How to Play the Turn After Range Checking the Flop (Part 1)
Some time ago, I wrote about a few spots where checking your entire range on the flop is the right play. In this series, we’ll take it a step further and explore how to approach the turn after checking the flop.
To understand these spots fully, we’ll break down the technical aspects in detail. By going through each scenario one at a time, you’ll gain the tools to make sharper decisions and extract more value from these situations moving forward.
Let’s dive in.
Out of Position as the Preflop Raiser (Against the Button, Cutoff, or Middle Position) on Low Connected Boards
Let’s go back to the example from the previous article: the flop comes 6c 4s 3c, and we’ve open-raised from the Cutoff. The Button cold-calls.
After we check our entire range, the Button should respond by betting his entire range with a small sizing. This is because he holds a significant range and nut advantage on this type of board.
Since we checked everything on the flop, it stands to reason that we’ll also be mixing in aggressive check-raises (around 15% of the time) because we still retain all our strongest hands. That said, this article won’t focus on the check-raise strategy. Instead, we’ll concentrate on the most common line we’ll be taking: check-calling, which happens roughly 47% of the time.
There are three main types of turns:
- Four-straight completing cards
- Flush completing cards
- Overcard Broadway
In the first part of this series, we’ll break down how to navigate the turn when it completes a four-straight. These turns can drastically shift the dynamic, especially when you’ve checked the flop and are out of position.
Let’s keep going.
Four-straight Completing Turn
Let’s say the 5d comes on the turn. This card completes the four-straight and doesn’t change our position—we’re still at a nut disadvantage, so we should continue checking our entire range.
After we check, the Button will maintain a highly aggressive strategy, often firing a 75% pot bet. That’s because a large portion of his range still wants to value-bet or apply pressure.
Here’s a quick look at what the solver recommends at equilibrium:
Let me break down what we’re looking at here.
In the upper-right corner, you’ll see that the solver elects to check-fold with 44.19% of the range; that’s represented by the blue-colored rectangle. Given that the Button is betting 75% pot, this folding frequency lands us very close to the minimum defense frequency (MDF), which is approximately 43%.
The solver opts to check-call with 42.26% of the range and check-raises the remaining 13.55%.
Now, if you shift your focus to the left side of the screen, we can start to examine the morphology of these ranges: what types of hands fall into each bucket.
Let’s go through the defense range from top to bottom, starting with the strongest hands.
The nuts (87s) are check-raising frequently, but not always. The key reason is that they’re not vulnerable; even if we just check-call, we can still get all the money in on the river with a check-shove, assuming the Button doesn’t jam the turn himself. Slowplaying also has a strategic benefit: it discourages the Button from triple barreling all-in with hands like 7x. This would otherwise allow him to expand his bluffing range and force more of our hands into indifference, ultimately letting him claim a bigger share of the pot.
For the same reasons, we’re often just check-calling with our four-straight (7x) as well.
The weakest four-straights check-raise for thin value and some equity denial. These hands aren’t strong enough to comfortably check-call two more streets, especially if the Button decides to shove the river. By raising now, we avoid getting put in a tough spot where we’re forced to call an all-in with what is essentially a pure bluff-catcher.
Sets and two-pairs are still very strong hands, but not strong enough to raise for value. They block a significant portion of the Button’s value range while blocking none of his bluffs, making a raise inefficient. These hands are clear must-calls.
Now we’re getting into the middle of our range. This turn puts many hands in a tough spot, as several previously strong holdings lose value. Take overpairs like 88–AA, which were high-frequency check-calls on the flop—these are still part of our defense, but now they’re vulnerable. The same goes for 6x hands, which remain serviceable bluff-catchers thanks to their blockers to top set and two-pair.
These hands need to continue at a relatively high frequency to prevent the Button from over-realizing equity with his semi-bluffs. Exceptions include K6s and Q6s, which are lower-frequency continues due to their lack of relevant blockers.
Nut flush draws and the top second nut flush draws (Kc Qc and Kc Jc) are strong enough to check-call. They carry significant equity and also retain solid showdown value when the river checks through, making them ideal candidates to continue passively.
Now we get into the check-raise bluff category.
The best candidates here are flush draws that aren’t quite strong enough to check-call, as well as combo-draws that carry massive equity when called. These hands still have plenty of outs to improve to the best hand, and when they do get folds, they deny a meaningful amount of equity. That combination makes them ideal check-raise bluffs.
Wrapping Up
As you move from preflop to the river, the strategy naturally becomes more technical and nuanced. That’s one of the main reasons you don’t see many strategy articles diving deep into turn and river play—the complexity is simply too much to cover in a single piece.
That wraps up Part 1 of the series. If this felt a bit dense, don’t worry, that’s normal, especially if you haven’t studied these spots in detail before. It gets easier the more you engage with it.

Til next time, good luck out there, grinders!
