Go

The Japanese board game,that is. I got hooked on it some years back, but never played until I got online. Still not great, rarely break above 20 kyu (very weak).

Hopefully will become a stronger player.

If you're interested in Go, the best site to check out is http://senseis.xmp.net Sensei's Library, the Go Wiki, There are several real-time and turn-based/play by email servers, the main one I play at is Dragon Go Server http://www.dragongoserver.net .

For those who read manga, you'll know of Hikaru no Go...the whole of the manga is based on Go.
