One of Katchalov's biggest scores in a live tournament came in a $5,000 no-limit event during the 2007 Bellagio Cup III, where he earned $118,785. He also won the Sunday $750,000-guaranteed tournament on Full Tilt in November of 2007, but nothing compares to the more than $2.4 million that he snagged for winning the 2007 World Poker Tour Doyle Brunson Classic. Katchalov entered the televised final table as the chip leader and rode it all the way to victory.
