Ah, I played him in a 9x9 last night. I don't play bots often, but I was surprised at how early he knew he was defeated. :) He did make a few poor moves, mostly placing a stone into atari for no reason. But on the whole he did pretty well. Much better than I could do. :) Shawn > in case anyone is interested.
