StoxEV: EV calculations with decision trees

You can download the latest version here:www.stoxev.com

StoxEV is designed to make even the most complicated Hold’em analysis a snap.



In StoxEV you to enter a decision tree with what you would do in a certain situation and what you think your opponent would do.. StoxEV will then work out EV, equity, chance of having best hand and any statistics you're interested in for all decisions, actions, conditions and holecards in the tree.



Easy to use, intuïtive hover and click interface. Hintsystem included for new users.

The entire decision tree is visible on your screen. Hover over any number to reveal more information on equity, chance of best hand (not shown preflop), chance of tie, EV, variance and accuracy of all numbers.



Hovering over the EV field will display the EV and variance of the decision and also individual holecard performance.



To edit a condition, just double-click on it and an easy to use menu will allow you to define it as you wish.

Preflop menu:

Postflop menu:


In case you want to treat different type of turn- or rivercards differently (for instance if it’s the turn, you have QQ, the board has a diamond 2 flush on it and there are no overcards then you may choose to act differently if the river is a diamond, an overcard or a dud). StoxEV uses a layer system which allows you to select the different types of cards …

You can display the desired part of the tree by using the scroller arrows:


Making a graph:
If you want to know how any number (stacksize, betsize, preflop raising range, number of remaining players in a tournament, etc) affects EV, equity , chance of best hand or variance of a decision then StoxEV can make a graph for you showing this dependence.


The StoxEV calculator includes Independent chip model conversion for tournaments and sit and go’s, rake, rakeback, cap etc in the calculations. Works for any number of players. Savefiles can be exchanged with other users, making it suitable for forum discussions and study groups.

Order of strength of holecards can be custom-defined. Most software imposes on you that for instance KQs is a better hand then 77, with StoxEV you can define this for yourself and even exchange your range.txt file with other users. There’s 3 ranges you can use in case for instance if you want different ranges in different situations.


Cheers,

Scylla

Hi there,

When I try things out I am seeing the EV for each individual decision. How do I see the total EV for the hand?

Just click on the Flop button and enter the flop.
Is that what you meant?

If you need an example, just tell me what you want to do and if my schedule allows it I'll make it and put up a pic.

Whenever you are involved in a pokerhand you're always faced with decisions. How much money you make at poker is decided by the quality of your actions. That is why every decision has an EV.
It also means that your EV can only be calculated for your decisions.

I'm not sure what you mean by EV for the hand. Could you be a bit more specific?

Re: ***Stoxpoker EV calculator 1.0.5 released***

Ok i will be more explicit....

So i am Button and i attempt to steal with lets say top 30% of hands...SB fold and BB defend with top 20% but with QQ+ and AK reraise me all in and i will call with KK+ and AKs.
Post flop he put me all in if he hit at least top pair and i will call with at least midle pair , also if he check i will shove 75% of the time. I am shortstack ..lets say 20$ for 100NL and BB has full stack of 100$.
How can i model this? Is it possible to do without a specific flop manually entered?

Absolutely, I've added the pic below



Notice the stop action if the flop goes check check and you don't do the blufshove. I'm asuming that you've given up in that case. The stop action will end the hand and let no one win the pot.

If you have another question let me know!

If you would like this savefile mail me at stoxpoker_ev@hotmail.com and I'll mail it to you. I don't think it's possible to share files at this forum.

I understand each decision has an EV.

EV for the hand was a poor choice of expression. I meant the EV for a particular street when the play had several conditions placed upon it. Each condition has a different EV calculation associated with it but I'm assuming the EV calculation that takes all (let's say 3) conditions into consideration is the one that is placed right before everything branches out into the 3 options.

Ok, after you do an EV run just hover over the action or condition your interested in.
The EV of the individual action/condition will be shown in a popup.
