I may be wrong to think like this but when I approach ranges I think like this. Yes, villain has a range but out of all of the different hands in his range he can only hold one. So I try the best I can to whittle it down as best I can. Also notice that the more hands you remove from villains range the smaller our equity is. The range posted above seems a little wide. Which is why I said if we were involved a little more we could tighten that up. And we also dont have to play for stacks here.

edit: remove sentence "Also notice that the more hands you remove from villains range the smaller our equity is."
