Isildur1 out durrrrs Dwan for $1.2 million

In what might be the largest heads up session of the year, unknown Swedish player Isildur1 won over $1.2 million from Tom "durrrr" Dwan last night.

Take two of the most aggressive players in online poker, put them on multiple $500/$1,000 No-Limit Hold'em and Pot-Limit Omaha tables and you will end up with a flood of massive pots.

The session saw over $30 million wagered and 43 pots worth over $300k. The 100th largest pot of the night still came in at a hefty $200,222.

The two action-crazed players started their night at $300/$600 No-Limit Hold'em but after 582 hands Dwan was down over $134,000. They decided to switch to $500/$1,000 No-Limit Hold'em where they remained for over 6,700 hands.

On top of the NLH action, the players added 122 hands of $500/$1,000 PLO to the mix near the end of the session.

Despite having won five of the six largest pots of the night, Dwan failed to make a profit at any limit, Omaha or Hold'em, and ended the day down over $1,263,000.

The silver lining for Dwan is that he finally signed with Full Tilt as a member of the coveted Team Full Tilt this weekend. Check out the full story here.
