Early highlights included Antonius flopping a set of kings to crack Dwan's pocket aces and drag a $500k pot.
However, the real action began after 20 hours on the felt when all the other players had walked away from the game leaving just Ivey, Antonius and Dwan to play three-handed.
With blinds at $1,000/$2,000 with a $200 ante and more than $2.2 million on the table between the three, Dwan raised.
Ivey re-raised from the small blind and after Antonius folded the big blind, Dwan made the call.
Ivey fired $40k into the Q♣ 5♣ 3♦ flop and Dwan flatted. However, when the 4♥ fell on the turn and Ivey bet again, Dwan raised it up to a whopping $240K.
Ivey tanked, but emerged shoving. Dwan insta-called with 6♥ 7♥ for the nut straight and Ivey's A♣ 2♥ for the smaller straight was drawing dead, leaving Dwan to collect the massive $1.1 million pot.
Dwan also won the previous largest pot in televised poker history during Season 5 of High Stakes Poker when he flopped top pair and a flush draw against Barry Greenstein's pocket aces and turned trips to collect an amazing $919,600.
