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.

Oh, kinda weird, it should expire tomorrow.
Runs fine here though.
I'm posting the new version in about 8 hours from this post.
You won't need to reïnstall, just start the program and it will update itself.

Flopzilla thread is here:
http://forumserver.twoplustwo.com/45...alysis-390299/

not sure if it has been answered already in this thread...

the monte carlo engine pisses me off. when trying to work out a HU strategy, the EV results get more and more widely dispersed towards the right end of the tree.

so when i get to what is +EV to call a 5bet with it will give radically different results everytime i press run.

eg - atm 88 loses 15BBs when i call a 5bet shove with it.
next run it wins 15BBs whilst 99 loses 3.6BB and TT loses 11BB!!!!
next run it loses 5BB
next run it wins 12BBs

these are obviously differences too large to be acceptable as i don't know whether it is pretty good or pretty bad to call a 5bet with 88!!!


is there a way to vastly increase the trials


i currently use speedup, mathematical solution, forced enumeration and merge monte carlo and math

ok, found out why now. i need to change the amount of run settings. what do you think the optimum amount of runs. mine was on 100(x1000)

just changed it to 10,000 (x1000) runs and it still isn't great but takes about 90 seconds to run

Could you send me the savefile at stoxpoker_ev@hotmail.com and I'll have a look if there's some improvements that can be made.

Is there a way to weight specific hands in a range like in flopzilla?

Yes, in both the preflop menu and the postflop one you'll see a button that says "100%". You can set a weight there. That particular condition is now weighed with that percentage.

Please observe that if you for instance want to weight AA-QQ with 30% preflop and the rest of some range with 100% that you'll have to define two separate conditions here. One for AA-QQ-30%, the other for the remaining range.

For instance the pic below shows what it would look like if you weighed JJ by 20%, KK-QQ,AK by 30% and AA by 50%:

I should have been more specific, i meant without multiple conditions for multiple weights. You answered my question though. The only reason i ask is because it would be much easier to save (for later use) a whole range as one condition as opposed to multiple conditions making up a range.

anyone else getting the error "Download failure - Failed to download one or more files. Would you like to try again?" I went to the site and re-downloaded the full commercial version, but I keep getting the same message.

edit. looks like the free version is on 2.3.4 while commercial is 2.3.3. Is that the issue?

There was a problem with the auto-update process. It kept giving errors.
I fixed the problem but it requires a reïnstall.

Go here and read "to all current owners": http://www.stoxev.com/get_the_latest_version.htm

yeah had the same problem yesterday, i ended up uninstalling, downloading the commercial version (2.3.3) and reinstalling and then it worked fine (and it's still working today)
