Since October 2010, I often play go during my free time. My current level is 1 dan (or an almost equivalent European version). If you are near Paris and you would like to play, I usually enjoy playing free games...

When I was younger, I played a lot to Word in Flames, which rules are much more complex than go, but which is also one of the most interesting strategic games. Yeah, there is now a nice computer version of this game.
