ELI5: Why are males and females separated in non-physical competitions such as chess?
gpt
While there is physically nothing that keeps men and women from competing on the same level in chess, there are several societal factors in play that mean women do not play chess as frequently as men do. The chess organisation made a decision to instate a separate woman's only chess division (the regular chess division welcomes both men and women) to give female chess players more publicity. That publicity is important because that is one of the things that will eventually get more young girls interested in the sport and potentially get to a level where they can compete. If you never ever see a female chess player, you might quickly assume that this is not a sport for you and drop it. 

Hopefully, eventually, when the pressures that keep young girls from being as interested in chess no longer exist and the numbers of men and women competing are more even, a separate woman's division won't be needed any longer, but for now, it is.
