I've been dipping in and out of the snooker this week, and a bit came up this afternoon about the women's world championship, and the fact that 2 women are now qualified to go on the main tour.
Anyway, they mentioned in passing that the first transgender (MtF) snooker player had got to the semi finals (Jamie Hunter).
Now obviously there is no obvious physical disadvantage to women playing snooker (except I suspect height and reach will still make a difference), but there is obviously a women's competition for a reason....
A teen boy hanging out playing pool/snooker would be a lot more usual than a teen girl, so at the age Jamie was developing their skills, a girl would be much less likely to have felt welcome?
