108: If I'm not mistaken A3 and G1 both give B+3.5 whereas A2 gives
B+1.5 so komi could be 9.5 but there would still be two solutions.

113: Black can also start with E8 and still have sufficient ko
threats.

125: B1 also kills.

128: D2 kills, not C2.

130: D2 becomes more complicated but looks good enough to win with
komi 7.5.

131: It looks like B4 wins by 3.5 and D1 by 1.5 so komi should be 9.5
to give a unique winning move.

139: C2 and B1 also live.

143: I don't see how A3 could win the semeai. A2 and C4 look more
effective.

148: D1 also wins?
