Gus Hansen loses most of his chips

We caught up with Gus Hansen on the turn with the board reading KK36.  Hansen bet, his opponent raised to 5400, Hansen raised an additional 8k more, and his opponent called all in for less.  Hansen showed 33 for a flopped full house, and his opponent had K4 for trip kings.  The river was the case king to give his opponent quads, and Hansen is down to just over 5k.
