I used to play chess. Even read strategy books on it during my free period. At home if I had no one to play against i'd play myself... which is possible and less hard then you'd think.
That was gradeschool though, I bet i suck horribly now.
Lost interest after i figured out that there wasn't enough depth in chess. The first 3 moves or so are all going to be the same if you take it seriously and it's more about memorizing then strategy since just about every strategy in chess has already been invented.
So I tried to pick up Go! Sadly I can never find anyone to play me. I realize i could probably find an online Go! program though at this point i'd be such a beginner i probably wouldn't give any challenge to the hardcore Go! people that would play online.
