According to the ESPN crew, Brian Rast was just all in and at risk preflop with ace-king against the pocket aces of Ken Yamamoto and spiked a king on the flop and river to double up in fortunate fashion. Reduced to 14,000 earlier, Rast has recovered and doubled to a healthy stack of 84,000.
That's still not the biggest stack at the table, though, as Aymon Hata and Chris Fraser have it beat, and Florian Duta is not far behind.
