Why Poker Is a Big Deal for Artificial Intelligence

Playing poker involves dealing with imperfect information, which makes
the game very complex, and more like many real-world situations.

A win for Libratus would be a huge achievement in artificial
intelligence. Poker requires reasoning and intelligence that has
proven difficult for machines to imitate. It is fundamentally
different from checkers, chess, or Go, because an opponent’s hand
remains hidden from view during play. In games of “imperfect
information,” it is enormously complicated to figure out the ideal
strategy given every possible approach your opponent may be taking.

“Whether a move is good or not depends on things you cannot observe,”
says Vincent Conitzer, a professor at Duke University who teaches AI
and game theory. “This also results in a need to be unpredictable. If
you never bluff, you are not a good player. If you always bluff, you
are not a good player. Game theory tells you how to randomize your
play in a way that is, in a sense, optimal.”

So when the future AGI gives you advice on how to run your life,
remember it might be bluffing!  :}
