Why is there a tournament for champion of Britain or Brazil or Egypt? You can say it’s stupid that they should just let anyone compete! The champion of Belgium is a meaningless title! No, it encourages play amongst Belgian players, even if it’s not as important.
Why are there senior tournaments? Same reason. It gives them a reason to play.
If there’s a senior or Belgian or woman player who can compete in the big tournaments, you let them. The other tournaments are less important but that doesn’t mean that they shouldn’t exist.
When we will see the next Judit Polgar this claim will be wrong
I mean judit was never the world champion nor was she even a top rated player(or even among the top 5 rated players) so even if we do get another judit it won't mean anything
If we do see another Judit, it would mean everything. Iirc, FIDE is made up of 13% women and females make up for 1% of the total grandmaster population. Might be outdated. With these abysmally low percentages, having another Judit so soon would mean that the only thing limiting women's top level appearances would be the fact that there's just more men playing chess. If the percentages were proportional I believe more talented women would rise to the top.
