I just noticed this a few days ago — WinHonte
has been updated a level, and now supports 9x9 and 13x13 Go boards, as well as the standard 19x19. Actually, any square board 9 through 19 on a side. The AI is way too tough for me, of course. Go is like Rubik's Cube, I can only catch glimmers of what's going on, but it's still fascinating. With handicap, I can sometimes win, but only when the humiliation and aggravation manages to fire up a second layer of neurons.
