Finnish high roller Ossi “Monarch” Ketola defeated Poker Hall of Famer Patrik Antonius in a $20 million heads-up match during the Triton Poker series in Jeju, marking the largest livestreamed poker contest on record. Each player bought in for $10 million for the showdown.
The match swung wildly in the early stages, with Ketola landing a daring bluff worth $3 million holding only six-high, forcing Antonius to fold top pair. That moment appeared to shape Antonius’s later decisions, including a correct river call with queen-high against Ketola’s eight-high.
Despite controlling much of the early action, Ketola suffered a brutal setback when a $5.2 million pot turned against him after Antonius rivered a stronger two pair over Ketola’s bottom two pair, briefly giving Antonius the chip lead.
The lead changed hands again when Antonius, betting aggressively with ace-high on a queen-high board, gave up on the river and lost a massive pot to Ketola’s top pair, pushing Ketola back into a near 2:1 advantage.
Ketola continued applying pressure, including another successful bluff with six-high that took down a multi-million-dollar pot. The turning point came when he flopped top pair and a straight flush draw with Q♥9♥, then completed a straight flush on the turn, extracting a massive check-raised pot after Antonius correctly folded a made straight facing a $4.1 million shove.
On the following hand, Antonius got his stack in preflop with A♦K♦ against Ketola’s K♣J♣, but a J♠ turn sealed his fate. Antonius’s $10 million loss stands as the largest single-match defeat in livestream poker history.
