Looking for an SGF file demonstrating Go rules. Seemed like someone would have created one, but I have been unable to find it.
There are a number of good resources on the web, but I don't know of any SGF tutors.
KGS has a decent tutorial: http://www.gokgs.com/tutorial/index.jsp However, the "AI" that you play against simply plays random moves, so it's not much help as a tutor.
www.goproblems.org is good for people seeking to improve, but probably isn't good for total beginners.
The British Go Association website has a number of learner resources: http://britgo.org/intro/intro2.html
including a "capture go" java applet http://britgo.org/junior/capturego
Hope this helps. C
I don't know of any SGF file either, but I am particularly fond of The Interactive Way To Go. Not exactly teaching material, but whenever I gave an introduction (not that often) at least one participant had found the page already.
