Clarifications and comments (some pre emptive)
Chess has a women's category to boost participation and spotlight female players.
Women can and do compete in the open category, which allows men and women. However, currently the highest rated women perform under the super closed "Super GM" level, so they participate in the tournaments that are less prestigious but fitting their rating. Male players like IM Eric Rosen also participate in such tournaments.
The best female player in history , Judit Polgar was 8th best in the world when taking both genders into account. There's nothing stopping women from reaching the elite level in open chess. She even participated in the candidates tournament which decides who gets to play against the world champion for the world champion title. Unfortunately she didn't perform too well, but it's not because of her gender, she was basically beaten 2-1 (plus draws) by a male competitor, just like the other contestants in the round she was eliminated.
At her peak she had 2735 Elo points, making her 55th highest rated person in the history of organized chess. This is higher than one of the actual challengers to the crown, Nigel short.
Regarding the rulings:
- No one is going to pretend to be a woman, in order to convert the person's identity with fide, they are required to have government issued paperwork saying they have transitioned. It's not worth it.
- it's funny that male to female transgender people are not regarded as women by this ruling, hence cannot participate in women's events, but female to male transgender people also forfeit their women's titles as they are not seen as women either. (To be fair, they can convert them to open titles, and get them back if they detransition officially)
So according to FIDE, transitioning from a man to a woman doesn't make you a woman, you are considered a man, but also, transitioning from a woman to a man makes you a man, so you are also not considered a woman.
Seems paradoxical. You'd think they'd pick one and stick to it.
Also: chess does have physical advantages, but they seem to be reletive and not competitive. Most high level players have some sports regimen as it helps increase cardiovascular efficiency, but size of competitor doesn't seem to matter as seen by David Bronstein and Mikhail Tal. Ian Nepomniatchschi intentionally lost weight for the world championship, and his ratings grew as a result.
Remember that whales are not necessarily more clever than humans even though their brains are huge in comparison.
