If you’ve ever wanted to try chess for the first time, a good place to start is by playing email chess. Chessworld.net have a very easy interface to learn and you can pace yourself to play games whenever you like. The days-per-move can be anything from 1 upwards. I typically play 7 days or 10 days per move.
The fastest chess on the net is probably 1 minutes blitz games. If you have a desire for heart-pounding fun and a quick chess fix, try getting a copy of Fritz and playing on www.chessbase.com, or get an ICC account: http://www.chessclub.com/
What other game do you know where the game can last as short as 2 mins, or less, and as long as months or years even? (mind you, cricket can seem to last that long…)
