Isildur1, who took the poker world by storm after winning millions of dollars, then losing and winning millions of dollars again in the 12 biggest pots in online poker history against some of the game's biggest names, is Viktor Blom.

Blom knew the end of his anonymity was near when he signed with Team PokerStars Pro, which belongs to the largest online poker cardroom in the world, in December 2010, still as Isildur1 at the time.

In the end, Blom decided to make his identity public on Saturday at the PokerStars Caribbean Adventure tournament in the Bahamas.

The 20-year-old from Ed in western Sweden near the Norwegian border is the youngest of four children and now lives in London. His older brother Sebastian also plays poker and recently won a Swedish Championships title online, Aftonbladet reported.

Blom began playing poker when he was 14.

"In the beginning, it was just for fun," he told PokerStarsBlog.com of his early games with his friends.

By the age of 18, he was playing 15 hours a day online.

"I deposited $2,000 (14,000 kronor) and within three weeks, I had $2 million," he told PokerStarsBlog.com.

Not long after, he attracted attention with his extremely aggressive and fearless style of play. It was a perfect complement for Heads-Up No-Limit Hold'em, in which he is probably among the best players in the world, and he started to rack up millions of dollars under the Isildur1 moniker.

However, learned the hard way that it is far easier to lose than win millions and lost $3.2 million after a week of play against Phil Ivey, widely regarded as one of the best all-round players in the world, in November 2009.

He followed up this loss by taking on Finnish player Patrik Antonius in Omaha, a game in which he lacked experience. He lost $3 million to Antonius after only one day of play, which at the time was the largest single day gain and loss in the history of online poker. The following day, he won $2 million back from Antonius.

Less than a month later, Blom lost $4.2 million in five hours against Brian Hastings, although it was later discovered that Hastings and two other players had colluded with one another and compiled over 30,000 hands of Isildur1's plays. Blom later lost a further $1.5 million against Hastings in another session.

At the height of the intense scrutiny after his public became public, Blom has declined all interview requests.

"I had some rough days. But I'm not worried. I know I can always win money," he told PokerStarsBlog.com.

Besides his new found fame, Blom may also have to contend with the long arm of Swedish tax authorities.

Last week financial daily Dagens Industri reported that the Swedish Tax Agency (Skatteverket) announced it was going to look into internet poker companies which claim to be based overseas but nevertheless have much of their operations based in Sweden.

According to calculations done by the newspaper, Blom could owe up to 1 billion kronor ($149 million) in Swedish taxes.

However, the tax authorities refused to confirm or deny whether Blom was in their sights.

"Internet poker is something we're looking into and I know this poker player, but I can't comment on whether we've opened a case," tax agency spokesperson Erik Boman told the Dagens Nyheter (DN) newspaper.
