It's generally accepted [0] that there's more variability in male IQ than in women (with the averages still being about the same). So the effect is that there are more extremely intelligent men in the world than women (and, conversely, there are more extremely dumb men than there are women).

Assuming IQ and chess ability are correlated, this would explain the lack of women at the top tiers of chess playing.
