Which sport could a woman most likely beat a man in?

Curling ...

Yes, curling!

Swimming!

Marriage.

This could happen at the amateur level but on the pro level, the men play way better than the women. They can give women all kinds of handicaps, usually referred to as "spots" in the pool world.

However, I suppose this holds true for any sport. Women can play against men when it's just two amateurs going at it but on the pro level there aren't any sports women can compete with men. This is not a knock on women, it's just that men have more muscle tissue than women. That's all...

Is chess a sport?

I like chess a lot but I haven't seen any pro chess tournaments featuring women that can play with men. Maybe there are??? idk..

Bowling's a sport, dude.

I think, though, this is a difficult question to answer as so many variables would have to go into it for a clear answer. 

Like, if a woman who was in the same kind of shape as a man, was just as experienced in a sport as a man and played the same way that man played and they played in a very sterilized environment, then it'd probably end up in a draw. But, if you took your average woman versus your average man, and the man would most likely win each time.
