What's the age cutoff here?
are the boys better than girls in the chess?!!

Thats why boys should learn chess before adolescence---chess should be their first love. After the hormones start raging---its too late (generally). Who's going to be thinking about chess when there is a girl on your block that is drop dead gorgeous.
No way Jose!

Boys are just more competitive so more boys end up being good at chess.
I believe that males are not significantly innately better than females at chess. Perhaps gender roles and other social differences can account for differences in performance.

Statistically speaking, registered male chess players are better than registered female chess players by about 100 rating points (depending on the player pool); it has been proven that this difference is not due to participation rates. It's impossible to determine the reason for the ratings difference; whether it's an innate difference in ability or a matter of social pressure could be investigated if all players registered and maintained a rating as soon as they started playing as children (assuming that this would eliminate the effect of social pressure during adolescence). This has not been done, and therefore, no conclusion can be drawn on the subject.

You misunderstood. Boys are not innately better just innately more competitive thus ending up better at chess.

How about the Polgar sisters? What would you say about that?

What about them? Interestingly enough, Judit Polgar, who is considered the best female player of all time, peaked at a rating just about 100 points below Garry Kasparov, who is considered the best male player of all time. But you can't make statistics with only a single player's rating.

Girls are better than chess.
Amen
P.S
if you ask my wife she will tell men are better at chess because men sit around all day playing chess while the woman is looking after everything else.

I mentioned the Polgar Sisters in response of your suggestion that we could make useful conclusions "if all players registered and maintained a rating as soon as they started playing as children ". You supposed that starting to learn from childhood would be enough to see if girls are equally good as boys or not. Judith Polgar reached a *peak* rating that was 100 less than Kasparov's and Kasparov maintained that level of rating for a very long time. Also, most top rated women have started playing since their childhood. Yet, only one is in the top 100 list and the one that is there, Judith Polgar, is at place 51, 100+ points lower than the top 3 players.
yes
