We don't know exactly what happened to spark it - although we think it may have been some heckling from the rail that kicked it off - but there is some serious tension brewing between Kevin Boudreau and Chance Kornuth.
We witnessed two hands.
Boudreau raised to 125,000 on the button and Kornuth called in the big blind. They checked the board down to the river, when Kornuth bet out 225,000. Boudreau called and turned over for a flush - but then mucked his other two cards when Kornuth turned over for an ever-so-slightly better flush.
Some words were exchanged but the only bit of it we caught was, "Chance, you're crazy," from the mouth of Boudreau.
Next hand, Boudreau opened for 125,000, under the gun this time. Kornuth called from the small blind and they saw a flop. They both checked.
Kornuth bet out 160,000 on the turn and Boudreau called; Kornuth checked the river. Boudreau bet 225,000.
Maybe 30 seconds had elapsed when Boudreau asked the tournament director, "Can I call the clock? How long has it been?"
Replied TD David Klein, "Not long enough."
Kornuth called, and mucked as soon as Boudreau turned over .
Boudreau turned to his cheering rail and bellowed, "PAID OFF LIKE A FISH! PAID OFF LIKE A FISH!"
He sat back down and told Kornuth, "You used to be so much fun, Chance, Now I want to bust you every hand."
As we said, we don't actually know what sparked this off, but we do know that Boudreau was threatened with a penalty if he didn't calm down, the rail were ordered to stop heckling, and the waiters have been ordered not to serve any drinks to the rail.
