My AA against KK, both all-in pre-flop in late stages of a tourney...flop is A99, turn is a 9, river is a 9 and we split quad 9's with an A kicker.
Went out a few hands later to the chip leader.
This was on a site that shows the percentages as the cards come, and after the flop he had 0% chance...1% chance on turn.
