Calling Equity? late 20/180

Realistically, what is my best chance to double up? Well, I will have to get some cards and actually have someone call, or get lucky when someone calls my Q8 (or whatever) allin with an AT etc and double up that way.

You'd think you had to be be up against similar ranges in the K9o hand. K9o runs into too many wrong-end 60/40's and is easily dominated otherwise. At the best, you're hoping to flip pairs lower than 88 OR dominating something. That doesn't mean you call here. The key to the Q8 > AT hypothetical is first-in vig, because you can tick a few points of FE into the factors.
