Barry Denson, an ex-Territorial Army Soldier from the U.K., played poker for 120 hours and 20 minutes recently in Manchester at the G Casino.
Phil Laak's world record, set in 2010, had Laak playing 115 consecutive hours at the $10/$20 cash game at Bellagio in Las Vegas.
Denson's record has not been verified by Guinness World Records but he has paperwork and video footage confirmation that he is sending in.
On beating Laak's record by more than five hours, Denson tells how he prepared for the trial:
"I prepared for the feat by gradually shortening my sleep over the period of a few weeks until I was running on less than three hours sleep a night and this did help tremendously," Denson told PokerNews on Monday. "I expected to experience side effects. Phil Laak spoke after his record of experiencing visual hallucinations but my experience was slightly different in that I experienced aural hallucination. At one stage I was sure that I could hear small children laughing and playing around the slots which were quite close to the table."
Both Denson and Laak won during their marathon play and both donated their winnings to charities.
