"But you're covering small examples when talking about women's results in chess. It's the same as Americans playing Go."
It's not at all like Americans playing go. Many Americans may not even know this game exists, let alone the rules. In fact I only learned the rules months ago, and have probably forgotten them. I had to learn them online and I'd probably have to search to find a Go set.
Chess, on the other hand, is a game virtually everyone knows about, at least in the US. Even if they don't know the rules, they know what it is on a basic level. And men and women have that same access to the game. Chess sets are incredibly easy to find, it's easy to find someone who knows the rules and teach you, there are chess books at the bookstore, etc etc. It's not like Americans and go.
If I grew up with go instead of chess, then I would probably have been trying to get good at go in the same way I have been trying to get good at chess. I just knew chess was a complex board game and I could try to move up in the ranks. I didn't even know what go was.
Well in chess, they are less successful as a group. Perhaps you meant, they have the same capacity to be successful (in chess) as men?
