I'll table this issue for now until I start using solver again bc I've forgotten what my problem was over the last few days.

Ok I'm going to buy CrossOver, but then I'll also have to get a Windows license as well.

Does it matter which version of windows I get?

Hello Scylla,

Using Crev heavily recently, it's amazing. I got two suggestions:
1. It would be great if you could assign a hotkey to equilibrium tool. Also if you could make the equilibrium tool run after pressing "enter" that would be great! (right now if I press enter, the equilibrium tool just exit)

2.

When I am studying on the NE, I often want to see how the NE would become after I remove one or more branches. But don't want to delete them(ex: I might want to compare between two trees later), it would be great if there is a function that could "comment out" branches temporarily!

Cheers,

The top option seems to have an EV of about 6.4k while the bottom one has an EV of about 5.7k. It's indeed roughly the same, with a 0.7k difference.

I don't think it really matters, but personally I'd go with Windows 7 over Windows 10, given that Windows 7 will come with an option to upgrade to Windows 10 anyhow. In that way you'll have both (I'm not an expert on the upgrade policy though, so you might want to check). Do make sure you get the 64bit version though and not the 32bit one.

Ok, I'll see what I can do!

When building a decission nod, like for example when in the BB facing a BU OR, when defining the BB 3Betting range and Calling range what happens if by mistake i add one or two hands on both ranges? I was expecting some sort of popup message/notification or something saying to me like "You have selected KQs on your 3Betting range too" but i dont get any so im wondering what happens or more likely how do CREV handles those situations? Cheers.

CardRunnersEV treats the top action first, then the second then the third, etc.
So if a hand is accepted by the first action, then it will go to that action and no longer be considered for the actions below it.
So basically, higher actions have a higher priority.

For more on this, please watch the video "How actions+conditions are processed" under "The basics" under "Help->Video manual":

Beginner question: How is CardrunnersEv different from the other Equilibriumsolvers when it now implanted the same mechanic? (i guess it right now is the worst working one since its newest? (In all honesty?) But is there any future plan to differantiate from the other softwares?
Is the expected value calculator, if that is what you can call it and the equilibrium solver two different things in your software? Two different functions so to speak.
Or does ev and solving the right move have anything to do with eachother?
And do you have good use of the old functions in your software with the solver available.
Lots of misunderstanding from my part ofcourse but maybe a simple explanation can be done.

Thankyou

Sorry for poor english aswell.

Hello Scylla,

As you know, there are two ways to calculate EV.

One way is just considering how much money you will make in the long run, no matter how much equity you have in the first place.

Anther way is to set the check down equity you have as zero, so you only gain equity if you get a better hand to fold or a worse hand to call and vice versa.

I wonder does the CREV have the ability to toggle to the second way?

Cheers,

CardRunnersEV is, and has always been, all-round software that's written to be applied to be as flexible as possible. You can enter any tree that you like and see how it performs EV-wise. It can be used both for cash games and tournaments, heads-up and multiway in pretty much any spot, as well as offering a wide array of additional tools and features. The newly added solver feature is simply a new feature, which is particulary helpful in letting users finish up their trees, as well as for checking leaks. That being said, I have no intent of turning CardRunnersEV into an equilibrium solver, it will just be one of its many features.

There's really only one way to calculate EV, and that's the first one. That's simply because that's how EV is defined. If I correctly understand you the second way would mean setting the pot to 0 at every decision? This would ignore the fact that often the pot offers an overlay, which justifies playing an inferior hand. For example, flushdraws are usually a "worse hand", but can be played due to the pot offering additional odds.

Actually there are two ways.

For example,
Board: 2 2 2 3 3 rainbow
Villain check on the river
assume Villain hold AA or QQ
Hero hold KK
Pot: 100
Bet:50
Assume if Hero bet 50, Villain will call with all the AA, and fold all the QQ.
Hero is considering between checking down/betting half pot

calculate using 1st way:

<HERO CHECK> = 0.5*100 = 50
<HERO BET> = 0.5*-50 + 0.5*100 = 25

calculate using 2nd way:

<HERO CHECK> = 0
<HERO BET> = 0.5*-50 = -25

Another example:

