I looked at the report and would like to give my opinion on why the
programs played as they did in the commented game between Zen and
Aya.
In the game white 106 threatens to capture the left side and most
importantly avoid the dangers of a huge semeai. If black does not
play 111 the game is over without a fight. After white 112 at least
black has a chance that white blunders and get a seki or wins a
semeai in the center.
Saving the white group with 112 is only big if the black group dies.
But it must die - unless the white central group dies. And the white
central group can get out with n13, can't it?
It can get out, but it is not that easy to read out. And this
uncertainty is what strong players (and MC programs) try to avoid.
Anyway, assuming you are right, may I quote you in my report?
Sure. Maybe that maight provoke some even stronger player to give an
even better analysis.
Later on in the game white takes the ko at J11 for move 134 and
after a ko threat black captures the right side group but white get
the big left side for sure and a large endgame move at the bottom,
for a clear won position, which illustrates the one sided nature
of this game after move 105.
By the way the main meaning of 105 is to threaten the center white
group since if black tries to surround the white group white can
connect and live with all white stones with 105.
So in my opinion both programs played well moves 106-112. White
simply played forcing moves that defended a won position and black
tried to keep the game complex enough in order to have a
possibility of winning.
