While having a strong understanding of positional play, Polgár excels in tactics and is known for an aggressive playing style, striving to maximize the initiative and actively pursuing complications. The former World Champion Garry Kasparov wrote that, based upon her games, "if to 'play like a girl' meant anything in chess, it would mean relentless aggression." In her youth, she was especially popular with the fans due to her willingness to employ wild gambits and attacks. As a teenager, Polgár has been credited with contributing to the popularity of the opening variation King's Bishop's Gambit. Polgár prefers aggressive openings, playing 1.e4 as White and the Sicilian or King's Indian Defence with black, but she has also said her opening choices will also depend upon her trainer. Jennifer Shahade, writer and two-time U.S. women's chess champion, suggested that the influence of Polgár as a role model may be one of the reasons women play more aggressive chess than men. Describing an individual encounter with Polgár, former U.S. Champion Joel Benjamin said, "It was all-out war for five hours. I was totally exhausted. She is a tiger at the chessboard. She absolutely has a killer instinct. You make one mistake and she goes right for the throat."
