A poker hand that lost me a $17,300 pot

Yesterday night I was playing cash games along with a couple of big tournaments at Pokerstars. One of the poker tables was a $5,000 No Limit and I was doing pretty ok, until I got dealt Aces on the button. I ran into Kings in that poker hand and in the end we pushed all our chips in the middle preflop. The poker hand’s pot reached 17 thousand dollars and I consider it to be my biggest bad beat in terms of money in my online poker career. Here is the poker hand where I lost my biggest ever pot.
