fwiw, I think he's set the price just right.

Could you mail me the savefile at stoxpoker_ev@hotmail.com and tell me what decision you're talking about (hover over it and press Alt+N to add a note to it)?
I should probably be able to give a good explanation and hopefully tip of how to solve it.

Also, it's always possible you have the math engine turned off and are using Monte Carlo.

Anyhow, mail me the savefile plz.


Mmmmh, need to add that one to my bag of tricks ...

Thanks, I sent the hand file. I have "Use speedup" and "Mathematical solution" checked in the "Math engine" menu. When I perform EV run, the progress bar dialog still says "Monte Carlo mode" though if that matters.

Ok, e-mail received.

Here's the reason for the problem.

You've sent me the following setup, where there's a large fluctuation in the EV in the decision with the note attached to it.


When I switch to absolute mode the cause of the problem becomes apprarent. Of the 100k runs only 0.03% or 30 simulations actually make it to that part of the tree (see red circled part).
The cause for this is to be found in the blue circled decision. Only 0.32% of the simulations make it past that point because only 76s is considered for the bb's range, while he folds the remaining 99.68% of hands. That means that 99.68% of the 100k simulations are folded.


As you may recall, in a player's first decision in a hand his range is determined. This means that you don't need to assign an action to all of the bb's hands here, you can just leave out the fold and his range will be 76s. Now, all 100k simulations will continue past this point as opposed to only about 320 of them.

If you remove the fold action and recompute you'll find that the earlier fluctuation is substantially reduced. If you need more accuracy, just go to "options->run settings "and increase the number of runs.




Yes, math mode only applies if at least the flop is known ór if all the action is preflop. Also, it must be HU. Since the flop is unknown, monte carlo mode is used.

Thanks, removing the fold branch from the BB made it much better. Still learning to use the program properly.

I'm currently updating the written tutorial to the program's current situation, maybe that will be of help to you.

The old one is actually still pretty current, you can find it in the installation directory under StoxEVtutorial.
Just open the file manual.htm with your internet browser.

I have somehow managed to lose my hand-ranges when I upgraded. Is there any place where I might find these files or do I have to make them again? I can't remember whether I uninstalled free_StoxEV or not.

The files that contain custom settings are:
- customconditions.txt
- customranges.txt
- preflopranges.txt
- range.txt

If you lost any of them, just reïnstall.

But what do you mean by "lost"?
Do you mean the slider is no longer working?
This sometimes occurs when the standard hand range is a number that for some reason does not exist in your custom settings.
If this is your problem, go to "game properties->edit preflop handselection", select a range and press Save.

in StoxEV, what are the hand ranges based on in terms of %'s? The top 50% of hands in stox is dramatically different than Stove.

I am aware you can customize them, i'm just wondering where they came from.

They are based on playability in NL.
Stove seems to be more based on showdown value (yes yes, I'm aware it's the order of performance against something like 3 random hands). A big difference between the two for instance is that in pokerstove a hand like 22 is somewhere around the top 60%, which in NL of course makes no sense.

Thanks for the reply. Did you decide their playability, or did it originate from somewhere else?

I wrote it a while ago and never changed it.

I don't mean to be annoying here, I'm just interested in how the rankings were decided. Was there any math involved or did you just arbitrarily assign values?

I've been working on my ranges a lot recently, and found yours very interesting.

No math.
That's just roughly the order in which I like my starting hands.

Flopzilla says my trial period has expired and it refuses to run.

I tried downloading a new version and installing it but no go.

Any suggestions? Does Flopzilla have its own thread? I didn't see one on the first page.
