Opening Ranges Quiz Answers & Explanations

Here are the questions, answers and explanations from our 'How Well Do You Know Your Opening Ranges' quiz.

1. It’s the start of the tournament, you have 100bb and the blinds are 100/200 with a 200 big blind ante. Roughly what percentage of hands should you open from the Button at a tough table?


15%

22%

28%

36%

54%


At a tough table you might think that you should look to tighten up your range, but as you’re on the Button in this example, you have position on your tough opponents. If you were playing versus weaker opponents in the blinds you could actually open much wider than 54% because they won’t defend wide enough or they won’t 3-bet wide enough, or both!

2. True or false – you should never limp in tournaments.


True

False

Gone are the days when limping was seen as weak and a massive no-no for professional poker players. There are now situations when developing a limping range, especially in late position and with shorter stacks, is the way to go. The solvers are showing us that limping at final tables is also something we want to start working into our game.

3. Fill in the blank: You should open raise to a ________ size as your stack gets shorter.


Smaller

Bigger

As your stack gets shorter you want to risk less preflop. As you dip under 25bb, making a 2.5bb raise risks more than you need to. It’s also worth thinking about short stacks left to act after you raise – with a few sub-20bb stacks behind, you should consider raising smaller too, risking only what is necessary.

4. Which of these situations warrants the loosest preflop raising ranges?


Tournament, 60bb deep, with antes, on the Button

Tournament, 60bb deep, without antes, on the Button

Tournament, 25bb deep, with antes, on the Button

Tournament, 25bb deep, without antes, on the Button


With more money out there to win, we should be opening more hands with antes. At 25bb, either of the blinds can jam on us, which means that we can't go too crazy with our opening ranges. At 60bb, that's less likely to happen, which means we can open the widest in this situation.

5. True or false – you should fold ATo off 20bb from UTG, 8-handed.


True

False

ATo is a good opening hand from UTG, 8-handed off 20bb. It blocks very strong hands that will 3b or jam like AK,AQ, TT and AA, and you still have good equity versus flatting ranges. You should probably fold A9o though.

6. Tournament, 60bb deep, with antes, at an aggressive table - what’s the worst suited connector you should open from UTG, 8-handed at full frequency?


76s

87s

98s

T9s

While you can open all suited connectors at a soft table, T9s is the only hand you should open at full frequency at a tough one.

7. Tournament, 100bb deep, with a big blind ante. You are in the Small Blind versus an aggressive Big Blind – which action should you take most frequently?


Limp

Raise to 3.5bb


When it folds to us in the Small Blind, we are getting a good price to limp and try to see a cheap flop. We don't have too many hands that we want to play for stacks at 100bb, so many of our hands want to go for a limp/call. Many weaker players won't isolate SB limps wide enough so you can get away with limping even more than GTO preflop solutions suggest, too!

8. Tournament, 40bb deep, with antes, at a tough table, roughly what percentage of hands should you open from the Cut Off?


19%

25%

30%

38%

51%

You should open about 38% of hands from the Cut Off at a tough table, potentially opening wider at a weak one because your opponents probably won’t call or 3-bet wide enough.

9. True or false – the only options available to you when you have 10bb are shove or fold?


True

False

There are some situations when limping is a higher EV line than shoving with 10bb. For example, it folds to you in the Small Blind with AA. It’s much better to limp/call or have an opportunity to play postflop versus a weak check back range than it is to jam. Sure, jamming is profitable, but it’s not as profitable as limping. You can also make this play with 88 or QJs.

10. Tournament, 15bb deep, with antes, you're on the Button - what’s the best hand you should jam?


AA

AKo

ATs

KK

AKo is the only hand in GTO preflop solutions that favours jamming. The other three hands prefer either limping or minraising. AA, KK and ATs are strong enough to induce and have great postflop playability.
