No, I have not played Go...as for Ryuki asking what 'go' is, it's like board game...I don't know exactly how to describe it. But if you read the manga "Hikaru-No-Go", you'll get a better idea.
I've read some tutorials online, but I plan on getting a book on it soon. The key is to keep practicing. Every game I've played, I've lost, but I keep getting a little better.
