Sorry I'm not sure what you're trying to say.

Are you saying that Americans should lose more in film directed at Americans? It's not that it doesn't happen. It's just that it's hard to do. An example that immediately came to mind is the ironically named (for this conversation) show, "The Americans", where the Russians definitely win more than they lose. From Wikipedia:

"The series's final season earned Rhys the Primetime Emmy Award for Outstanding Lead Actor in a Drama Series, while Weisberg and co-lead writer Joel Fields won Outstanding Writing for a Drama Series; it was also awarded the Golden Globe Award for Best Television Series – Drama. Additionally, Margo Martindale won the Primetime Emmy Award for Outstanding Guest Actress in a Drama Series twice for her performance in the third and fourth seasons. It also became one of the rare drama shows to receive two Peabody Awards during its run."

It's easily my favorite show.

Looping back to Queens Gambit, I think the basic idea is that it's juuuust unrealistic enough without being too unreasonable to take you out of it. It's not unrealistic that Americans can be the best at chess. Hell, an American faced Magnus last world championship for the title and is still world #2. It's also not unrealistic that a Woman could get there as well. Hou Yifan is 84th right now.

But the combination is just unrealistic enough without taking you out of it, which makes it very entertaining.

A documentary about an orphan Russian or Chinese guy who ascends to the top? Might be more realistic, but not a good enough story for a Netflix #1 level of entertainment to a US audience.
