i agree with you but that's pretty much first level thinking. there's so much more to it than just "knowing your enemies", f.e. stacksizes, positions, your image, potodds, gameformat etc. don't get me wrong, having reads is an essential part of succeeding in poker. but really, based on purely equitys between different ranges (check a program called pokerstove if interested and havent heard of it before!), KK is almost never a good fold preflop. as i said, there are some exceptions, mostly on tournament's moneybubbles where all the cashes have the same prize.
talking about folding KK preflop is actually one of the most redundant things ever strategywise, but here i am doing it! :D
e: oh you edited your post, makes my post less informative for you at least then
