I don't see why this is a hard laydown against the right player.
There are I would say 3 people where i play 1-2NL that I would lay down the KK and to these 3 people it would be an easy laydown. To anyone else I'll pay off.
The only other possible hand that a player like this (ice) has is KK, and I allready have 2 of the Kings. As I think Cloutier says in his book, "it's not AK here, it's aces"
I have folded KK maybe 3 times preflop in cash games and I think it was the right move every time.
