Martin Jacobson, 27, won the title in Las Vegas, beating the Norwegian Felix Stephensen and coming home with USD 10 million in prize money, the equivalent of SEK 74 million.
Jacobsson won with three tens against Stephensen's pair of nines, according to ESPN, and Jacobsson told the news outlet after winning, "There's no such thing as a 'perfect tournament,' but this was close to perfect, maybe."
The last time a Swede played in the finals in Las Vegas was in 2006, when Erik Friberg came in eighth place. The Series is said to have been founded in 1970.
Lina Olofsson, the chair of the Swedish Poker Association, tells news agency TT that she hopes Jacobson's victory sparks a political debate about poker, which is often understood to be a game of chance, rather than a one of skill.
"Poker has a somewhat bad reputation, but it's so big. It's a game which requires you to think, like chess or bridge, and I hope more people start to realize that."
