Martin Jacobson, 27, a Swedish man who got his start playing online poker while he trained to be a chef, won the top World Series of Poker event Tuesday night, walking away $10 million richer. Jacobson had three 10s to beat Felix Stephenson of Norway and his pair of 9s. Jacobson showed a calm stillness through two days of playing poker. Unlike some other players, he didn’t wear sunglasses, a hoodie, or baseball cap to hide tells. He often stared at opponents, blinking through black-rimmed glasses. Stephenson, 24, took home $5.1 million for second place. For the first time, none of the final three players in the tournament were American.
