Chess mania
I hate chess, i love chess. A disease can not be cured.
Used to play in yahoo, but now more often in shredder computer chess. It's a PC chess program maker, but you can also play it online for free, no java, no flash, no rude players.
Good ways to learn more moves, tricks and to be careful on what you are guarding. Also available in google widget as daily puzzle, they call it.
