Hm... I haven't forgotten so much Go that I can't spend the evening beating a totally newbie at 9x9, giving him 3 stones. This was a coworker who'd expressed an interest in learning Go. He still seemed reasonably enthusiastic by the end, and I thought I was going to lose the last game until he kept playing into a capture race that he wasn't going to win. I hope he doesn't pick up too many bad habits from playing me.
