Poker Preflop Quiz: 10 GTO Spots to Test Your Range (2026)
Most players think they know their preflop ranges. Most are wrong by 10-15% on the borderline spots. This quiz covers 10 real preflop decisions — UTG opening range, big blind defense, squeeze plays, 3-bet spots, and a tournament push/fold decision — with GTO-accurate answers and explanations for each.
Quick Answer
The 10 spots in this quiz cover the most common preflop decision types: UTG opening range (tighter than most players think), BTN opening range (wider than most players think), big blind defense frequencies, 3-bet spots in and out of position, squeeze opportunities, and a short-stack MTT push/fold decision. Work through each scenario before reading the answer. Average recreational player: 5-6 correct. Solid regular: 8+. Perfect score means you have internalized GTO preflop fundamentals.
What this quiz covers
Preflop mistakes fall into two categories: playing too many hands in spots where the range should be tight (UTG, facing 3-bets), and playing too few hands where the range should be wide (BTN opens, BB defense). Both are expensive. A player who folds KTo from UTG is fine; a player who folds T7s from the button is bleeding EV every orbit.
The quiz is structured across three skill layers:
| Spots | Skill area | Most common mistake |
|---|---|---|
| 1-3 | Open ranges and BB defense | Playing too many hands from EP, not defending BB wide enough |
| 4-6 | 3-bet and squeeze spots | Calling OOP where 3-betting is better; missing squeeze opportunities |
| 7-8 | Polarized 3-bet construction | 3-betting only value hands; not understanding blocker-based semi-bluffs |
| 9-10 | MTT push/fold and mixed strategies | Over-folding short stacks; treating mixed spots as binary |
All spots assume a standard 6-max cash game at 100bb unless stated otherwise. The GTO answers come from solver outputs at these parameters. For the full opening range reference, see the GTO preflop charts by position.
UTG open with KTo at 6-max (100bb)
6-max cash game, 100bb deep. You are UTG (first to act). The action folds to you. You hold K♠ T♦. Do you open-raise or fold?
GTO Answer: Fold
KTo is not in the standard UTG opening range at 6-max 100bb. UTG opens around 18% of hands — a tight range of strong pairs, suited broadways, and high-equity suited hands. KTo is an offsuit hand that plays poorly out of position against 3-bets and gets dominated too often by the stronger Kx and Tx hands in opponents' continuing ranges. The suited version (KTs) is a different story: KTs is a standard UTG open. The offsuit version bleeds chips in the long run from early position.
Verdict: Correct play: Fold. Open KTs from UTG, fold KTo.
BTN open with T7s at 6-max (100bb)
6-max cash game, 100bb deep. Action folds to you on the button. You hold T♣ 7♣. Do you open-raise or fold?
GTO Answer: Open-raise
The button opens around 43-45% of hands at 6-max 100bb — one of the widest ranges in poker. T7s is a solid member of that range. It has flush draw potential, two-pair and straight possibilities, and plays well in position against the blinds. The BTN opens virtually all suited connectors down to 54s (and sometimes lower), so T7s is not even close to the borderline. Players who fold T7s on the button are leaving significant EV on the table.
Verdict: Correct play: Open-raise (2.5bb is standard).
BB defense with 87s facing a UTG raise (100bb)
6-max cash game, 100bb deep. UTG raises to 3bb. Action folds around to you in the big blind. You hold 8♥ 7♥. Do you call or fold?
GTO Answer: Call
The big blind defends around 32-38% of hands against a UTG raise. 87s sits comfortably inside that range. Suited connectors are among the strongest hands to defend from the big blind: they have high implied odds (flopping straights and flushes), they do not get dominated by UTG's strong range the way offsuit broadway hands do, and they realize their equity well multiway. You are getting roughly 3.5:1 on a call here, and 87s has enough equity and playability to make defending correct. This is not a 3-bet hand against a tight UTG range — it is a call.
Verdict: Correct play: Call. 87s is a standard BB defend vs UTG.
3-bet or call JJ from BB vs BTN open (100bb)
6-max cash game, 100bb deep. The button opens to 2.5bb. SB folds. You hold J♦ J♣ in the big blind. Do you 3-bet or call?
GTO Answer: 3-bet
JJ from the big blind versus a button open is a clear 3-bet for most solvers. The button opens ~43-45% of hands, so JJ is well ahead of the average hand in that range. The main reason to 3-bet rather than call: you will be out of position for the entire hand, and calling lets the button see a cheap flop with a wide range and play poker in position against you. A 3-bet to around 9-10bb takes the lead, narrows the BTN's range, and lets you play with initiative. You will face a 4-bet occasionally — that is fine, you can call the 4-bet with JJ at 100bb.
Verdict: Correct play: 3-bet to ~9-10bb.
3-bet or call AQo from SB vs BTN open (100bb)
6-max cash game, 100bb deep. The button opens to 2.5bb. You are in the small blind with A♥ Q♦. Do you 3-bet, call, or fold?
