, use hands that make strong top pair or better (AQs, KQs, AJs) and blockers that reduce your opponent’s strong range (A5s, A4s). The classic BB 3-bet mistake is doing it with hands like QTs or JTs — they have poor equity when called by the range that continues.
Adjusting for stack depth
The 100bb ranges above assume both players are fully stacked. Stack depth changes things significantly:
100bb (standard)
Play the full GTO ranges as listed. Suited connectors and small pairs have maximum implied odds.
50–70bb (short buy-in)
Reduce suited connector and small pair play by 30–40%. With less behind, you cannot extract enough postflop to justify the preflop investment. Strengthen your range with hands that play well in single-raised pots — broadways and big pairs.
25–40bb
Switch to a raise-or-fold framework. The stack-to-pot ratio is too small to profitably peel speculative hands. Open with top 20% hands from any position, 3-bet jam over opens, and fold otherwise.
15bb and below
Pure push-fold territory. Reference GTO push/fold charts for your specific position and hand. Every open becomes an all-in or a fold.

Why speculative hands are better in cash games
The defining feature of cash game preflop strategy is implied odds. When you call a raise with 55 or 76s, you are not expecting to win at showdown with top pair — you are planning to stack your opponent when you hit a set or a flush on the right board. Those payouts only happen when your opponent has 100bb in front of them and is willing to commit.
The rule of thumb for set mining: you need roughly 15:1 implied odds to profitably call with a pocket pair (investing 1bb for every 15bb you expect to win when you hit). Against a 2.5bb open at 100bb effective stacks, you are paying 2.5bb to potentially win 100bb — a 40:1 ratio, well above the threshold. Against a 3bb open at 30bb effective, you are paying 3bb to potentially win 30bb — 10:1, not profitable.
Suited connectors follow similar logic. They flop strong draws or strong pairs at a high enough rate that the implied odds justify the preflop call — but only when you are in position or in the BB with a discount, and only when effective stacks are deep enough to pay off the made hands.
The three most expensive cash game preflop mistakes
Playing too many hands from early position
UTG opening 22+, suited aces, and offsuit broadways is a leak that compounds across thousands of hands. Every marginal open from UTG means you are entering pots out of position with medium-strength hands. The solution is not just folding — it is understanding WHY UTG requires a strong range and drilling those exact hands until you fold the marginals automatically.
Over-folding the big blind
Folding 75o to a BTN open feels disciplined but is mathematically wrong at 100bb. You need to defend roughly 50% of hands from the BB vs. a button open. Players who consistently fold too much from the BB give regulars a blank check to steal with any two cards. The fix is to widen your BB defense range and accept that some of these hands will be marginal — that is the price of the discount.
Limping from any position other than the SB
An open limp abandons the initiative, gives the BB a free play, and signals weakness to everyone at the table. GTO poker does not open-limp from UTG, HJ, CO, or BTN. The SB is the one exception — limping your entire SB range vs. a passive BB is a valid GTO strategy. Everywhere else, raise or fold.
How to study cash game preflop ranges
Reading about ranges and playing with them are different skills. The most efficient path to internalizing GTO cash game ranges is repetition with feedback — not videos, not books, not forum posts.
Pick your biggest leak position
If you are not sure, start with UTG. It is the most constrained position and the one where mistakes compound fastest. If you already play UTG tightly, move to BB defense.

FAQ
How tight should I play UTG in 6-max cash games?
Open 14–16% from UTG: pocket pairs 77+, suited broadways down to JTs, AJs+, AQo+, KQo. Fold small pairs below 77 and weak suited aces. You have five players left to act and you will be out of position on every postflop street.
What open size should I use in a 6-max cash game?
Standard is 2.5bb from UTG/HJ, 2.2–2.5bb from CO, and 2.2bb from the BTN. From the SB you can open 2.5–3bb since you only have the BB to beat. Avoid sizing up too much — it narrows your range and makes you easier to exploit.
Is 6-max cash harder than full ring?
It depends on your style. 6-max plays with more aggression and wider ranges, so there is more pressure to understand 3-bet/4-bet dynamics and positional play. Full ring rewards tighter, more straightforward preflop decisions. Most online cash games today are 6-max.
When should I 3-bet vs. call in cash games?
3-bet value hands (QQ+, AK) from any position. Add bluffs with good blockers and playability from position: A5s, A4s, KQs on the BTN or CO. From out of position (blinds), 3-bet or fold vs. aggressive players rather than calling. Cold calling in position with hands like TT, 99, AJs is correct too.
How does stack depth affect preflop ranges?
At 100bb (standard), play normally. At 50–70bb, reduce suited connector and small pair play — their implied odds shrink. At 30bb or less, shift toward a raise-or-fold strategy: limp equity disappears and preflop edges get larger relative to the pot. GTO push/fold charts take over at 15bb and below.
Should I ever limp in 6-max cash games?
Almost never from any position other than the SB. An open-limp forfeits initiative and gives the big blind a free defense. The one exception GTO allows is a SB limp vs. a passive big blind — you can limp your very wide SB range and see flops cheaply. Everywhere else, it is raise or fold.
What is the best way to practice cash game preflop ranges?
Drill GTO range quizzes by position until the decisions are automatic. Preflop Wizard lets you practice each spot — UTG through BB — with AI feedback on whether your open, fold, or 3-bet was correct. Fifteen minutes per session on your specific leaks beats hours of watching videos.
