This is my biggest problem playing holdem. Sniffing out that I am up against a set and drawing thin. Does anyone have any solid recurring things they look for? Or is it more just a case of this guy wants to play a big pot and I'm not even drawing to a straight/flush etc.

Is it just a case of avoiding big pots?

I know that there are a lot of this and that and of course it all depends, but does anyone have any insight they can/will share?
