At the same time, Isildur1 sat for some heads-up $500/$1,000 No-Limit Hold'em with Phil Ivey. Ivey stuck around for almost 200 hands, losing $85k in the process.

Up next came the main event of the day where Isildur1 and Townsend sat for 1,000 hands of $200/$400 PLO.

Despite the limit being less than half of what Isildur1 has been playing over the last week, Townsend still managed to win over $1.1 million.

Rather than making his profit from record setting pots, Townsend ground out the massive win from a series of pots worth no more than $305k.

When Townsend left the tables with his profit, Isildur1 turned his sights back on his most lucrative high-stakes rival, Tom Dwan.

Over 542 hands of $300/$600 PLO Isildur1 managed to take another $175k from Dwan, who continues to struggle in the midst of a massive multi-million-dollar downswing.

Finishing off the action for the day was high-stakes regular Ilari "Ziigmund" Sahamies. Sitting at $500/$1,000, Isildur1 lost $267k to the Finnish action player before throwing in the towel.

At the end of the day Isildur1 finished his session down over $976k.
