CHESS / Killer queen

WHEN men sacrifice their queens, it is a sign of misogyny, according to Ernest Jones. Freud's pupil was the perpetrator of the Oedipal chess theory: love your mother, kill your dad and you'll be a grandmaster. His theories, however, do not explain today's game from the Battle of the Sexes tournament in Vienna, in which Maya Chiburdanidze, the former world women's champion, sacrificed her queen to beat Bent Larsen.

White's 7. Qe2, apparently looking for a quick attack with 0-0-0 and g4, was met by resolute action in the centre, designed to take advantage of the stifled bishop on f1. Chiburdanidze found a good positional plan with Nc5, Nxe6, g3 and Bh3, but Black looked comfortable.

The first crisis came with 20 . . . Nd4. After 21. Bxd4 exd4 22. Rxd4 Qe4 23. Rhd1 g6 24. Bh3 Black has enough for the pawn, so Chib sacrificed rook for knight instead. Continuing to attack instead of regaining material with Ng6+, she was brilliantly justified by 31. Qxh6+]] with mate in three.
