Patrik Antonius and the mystery high stakes poker player ‘Isildur1’ were battling it out in $500/$1000 pot-limit Omaha when history was made. Antonius was sitting with $439,000 and Isildur1 was sitting with a stack around $450,000 as the two got the stacks in on the turn creating a pot valued at $878,958.50. This ridiculous pot which was won by Antonius as he spiked a straight on the river went down as the largest omaha pot in online poker history. Omaha is one crazy game and when you throw high stakes in the mix then a pot like this was just a matter of time.
