I'm a little embarrased to say this, but I'm quite intimidated by women who are good at chess (not normal good, but talented good).
Mind you, I have no problems with smart or intelligent females of any kind and I hope that one day, my future wife will be extremely sharp, witty, etc.
But females who are talented at chess are a different story. They use their intelligence to plan and scheme and attack, and to devise fiendish traps for their opponents. They're not just smart, they're smart at being devious.
That just has way too many implications for a relationship of any kind.
I like, and prefer women who are intelligent. Much more of a challenge. If you beat her at chess all the time, then it will get boring, but if it is a challenge, THEN things get interesting...and that goes for everything, not just chess.
