I would like to discuss a pretty common topic for a bit. Most seem to agree that folding KK preflop in a 100bb deep cash game is a no-no. What I don't understand is how there can be a scenario (like a villain 4betting you all-in preflop) where most people think that QQ is an auto-fold and KK is an auto-call. I see hands like this a lot where the HH shows Hero with QQ and most posters agree that Hero should fold, but if they held KK then they wouldn't be able to get the money in fast enough. My questions to those people are:

1) What range do you put villain on to be auto-folding QQ?

I'm assuming that to auto-fold QQ villain's range is something like QQ+.

2) How does that range look vs. KK?

If QQ+ is the range you assign to villain then how does that look when you hold KK instead? KK is 50% vs. a range of QQ+. I think we can all agree that AA is more likely to 4bet all-in preflop than QQ. Since we are 50/50 to start off with vs. that range and AA is more likely than QQ, it seems to me that calling with KK in a situation like this is at best break-even and probably a bit -EV.

If you are the type of player who doesn't mind taking 50/50's for 100bb's then fine. I don't think most players are that type. If you aren't that type then how can QQ be an auto-fold and KK be an auto-call (meaning you don't even have to think about odds/EV/etc.) in a situation like the one I've described?
