I'm sorry if this was already answered somewhere but I can't find it anywhere. What do conditions "backdoor flushdraw or less" and "gutshot or less" mean?

In Cardrunners EV there is no such options.

There is Gutshot or More (MORE, not less)
and >=Backdoor flush draw. And it also means Hand equal or better (backdoor or stronger FD).

Oh, I must've been using an outdated version.

You're probably still using the alpha.
Please upgrade to the beta.

I am confused now. You said both are standard deviations.
Of what? They can't represent the same standard deviations.

I want to know so that i can workout confidence intervals for the ev of a play. Which one should I use then?

Thanks

When the Monte Carlo engine computes results, it will base these results on a large number of simulations. Because of this method, all results will only be an estimate. Since I felt, given that all numbers had an error, that it should be made clear to the user what that error was, I've added a field (std: ...) behind the most relevant numbers.

For example, see the pic below. Here we have a popup that says (amongst other things) that, based on the simulations, the equity is estimated as being 33.9%. However, the software expects to be off by approximately 0.27%. So reasonably, you can expect the actual equity to be within the range [33.6%,34.2%].



So, basically, whenever the software says something like:
Equity: 56% (std: 1%), it's basically saying "my best estimate of this number is 56%, however, it's perfectly reasonable to expect the real value to be between 55% and 57%".

This applies to any number computed by the monte carlo engine. The std number is simply the expected error in that number.

And the Variance is just a measurement for how much you can expect your stack to fluctuate by performing a certain action.

So if the popup says:
EV: 8 (std: 1) Variance: 40
It means that
- the expected value of the move is estimated as $8.
- the error in the EV is $1, meaning that it's most likely between $7 and $9.
- you can roughly expect your winnings/losses to fluctuate between -$32 and $48

Thanks a lot for these explanations.

How long does it usually take to finalize the process after paying? Been about an hour so far.

@all following this thread: are there any skype group out there made of players sharing experience and tips about CRev?

I've been using it a lot lately, setting up strategies and all but really not sure of some parameters (equity realization and checkdown action for my preflop gameplans for example).
I am keen to join such a group.

Thanks

I believe I've just sent you your key.

Have been long time since last time playing with CREV.

Now I have problem with script result - I can see only as much data my monitor height allows. Scrolling down is scrolling down only backround where is desicion tree.

There should be a scrollbar to the right of the script window.



Also you can scroll down with your mouse scroller.

LOL. Actually I am not ******ed.

After running script -> Graph shows up -> Scrolling down (whatever method I am using) moves down only "background", where is desicion tree). I can only see like 50 first data lines instead of all 150 and "text output".

I was just checking if perhaps there was a bug and the scrollbar didn't show up for you.

Ah, ok.
I hadn't realized you were talking about the graph results.
The upcoming version has the "text output" button on top, so at the very least you should have access to all data through that.

scylla,

I have a problem when graphing 2 variables in version 2.8.7 of the beta. While the graph is in progress, there is a graph in the bottom left hand corner of my screen at increasing levels of completeness. But when the graph is 100% done, all I see is a table of outputs. How do I retrieve the graph?

Ben

Are there paid coaches reading this thread who would be willing to run through some guided examples setting up trees with me? I have some very specific (yet very basic) trees that I'd like to setup, but I'm new to the software. I've watched the tutorial videos and have made small progress, but would like some additional paid help to make sure I get the methodology down right.

Maybe I don't have all the answers but I'm willing to give you a hand if I can help you.

Samuel.Jimenez.Diaz is my skype.

If anyone else is good with scripts and want to discuss stuff, let me know please

Samy

That graph system is just used to give some indication of the progress.
I've usen a graph system because some matrices are a bit too large to show in a mini window.
A graph always fits.
I suppose I could add graph output in the graph window though.

Hi Scylla,

Is it possible to filter topX% of the hands (without regard to the EV of the hands) automatically?

Example:



I want to call with 60% of the hands, but here I only call with 7.45% of the hands (that are those with an EV higher than 60).

Do I have to do it manually? Or theres an option to set "Call with the best 60% of the hands" somewhere?

Thanks a lot

You could create a script that does this for you.
For that, you would need to attach a script checkpoint to the call condition (for the example below I'll use script checkpoint 1).

Then it would have to take the following steps:

1) Set All Hands at Location 1
2) Perform EV run
3) Select top 60% according to EV
4) Perform EV run

So basically the script would look like this:


And now, every time you want to run it, just press F4 or the "Run script (F4)" button.


PS:
I notice from your screenshot you're using a pretty old version of CardRunnersEV. Please go to the website and update to the latest version: http://www.cardrunnersev.com/download.html

Thanks Scylla, will take a look at it.

Uhmmm scripts in checkpoints, loving this program so much

hi scylla,

if you have someone betting the top 60% of hands but you've left the flop cards unknown, does that mean they bet the top 60% of their PF range, or does it actually go through flop by flop and choose the best 60% for each one?

thanks!

You would be betting their preflop range.
The software does not do flop-by-flop (which is basically impossible).

If you want to do this anyhow, then you can get pretty close with a script. You'd need to write a script that goes through a "large" number of randomly drawn flops (I'd say roughly 30 of them should be plenty) and keeps track of the results. For an example, please watch the video on scripting "Unexploitable shove on unknown board".





PS:
Alternatively, just using the top 60% from the preflop hands will probably get pretty close to going over all possible flops. So I suspect just using the preflop ranking will be plenty. The reason is that the preflop rankings are based on their performance on all possible flops anyhow. For example, let's say we have the spot below where we want SB to just call the flop raise and then push the flop with his top 60% of hands:

We could solve that by making the entire hand take place before the flop. In order to avoid reaching the flop, instead of making SB call the bet of $9, we make him raise to $9.01 instead. After that, we make BB raise to $9.02. The action is now again on SB and we're still preflop. Now make SB push the top 60%:

Hi Scylla,

Im getting a problem with very small variables (crev represents them as 3.14e-6 or similar). They break scripting, prob due to the exponent. Maybe round these down to 0? Also, I was wondering if it could be possible in the future to vary a range, either using a range string or some other method (saved range?) Thanks a lot!

Ah, kind of an oversight on my end there.
Could you do me a favour and send a savefile+script to support?
I'm pretty sure I know what you're talking about, but I just want to be sure.

I'm afraid I don't fully understand.
Could you be a bit more specific please?
