I believe someone mentioned CrossOver.
Please let me know if that works for you.

Just emailed you about the registration. This software looks promising. I hope I get my key soon

On a flop of KJ3 the software does not recognize A7 as a backdoor flush draw ? To me it only shows every combo of XX as BDFD. I would like to know percentages of this three card fds aswell.

Backdoor flushdraw seems to work for me here.
Possibly you've selected "using two holecards"?

hey scylla,

i saw a video of the now unavailable pokerrazor and it had a feature which i was hoping was on either crev or flopzilla. what it was was, you enter the villains range preflop then enter the flop texture. then you enter your (say) range of 20%, then it will list in the matrix all the hands in your range and each one's equity against the villain's entire range on this flop.

thanks

In CardRunnersEV you can just enter the decison tree for this situation, compute, bring up the popup with the EVs at the flop and press Alt+E to toggle to equities (standard display is EV).
I believe it's what you're referring to.

Where it can be selected ? I am using flopzilla.

Oh, I was referring to CardRunnersEV.
In Flopzilla one card backdoor flushdraws are indeed not available.

what do we do if our windows 7 installer is broken. i cant downloads the program

It sounds more like a windows problem ...
At least I asume you're having this problem with other software as well.
If not, please be specific about what error message you're getting.

Can't you repair your installation?

A couple of questions:

(1) I have an an Intel i7-950 CPU. When I bring up task manager it shows me 8 CPUs. Presumably this is because it has 8 cores or 8 hyperthreading contexts or what ever (I can't keep up with the intel architectures). When I run a CREV simulation, my CPU utilization only go to 13-14%. One of the 8 "cores" (or what ever) goes to 60-80%, 3 others show some activity while the other 4 look completely unused. Is CREV doing all it can to make use of multi-core processors? If anything could make use of multi-cores I would think monte-carlo simulations could! Perhaps I should change some CREV settings to improve utilization? This is not a big deal, just curious.

(2) I would like to have you add a "signal to noise ratio" stat. SNR is

SNR=

EV / stddev

// CREV calls "stddev" variance in the EV popup.

SNR is a nice dimensionless measure of the relative dominance of EV vs randomness (stddev) in a EV calculation. It is all well and good for poker players to focus on EV and the "long run" but if the stddev is so dominant that the "long run" takes 20 years to come then I may want to select a lower EV strategy that has a higher SNR, if such a strategy is available.

I can bring up the EV popup, look at the "variance" (stddev) shown and calculate the SNR by hand but that is rather tedious.

You might prefer the "coefficient of variation" (the inverse of SNR). You could also let the user chose if they want CoV or SNR displayed.

Getting software to run on multiple cores is not a straightforward proposition. There's a lot of communication required between the cores, which requires a lot of coding, while the speedup is usually much less than you'd expect. I've decided not to go there.


I'm afraid that would add another option in the menu; I'm trying to keep those down. Also, I'm not sure enough people would use it to justify adding it as a standard option. So I'll have to pass on this one.

Thank you for the feedback/suggestions!

Cheers,

Scylla

You are welcome. I am in awe of what you have done with CREV so I'm sure you know best regarding UI design.

Hey scylla,

I'm looking for an app where I can simply input calling ranges of players to act behind me, effective stack, pot size, and our holding - and output the ev of a shove in BB. I gather your program can do this, but it seems like over-kill (and overly complicated) for something so simple. Is there a pop-up or something within the program that can do this for me? I have had a look at the software and cant seem to do what I am trying to do!

Thank you.

If all the players have an identical range then there's a trick to make one villain appear to be multiple villains. This would probably do what you're trying to achieve. However, could you be a bit more specific as to what you're looking for? First you say that the players are behind you, then that the BB shoves. Possibly I misunderstood.

Say I'm on the button with x BB effective, I want to input SB calling range, BB calling range, and my holding, and output a value for the profitability of a shove.

Oh, ok.
That's fairly straigthforward.
No tricks necessary there really.

Just use the tree below and enter the ranges for SB and BB you feel are appropriate.
To edit a range, double-click it.

For Button's range just use "all hands"; you'll need it later to see which hands are +EV and which are -EV.



Press F7 to compute.

Hover over Button's "all hands" condition to see which hands are +EV and which are -EV.
You will notice that the results are a bit scattered.
This is because the results are based on a large number of simulations.
This won't happen if there's only two active players in the tree, but with three or more the monte carlo engine is used since enumerating everything is no longer possible due to all possible variations.
(with only two active players the math engine is used and all results are mathematically accurate; there's no scattering).

To reduce the scattering you can increase the number of simulations the results are based on.
For that go to "options->run settings" and increase "runsx1000" from 1000 to 10000.
At 10 million runs the results seem pretty clear.
There's still a bit of scattering, but don't worry too much about that.
Marginal hands never really affect the results in any significant way anyhow.

For your convenience, here's a link to the savefile for the pic above.

Currently effective stacks are 20bb. To change the effective stacks, press the "XY variables" button in the lower left and change variable number 1.
Just in case you're wondering, the reason why you can change all stacks simultaneously with the "XY variables" menu is because variable #1 has been assigned to all stacks. To see how this has been done, click the "stacks" button in the lower left.

I am trying to work out some basic stuff and see how profitable or not it will be to shove QQ vs a very tight 4bet range.

When I try to do an EV run it says no end of hand found.

How do I do this?

When it gives you that message the node where the error occurred will light up in red.
At this node there's a hand in a player's range for which no action is defined.
You need to add a "fold all hands" action to fold whichever hands are not in the player's raising range.

Is it possible to get CREV for free?

There's a $99 registration fee.
The trial version is free though
Other than that I don't think I can help you.

scylla,

playing 100BB's deep, is it possible to construct a tree for a multiple player hand on crev? or is it too difficult (and is more useful for analysing HU pots)?

Depending on what you're trying to do, multiplayer trees do tend to be much more complex. There's just much more scenario's to take into account. I certainly wouldn't advise building some massive tree trying to everything into account but more to try to simplify matters where you can.

scylla- ever considered making a PLO variant of your software? I would forever worship you.

Considered ... and decided not to.
Sorry
