Thank you for the detailed reply. I'll start training with equilab tomorrow.

A good approach would be to pick a spot (BB vs BTN single raised pot is a very common one).

I would make 3 columns: BB Advantage/Neutral/BTN Advantage.

I would drop a random board (before I add the appropriate ranges) and catagorize it as BB range advantage, neutral or BTN advantage in the appropriate column. Then, add in the BTN RFI range and the BB defend range and see who has the overall range advantage and then focus on the nut advantage (usually we look at 2pr+).

Do this for 10-15 boards and see how you do. This will be much more effective for you to start to recognize patterns. Keep working it as a drill and soon you will be getting most every board right.

You want to work on understanding what makes up a range and how both ranges differ from each other. For OOP cbetting I did a lot of work on this. This is what UTG open and MP flat looks like range wise preflop.

If you mainly look at the blue bars you notice a gap in Kx hands for MP. So you expect boards that are K high to be much better for UTG than for MP. If we look at the betting frequencies we notice that on average we only cbet ~27% off the time. Yet on K high boards we cbet close to 100%.

This as an example of what you need to understand before you can think about "which board is good for you". It's always about how ranges look like and what that means on this board. For OOP your opponent who cold called (not the BB) has a higher % of made hands already (pocket pairs), and suited hands. He also has a decent amount of Ax. In the example it's our 23% vs his 20%. Sure, we have stronger Ax, yet those are a small % off our range. We have 464 cards vs their 18. That's an insane difference. So even if we hit our ace, our AK and AQ is going to be a small % of those 464.
Because of this you don't cbet range but selective. Which is why Hawks earlier comes to the ~30%.
The exception is K high boards as shown in the image above.

For IP my general rule is "Relative amount of marginal hands with incentive to bet".
Relative amount: % of hands in your range
Marginal hands: 2nd pair, 3rd pair. Showdown hands that are weak-ish
Incentive to bet: The folding range of your opponent has solid equity against these marginal hands.

The example I use is BTN vs BB SRP. You are BTN. Board is A84r, how would you cbet? What about AK4r?
A84 we have a decent amount of marginal hands, 8x, 4x, pocket pairs (about 25% off range) When they bet (even a small size) our opponent generally folds 2 overcards to these hands. These 2 overcards have about 25% equity.
So we have a decent relative amount of these hands that have incentive to bet. Because of this we bet these hands often with a small size. When we do this we also need to include bluffs and strong hands in that small sizing. Else we never get called (if we don't bluff) or we get checkraised a lot (if we don't include strong hands). After we have done so we are already betting very often for this small size. Which leads to the simplification being said by OP, just bet everything for a small size.

What about AK4r? We have about 28% marginal hands. Yet the majority being Kx or pocket pairs have less incentive to bet. The folding range of our opponent doesn't have a lot of equity against these maginal hands. Folding range is undercards against Kx. Gutshots generally aren't folded so pocket pairs 88+ don't want to bet as much. 4x we have a lower amount of. Because of this we go for a less frequent betting and a bigger sizing.

If you think you understood that, how about the same boards but UTG vs BB? Is it different? If so, why?

pretty spot on analysis

i use snowie to see what it does but this guy actually puts in the work to see why and it does reflect what the AI recommends

range betting is just simplifying things since once you can get board that cbets high freq (like 2/3%+) its just easier for human brain to bet their entire range, and then work your way backwards to figure out which hands NOT to cbet to optimize

so for the EP vs MP spot on Kx if you range bet there, snowie recommends small bet 1/4 pot size

BTN vs SB on A84 go small for range as well, but on AK4 snowie recommends 2x pot bet size with just 1/3 of hands

obviously this is hard to implement if 2x and 1/4 bet sizes are not part of your game, but the takeaway is knowing when to bet small at a high frequency vs betting large at a low frequency

so the easier way is to use a solver/ai to see the results, then putting in the work like shaun pauwels to see why

This is very interesting, and i think i understand the spreadsheet. You took all the hands that UTG would open and found all the combos (cards collum) and then figured out what percentages make up suited, pocket, unsuited ect. so the boards that hit the high percentage cards for either range, would create the range advantage?
this makes sense and is something that i might set up for other common spots.

Keep in mind that it's the difference between both ranges that's relevant. But yes, that's what I did. I never find the range matrix as shown normally to be easy to look at.

You very rarely have range bet boards OOP. Especially when ranges are so wide such as SB vs BB.

You're going to have a betting range, a checking range.
Within that checking range you will have check raises, check calls and check folds.
I would sey cbet and check call are the two most taken lines. But you will have to mix a lot.

For check raising it tends to be hands that want to deny equity. Such as top pair, overpairs that are low (such as 99).

Are you talking about AK4r and AK8r on BTN. And then my question on how your strategy looks like if you were UTG instead of BTN?

Try thinking through it with the rule I laid out "Relative amount of marginal hands with incentive to bet".
Come back with an answer and I'll then explain. Seems like a better way to learn :).

Close.

On A84 UTG should bet more frequently (small size, 1/3) because there are lot of hands of the BB range with a decent equity vs 8x for example.

While this is true. UTG shouldn't have a lot of 8x in it's range.
So while marginal hands would have incentive to bet, there isn't a decent relative amount off them within the range. So their incentive to bet is lower than your stronger hands value betting.
BTN has more 8x etc so will bet often and small, UTG will bet closer to half pot.

This is the range my solve has:
