I guess I already found it by using Alt+F

Another small question, if I fill in a text input it doesn't add just the combos I want but all the possible combos (fe I want to add 4h2s to a 80% range, but it adds the whole 42o to the range). Is there any way around this?

Correct!

CardRunnersEV does not allow you to filter for suits in the preflop fase, since it doesn't work like that in a real hand either. If you want to filter for specific suits, you'll have to do so postflop, once the flop is known.

Hi,

is there a way in flopzilla to see how much equity have range vs range?

No, the main purpose of Flopzilla is to show how a given range hits a board (in percentages and in combos). Given that the interface also included a "dead cards" section, I decided to add a bonus feature where the equity for range versus hand was also displayed in case specifically two cards were entered. However, that's as far as I think I should take that part of the interface.

If you're looking for EV calculations, range vs range equity, unexploitable shoving, equilibria, etc then I'd like to refer you to CardRunnersEV. Its decision-tree based interface has been specifically designed for that purpose.

Adding range vs range in Flopzilla would require adding an entire second section with a matrix and filters. It would enormously complicate its interface. Also, the amount of effort that would have to be done in order to set up a situation would be comparable to the amount of effort required to set up a decision tree in CardRunnersEV. In that case, you might as well use CardRunnersEV. In fact, if you're just interested in equities, then its free (infinite) trial should even be enough to do this up to the flop.

scylla,

I want to take cardrunnersEV on holydays over xmas. For that I need to put it momentarily on my portable (it's now on my PC) is that possible?

Sure, not a problem.
Just send a mail to support.
And please remind me that this is a temporary transfer.
I'll make a note to reactivate the old license once you request so.

Hi Scylla,

I have just bought CREV and would like to do some work. But first I need to get to know this program, hence I have some questions to you.

In this section we can work out the best strategy. However, we won't see a flop, so the hands' postflop equities are irrelevant. Also, the card removal effect doesn't work for ranges.

Therefore why is EV of this range (74.66%) higher, than this range (also 74.66%), which contains more suited hands and less offsuited junk?

You said that Strategy sb/bb is counted before any blinds are being posted. So which number is more important?
- EV of our raise only?
- weighted EV of raises and folds?
- strategy sb/bb ?

I'd like to develop a preflop 3-betting strategy UTG vs BTN.

UTG:
- opens 12.5% { 22+,ATs+,KTs+,QTs+,JTs,AJo+,KQo }
- 4b/c only 3.0% { JJ+, AKs, AKo } (so for now he doesn't have any 4b/f)

BTN:
- 3-bets 8.4% { JJ+,AKs,ATo+,KTo+ }
- 5-bets 3.0% { JJ+, AKs, AKo }



Why it shows us that BTN 3-bets 7.78%, while in fact he 3-bets 8.45% of his range? (I double checked it, there is a 8.45% range inside)

However, once I remove "Fold" from the BTN's first action (which defines his range), the EV of UTG's opens goes down.

I know that folding is 0EV, but it looks like there is no way to make the EV of any range lower than 0. I mean, we can 3b any trash IP and the program still shows that we are +EV, while I highly doubt it's true, although I haven't taken any postflop actions into account.

Given the opening range for the UTG - how can I work out the best 4b/c strategy for him and the best 3b/f+3b/5b strategy for the BTN?

There's no such thing as postflop equities.
There's just equities.
If all the play is preflop, then the equities you're getting are averaged for all possible boards.

Yes it does.
For example, try letting SB raise only Ax hands.
BB's 3bet frequency will drop from 29.2% to 28.4%.

As far as I can tell, both have an EV of 0.52.
The first range will perform slightly better though.
If you're talking about some other setup, then please mail a savefile to support.

The weighted EV of raises and folds is the number to be looking for.
For example, it's easily possible to dramaticlly increase the EV of just our raise if we only raise AA. However, the total EV of our decision would drop dramatically since we'd be folding many other premium hands. It's the EV for the entire decision you should be looking at.

As for strategy EV, that number is only important if you want to determine if you should be playing at all. For example, if you need to post a 0.5 blind, but your strategy only makes you 0.45 blinds, then you should not be playing that strategy.


That's due to card removal.
UTG's range is rich in aces and kings.
For that reason, the chance that BTN álso holds a premium hand drops from 8.45% to 7.78%.

A player's range is determined in his first decision.
So in your first setup UTG was up against a BTN who was dealt a random card from the deck.
If you remove his "fold all hands" action then he will always hold a top 8.45% hand.
Given that UTG is now up against an artifically strong range and BTN never folds, his EV will drop dramatically.