GTO Answer: 3-bet
AQo from the small blind versus a button open is one of the cleaner 3-bet spots in the game. Calling is wrong: you would be out of position with a hand strong enough to take the lead. Folding is obviously wrong. AQo crushes the BTN's wide opening range, it blocks AA and AK, and 3-betting makes you the aggressor with a hand that plays well when called. The SB's 3-bet range versus the button is not polarized the same way it is versus early position — AQo is a pure value 3-bet here, not a bluff.
Verdict: Correct play: 3-bet to ~8-9bb.

Squeeze with AJs from BB (BTN opens, CO calls) (100bb)
6-max cash game, 100bb deep. The button opens to 2.5bb. The cutoff cold-calls. Action folds to you in the big blind with A♠ J♠. Do you squeeze (3-bet), call, or fold?
GTO Answer: Squeeze
This is a strong squeeze spot. When a cold-caller enters the pot, three things happen: there is more dead money in the middle, the BTN's range is somewhat capped (the BTN would have re-raised with the very strongest hands), and the cold-caller's range is capped even more (no 4-bet is likely coming). AJs squeezes well here for two reasons: the ace blocker reduces the chance either player holds AA or AK, and the suited nut-flush potential gives you outs when called. Squeezing to around 10-11bb is standard. See more on squeeze spots in the poker squeeze play guide.
Verdict: Correct play: Squeeze to ~10-11bb.
BTN 3-bet with A5s vs HJ open (100bb)
6-max cash game, 100bb deep. The hijack opens to 2.5bb. Action folds to you on the button. You hold A♣ 5♣. Do you 3-bet, call, or fold?
GTO Answer: 3-bet (lean)
A5s from the button facing an HJ open is a mixed-strategy spot, but most solvers favor 3-betting. The key properties of A5s that make it a strong 3-bet: it blocks the aces in the HJ's 4-bet range (AA, AK, AQ), it has nut flush draw potential, and it can make the wheel straight. When you 3-bet A5s as a semi-bluff, you benefit from fold equity and retain good equity when called. A5s plays worse as a flat call: you take a speculative hand OOP with a weak top pair and an ace that often makes your opponent fold the second pair. The 3-bet is the preferred line. Review the full 3-bet strategy guide for more on polarized ranges.
Verdict: Correct play: 3-bet (primarily). Calling is also fine.
BB defense with Q6s vs CO open (100bb)
6-max cash game, 100bb deep. The cutoff opens to 2.5bb. SB folds. You hold Q♥ 6♥ in the big blind. Do you call or fold?
GTO Answer: Call
The big blind defends around 40-44% versus a CO open at 100bb. Q6s sits inside that range. The CO is a middle-late position opener with a range of around 28-30% — wider than UTG, but still semi-tight. Q6s has queen-pair potential, flush draw equity, and decent implied odds when flopping a flush draw or two pair. Getting ~3:1 pot odds plus the 1bb already in the pot, calling Q6s is correct. Folding would be too tight and give the CO too much fold equity. See the full big blind defense guide for detailed defense frequencies.
Verdict: Correct play: Call.
MTT 12bb SB: shove or fold with A7o?
MTT, on the money bubble. You are in the small blind with 12 big blinds. The action folds to you. You hold A♣ 7♦. The big blind has you covered. Do you shove all-in or fold?
GTO Answer: Shove
A7o from the SB at 12bb is a clear shove in any GTO push/fold chart. At this stack depth, your options are shove or fold — there is no room for a standard open-raise. A7o has an ace blocker (reducing the chance the BB holds a strong calling hand), decent raw equity against the BB's calling range, and significant fold equity since the BB has ICM pressure to fold marginal hands on the bubble. Even accounting for ICM pressure, A7o generates positive ICM EV from the SB at 12bb. Players who fold A7o here are making a significant mistake — they are letting their stack blind down to a point where they have no fold equity at all. See the short stack push/fold guide for full shove ranges by stack depth.
Verdict: Correct play: Shove all-in.
3-bet or call ATs from BTN vs HJ open (100bb)
6-max cash game, 100bb deep. The hijack opens to 2.5bb. The cutoff folds. You are on the button with A♦ T♦. Do you 3-bet, call, or fold?
GTO Answer: Mixed (3-bet or call)
ATs on the button versus an HJ open is a genuine mixed-strategy spot where both 3-betting and calling are correct — the solver splits between them. 3-betting works because: ATs blocks the HJ's 4-bet range (ace blocker), it has nut flush potential, and taking the lead in position with a strong hand is generally good. Calling also works because: ATs plays extremely well in position postflop, you avoid giving away range information, and you keep the HJ's range wider (they keep hands they would fold to a 3-bet). If you had to pick one line, 3-betting has a slight edge for most player pools where opponents over-fold to 3-bets. But this is one of the spots where the exact action matters less than the reasoning behind it.
Verdict: Correct play: Mix of 3-bet and call. Both are profitable.
How to interpret your score
Be honest with yourself: count a spot correct only if you got both the action AND a rough understanding of why before reading the answer.
0-4 correct
Fundamentals neededThe main gaps are likely range widths — playing too tight from late position and too loose from early position. Study the opening ranges by position before working on more complex spots.
