So I've always been really bad at mathematics. I mean REALLY bad, I can handle 2+5-4=3, but when it comes any more complex than that, I'm puzzled.

So today I've been trying to figure out a strategy to use in push/fold situations about 15-20BB deep as I think this is the biggest leak in my game. A lot of villains seem to minraise a lot in this phase of a husng (and I do too), and I'm looking for a way to exploit that.

I didn't even know where to begin, so I started with this: http://www.fpppro.com/fold-equity-calculator.php and Pokerstove.

This is the kind of a hand I'm having problems with. I want to explore all kinds of scenarios and that's why I need an application to do the work for me, this is just an example:

25/50 blinds, Hero has t1000 before posting the BB.

Villain (SB) raises to t100, Hero (BB) shoves t1000

For simplicity's sake, we happen to know that Villain will call exactly with top 10% of his hands here. Hero has decided to shove 40% of his hands. I stoved this and found out that Hero's range vs Villain's range is 37-63 in Villain's favor. Now I used the calculator behind the link above to find out how often Villain must fold in order for this push (with 37% being my assumed equity% when called) to be profitable, and found out that he must fold 56% of the time. Easy!

But HERE is my question. Imagine I want to make a chart about hand ranges I want to push with in these situations. So let's say I know in the above scenario Villain will call a shove 44% of the time or less (100%-56%=44%, doesn't matter if it's less as it just adds profitability) and when he calls I have 37% equity vs his range. How do I calculate the range I should push with here? Is there a software or something that would do the math for me here? Links? If not, is there any EASY way to do this without a calculator? I know this is kind of lame, but I couldn't figure this out by myself.
