Theoretical question about low pp's and implied odds

[gholizad]

I have recently been going through my hand histories and I think low pp's are one of the leaks in my game.

Alright, let's start with an easy question: Let's say you are on a button with 66's and somebody who's an average TAG player makes a standard raise $100 from MP1. How much should his/your stack be to make it +EV for you to call his raise? The quick answer would be: his stack should be at least >$700 which makes the right odds for flopping a set. But that's not true b/c there are lots of times when he has AK and does not hit so gives up, has QQ and flop comes A high and he gives up or flop comes all low monotone and he does not stack off. So what is a right play with low pp's in late position then?
