Hello, I would like to find the equilibrium of a situation in cash game.

I raise from Button, SB fold and BB push. What is the best range to call to avoid being exploited and win the max money here ?

I thought there was an automactic way to find that, but I think I was wrong.

Any help ?

You're probably looking for the optimal calling range versus bb's pushing range.
For that, go here: http://www.stoxev.com/optimalcalling.htm

As for the tree, just setup a situation of button versus bb. No need to include the sb, since he folds anyhow and is therefore not an active player. By making this situation hu StoxEV will be able to use the math engine, which will give you mathematically correct results.

Thank for your answer however that is not exactly what I want.
If I remove all negative EV calls, I will be easily exploitable by someone increasing his Push range.

To avoid that, I need to find calls with negative EV to keep the best general EV with my whole range without being exploitable. That is the equilibrium. Such result could be found only with many and many tests withs different ranges. I was hoping something easier. With the equilibrium we get an unexploitable strategy.

The equilibrium would give the calling range of this equilibrium and the push range of this equilibrium. When we have that and someone call or push outside theses ranges, we can adapt in full awarness of being exploitable or not.

Sorry, english is not my native language, I hope I was clear enough.

Ok, sounds like you're looking for this:

Just let the button make the raise and then let StoxEV figure out the unexploitable shoving range for the bb.
This will also tell you with which range the bb should be calling the shove.

Group to study HU cash:

I'm looking to start a group to study optimal HUNL cash via StoxEV. Specifically I want to make some complex models of various player types that we can easily tweak ranges on. For example we would probably start with shortstacking fish and progress towards a thinking 2+2 lag/tag. I have a couple of other ideas as well involving opponent modeling and credible intervals for ranges. If this is something you are interested in and you are relatively competent with StoxEV and a winning online HU player, then shoot me a PM.

help/feature request: Is there a way to provide a short paragraph description with a .stx file?

I'd like to be able to have a description of what the saved file is about. E.g. "analyzing a 3bet scenario with villain so and so". Sure, I can get some of what I want with long file names like "3bet_against_ted_the_super_nit.stx" but some in-file notes would be nice.

If such a feature does not exist it should be easy to add.

As usual, you are way of ahead of me

Is this a bug? In this picture:


The probability of UTG+3 hits ">=set" and the probability that Button hits ">=set" differ. I would expect these probabilities to be the same or, for UTG+3's probability of hitting a set or better to be slightly higher due to card removal.

I did this with "Runs x 1000" set to 1000 and UTG+3's probability is always higher than Button's. The only hands possible here on the flop are sets and boats.

EDIT: when I mouse over the probabilities of hitting sets the std devs are 0.03% and 0.09% for button and UTG+3 respectively.

try giving each player a specific hand. i.e. give AcAs to utg and 7h7d to btn.

oh, and your results aren't weird. after the 77 guy has flopped a set there are only two board cards left for AA to make a set with ldo.

edit: if you want to see this just put two hand conditions under utg's flop bet. first hand condition being ">=set" and second hand condition being "all hands".

There ya go

Did that. Same result.
Ah, that is what I was missing. Pretty obvious in hindsight

Did that and I now see the two >= set conditions displaying identical probabilities.

I still have a question though about the actual result: 12.5%, stddev .02% (just recalculated with a higher iteration number that gave stddev .02%)

Isn't the probability of missing a set on the flop

48*47*46/(50*49*48) ==> 88.25%

so the probability of hitting a set (or a boat, which is excluded from the probability of missing a set)

1 - 88.25% ==> 11.75%?

There is about 30 std devs difference between 12.4% and 11.75%. What else am I calculating wrong here?

I'm pretty sure my calculation above for "not hitting a set" includes "not hitting a boat, not hitting quads" and neither a flush or straight is possible on the flop with both players having PP.

Are you using a high quality RNG? Stupid question (of course you are) but I clutching at straws here until the next enlightening post

so you're using 48*47*46 for the cards that don't make a set for AsAd, right? You're forgetting that 7h7c is also removed from the deck.

btw, this isn't my program and I know nothing about programming. i do have much love for scylla and StoxEV though.

You're forgetting that villain has AA, so the flop will be drawn from 48 cards which contain 2 sevens.
This makes it

46*45*44/(48*47*46) ==> 87.78%

and the chance of >=set is 12.23%.

The 0.2% discrepancy is because of the posibility of flopping a full house with for instance a JJJ board, which is considered as >=set.

This whole three of a kind board problem is hard to deal with by the way, because in other situations you dó want it to be included in a stat.

Thanks scylla and WillyT. I am so f***ing slow. Well, this has been a good exercise is finding tons of minutiae that slip right past me.

Welcome to combinatorics and card removal 101.

I'm not trying to tear him down or anything. I think StoxEV is an awesome tool. I'm just trying to understand discrepancies between what I expect and what I see.

I got what I wanted in asking my questions:

• my mistakes pointed out to me
• more faith in the correctness of StoxEV (not that I doubted it much after having my first goof pointed out).

Thanks again guys. I hope my next question will illustrate some subtle misunderstanding of mine rather than the crude mistakes of my last two questions

Thanks for your patience.

I keep getting an error. "The cabinet file 'disk1.cab' required for this installation is corrupt and cannot be used." Same problem with flopzilla. Tried downloading both installer multiple times and downloaded/reinstalled windows installer 4.5 just in case. When I click ignore it aborts the installation and the error code is 2350.

Windows vista and all patched up. UAC disabled and running as admin.

This error is causes by a faulty download of the .msi files.
Try storing to disk first.

Right click save as, I have, multiple times.

Redownloaded Flopzilla with IE instead of chrome and now the installer runs fine. Really have no idea why neither of the two times I DLed it with chrome didn't work.

Hey Guys,

I'm pretty new to StoxEV and pretty blown away by its huge amount of features and possibilities.

For example this hand:

9man SNG, 50/30/20 payout.
I set it up and wanted to see if a go'n'go has a positive expectation. Could someone check my file and see if i did everything right?

It says Ev:-0.10 for "Raise to 500" does this mean it calculates all the possible outcomes (pre- and postflop) and in the given situation raising to 500 would be a -ev play?

Hi Jurrasstoil,

Looks ok to me, that would indeed make the play -EV.

Cheers,

. forgot all i said =/ i get it ! lol

how do you save the graphs?

thanks again
