I agree with most of your points, but I do think that ZS is a bit too hard, as I have recently played at least 30 times and humans have won only twice during those games. In that case, would anyone care to post some good strategies to help humans win more often? I think I should get my own sub-forum exclusively for all my questions and topics, as I am very active and post a lot of topics. Admins, what do you think?
