Ive had lots of KK situations I wished layed down because of the same situations you list. Its hard not to push back with KK.

Let me ask, would this be wrong? Just call the raise and go to the flop instead of laying the KK down preflop. That way you have a power hand going into the flop and see how that hits you. Thats what Ive started doing and if an Ace comes on the flop it makes it easier for me to let go. If a K hits the flop then your sitting pretty good, especially if opponent was raising with AK.
