Xie Jun v Ketevan Arakhamia-Grant, women's world championship candidates, Groningen 1997. Material is level, but White's game looks close to strategic defeat. The c3 knight is attacked, while after 1 Nb1 or 1 Nd1 Black simply captures Qxe4+ exchanging queens with an extra pawn and the superior position. China's Xie Jun, who went on to win the world title, found a subtle and imaginative move in the diagram which turned the tables and led to rapid victory for White. What happened?
