Joe Sebok just caught some bad luck that wasn't entirely due to the cards. The last player to act after the flop made a confusing action, which the dealer interpreted as a check. As the dealer put out the turn card, the player protested, saying he was going to bet. A floorperson was called over, and it was decided to burn that card and deal a fresh turn card after the player acted.
Unfortunately for Mr. Sebok, the new turn card gave Victor Ramdin trips, and with betting the rest of the way, Sebok ended up losing a large pot, dropping down to 41,000. Ramdin has about 53,000.
