I have tried the trial versions of OddsOracle, CREV, Flopzilla, and
none of them really seem fulfilling my need.

What I am focusing off the table these days is,
splitting my range for more balanced plays in different spots.

I mean...I want some software that can do something like;
i.e. set 30% RFI range - mark 15% cbetting range on xxx board = shows leftover 15% for checking back range etc.

No program seems really do "range minus proportion = left over range"

Is there any program that sounds fit for my need?

Hope my question was clear enough.

My guess is, there's no software - yet - which does exactly what you're after. But given the amount of interest in this kind of thing, can't be long before someone develops such a thing.

Two that you haven't mentioned are Combonator and PokerRanger which you might want to check out.

I like CR-EV for this kind of analysis. It does have a bit of a learning curve but it's big plus points are:
- its condition editor is way ahead of the others
- the pop ups give you a nice visual confirmation of your ranges
- the 'layer' feature allows you, in one file, to model different board run outs which is useful for the sort of analysis you're proposing

And of course, if you're going to get into modelling villain's response, CR-EV is more than capable of handling that (something I'm not sure we can say about those other programs).

All that said, I'm pretty sure Matt Janda said - in the thread for his book - that he used nothing more than Flopzilla for the analyses for his book.

Good Luck.

Janda used Flopzilla and Notepad.

I use Equilab and Notepad, primarily because I already had Equilab and can operate it quickly. Equilab has a little-known function that allows you to narrow a range and count combos based on flop hand strength. (Pro-tip: Press the pie-chart icon once you've input a flop texture).

CREV seems even more powerful, but the learning curve looked too steep for my current purposes.

Thanks for the input.
Looking at all the programs mentioned above incl. CREV again.

Not made my decision yet...but Matt Janda's book sounds interesting.
Can I have the title of the book? assuming it's related to what I am studying right now?
