We don't know exactly how it played out, but what we do know is Sam Stein was all in and at risk against Patrick Smith in a huge pot preflop.
The winner of this pot was going to have around 350,000 in chips jump rocketing whoever won to the top of the chip counts. Once everything was set the dealer spread a flop giving Smith a huge advantage going to the turn and the river.
A on the turn was not the card Stein needed, a jack and a jack only could save Stein. The on the river made it official and Stein's tournament life was over.
