I dont slowplay preflop with stacks this short, so I never see the spot. If I did, its the same like all other spots with KK on A high board. KK is a marginal made hand on AXX, so typically I would look to check the flop and either catch a
bluff or get thin value on the turn or river.
I dont see, what jamming the flop does. All better
hands call, and a lot of worse hands fold. I would rather keep those worse hands in the pot and allow them to bluff. If they have QJ on A73 rainbow, they are essentially drawing dead.
