Monarch Claims Victory with Straight Flush in Record $20 Million Heads-Up Match Against Patrik Antonius

Ossi “Monarch” Ketola defeated Poker Hall of Famer Patrik Antonius in a $20 million heads-up match, the largest ever in livestream poker history. Each player bought in for $10 million during the Triton Poker series in Jeju. The Finnish high rollers produced an intense battle filled with massive pots, aggressive bluffs, and decisive swings.

Record Pot Swings and Aggressive Plays

Monarch held the lead early but lost a $5.2 million pot after flopping bottom two pair, only for Antonius to river a stronger two pair and take a temporary chip lead. Monarch responded in a subsequent hand with Q ♦ 3 ♦ for top pair on a 10 ♦ Q ♣ 2 ♥ 6 ♠ board, calling bets from Antonius’s A ♦ 5 ♦ ace-high before regaining a nearly 2:1 advantage. Monarch also executed multiple bluffs, including one risking $3 million with six-high and another $3 million bet into a $2.2 million pot with six-high against eight-high.

The Decisive Straight Flush Hand

In the final stages, Antonius limped for $100,000 on the button with K ♦ 9 ♠. Monarch raised to $350,000 with Q ♥ 9 ♥ and checked top pair plus straight flush draw on the Q ♠ 8 ♥ J ♥ flop. After check-raising the turn 10 ♥ that completed his straight flush, Monarch check-raised the river to put Antonius all-in for $4.1 million. Antonius folded his straight. The next hand saw Antonius all-in preflop with A ♦ K ♦ against Monarch’s K ♣ J ♣, but a jack on the turn ended the match.

As reported by PokerNews, Antonius lost his full $10 million stake, the biggest single-match defeat in livestream poker history. Monarch had previously lost $15 million in a heads-up contest last year. The match featured additional notable hands, including Monarch calling a six-figure river bet with queen-high against eight-high and extracting value with top two pair.
