Only exception is some DoN, or tourney close to bubble, basically where you dont want to risk, even with good EV+ in chips.
You cannot be afraid to loose whole buy-in. That reason you have BRM and 50 more buy-ins to loose.
Just to clarify here, no-one is scared of losing a full buy-in... but if you have a full stack and someone still has more chips than you and they happily call a 5-bet, it is generally a massive tell that they are a strong player and they have AA more often than not.
People going all-in on a 5-bet with less than AA generally have less chips than you already because they are weaker players, or they are on tilt, and can't even get into a 5-bet or fold situation.
We are talking about what are the right circumstances to fold KK in a cash game, not a tourney. I will happily call KK against shorter stacks all day long but someone who has sat at a cash game for a while and has a bigger stack than average is generally doing something right and will see a flop or fold with TT-JJ and AJ-AQ so I am not so happy about 5-betting all-in in this situation when I do it.
You can still 5-bet and hope to see QQ or AK but it is false hope more often than not against a good player. If we have limited information then stack size is a decent tell of whether they could be a good player or not.