Villain check on the turn, Hero considering checking/betting
Assume Hero hold a draw which has 20% equity all the time no matter what Villain hold
Assume Villain has 80% equity all the time
Pot:100
Bet:50
Assume if Hero bet, Villain will fold 50% of time, and if Villain call, Hero simply lost the whole pot
Assume Hero will get 100% of equity if he check

(in the reality Hero will not lose the whole pot when Villain call, and will usually get more than 100% equity when Hero check down, but I will just simplify it for the sake of this discussion)

calculate using 1st way:

<HERO CHECK> = 100*02 = 20
<HERO BET> = 0.5*100 + 0.5*-50 = 25

calculate using 2nd way:

<HERO CHECK> = 0
<HERO BET> = 0.5*80(when villain fold I win those 80% equity I don't have) + 0.5*-70 (when villain call, I lost the bet 50 plus my 20% equity 20) = 40 - 35 = 5

To transfer the ev between 1st & 2nd ways is easy though, for example in a 800 pot CREV show the ev of AKs is 836, and it's equity is 86%. 836 is the ev calculated by using the 1st way. Then it's ev of the 2nd way is 836 - 800*0.86 = 148

Oh, right. I misunderstood what you meant in that case. This would involve comparing all expected end stacks to a checkdown action as opposed to a fold. I can take a look at it, but I don't think I'll get to it this month.

Trying to get CREV working with Crossover on Mac.

It loads fine, but when I try to run the program I get the follow error:

Cannot find 'MFC42.DLL'. Please, re-install this application




I've tried re-installing a few times, same error keeps coming up, any ideas?

Thanks

I found some earlier posts on this topic, and tried what they mentioned...

I placed the file below into the windows/system folder, as mentioned. I no longer get the error, but now the window just pops up like it's going to run, disappears after a few seconds and then nothing happens.

I assume you're using beta v316?
Please follow the instructions under "Missing dll?" on the download page:

Only recently had a chance to try out all the new features you've added over the last six months or so, and just wanted to say Thanks.

I first bought CR-EV about 8 (?) years ago and the amount of extra 'stuff' it can now do is extraordinary.

Add in the fact that I've never been asked for an extra $0.01, the fact that i've needed to ask for a new licence on about 3 occasions due to computers dying on me, and never having to wait for those licences, and of course the ongoing comprehensive support in this thread - Great Job, scylla.

Just playing around with some trivial river spots, to get a feel for the Equilibrium Solver. Wow. Sweet.

Couple of minor questions. It seems like, as soon as the Solver has finished, the first thing we're always going to want to do is Compute the tree. (Until we've done that, we can't hover over the 'custom' ranges.) Is there an argument for getting the Solver to automatically do a Compute when it's found equilibrium? I know we could write a script to (1) find equilibrium (2) Calculate EV but that feels fiddly. (Maybe I'm missing something. Are there any spots where we wouldn't want to immediately Calculate EV after finding the equilibrium?)

When I hover over the Equilibrium icon, the pop-up says that it's only available to registered users. Is that correct? I feel sure I heard/read that the solver is at least partly enabled in the trial.

Minor points.
Great work.

It would be entirely possible to do an EV run immediately after running the solver. A possible downside might be that someone might want to save first, or possibly do something else.


Oh, that hint is actually incorrect. This was only at the first release. Since then the solver has been made available to trial users, but only for the board Td9d6h. I'll correct that hint for later versions. Thank you for pointing that out.

Yep. Fair point.
Thanks, scylla.

Hello Scylla,

Again, CREV is really amazing. But I've noticed something which is a little bit weird.

When using the equilibrium tool on the turn, it's usually super fast (ex: usually it could get dev < 1 in a 800 pot within 15 seconds). But sometimes it never reach to equilibrium when the scenario is really simple.

http://www.FunP.Net/486389
(I put it in a .rar because the online space wouldn't allow files in .stx form, it's not a virus)

In this file the range for SB/BB are KK&JJ / QQ(which is very simple,but the software could never reach NE). But If I change the range to top 30% of hand using the slider( a somewhat more complicate range), CREV could reach NE in 15 seconds.

Cheers,

Pokoteng

Yes, in ultra-tight ranges the algorithm sometimes doesn't converge. I expect to fix this in later versions.

Really good feature. Hope you will add it soon.

Thanks.

Is there a trial version for the software? If so how long is it and does it include all features?
