I got similar pleasure to chess out of number theory. I could never prove Goldbach's Conjecture, however.
Hobbies Better Than Chess
I act professionally with regional theatre groups, i play the saxaphone, i play baseball, i ski, i read (mostly shakespeare), i ride my bike, play ping pong, throw darts. And then of course I play chess (though I'm not very good. my USF rating is only like 1010. My online rating is in like the high 1400's though!). I'm a pretty busy 13 year old. :P
Watching UFC. UFC is like chess, but the stakes/consequences are much higher for the competitors.
Ultimate fa$%#ot cuddling.
Say that to Anderson Silva's face. Then read some of Reuben Fine's writing on the psychology of chess.
Nah, he'd probably start hugging me or something, and I'm not into dudes.
What other hobbies do you chess players participate in?
I have a wife, a kid, a house, a garden, and a research job. Five hobbies is a bit much, but I need them to fill the few moments per day I feel there should be more to life than chess.
I always thought there should be more to life than doing the chores.
I play tennis, cello, I use computer science to write fun programs, I mess around in linux, I play lots of board games (settlers of catan, puerto rico), I build weird things, and I'm a math and physics major.
Chess is great. It's something, one of the very few things, that really has a one to one correspondance between what you put in and what you get out of it. No luck, no one else's fault but your own.
I've always read there is 0% luck factor in Chess but I disagree. You can make a mistake and be lucky that your opponent didn't see it, assuming you go on to win the game.
penspinning, not many people even know what it is :P
Just out of interest, are you asian? Cos most of the people in my school who penspin are.
i dont know if you count "gettin comfortable" with my wife as a hobby but thats about the only thing i enjoy more than playing chess; and truely after a certain age im sure me and the wife "gettin comfortable" will come much less often and chess will be there waiting for me...oh wait, i enjoy smoking more than chess and drinking a good cup of coffee...however mix the three together after gettin comfy with the wife and thats heaven

Study of history....or science....or relgion. Ok, academic study of anything.
