Check Raise Quiz Answers & Explanations
Here are the questions, answers and explanations from our 'Can You Ace This Check Raise?' quiz.
1. 20bb stacks, MTT with BB ante. EP opens to 2bb and you defend in the BB. The flop comes Q♠ 8♠ 2♦. You check and EP bets 30% pot. Which of these hands should you check raise?
The lower the SPR, the more you want to slow play your best hands. That means two pair+ (Q8o and 22 in this example) should just be called. K♣Q♣ is a strong, but vulnerable hand right now and should be raised for value and protection. A♠J♠ has an incredible amount of equity and works better as a call, since that equity reduces if you raise and your opponent calls. You have weaker flush draws, like A♠9♠ or K♠4♠, to check raise as a bluff, and these work better since they can get more of the EP’s better hands to fold as well.
2. Fill in the blank - when facing a small cbet size I should check raise _______ than when I face a big cbet size.
The smaller the cbet size, the more frequently you want to check raise. When your opponent bets big they are generally more polarised and it therefore makes sense to just call so that they can continue bluffing and lose less against their value range.
3. 60bb stacks, MTT with BB ante. BTN opens to 2.3bb and you defend in the Big Blind. You check and the BTN cbets 30% pot. Which board should you check raise most often?
9♠ 9♦ 3♣
K♠ Q♠ 6♠
K♦ 7♠ 6♠
993r is a board that the BTN should cbet very frequently for a small size and also a board that the BB should check raise very aggressively, around 30% of the time. This range will include boats, trips, underpairs, 2nd pairs, 3rd pairs, Ace highs like A♣8♣, King highs like K♠4♠ and seemingly nothing hands like 75s with a backdoor flushdraw and QJs as well. You can see in the image below just how aggressively you should be check raising.
KQ6 mono is only check raised around 6% of the time and K76fd is check raised around 15%. Interestingly, the BTN should check back on KQ6 mono almost 50% of the time and around 35% on K76fd. Many players will cbet these boards too frequently, which means there is an opportunity to adjust your check raising strategy as an exploit.
4. 40bb stacks, MTT with BB ante. HJ opens to 2.3bb and you call in the BB with T♠9♠. The flop comes Q♠ J♦ 2♠ and you check. The BTN bets 70% pot. What should you do?
You have a number of combo draws here (A♠T♠, K♠T♠, K♠9♠, T♠9♠, T♠8♠ and 9♠8♠) to choose from. T♠9♠ works better as a check raise than A♠T♠ since you can get more of the HJ’s better hands to fold. For example, you can get a lot of A3-A9 hands to fold, which is much better when holding T♠9♠ than A♠T♠. You also have a whopping 40.3% equity versus the HJ’s best hand (QQ). Matthew Janda talks about two reasons to bet in his book, No Limit Holdem for Advanced Players – to deny equity and to build a bigger pot for the times you win. Raising here satisfies both of those criteria.
5. 30bb stacks, MTT with BB ante. The CO opens to 2bb and you call in the BB with J♥9♥. The flop comes A♠ K♦ 9♠, you check and the CO bets 70% pot. What should you do?
This is a great board for the CO as he has almost 70% equity so this is a classic spot where you have to fold, even though you've hit a piece of the board. If the CO had bet 30% pot instead, it's still not a great call with J♥9♥. Versus the 70% sizing you can call with J♦9♦ (bottom pair with a backdoor flush draw and a backdoor straight draw), but J♥9♥ and J♣9♣ are just too weak to continue versus the CO's far superior range.
6. 40bb stacks, MTT with BB ante. MP opens to 2.3bb and you call in the BB. The flop comes K♠ Q♠ 6♠, you check and the BTN bets 30% pot. Which of these hands should you raise most frequently?
The solver will often take very weak bottom pair hands and turn them into bluffs in this situation. 62s-65s are all high frequency check raises in this spot. Given that it’s a flop that MP should be betting very frequently for a small sizing, you can get a lot of better hands to fold when you raise. You also block bottom set, which MP won’t fold to the check raise.
7. 30bb stacks, MTT with BB ante. You open for 2bb from EP with A♥9♥ and the CO 3-bets to 6bb. It folds back to you and you make the call. The flop comes 9♠ 7♦ 2♠, you check and the CO bets 20% pot. What should you do?
Your hand is strong and vulnerable right now and benefits from protection to deny equity. You should raise or jam your best 9x in this spot together with TT and some overcard+flush draw type hands like K♠T♠ too. Jamming feels counter-intuitive because you will often be dominated by overpairs when called, but you do generate fold equity and can get it in versus worse. Think about what he does with J♣9♣ or K♠T♠, for example.
8. 30bb stacks, MTT with BB ante. The BTN opens to 2bb and you call in the BB. The flop comes K♣ 8♠ 2♦, you check and the BTN minbets. Which of these hands should you NOT check raise?
T♥7♥ doesn’t have a back door flush draw and actually blocks the hands you are targeting to fold. You can generate more fold equity on the flop by raising hands with backdoor draws because they will block the BTN’s continues. For example, the BTN should continue with A♠7♠, A♦7♦ and A♣7♣, but should fold A♥7♥. You can also improve on more turn cards since you can pick up a flush draw, which you can continue to play aggressively.
9. 30bb stacks, MTT with BB ante. The BTN opens to 2bb and you call in the BB. The flop comes 8♣ 7♦ 4♠, you check and the BTN bets 70% pot. Which of these hands should you check jam?
JTs has the lowest equity and again benefits from getting more of the BTN's better hands to fold. You can get lots of Ace highs, King highs and Queen highs to fold when you jam. 96s works better as a call as your equity is higher.
10. 60bb stacks, MTT with BB ante. The BTN opens to 2.3bb and you call in the BB. The flop comes 6♣ 3♦ 2♠, you check and the BTN bets 110% pot. Which of these hands should you raise most frequently?
77 benefits the most from raising for value and protection. If you 3-bet all better pairs (88+) preflop, then 77 is your strongest, and most vulnerable, overpair. It’s similar in value to A6, which should also be raised at a high frequency. When your opponent chooses a bigger sizing it means they are more polarised to value hands and bluffs. This shouldn't discourage you from protecting your most vulnerable value hands. Sets, two pairs and straights are strong enough on this board where they don't need any protection.
