One of them is 29-year-old Brian Edwards of Jacksonville, Fla., a Web site administrator for Blue Cross Blue Shield, who says he's probably the only bot programmer who hasn't run his system online against humans.
"It's definitely possible to create a poker robot that plays better than yourself," Edwards said.
He told U.S. News & World Report he considers himself a midrange player and that he's about broken even in the two years he's been playing.
"Teaching a computer to play poker is different from teaching yourself," he said. "A human brain works with fuzzy knowledge and is able to make generalizations."
Pokerbots are a thorn in the side of online casinos. Internet sites such as Partypoker ban robots and hire employees to try to weed them out, the report said.
