males like chess more than females do on average
but the thing is
I want to have a girlfriend who like chess
I'm old but not married
so I had dozens of girlfriends but
I broke up with my ex 2 months ago
and I found another new girl
but I just broke up with her a few hours ago
and she hated chess...

if the chessmen come with the shapes of barbie dolls or Mickey Mouse and its friends then she would like it...

the conclusion is
I want to have a girlfriend
who likes chess

so I guess males have natural ability and fondness toward chess

maybe males like chess
because males like this kind of things

also males' brain is customized in such a way that
males can calculate the movements geomatrically fast
and understand the interrelation and correlation among the pieces

can we think of other explanations on this profound and subtle topic?
