Navigating Range Disadvantage as the 3-Bettor

Picture this: We’re playing a NL500 6-max cash game, and we’ve won a few pots, now sitting 150bb deep. We look down at the beautiful K♣Q♣ in the BB, a suited match of royalty. The CO raises. It folds to us and we comfortably 3-bet to 12bb. Our opponent responds by flat-calling our 3-bet, and we take a flop.

What now? Don’t panic. Let’s consult the Wizard!

Board / Range Interaction

Intuitively, most of us know that flops below Ten-high help the defender, not the aggressor. Since they passed up on the chance to 4-bet us preflop, big card flops will be good for us, and medium flops—which our 3-betting range won’t contain much of—will be bad for us.

Aggregate Flop Reports are an excellent tool for viewing EV on flops classified by various factors, such as suitedness, connectedness or in this case high card. In this example, I’ve sorted the flops based on BB’s EV from low to high. It’s clear that King-high flops are the best for our range, whereas Five to Nine-high flops are the worst.

When there aren’t any broadwayBroadway
A ten through ace straight. “Broadway cards” can also be used to describe any 10, J, Q, K, or A card. cards, hands like AK—which the 3-bettor would always have more of compared to the caller—have missed. In addition, our CO opponent is helped by the flop, improving a lot of their calling hands.

They have 3 sets at a higher frequency, middling pocket pairs 77–66, and the suited connectors like 87s picked up pair and draw equity; they even flopped a straight with 76s much more often than us.

The ‘Ranges’ view is excellent for providing insight at a glance into which hands appear more frequently in either player’s range. In this example, OOP has a far higher proportion of KK+ and AK, but IP has a much higher frequency of middling pocket pairs and suited connectors. Suited broadways like AQs and JTs are found equally in both ranges.

Overall, in terms of board/range interaction, 8♥5♦4♠ is a board that interacts very well with our opponent’s range and not at all well with ours. In fact, our overall equity and EV are lower than those of the CO defender on this board.

The CO also retains a greater percentage of ‘nut’ hands – in this case: sets, straights and occasionally bottom two pair 54s.

By breaking the ranges down into equity buckets, we get a clearer view of this situation. The CO has the highest percentage of ‘nut’ hands with at least 90% equity, which are 88, 55, 44, and 76s. The BB retains the lead for hands with 70-90% equity, mainly QQ–AA and 54s. Therefore, BB’s overpair value region still allows us to play with a polarizedPolarized

Yet, we can’t check-fold everything that missed. Let’s take a closer look at how we should proceed on the flop by contrasting with another flop.

Betting / Checking Frequency

Usually, as the 3-bettor on a flop like KJ3r, we have a large incentive to be polarized with our overpair nut advantage. That means our value hands want to be betting often, using a geometric size derived from the stack-to-pot ratio (SPR)Stack-to-pot ratio (SPR)
The effective stack divided by the size of the pot. SPR is commonly used to gauge the value of implied odds and the relative value of made hands. that can get us all-in by the river. On a KJ3 board where we have a clear nut and equity advantage over our opponent, we can thus get away with betting our entire range, even out of position.

On the previous 854r flop, however, we lost both our nut advantage and equity advantage as the BB. Therefore, we had to check more often.

This comparison is clear when we compare 854r to a flop like KJ3r, where we do zero checking as the 3-bettor.

Continuation Betting The Flop

OK, let’s look at what hands we should consider continuation betting. First off, GTO Wizard tells us that we should begin splitting our range between bets and checks on the flop. That means no range betting.

We should be checking roughly 64% of the time, and when we do bet, we prefer a larger size of 75% pot. This makes sense because 150bb deep, we need to start betting a bit bigger on the flop already to set up an all-in by the river with our value hands. A common rookie mistake is to think that as the PFR with a preflop range advantage in overpairs and AK, we can blindly c-bet for half pot with our entire range on any flop — the data shows that this is far from the case.

The second point that we should observe is how we treat our suited hands differently. In this example, we will examine our case study hand, K♣Q♣.

Of all our suited hands, only three-quarters have backdoor flush draws. The one that doesn’t, which in this situation is clubs, should be handled with much less aggression. In the graphic above, we can see that our betting frequency is dramatically reduced when we compare K♦Q♦ to the K♣Q♣. One reason is that KQ of clubs cannot make a nutted backdoor flush, but another reason that’s often missed is that it’s also a hand that blocks hands we want our opponent to have.

K♣Q♣ has a trash removal score of 8. If our opponent has Q♣J♣ or K♣T♣, for example, they won’t continue in the hand when we c-bet. A high trash removal score means we block a lot of trash in our opponent’s range. This isn’t good when we are ‘bluffing’ since we want our opponent to have trash that folds.

The third point might be one regarding offsuit hands.

Should we then only be barreling non-made hands that have backdoor flush draws?

Indeed, we are checking and folding to a bet every time with KQo. However, a hand like Q♠J♠ makes an excellent bluff with its backdoor straight and flush possibilities.

Let’s examine the Equity Distribution Chart on 854r:

Let’s now look at our value hands. Although there’s a lot of mixing, it seems like JJ is the threshold where we have enough of an equity gap that we definitely prefer betting. There are quite a few middling hands (e.g., 86s, A8s, and 77) employ a very mixed strategy so we might opt to split betting and checking with these hands at a 50-50 rate.

In terms of betting for value, we could consider a hand like JJ, along with some draw+pair equity hands such as 86s that can improve later.

A hand like QQ particularly wants to bet as it’s a high equity hand, but many turn cards make the board worse for this hand — overcards / straight-completing cards come to mind.

Checking The Flop

Recall that this is a flop where the 3-bettor has lost the nut and equity advantages, but we still retain the ‘good hands’‘good hands’

edge with our overpairs.

As such, our flop c-betting frequency will be low, but it’s also necessary to protect our checks with a strong check-calling and check-raising range. Otherwise, our opponent will be able to attack our checks freely.

When the BB checks, the CO will stab about 60% of the time and will only use a small size – either the 20% or 33% pot sizing.

Why does the CO only use a small size to stab when facing a check?

The main reason I would offer for this bet size is that this is the best risk-reward ratio to make a hand as strong as AQo or KTs fold, and even the 3-bettor’s favorite hand, AKo, becomes almost indifferent to folding. A lot of BB’s hands will have to fold here without CO needing to risk a big bet despite CO having the nut advantage. Yet, it’s important for CO to bet so that these hands don’t get to realize equity for free.

Against the 20% pot bet, BB responds by check-raising 22% of the time, calling 52%, and folding 25% of the time.

Against the 33% pot bet, BB responds by check-raising 25% of the time, calling 36%, and folding 38% of the time. The smaller the bet we face, the better pot odds we have to continue. Thus, we can continue with more hands vs a smaller bet.

Filtering by suit presents a very clear strategic big picture. Here, I’ve filtered BB’s range to include only clubs. Facing a bet, BB folds everything that doesn’t have a direct link to the board. KTs folds, but we continue with K6s.

For brevity’s sake, I’ll briefly summarize BB’s flop strategy after checking and facing a small stab by CO:

Our main takeaways are as follows:

Thanks for reading this article! I hope you’ve learned some takeaways that you can incorporate into your game. Flop strategy is broad and complex, and there’s often a lot of mixing, so it’s important to understand your strategy from a broader perspective. In this study, understanding how to construct our flop c-bet strategy and knowing that K♠Q♠ and K♣6♣ are both better bluffs than K♣Q♣ clubs are key learning points that can be applied to many other similar situations.
