Floor!
The board read x-K-10-J-x and both Lodden and his opponent checked the river.
At the showdown, Lodden's opponent turned over A-Q for a Broadway straight, while Lodden showed K-Q, for top pair and a busted straight draw.
The dealer mucked the A-Q and pushed the pot to Lodden, then proceeded to start shuffling the next hand. Players at the table called for the floor, who eventually ruled that Lodden must return the 23,600 pot to his opponent.
We should also note that there was a possible flush on the board, making Lodden's opponent's check on the river a legitimate one. A recently implemented rule here at the World Series states that if a player has last action and checks the absolute nuts, he would receive a one-round penalty for collusion.
