Can I add my own formulas in the Calculator tools?

Yes you can! Check out the last 2 minutes of this vid:
https://www.youtube.com/watch?v=sgdfSSQy-8Y

The formulas are just text files. There's no manual or anything yet, and its a bit fiddly, but the 'tester.txt' should provides an example of how to write the formulas and what variables can be used.

Hi again! Can I put 2 formulas in a text file to compare? For example I want to know what line has more EV, something like checking back on the river or betting for the value.

You could either do 2 separate formulas in 2 files and switch between them (or open up 2 separate combonator windows, i guess); only way to do it in one formula is do say 'line X - line Y' and see if the results is >0.

Can you add some pop-ups to choose hands? It's very annoying to choose it by hands.

you can just type into the text box...

I had in mind it is very annoying to type it.

Yup an optional card selector is on the todo for sure!

I misunderstood you. That's weird, though, I find it much faster to type than to search and click on cards. I would never use that feature if it existed unless I was on a tablet, but since this software is desktop only that wouldn't apply.

Hi again!

Your program is very useful to get analyze after sessions but I'm not a programmer and don't have any mathematical background.

Can you or anybody help me with the formulas? I want to put them in calculator tools.

I need to calculate:

1. Check or bet (I want to know what is more EV). And villain don't raise us, so that is a last action.

2. Bet (so we just bet and want to know what is our EV).

3. Bet-call or Bet-Raise All-in (we are facing a raise and want to know what is plus EV).

4. Raise (we just raise and villain don't re-reise us).

5. Raise-call All-In.


How do you think can this 5 formulas cover all game situation? Or we can add something else. Of course we calculate actions just in one street.

I add EV of call and EV of checkback maybe it helps to somebody. Check it with attention it can be wrong.

{EV Call (All-in or River)}=({equity-vs-group} * ({Pot} + {Call})) - ((1 - {equity-vs-group}) * {Call})
This is used to do the most basic EV calculation we always do when faced with a Call or Fold pot odds decision.

{EV check}=({equity-vs-group}*{Pot})
This will tell you what our EV will be when we checkback a hand with some showdown value.

I rethink a list of formulas I would like to see. In fact we only need 3 ones: check, bet (raise) and call.

We already have in the program the bet formula, and I have to write the remaining two and bring them in one view, and then they can be combined any way to find which line will be more positive (for example, check - bet and so on).

I wrote the above check and call formulas, but I can't figure out how to rewrite them with combos. Can you help me with this one and with another one?

This formula is wrong:
{Value in call}=(({combos-all} - ({combos-all}-{combos-group}))*{equity-vs-group} * ({Pot} + {Call})) - ((1 - ({combos-all} - ({combos-all}-{combos-group}))*{equity-vs-group}) * {Call})

When entering flops, turns and river cards to see how ranges hit those boards, do I have to keep manually typing the community cards or can I select them like flopzilla?

What Windows operating systems is Combonator written for?

Card selector is in the works.

Should work great on windows 95+ - but you can always try out the free version and test it on your setup before purchasing.

Maybe should be something like this :

{Value in call}=(({combos-all} - {combos-group}) / {combos-all})*{equity-vs-group} * ({Pot} + {Call})) - ((1 - (({combos-all} - {combos-group}) / {combos-all})* (1 - {equity-vs-group})) * {Call})

or this

{Value in call}=(({combos-all} / ({combos-all}-{combos-group}))*{equity-vs-group} * ({Pot} + {Call})) - ((1 - ({combos-all} / ({combos-all}-{combos-group}))* (1 - {equity-vs-group})) * {Call})

Just guessing cause, I have no idea what value on call means.

Value on bet ESTIMATES =

- equity when villain folds
- equity when he calls we win
- equity when he calls we lose

What Value on call estimates ? and value on check...

Value on Call means what is more EV? Call or fold.
Value on Check means what is plus EV? Bet or check.

Yep, but...

Fold is only good when call is negative... so use EV of call
And if value on bet is higher than EV of check, then BET, else check

For example:








EV FOR BET - 802

forgot to select all hands for call and check, so EV goes like below when done correctly,
EV FOR CALL - 597
EV FOR CHECK - 359

Clearly we should raise over villain´s raise.
idk if this is all right, there´s so many variables... lol

There seems to be some problem in Combonator when you assign weighted ranges and it calculates in percentages how big the range is (as compared to the corresponding number of combos).

For instance, give all suited hands a weight of 0.1. Then Combonator returns:

31.2 combos (correct)
3% (incorrect)

The correct percentage is 2.35%, or 2% rounded.

It would be cool if you could fix this! It would also be quite nice if the returned rounded percentage has one decimal extra (so 2.4% instead of just 2%).

Can you sent me a combo file for this, or post a screenshot with both the grid and output window visible? Thanks.

Sure. The situation as described above.

For a more extreme example, assign 0.1 to all hands.

132.6 combos, but it returns 100% instead of 10%.

EDIT:

If you then remove AA from the range, it will give 132.0 combos for 96%.

Now, note that 132/138 = 0.9565 = 96%, where 138 is 132 + 6 excluded aces. So I suspect that what Combonator does is making two tallies:

A = Weighted hands.
B = Excluded hands.

And then it calculates A / (A+B). (An extreme example is assigning some hands a weight of 10 to see this in action more clearly.) I think it would be natural to simply divide by 1326 instead (and if you want to allow for weights bigger than 1, that is, relative weights, then normalize all selected hands to their unweighted combo number and divide by 1326).

edit: wrong.

Hmm yes, I see your point now. Thinking...

Ok so I understand the issue here; combonator is also weighting the denominator of the fraction. So (in your extreme example), it is doing 132.6 of 132.6 combos selected. When it should be 132.6 of 1326 combos. In the first example, its doing 31.2/1045.2, where you are expecting 21.2/1326.

I'm not quite sure what the clean way is to fix this. The reason the denominator changes is that you can have preflop weightings greater than 1. In this case you would expect the denominator to change. Select all hands with weighting of 2 and you've selected 100% of combos, not 200%, which would obviously be nonsense.
