Some talk of Judit Polgar, and some of Xie Jun, the highest-rated woman player and the women's world champion respectively, but of all the world's great chess heroines, there is none that can compare with Vera Menchik, for whom a 50th anniversary memorial tournament is being played at Oakwood House in Maidstone, Kent.

Born in Russia (although of Czech nationality) in 1906, Menchik became the first woman world champion in 1927 and held the title until her death in a London air raid in 1944. The only woman of her time to play in top-level tournaments, she defeated so many top players that her victims formed a notional 'Menchik Club'. Their undisputed leader was Max Euwe, who lost to her twice before he became world champion.

Menchik's style was patient and positional, usually not incisive enough to threaten the greatest players but powerful in overcoming lesser opposition, as the following game, from Hastings 1928-9 shows.
