Let’s Get Ready to Rumble
The feud between Daniel Negreanu and Annie Duke is widely considered the longest, most personal rivalry in poker history spanning over two decades. In the late 1990s, before either player was a household name, there was actually a level of mutual respect. However, Negreanu claimed that during his rookie years grinding in Las Vegas, Duke treated him with immense contempt and repeatedly berated his play at the table.

World Series of Poker Ladies Event
The rivalry eventually heated up concerning the World Series of Poker (WSOP) Ladies Championship. Duke strongly opposed women's-only events, arguing they were counterproductive to true sexual equality and should be abolished. Negreanu aggressively defended the Ladies Event, stating it provided a welcoming environment for women who didn't want to deal with toxic behavior from men at open tables. The debate boiled over during the 2010 WSOP when a few male players entered the Ladies Event in drag as a protest. When Duke publicly supported the men for "standing up for sexual equality," Negreanu blasted her stance and labeling her hypocritical as she was marketing herself as "the best female poker player in the world" while simultaneously belittling female-specific designations.

2010 Interview and the "C-Word" Controversy
The bad blood reached its absolute worst point later in 2010. During an interview with a UK poker magazine, Negreanu launched an incredibly harsh, expletive-laden tirade against Duke, using the "c-word" to describe her. The comments triggered an immediate uproar within the poker community. Duke seized the moment, writing a highly publicized open letter to Negreanu’s corporate sponsor PokerStars demanding they address his sexist language. While Negreanu eventually issued an apology to women in general, he refused to apologize directly to Duke.

End of the Rivalry
As the years went on Negreanu's attacked Duke's professional ethics. When the UltimateBet cheating scandal broke, Negreanu condemned Duke for her role as spokesperson and defender of the site. He publicly labeled her manipulative and arrogant using his massive platform to ensure the poker world did not forget her association with the scandal. Ultimately, Negreanu won the war of public perception. While Duke essentially exited the poker community in 2012 to pursue her career in cognitive psychology. Negreanu remained the face of modern poker.
