Ok so I have a question.

I've been making solid mathematical ranges for blind vs blind and they widen in relation to the sb open range.

I know how many combos I need in my 4-bet value range, when the ranges were tighter it was obvious what to use but I've hit a problem here.

I need 131 combos.

If I use the range
77+, A8s+, A9o+

Then my 5-bet range gets overloaded with bluffs. This is because to work out my 5-bet range I need 37% equity against it with my weakest 4-bet value hand.

In other words 4-betting A9o makes me add 28 5-bet bluffs to get A9o to 37% equity.

You see, I have no guidance for putting together the 4-bet range other than the amount of combos. So I'm thinking maybe it's best not to use A9o in my 4-bet value range.

Would it not be better to use the range
55+, A8s+, ATo+

Without A9o my 5-bet range gets a lot less bluffs.

Now I think... how can one hand influence my entire range set so much? Surely the choice of 4-bet value hands should not be arbitrary right?

So... How do I work out what composition my 4-bet value range should be (i.e. how many pocket pairs to Ax hands)

This was not covered in the articles I read on gto range building, but then they never went as wide as this in their examples.

* I have a thought, am I supposed to extend the As, Ao and PP combos in relation to their equity. in other words keep adding pocket pairs until it has the same equity as my weakest Ao before adding another Ao? And do the same when introducing Kx hands etc

Help from anyone who has done this type of thing is appreciated. It's the composition I'm not sure about.

This probably would help:

Thanks but I'm aware of those articles.

So, if I wasn't clear before let me elaborate.

Opening at 35% bvb bugs would 4-bet for value something like 88+, ATs+, AQo+

However if we do an ev calc against a 5-bet range we find pocket pairs do amazingly well... for example

vs JJ+, AKs, A5-3s, AKo
77 is 40.84%
AQ is 37.44

It doesn't matter how many 5-bet bluffs we have pp still have higher equity....

So why don't we fill our 4-bet value range with pp's, going as far as 22 before we start adding AQo, that way our 5-bet range uses less bluffs.

I don't know what a professional 4-bet default value range looks like but I am wondering why we don't will out the pocket pairs, please tell me if I missed something obvious.

I admit the idea of using 22 for value before AQo sounds funny that's why I'm confused.

You'll be able to realize your equity with one hand over another, so just evaluating one hand's raw equity vs. a specific range can be misleading.
