Ossi “Monarch” Ketola has defeated Patrik Antonius in the largest heads-up match in the history of livestreamed poker. Each player bought in for $10 million at Les A Casino in Jeju, South Korea, as part of the Duel Heads Up series at the Triton Poker Super High Roller Series Jeju II. The match lasted more than four hours, ran near-even for most of it, and ended on back-to-back hands: a straight flush that Antonius correctly folded to, and then a river jack that handed Ketola the match as a 70% favorite going in. Antonius absorbs a $10 million loss, the biggest single-match defeat in livestream poker history. Ketola takes the $20 million.
Antonius Came In Nervous
Patrik Antonius is 45 years old and has played in the biggest cash games in the world for more than two decades. He is a Poker Hall of Famer. He has won $11 million online, holds the record for the largest pot in online poker history, and has two Triton titles. He came to the table visibly nervous. Those watching the stream noticed immediately, uncharacteristic for a player of his stature, in a format he has played his entire career. A $10 million buy-in is not Antonius’s first high-pressure situation. The nerves were a sign of how seriously he took what was in front of him.
It showed early. In the first significant exchange, Ketola held nothing but six-high and moved $3 million into a $2.2 million pot. Antonius folded top pair. The opening bluff landed; Ketola had the read on his opponent from the start, and the match was underway.
Four Hours, Near-Even, Antonius Fighting Back
What followed was not the rout the opening bluff might have suggested. For most of the next four hours, the stacks stayed close. Antonius settled into the match, found his rhythm, and pushed back. He called a six-figure river bet from Ketola with queen-high and was right to do so: Ketola held eight-high. He caught the bluff, won the pot, and the chip counts leveled.
The match swung on a $5.2 million pot where Ketola flopped bottom two pair and led until Antonius rivered a stronger two pair to take the pot and edge into a slight chip lead. Ketola clawed it back on the very next significant hand, holding Q3 for top pair on a Q-high board while Antonius fired ace-high through the flop and turn before giving up the river, pushing Ketola back to roughly a 2:1 lead.
Antonius extracted maximum value in another hand, raising to $1,125,000 on the river with top two pair and getting called. He then three-bet with 9-8 suited before folding to a four-bet. The match stayed alive, competitive, and largely unresolved deep into the evening. Ketola held a small chip advantage for most of the final hour, but nothing that Antonius could not overcome with one big pot.

With the pot at $2.2 million, Ketola fired $3 million on the river with six-high, overbet bluffing into a pot he had no right to win. Antonius tanked and found the fold. A monster bluff that got through at a critical moment. It was not the only one. In a later hand, Ketola bet $3 million on the river with six-high again, this time into a pot of $2.2 million. Again it got through, Antonius letting go of eight-high. Two bluffs of that scale in the same match. Both landed.
The Straight Flush and the Sick Fold
The penultimate hand of the match produced one of the great folds in the history of high-stakes poker. Ketola held Q♥9♥ and Antonius limped in with K♦9♠. Ketola raised to $350,000; Antonius called. The flop came Q♠8♥J♥, giving Ketola top pair and a straight flush draw. He checked. Antonius bet his gutshot straight draw for $175,000. Ketola check-raised to $525,000 and was called.
The 10♥ landed on the turn, completing Ketola’s straight flush and leaving Antonius drawing dead with his turned Broadway straight. Ketola checked again. Antonius, unaware he was drawing dead, bet $625,000 into the made hand and was check-raised to $1,600,000. He called before the brick 3♣ arrived on the river.
Ketola put Antonius all in for $4.1 million. Antonius went deep into the tank with a Broadway straight, the kind of hand players very rarely fold in any context, and found the lay-down. He was right. The straight flush was on the other side. It was a fold that will be discussed for years: tanking with the second-best possible hand in the situation, and getting it right.
The Bad Beat That Ended It
The straight flush did not end the match. That was the remarkable part. Antonius survived, bloodied but still in it with amazing equity to nearly even the stacks once again. One hand later, he got his chips in preflop in the best possible spot: A♦K♦ against Ketola’s K♣J♣ on a four-bet jam for $4.1 million. Antonius was a roughly 70% favorite. The J♠ landed on the turn. Ketola made a pair of jacks, the better hand, and the river was irrelevant. The match was over.
It was the cruelest possible ending to a match Antonius had competed in seriously for more than four hours. He folded a straight to a straight flush, survived, and then lost as a favorite on the last hand. Ketola wins $20 million. Antonius loses $10 million in the biggest single-match defeat in the history of livestreamed poker. Both players partner up in the $200,000 Triton Invitational starting Saturday at Les A Casino.
