With the board reading , nothing happened. By which we mean there was a pause while the player who was first to act considered his options. Greg Mueller in position was impatient though.
"Dealer, can you please watch the action so we know what's going on?" he said, somewhat snappishly.
The dealer looked a little confused. "I don't know what's going on," he hazarded eventually. Finally the player checked and Mueller checked behind.
They saw a river and the unknown player bet out. Mueller now raised all in for his whole 10,000 stack, enough to cover his opponent, and after a little while the hapless player folded leaving himself just 1,525. Mueller upped his stack to 18,000.
After the hand Mueller tried to apologize to the dealer, although he actually in the process managed to further imply that the dealer was not fully focused on the task at hand. The dealer nodded a lot and said it was all right.
