First-ever win against the World Champion

The World Chess Championship 1984 match between Anatoly Karpov and Garry Kasparov had many ups and downs, and a very controversial finish. Karpov started in very good form, and after nine games Kasparov was down 4–0 in a "first to six wins" match. Fellow players predicted he would be whitewashed 6–0 within 18 games. In an unexpected turn of events, there followed a series of 17 successive draws, some relatively short, and others drawn in unsettled positions. Kasparov lost game 27 (5–0), then fought back with another series of draws until game 32 (5–1), earning his first-ever win against the World Champion.
