C[White 62: (M) Could try killing the group, but black could push
up above 47, save the cutting stone, and create all sorts of trouble. 62
is enough.

C[White 78: (M) Lunatic. It must be at 81. I had failed to spot that
80' at 81 would get black 80 gaining a liberty and killing outright.

C[Black 85: (S) Should be at 88 (A), followed by white 207, black 208,
white 211, black 214, white 209, black 216 leading to a ko which is
favourable for Black (See variation).
(M) Probably black would end up killing six white cutting stones (22
etc) with his ko threat. This would be very good for Black.