You have UTG folding to a 3bet 78.5% of the time.
That justifies 3betting with trash.

Please do keep in mind though that you have not included SB and BB into the calculations, so in reality you should be using tighter ranges.

Just enter the strategy for one player and then use the Max Exploit tool for the other one. Once again though, please keep in mind that you have not included SB and BB into the calculations, so you should interpret all results with a grain of salt.

It's also possible to write a tree where you dó include SB and BB (no need to go overboard with details on their play though; just keep it basic). After that, check which hands are +EV for hero and delete the -EV hands. Do so while moving back through the tree and deleting the -EV hands; recompute after every delete action. It's the approach described for finding optimal play in the article you linked to at the start of your post.

So the card removal effect actually do work for ranges! That's cool.
And in order not to be up against an artificially strong range, I should include the "Fold" action to everyone, but the very first player to act. Therefore my first scenario is correct. Will try to play with this stuff some more.

Thank you very much for your answers.

New noob questions.

#1
How can I roughly estimate what's the optimal opening ranges say from UTG in %? My poker experience tells me, that it shouldn't be like 50%, cause I will get 3b too often and will have to play with a very weak range OOP.
But what about 12%? 13%? 16%? If I would specify my postflop play and the play of an average opponent, combined with a 3b/4b/5b strategy - all together - then would I get the answer? Seems ultra hard...Monte Carlo would prob need like 50-100M of simulations.

#2
Say my flatting range consists of { JJ-TT, AQs-AJs, KQs }. I'd like to x/r with OESD using my both holecards, which filters out KQs only. However, it looks like CREV does take other hands into account as well, even when I specified the board (must be JTx in that case):


#3
If possible, could you please take a look at my strategy designed for UTG (he is named as Cutoff)defending vs BTN's 3b? I sent the .stx file to support@cardrunnersev.com

Do you have any of the hank rankings (sklansky or nash) already written out ready for import. like AA, QQ, JJ... ?

I have included Sklansky-Malmuth and Sklansky-Chubukov as standard hand rankings in the beta. So they're there. I don't have any other rankings available.

You would need to build an incredibly complex multiway tree for that. I don't think trying to mathematically calculate this is the correct approach. You should probably just check your database to see how different hands perform from different positions. Sorry ... you can't apply math to éverything.

I'd need to see a savefile.

Ok, I've replied to your mail.
The tree looks fine, other than that I'd advise not to go all the way to the river if the flop+turn+river are unknown.
Try just sticking to one unknown fase.
Beyond that, trying to build a detailed tree can get incredibly complex.

I downloaded the beta, but the only two hand rankings I see are
"no limit" and "poker stove".

That's really weird.
There should be 3 more of them.
Are you sure you haven't deleted the other 3 ranges by accident?

Anyhow, please mail support and I'll send you a file to fix it.


PS:
Ah ... I can think of one way for that to happen.
It was probably like this in one of the earlier versions of the beta.
The update process will indeed not update the file.
If you go to your main directory and rename the file preflopranges.txt into anything else, I suspect the software will notice the missing file and fix it, giving you the correct setup.

That worked. Thank you!

Hey Scylla. Have another question. Is it possible to select multiple elements (say conditions)? Ctrl doesn't work.

Also want to thank you for a great product and great support.

No, you can only select one.
If you want to import conditions from another action you cán do so however in the postflop menu by clicking on "Import from other action". For an explanation of this feature, please turn on "Help->Display hints in menus" and mouse over the "Import from other action" button.

Hello. A couple of days ago I started to use beta version. I was creating multi-conditions and everything worked well untill it froze at some point at the moment I tried to open multi-cond menu. After that any time I try to open multi-cond menu it freezes again. Is it my PC or some sort of bag?

Clearly a bug.
Could you please zip the directory /conditions and mail it to support?

Please explain it to me. What exactly should I zip and how? Thanks

Go to CardRunnersEV's main directory and zip/rar the /conditions subdirectory.
You can use a program like WinRar for that.
Then mail it to support so I can see what's wrong.

When I start up CREV beta I get the message to update, but when I go on the new look website I can't see a link to the latest beta. When I try downloading from the link, I still get an old version of CREV, rather than the new beta.

The latest version of the beta is v2.8.5.
You can download it here: http://www.cardrunnersev.com/download.html

Click on "Click here for the beta".

Has anyone participating in this thread developed any useful scripts that they would be willing to share or sell?
