Winner's Reaction
Dieleman reflected on his journey with calmness, describing both Day 1 and Day 2 as steady experiences.
“See, yesterday went extremely smooth, and then, yeah, same as today, actually,” he said. “Yeah, not any very big all-ins, mostly small pots and all the all-ins I won, and then only when we got 3-handed, it got a bit harder. Yeah, good and then it was just a roller coaster heads-up.”
When asked if playing for such large amounts of money affected him, Dieleman said. “Mm, not really, you do get used to the stakes quite quickly, I think, and I do play high stakes cash games online mostly. So I'm somewhat used to the money, but like this is a lot of course, and just started playing tournaments more seriously for the past 1.5 years.”
He also spoke about adapting from cash games to tournaments with the help from close friends. “I have some very good friends that are very good at tournaments like Tom Vogelsang, yeah, we're very good friends.”
It was also Dieleman’s first time playing in Merit, and he was impressed with everything about the venue. “It’s amazing, like everything is taken care of very well. The hotel is extremely beautiful. Also, this whole venue it's a very nice environment to play. Yeah, and every time you wake up, you're excited to play again.”
As for what comes next, Dieleman already has plans. “Yeah, actually for a few days, playing a 25k and then back to Amsterdam.”
Dieleman's Journey to the Top
Once late registration closed after roughly three hours of play, the field stood at 49 entries and only three tables remained. With seven places in the money, it did not take long for the action to reach the final table, where just two more eliminations were needed before the remaining players were guaranteed a six-figure payday. Among those who fell short were Richard Gryko, Poker Hall of Famer Nick Schulman, and Sean Rafael, who exited on the final table bubble.
Dieleman entered the final table as chip leader, but quickly surrendered it after Dvoress knocked out Manuel Stojanovic in ninth, then immediately burst the money bubble on the next hand by turning a straight to send Raphael Schreiner out as the last player to leave empty-handed.
It took only eight hands for the field to shrink from seven to four, with Dieleman responsible for one of the eliminations. He rivered a set of kings to beat Jesse Lonis’ set of queens, ending the Onyx SHRS NLH Invitational champion’s run in sixth place. Soon after, Fahredin Mustafov, who was looking to earn valuable Onyx Player of the Series points, was undone by Dieleman’s turned flush and had to settle for a finish just outside of the podium.
When three-handed play began, Dieleman held a slight lead over Dvoress while Nesterenko was clearly in last position. Dvoress chipped up slowly to overtake the Dutchman, but Nesterenko doubled up through him several times, allowing Dieleman to reclaim the top spot. Dvoress eventually bowed out in third in a huge clash when his turned flush lost out to Dieleman’s rivered full house, leaving only two players at the table.
Heads-up started with Dieleman holding a better than 2:1 advantage, though Nesterenko doubled quickly to take the chip lead for the first time in the day. With over 100 big blinds in play, the battle lasted more than 60 hands as the chip lead passed back and forth multiple times.
Eventually, in the final hand, where both stacks were nearly even, all the chips got into the middle on a connected flop, and Dieleman had another chance to finish it. Nesterenko held the nut straight while Dieleman had a flush draw. The turn completed the flush, and with it Dieleman locked up the title, the trophy, and the $750,000 top prize. Nesterenko collected $522,000 as runner-up, while Dieleman celebrated the biggest win of his career.
That concludes PokerNews coverage of the inaugural 2025 Onyx Super High Roller Series presented by Onyx Club from the Merit Royal Diamond Hotel Casino & Spa.
Level 24
: Blinds 250,000/500,000, 500,000 ante
Sergei Nesterenko raised the button to 1,500,000 and Marcus Dieleman defended out of the big blind.
When the 7♦6♠9♦ flop came down, Dieleman bet the pot for 3,500,000 and was met by a shove from Nesterenko for around 7,000,000. Dieleman called and he had his third chance to close out the event.
Sergei Nesterenko: A♣10♥9♥8♣ 
Marcus Dieleman: K♦5♦4♦2♣
Nesterenko flopped the nut straight and needed to dodge Dieleman's flush draw on the turn or river to take a commanding chip lead again.
However, the J♦ rolled off on the turn to give Dieleman a flush and leave Nesterenko drawing dead. An irrelevant A♦ completed the board, and Nesterenko was out in second, while Dieleman was the winner of the tournament.
