It has been generally assumed that Erik Sagström is the Swedish nickname Din_Fru at the high stakes games on Full Tilt Poker. However, a close friend of Sagström's denies the rumor. "I'm 100% sure it's not Erik," the player says to the Swedish newspaper Aftonbladet.

However, even the source (who wants to remain anonymous) doesn't know who is behind the nickname if not Sagström.

Sagström, 27, is a veritable veteran at the toughest online games and was first wreaking havoc on Ladbrokes and other European sites almost ten years ago. His various nicknames included "Erik123", "The Salmon", and "King of Ding". In 2003, Howard Lederer named him as the best young player in poker, and even Patrik Antonius says he learned a great deal from his early heads up games with Sagström. After paying his dues to the Swede, he went back down in stakes and skinned the other players using his new-found knowledge, the Finnish superstar once explained.
