Could it be that women miss some kind of quality that is benificial to play good chess?
And a fact that might be related to it: in the forty years I play now I did very seldom encounter homosexuals in the chess world, and if I did, they were not very strong.
Can it have something to do with competitiveness?

Oh, God... do you ask each of your opponents what their sexual orientation is?
