For an online poker site still trying to regain its credibility in the wake of cheating scandals and a starring role in a 60 Minutes expose, UltimateBet.com took a big step backwards over the weekend with hand number 1162170993.  It appears that the one and only Phil Hellmuth mucked his hand but still won a $5,599 pot.

When he was made aware of it, UltimateBet’s COO, Paul Leggett, quickly addressed this latest problem on the UltimateBet Blog: “Earlier today we learned about a poker hand where our system paid out the losing player instead of the correct winning hand.  The hand number is #1162170993. We are investigating this software malfunction as our absolute top priority. This is the first incident of this kind we have encountered. We are currently examining the poker system and the application logs in order to pinpoint the cause of this malfunction.”

No word if Phil Hellmuth’s super-user account had been locked yet.