5-7 correct
Solid foundation, edges to fixYou have the basics right but are probably missing the squeeze and polarized 3-bet spots. These are the highest-EV corrections for mid-stakes players. Review 3-bet construction and blocker theory.
8-9 correct
Strong GTO fundamentalsYou understand preflop GTO well. The spots you got wrong are probably the genuine mixed-strategy hands where both lines are correct. The next step is drilling these spots at speed so they become automatic.
10 correct
Internalized rangesYou have GTO preflop fundamentals locked in. Your edge now comes from speed and execution under pressure — getting these right in-game when distracted or tired. The app drills you on that.
The 3 preflop leaks this quiz exposes
After drilling thousands of players through these spots, the same errors cluster. Fix these three and you will see an immediate improvement in your win rate.
Playing too loose from UTG and too tight from the BTN
Spot 1 (KTo UTG fold) and Spot 2 (T7s BTN open) catch this in opposite directions. The asymmetry is large: opening KTo from UTG loses roughly 5-8bb/100 in the long run. Folding T7s from the button loses a similar amount. Both mistakes feel intuitive — KT looks like a good hand, T7 looks weak. Solvers do not care about hand appearance; they care about equity and position.
Calling OOP where 3-betting is correct
Spots 4 and 5 (JJ from BB, AQo from SB) catch players who flat-call out of position with strong hands. The reason this leaks EV: calling OOP with a strong hand lets the aggressor see a flop with their full wide range, in position. A 3-bet narrows their range and gives you the lead. AQo from the SB especially: you cannot call profitably OOP against a 43% BTN range with a hand that will be dominated by many flop textures.
Missing squeeze spots and blocker-based 3-bets
Spots 6 and 7 (AJs squeeze, A5s 3-bet) catch players with a polarized 3-bet mental model: you only 3-bet your best hands and fold everything else. GTO 3-bet ranges are balanced — strong value hands plus semi-bluffs with blockers. A5s and AJs 3-bet because of their ace (blocks AA, AK, AQ) plus real equity when called. Players who never 3-bet with A5s are 3-betting an unbalanced range opponents can exploit. Review the 3-bet strategy guide for full range breakdowns.
How to practice these spots until they are automatic
Reading the answers once is not enough. Preflop decisions need to be automatic at the table — you should not be calculating KTo UTG while also watching your opponent’s timing tells and managing your stack. The answer needs to be instant.
The most efficient way to build that speed is spaced repetition on real spots. Static charts help you memorize ranges, but they do not train you to make fast decisions under pressure. You need to see the hand, the position, the stack depth — and fire back the correct action without thinking.
That is exactly what the best preflop range training methods focus on. The short version:
Drill positions in isolation
Do not try to learn all positions at once. Master BTN and BB first (highest frequency, biggest impact), then add CO and SB, then early position.
Use active recall, not passive review
Cover the answer, make your decision, then check. Reading charts passively builds familiarity without building the fast pattern recognition you need in-game.
Add time pressure gradually
Start with unlimited time. Once you are hitting 85%+ accuracy, cut your decision time to 10 seconds. Then 5 seconds. The goal is instant recall, not careful calculation.
Focus on mistakes, not total spots reviewed
Review the spots you got wrong three times before moving on. Drilling spots you already know is satisfying but wasteful.

Frequently asked questions
How accurate are GTO preflop ranges in real games?
Very accurate at stakes above $0.25/$0.50 online and $1/$2 live. The main deviation is that real opponents play worse than a GTO opponent, so you can exploit them by deviating from GTO — but you need to know GTO first to know where and how to deviate. Against unknown opponents, GTO is always the safe baseline.
Should I memorize exact preflop ranges?
You do not need exact hand-by-hand memorization. You need internalized range shapes: UTG opens tight (around 18%), BTN opens wide (around 44%), BB defends wider than most people expect (around 35-40% vs BTG, 32-38% vs UTG). Once you have the shapes, the borderline hands become easier to reason through. The quiz spots above are deliberately on the edges of those ranges.
What is the difference between a GTO preflop quiz and a poker hand history review?
Hand history review covers specific hands from your sessions — including postflop decisions, bet sizing, and reads. A preflop quiz isolates preflop decision-making in a format you can drill repeatedly without needing hands to review. Both are valuable; preflop drilling is more efficient for building range knowledge because you can repeat 50 spots in 10 minutes.
How many spots should I drill per day to improve?
Twenty to thirty focused spots per day is enough to see improvement within two to three weeks. The emphasis is on focused: make an actual decision before seeing the answer, and review every mistake carefully. Passively clicking through spots with no real decision made gives you the feeling of practice without the retention.
Do these quiz spots apply to 9-max poker as well?
Mostly yes, with adjustments. 9-max tightens early-position ranges (UTG in 9-max is even tighter than 6-max UTG because there are more players behind). BTN and BB adjustments are similar. The MTT push/fold spot (Spot 9) applies to both formats. If you are playing full ring, check the dedicated 9-max preflop chart guide for the specific differences.
