solution says: The favorite's task is to kill. The favorite counts his exclusive liberties. The underdog's task is Seki. The underdog counts his exclusive plus all inside liberties. Seki - same amount of liberties. I agree with seki, but I disagree with your counting: favorite 7+9=16 liberties (7 for the eye and 9 outside) underdog 7+8+3=18 liberties (7 for the eye, 8 outside and 3 inside) underdog reaches his task - seki. favorite is 3 moves behind killing!
