"Playing six-player games rather than head-to-head requires a fundamental change in how AI develops its playing strategy," said Brown, who joined Facebook AI last year. "We are happy with its performance and believe that some of the strategies to play Pluribus might even change the way pro plays the game." The Pluribus algorithm creates some surprising features in its strategy. For example, most human players avoid "no bets" - that is, end one round with a call but then start the next round with bets. This is seen as a weak step that usually does not make strategic sense. But Pluribus bet more often than the professionals he defeated.

With poker being widely recognized as the most effective game capturing hidden information challenges, researchers have used it as a challenge in AI. However, no machine can truly defeat a human player in a multi-player setting, the format is usually followed in playing poker. But this changed with the introduction of Pluribus. Pluribus competes against some of the best poker players in the NLHE Six-max game. The machine is faced with a group of successful six-max specialists, who have revenues of more than $ 1 million.

Poker robots are the subject of two separate experiments. In the first example, the researchers used five humans and one AI format (5H + 1AI), while in the second experiment, five copies of Pluribus and one human player (1H + 5AI) played against each other, but bots could not communicate or collude with any way. The results of the trial showed that the bot's victory rate was significantly higher than that of human players.
