Ensan, who emigrated from Iran to Germany 30 years ago, defeated Italy's Dario Sammartino and Canada's Alex Livingston to claim top spot after a nail-biting 8-hour marathon session - becoming the third poker player born in Iran to have won the prestigious competition.

The final moment came at 1.24am local time when Sammartino pushed all in on what would ultimately prove to be a losing hand, giving the tournament - and $10 million (€8.9 million) - to the German.

He went into the final day with 60 percent of the chips before Sammartino rallied to claim a short-lived lead before Esnan powered through for the victory.

"Unbelievable," Ensan said when asked how he felt after claiming the multi-million dollar prize. "I am so happy. I thank my fans at home in Germany, also in Iran and my fans, my buddies here. This is the best feeling in my life."

It was a good-natured contest on the final table, with Ensan and Sammartino displaying excellent sportsmanship throughout, even fist-bumping after winning hands.

Sammartino will take home a prize of $6 million (€5.3 million) for finishing in second place while Livington - a former professional chess player - won $4 million (€3.5 million).
