pushing/equilibrium problem

[ahmngrn30]

I've played almost 10k sitgnos and am still having problems with this. Every time I plug a hand like this into sngpt or sngwiz I get frustrated and don't come away with any conclusion on what my range should be.

Example:

Blinds: 100/200

BB: 1780
SB (you): 1760
BUTTON: 1855
CO: 1945
CO+1: 1570
CO+2: 4590

It folds to you in the SB. The BB is a great player that you've played with a lot before. Say your typical shoving range is 70%. He knows this so he's calling with 29.9%, but I now know that he knows this. so now I'm shoving 51.1% but now he knows that I know that he knows so now he's calling with 21%, but now I know..... etc,etc for infinity.

It obviously gets insanely more complicated when it's not just two players but I'll just start with the previous example.
